Bill Gates says the rise of China is good for everyone and that Beijing needs to ‘play a stronger role in world governance’

Thu, January 26, 2023

Bill Gates sees China’s rise as a "huge win for the world.” But he knows that not everyone shares his view.

Speaking this week at the Lowy Institute, a think tank based in Sydney, the Microsoft cofounder gave his perspective on China’s transformation from a developing economy to a major world player.

“China has gone from in 1980 being incredibly impoverished—poorer than India, I mean literally, with starvation, malnutrition—to being the most wealthy middle-income country in the world,” said Gates. “It’s incredible, and it’s great for the world.”

The Microsoft billionaire, who currently ranks as the fourth richest person in the world, also warned about the negative attitudes toward China in the United States today, and vice versa.

“I do think the current mentality of the U.S. to China, and which is reciprocated, is kind of a lose-lose mentality,” he said. “If you ask U.S. politicians, ‘Hey, would you like the Chinese economy to shrink by 20% or grow by 20%,' I'm afraid they would vote that, ‘Yeah, let’s immiserate those people’—not understanding that for the global economy, the invention of cancer drugs, the solution of climate change, you know, we're all in this together."

The current hawkishness toward China in the U.S. could become “self-fulfilling in a very negative way,” he cautioned. He didn’t give an example. U.S. lawmakers voted overwhelmingly this month to establish a House select committee specifically to address the various threats that China poses to the U.S. GOP Wisconsin Rep. Mike Gallagher described a “coordinated whole-of-society strategy to undermine American leadership and American sovereignty” by the Chinese Communist Party.

Gates also noted China’s economic importance, saying it holds 20% of the world’s people.

“Their portion of the global economy and their portion of the global population match exactly. Countries like Australia, U.S., we have per capita GDPs five times what the Chinese have, so we have a disproportionate share of the world's economy."

But it wasn’t all rosy. Gates also leveled criticism at China. The country is "not a democracy," he acknowledged, and is an "outlier today in terms of that level of wealth and still being as autocratic as they are."

He also knocked China for not acting quickly enough to get its population properly vaccinated early during the COVID pandemic.

China “should have jumped on vaccines, particularly for the elderly, much faster, and that would have allowed them to open up somewhat sooner than they did,” he said.

China recently loosened its strict COVID restrictions and is reporting an uptick in COVID deaths as people circulate more freely, but the official numbers are likely far below reality. “We’ll never know the true death numbers,” Gates said.

Still, Gates said nations like China needed to step up on the world stage.

“The U.S. is politically weaker today, I would say, than it's been, and, you know, that's scary for the world,” he said. “The current world system is designed around U.S. leadership. As other countries have gotten richer, these middle-income countries including China and India need to play a stronger role in world governance."

China Sure to Hit Back Over Chip Controls, Japan Lawmaker Says

Thu, January 26, 2023 


(Bloomberg) -- China is “100% sure” to retaliate over Japanese backing for Biden administration restrictions on semiconductor exports, and firms facing the fallout should look for markets elsewhere, a ruling Liberal Democratic Party lawmaker said.

“China will come back with stronger retaliation and Japanese companies doing business there will probably be damaged,” said Shigeharu Aoyama, who serves on the party’s committee covering trade and industry. He made the comments in a Thursday interview with Bloomberg News after it reported the Netherlands and Japan are close to joining the US-led effort to restrict exports of the technology to China.

Japan and the Netherlands are home to key suppliers of semiconductor manufacturing equipment, but it is not yet clear what form their restrictions would take.

“They should take that as a turning point and look for other markets,” he added, saying he backed Japan’s participation in the measures.

US Poised for Dutch, Japanese Help on China Chip Crackdown

China is Japan’s largest trading partner and has said the US effort showed its “selfish hegemonic interest.” The Biden administration issued sweeping new rules in October that include restrictions on the supply of US manufacturers’ most advanced chipmaking equipment to Chinese customers and limits on Americans working for Chinese semiconductor firms, a move aimed at choking off access to certain expertise.

Dutch chip equipment giant ASML told Bloomberg the US-led measures could also push Beijing to develop its own technology in advanced semiconductor-making machinery.

Beijing last month filed a complaint with the World Trade Organization aimed at overturning the US-imposed export controls. It also has a history of deploying economic sanctions amid political disputes with its neighbors.

China Hits Back at South Korea, Japan in Covid Retaliation

Earlier this month, Beijing stopped issuing visas for travelers from Japan and short-term visitors from South Korea in retaliation for the two countries introducing Covid-19 testing and other restrictions on people traveling from mainland China.

In 2017, China also dramatically scaled back trade with South Korea after then-President Moon Jae-in agreed to host a US anti-missile system. And in 2010, China banned exports of rare earths to Japan as tensions rose over East China Sea islands claimed by both countries.

What the West Gets Wrong About China
Three fundamental misconceptions
HARVARD BUSINESS REVIEW
From the Magazine (May–June 2021)

Yukai Du

Summary. Many people have wrongly assumed that political freedom would follow new economic freedoms in China and that its economic growth would have to be built on the same foundations as in the West. The authors suggest that those assumptions are rooted in...more

When we first traveled to China, in the early 1990s, it was very different from what we see today. Even in Beijing many people wore Mao suits and cycled everywhere; only senior Chinese Communist Party (CCP) officials used cars. In the countryside life retained many of its traditional elements. But over the next 30 years, thanks to policies aimed at developing the economy and increasing capital investment, China emerged as a global power, with the second-largest economy in the world and a burgeoning middle class eager to spend.

One thing hasn’t changed, though: Many Western politicians and business executives still don’t get China. Believing, for example, that political freedom would follow the new economic freedoms, they wrongly assumed that China’s internet would be similar to the freewheeling and often politically disruptive version developed in the West. And believing that China’s economic growth would have to be built on the same foundations as those in the West, many failed to envisage the Chinese state’s continuing role as investor, regulator, and intellectual property owner.

Why do leaders in the West persist in getting China so wrong? In our work we have come to see that people in both business and politics often cling to three widely shared but essentially false assumptions about modern China. As we’ll argue in the following pages, these assumptions reflect gaps in their knowledge about China’s history, culture, and language that encourage them to draw persuasive but deeply flawed analogies between China and other countries.

[ Myth 1 ]

Economics and Democracy Are Two Sides of the Same Coin


Many Westerners assume that China is on the same development trajectory that Japan, Britain, Germany, and France embarked on in the immediate aftermath of World War II—the only difference being that the Chinese started much later than other Asian economies, such as South Korea and Malaysia, after a 40-year Maoist detour. According to this view, economic growth and increasing prosperity will cause China to move toward a more liberal model for both its economy and its politics, as did those countries.

It’s a plausible narrative. As the author Yuval Noah Harari has pointed out, liberalism has had few competitors since the end of the Cold War, when both fascism and communism appeared defeated. And the narrative has had some powerful supporters. In a speech in 2000 former U.S. President Bill Clinton declared, “By joining the WTO, China is not simply agreeing to import more of our products, it is agreeing to import one of democracy’s most cherished values: economic freedom. When individuals have the power…to realize their dreams, they will demand a greater say.”

But this argument overlooks some fundamental differences between China and the United States, Japan, Britain, Germany, and France. Those countries have since 1945 been pluralist democracies with independent judiciaries. As a result, economic growth came in tandem with social progress (through, for example, legislation protecting individual choice and minority rights), which made it easy to imagine that they were two sides of a coin. The collapse of the USSR appeared to validate that belief, given that the Soviet regime’s inability to deliver meaningful economic growth for its citizens contributed to its collapse: Russia’s eventual integration into the global economy (perestroika) followed Mikhail Gorbachev’s political reforms (glasnost).

Many Chinese believe that the country’s recent economic achievements have actually come about because of, not despite, China’s authoritarian form of government.

In China, however, growth has come in the context of stable communist rule, suggesting that democracy and growth are not inevitably mutually dependent. In fact, many Chinese believe that the country’s recent economic achievements—large-scale poverty reduction, huge infrastructure investment, and development as a world-class tech innovator—have come about because of, not despite, China’s authoritarian form of government. Its aggressive handling of Covid-19—in sharp contrast to that of many Western countries with higher death rates and later, less-stringent lockdowns—has, if anything, reinforced that view.

China has also defied predictions that its authoritarianism would inhibit its capacity to innovate. It is a global leader in AI, biotech, and space exploration. Some of its technological successes have been driven by market forces: People wanted to buy goods or communicate more easily, and the likes of Alibaba and Tencent have helped them do just that. But much of the technological progress has come from a highly innovative and well-funded military that has invested heavily in China’s burgeoning new industries. This, of course, mirrors the role of U.S. defense and intelligence spending in the development of Silicon Valley. But in China the consumer applications have come faster, making more obvious the link between government investment and products and services that benefit individuals. That’s why ordinary Chinese people see Chinese companies such as Alibaba, Huawei, and TikTok as sources of national pride—international vanguards of Chinese success—rather than simply sources of jobs or GDP, as they might be viewed in the West.

Thus July 2020 polling data from the Ash Center at Harvard’s Kennedy School of Government revealed 95% satisfaction with the Beijing government among Chinese citizens. Our own experiences on the ground in China confirm this. Most ordinary people we meet don’t feel that the authoritarian state is solely oppressive, although it can be that; for them it also provides opportunity. A cleaner in Chongqing now owns several apartments because the CCP reformed property laws. A Shanghai journalist is paid by her state-controlled magazine to fly around the world for stories on global lifestyle trends. A young student in Nanjing can study propulsion physics at Beijing’s Tsinghua University thanks to social mobility and the party’s significant investment in scientific research.

Many Chinese believe that the country’s recent economic achievements have actually come about because of, not despite, China’s authoritarian form of government.

The past decade has, if anything, strengthened Chinese leaders’ view that economic reform is possible without liberalizing politics. A major turning point was the financial crisis of 2008, which in Chinese eyes revealed the hollowness of the “Washington consensus” that democratization and economic success were linked. In the years since, China has become an economic titan, a global leader in technology innovation, and a military superpower, all while tightening its authoritarian system of government—and reinforcing a belief that the liberal narrative does not apply to China. That, perhaps, is why its current president and (more crucially) party general secretary, Xi Jinping, has let it be known that he considers Gorbachev a traitor to the cause for liberalizing as he did, thereby destroying the Communist Party’s hold on the USSR. And when Xi announced, in 2017, that the “three critical battles” for China’s development would fall in the areas of reducing financial risk, addressing pollution, and alleviating poverty, he also made it clear that the objective of these reforms was to solidify the system rather than to change it. The truth, then, is that China is not an authoritarian state seeking to become more liberal but an authoritarian state seeking to become more successful—politically as well as economically.

In much Western analysis the verb most commonly attached to China’s reforms is “stalled.” The truth is that political reform in China hasn’t stalled. It continues apace. It’s just not liberal reform. One example is the reinvention in the late 2010s of the Central Commission for Discipline Inspection. Empowered by Xi to deal with the corruption that had become so prevalent early in that decade, the commission can arrest and hold suspects for several months; its decisions cannot be overturned by any other entity in China, not even the supreme court. The commission has succeeded in reducing corruption in large part because it is essentially above the law—something unimaginable in a liberal democracy. These are the reforms China is making—and they need to be understood on their own terms, not simply as a distorted or deficient version of a liberal model.

One reason that many people misread China’s trajectory may be that—particularly in the English-language promotional materials the Chinese use overseas—the country tends to portray itself as a variation on a liberal state, and therefore more trustworthy. It often compares itself to brands with which Westerners are familiar. For example, in making the case for why it should be involved in the UK’s 5G infrastructure rollout, Huawei styled itself the “John Lewis of China,” in reference to the well-known British department store that is regularly ranked as one of the UK’s most trusted brands. China is also often at pains to suggest to foreign governments or investors that it is similar to the West in many aspects—consumer lifestyles, leisure travel, and a high demand for tertiary education. These similarities are real, but they are manifestations of the wealth and personal aspirations of China’s newly affluent middle class, and they in no way negate the very real differences between the political systems of China and the West.

Which brings us to the next myth.

[ Myth 2 ]
Authoritarian Political Systems Can’t Be Legitimate


Many Chinese not only don’t believe that democracy is necessary for economic success but do believe that their form of government is legitimate and effective. Westerners’ failure to appreciate this explains why many still expect China to reduce its role as investor, regulator, and, especially, intellectual property owner when that role is in fact seen as essential by the Chinese government.

Part of the system’s legitimacy in the eyes of the Chinese is, again, rooted in history: China has often had to fight off invaders and, as is rarely acknowledged in the West, fought essentially alone against Japan from 1937 until 1941, when the U.S. entered World War II. The resulting victory, which for decades the CCP spun as its solo vanquishing of an external enemy, was reinforced by defeat of an internal one (Chiang Kai-shek in 1949), establishing the legitimacy of the party and its authoritarian system.

Seventy years on, many Chinese believe that their political system is now actually more legitimate and effective than the West’s. This is a belief alien to many Western business executives, especially if they’ve had experience with other authoritarian regimes. The critical distinction is that the Chinese system is not only Marxist, it’s Marxist-Leninist. In our experience, many Westerners don’t understand what that means or why it matters. A Marxist system is concerned primarily with economic outcomes. That has political implications, of course—for example, that the public ownership of assets is necessary to ensure an equal distribution of wealth—but the economic outcomes are the focus. Leninism, however, is essentially a political doctrine; its primary aim is control. So a Marxist-Leninist system is concerned not only with economic outcomes but also with gaining and maintaining control over the system itself.

That has huge implications for people seeking to do business in China. If China were concerned only with economic outcomes, it would welcome foreign businesses and investors and, provided they helped deliver economic growth, would treat them as equal partners, agnostic as to who owned the IP or the majority stake in a joint venture. But because this is also a Leninist system, those issues are of critical importance to Chinese leaders, who won’t change their minds about them, however effective or helpful their foreign partners are economically.

This plays out every time a Western company negotiates access to the Chinese market. We have both sat in meetings where business executives, particularly in the technology and pharmaceutical sectors, expressed surprise at China’s insistence that they transfer ownership of their IP to a Chinese company. Some have expressed optimism that China’s need for control will lessen after they’ve proved their worth as partners. Our response? That’s not likely, precisely because in China’s particular brand of authoritarianism, control is key.

Yukai Du

A Leninist approach to selecting future leaders is also a way the CCP has maintained its legitimacy, because to many ordinary Chinese, this approach produces relatively competent leaders: They are chosen by the CCP and progress through the system by successfully running first a town and then a province; only after that do they serve on the Politburo. You can’t become a senior leader in China without having proved your worth as a manager. China’s leaders argue that its essentially Leninist rule book makes Chinese politics far less arbitrary or nepotistic than those of many other, notably Western, countries (even though the system has its share of back-scratching and opaque decision-making).

Familiarity with Leninist doctrine is still important for getting ahead. Entry to the CCP and to a university involves compulsory courses in Marxist-Leninist thought, which has also become part of popular culture, as evidenced by the 2018 TV talk show Marx Got It Right. And with handy apps such as Xuexi Qiangguo (“Study the powerful nation” and a pun on “Study Xi”) to teach the basics of thinkers including Marx, Lenin, Mao, and Xi Jinping, political education is now a 21st-century business.

The Leninist nature of politics is also evidenced by the language used to discuss it. Political discourse in China remains anchored in Marxist-Leninist ideas of “struggle” (douzheng) and “contradiction” (maodun)—both seen as attributes that force a necessary and even healthy confrontation that can help achieve a victorious outcome. In fact, the Chinese word for the resolution of a conflict (jiejue) can imply a result in which one side overcomes the other, rather than one in which both sides are content. Hence the old joke that China’s definition of a win-win scenario is one in which China wins twice.

China uses its particular authoritarian model—and its presumed legitimacy—to build trust with its population in ways that would be considered highly intrusive in a liberal democracy. The city of Rongcheng, for example, uses big data (available to the government through surveillance and other data-capturing infrastructure) to give people individualized “social credit scores.” These are used to reward or punish citizens according to their political and financial virtues or vices. The benefits are both financial (for example, access to mortgage loans) and social (permission to buy a ticket on one of the new high-speed trains). Those with low social-credit scores may find themselves prevented from buying an airline ticket or getting a date on an app. For liberals (in China and elsewhere), this is an appalling prospect; but for many ordinary people in China, it’s a perfectly reasonable part of the social contract between the individual and the state.

Such ideas may appear very different from the outward-facing, Confucian concepts of “benevolence” and “harmony” that China presents to its international, English-speaking audience. But even those concepts lead to considerable misunderstanding on the part of Westerners, who often reduce Confucianism to cloying ideas about peace and cooperation. For the Chinese, the key to those outcomes is respect for an appropriate hierarchy, itself a means of control. While hierarchy and equality may appear to the post-Enlightenment West to be antithetical concepts, in China they remain inherently complementary.

Recognizing that the authoritarian Marxist-Leninist system is accepted in China as not only legitimate but also effective is crucially important if Westerners are to make more-realistic long-term decisions about how to deal with or invest in the country. But the third assumption can also mislead those seeking to engage with China.

[ Myth 3 ]
The Chinese Live, Work, and Invest Like Westerners


China’s recent history means that Chinese people and the state approach decisions very differently from Westerners—in both the time frames they use and the risks they worry about most. But because human beings tend to believe that other humans make decisions as they do, this may be the most difficult assumption for Westerners to overcome.

Let’s imagine the personal history of a Chinese woman who is 65 today. Born in 1955, she experienced as a child the terrible Great Leap Forward famine in which 20 million Chinese starved to death. She was a Red Guard as a teenager, screaming adoration for Chairman Mao while her parents were being re-educated for being educated. By the 1980s she was in the first generation to go back to university, and even took part in the Tiananmen Square demonstration.

Then, in the 1990s, she took advantage of the new economic freedoms, becoming a 30-something entrepreneur in one of the new Special Economic Zones. She bought a flat—the first time anyone in her family’s history had owned property. Eager for experience, she took a job as an investment analyst with a Shanghai-based foreign asset manager, but despite a long-term career plan mapped out by her employer, she left that company for a small short-term pay raise from a competitor. By 2008 she was making the most of the rise in disposable incomes by buying new consumer goods that her parents could only have dreamt about. In the early 2010s she started moderating her previously outspoken political comments on Weibo as censorship tightened up. By 2020 she was intent on seeing her seven-year-old grandson and infant granddaughter (a second child had only recently become legal) do well.

Had she been born in 1955 in almost any other major economy in the world, her life would have been much, much more predictable. But looking back over her life story, one can see why even many young Chinese today may feel a reduced sense of predictability or trust in what the future holds—or in what their government might do next.

When life is (or has been within living memory) unpredictable, people tend to apply a higher discount rate to potential long-term outcomes than to short-term ones—and a rate materially higher than the one applied by people living in more-stable societies. That means not that these people are unconcerned with long-term outcomes but, rather, that their risk aversion increases significantly as the time frame lengthens. This shapes the way they make long-term commitments, especially those that entail short-term trade-offs or losses.

Thus many Chinese consumers prefer the short-term gains of the stock market to locking their money away in long-term savings vehicles. As market research consistently tells us, the majority of individual Chinese investors behave more like traders. For example, a 2015 survey found that 81% of them trade at least once a month, even though frequent trading is invariably a way to destroy rather than create long-term fund value. That figure is higher than in all Western countries (for example, only 53% of U.S. individual investors trade this frequently); it’s also even higher than in neighboring Hong Kong—another Han Chinese society with a predilection for gambling and a similar, capital-gains-tax-free regime. This suggests that something distinctive to mainland China influences this behavior: long-term unpredictability that’s sufficiently recent to have been experienced by or passed on to those now buying stocks.

That focus on securing short-term gain is why the young asset manager in Shanghai left a good long-term job for a relatively small but immediate pay raise—behavior that still plagues many businesses trying to retain talent and manage succession pipelines in China. People who do take long-term career risks often do so only after fulfilling their primary need for short-term security. For example, we’ve interviewed couples in which the wife “jumps into the sea” of starting her own business—becoming one of China’s many female entrepreneurs—because her husband’s stable but lower-paid state-sector job will provide the family with security. The one long-term asset class in which increasing numbers of Chinese are invested—that is, residential property, ownership of which grew from 14% of 25-to-69-year-olds in 1988 to 93% by 2008—is driven also by the need for security: Unlike all other assets, property ensures a roof over one’s head if things go wrong, in a system with limited social welfare and a history of sudden policy changes.

China’s rulers see foreign engagement as a source less of opportunity than of threat, uncertainty, and even humiliation.

In contrast, the government’s discount rate on the future is lower—in part because of its Leninist emphasis on control—and explicitly focused on long-term returns. The vehicles for much of this investment are still the CCP’s Soviet-style five-year plans, which include the development of what Xi has termed an “eco-civilization” built around solar energy technology, “smart cities,” and high-density, energy-efficient housing. Ambition like that can’t be realized without state intervention—relatively fast and easy but often brutal in China. By comparison, progress on these issues is for Western economies extremely slow.

Decisions—by both individuals and the state—about how to invest all serve one purpose: to provide security and stability in an unpredictable world. Although many in the West may believe that China sees only opportunity in its 21st-century global plans, its motivation is very different. For much of its turbulent modern history, China has been under threat from foreign powers, both within Asia (notably Japan) and outside it (the UK and France in the mid 19th century). China’s rulers, therefore, see foreign engagement as a source less of opportunity than of threat, uncertainty, and even humiliation. They still blame foreign interference for many of their misfortunes, even if it occurred more than a century ago. For example, the British role in the Opium Wars of the 1840s kicked off a 100-year period that the Chinese still refer to as the Century of Humiliation. China’s history continues to color its view of international relations—and in large part explains its current obsession with the inviolability of its sovereignty.

That history also explains the paradox that the rulers and the ruled in China operate on very different time frames. For individuals, who’ve lived through harsh times they could not control, the reaction is to make some key choices in a much more short-term way than Westerners do. Policy makers, in contrast, looking for ways to gain more control and sovereignty over the future, now play a much longer game than the West does. This shared quest for predictability explains the continuing attractiveness of an authoritarian system in which control is the central tenet.
. . .
Many in the West accept the version of China that it has presented to the world: The period of “reform and opening” begun in 1978 by Deng Xiaoping, which stressed the need to avoid the radical and often violent politics of the Cultural Revolution, means that ideology in China no longer matters. The reality is quite different. At every point since 1949 the Chinese Communist Party has been central to the institutions, society, and daily experiences that shape the Chinese people. And the party has always believed in and emphasized the importance of Chinese history and of Marxist-Leninist thought, with all they imply. Until Western companies and politicians accept this reality, they will continue to get China wrong.

California Wants to Ban Chrome Plating

Lawrence Hodge
Thu, January 26, 2023

California is about turn the state’s restoration, customization, and other automotive industries on its head. The state is looking to reduce harmful emissions and cancer-causing chemicals. The L.A. Times reports state officials have set their sights on banning a method of chrome plating that releases potentially deadly and cancerous chemicals.

The chemical used in the chrome plating process is called hexavalent chromium. It’s what gives the chrome its shiny finish. It’s used in everything from aviation components to household bathroom fixtures. It’s probably more widely used in the automotive community. Chromed bumpers and trim are the lifeblood of the restoration and hot rod communities. They’re not ready for it.

The problem happens during the chroming process. To get that clean, shiny luster, vehicles or their parts are dipped in a vat of solution containing hexavalent chromium. Then, a current of electricity is sent through the liquid so that the hexavalent chromium adheres to the part. At the same time, however, the current heats the solution causing both bubbles and vapor which carry the chromium. And it’s deadly, over 500 times more toxic than diesel fumes.

Some companies that engage in this process are aware of the vapors and use suppressants to try to reduce the fumes. But The Times points out that the suppressants just make matters worse: “These suppressants contain PFAS, another highly toxic compound, which is discharged into local waterways.” The whole process releases cancer-causing chemicals into surrounding communities, state officials say.

Because of this, the California Air Resources Board is proposing a ban of chromium or chrome-6 by 2027 and a ban on the use of the compound for industrial durability by 2039. But the board may have a fight on its hands as both the automotive restoration industry and many of the state’s industries that rely on the compound are up in arms. The board knows that this ban would have huge implications across industries statewide, acknowledging that several thousand jobs could be lost.

If the ban is approved, state officials are allocating $10 million per year for the first three years of the ban to help the industry transition. That transition into what exactly isn’t clear. Bryan Leiker, executive director of the Metal Finishing Assn. of California said that the industry isn’t ready. “California is trying to force something to happen that’s not ready to happen. The consequences are going to be disastrous because you can lose an entire industry,” he said.

California wants to ban the toxic chemical that gives chrome its classic shine

For decades, hexavalent chromium has provided the silvery showroom finish to countless consumer products, from automobile bumpers and grilles to kitchen faucets and light fixtures. It has also served as an indispensable rust-resistant coating for aviation components, such as airplane landing gear.

But while hardened chrome is harmless, the airborne emissions from the plating process are more than 500 times more toxic than diesel exhaust, and pose a substantial cancer risk to surrounding communities.

In light of these risks, the California Air Resources Board has proposed a landmark ban on the use of so-called chrome-6 in decorative plating by 2027, saying the health hazards of the plating process are borne disproportionately by low-income communities. The rule would also prohibit the chemical's use for industrial durability — such as providing anti-corrosive coatings — by 2039.


The proposal has drawn praise from clean air advocates but has also sent shock waves through the state's auto restoration and customization industries. It could also force California aerospace companies and defense contractors to accelerate research into less toxic alternatives.

"We would be the first jurisdiction in the world to phase out hexavalent chromium in the plating industry," said Jane Williams, executive director of California Communities Against Toxics. "Even the EU hasn't done it because they haven't found a substitute for crucial uses. We would be working with the industry and the military to actually identify new coatings. That's precedent setting."

The proposal, however, has been blasted by the chrome plating industry. Bryan Leiker, executive director of the Metal Finishing Assn. of California, said that these facilities are already required to comply with the strictest regulations in the nation, and that an outright ban would only compel businesses and jobs to leave California.

"California is trying to force something to happen that's not ready to happen," Leiker said. "The consequences are going to be disastrous, because you can lose an entire industry."

The Air Resources Board will hold the public hearing on the matter at 8:30 a.m. Friday in Riverside. Board members will vote on the final proposal in May.

In California, there are over 110 chrome-plating facilities, and more than 70% of them are located in disadvantaged communities. Los Angeles County in particular — with its abundance of car enthusiasts and top aerospace companies — has the greatest concentration of chrome platers in the nation.

From hot rods to low riders, life in Southern California is still synonymous with classic and customized cars of yesteryear, and chrome's legacy remains strong. Much of that has to do with the social influence chrome once held in a car-centric region that eagerly adapted itself to automobiles.

"Because you were in your car so much, it was another way of greeting the world," said Leslie Kendall, chief historian of the Petersen Automotive Museum in Los Angeles. "It was like your ultimate outer layer of clothing. Chrome on a car was like a brooch for a lady's coat, something that embellished the form."

But the mirror-like sheen on wheels, bumpers and grilles comes at a cost. This luster is achieved by dipping auto parts in industrial tanks with a liquid solution containing a potent carcinogen.

An electric current is sent through the tank, causing hexavalent chromium to adhere to the part. At the same time, however, voltage also causes the solution to bubble, releasing chromium-laden vapors as they burst.

Many of these operations try to reduce the vapors by adding chemical fume suppressants to the chromium solution. But these suppressants contain PFAS, another highly toxic compound, which is discharged into local waterways.

California identified hexavalent chromium as a toxic air contaminant that has no safe amount of exposure in 1986. Over time, people have become more concerned about the chemical's health consequences.

In 1998, community groups called for an investigation into a chrome-plating operation near Suva Elementary and Intermediate schools in Bell Gardens.

The groups suspected that chrome emissions had contributed to numerous health problems for children, teachers and residents. Twenty-two students and six teachers at the schools had been diagnosed with cancer in eight years, organizers say.

Several families, including those whose children died from cancer, filed a lawsuit against Chrome Crankshaft, a company that plated locomotive parts. The suit was later settled.

Since then, the state has adopted the nation's most stringent emission standards for chrome plating operations.

Today, about 9% of chrome platers in California operate within 1,000 feet of schools.

The metal finishing industry has argued its emissions pale in comparison with others'.

California's 58 large chrome platers produced less than 1% of hexavalent chromium pollution, according to state data. The vast majority comes from burning fossil fuels. Cement production and lumber industries also emit more.

"We're less than 1% of emissions statewide, but we're the only industry facing a ban right now," Leiker said.

Although the amount of total emissions may seem insignificant, state regulators and environmental advocates contend chrome plating facilities can drastically elevate concentrations in the areas immediately surrounding them, posing a long-term health threat.

The Air Resources Board hopes the proposed rule will encourage these facilities to switch to trivalent chromium, a far less toxic alternative, which has been available as a substitute since the early 1990s.

However, trivalent chromium has not been widely used in the decorative plating industry because its darker color is similar to stainless steel, an aesthetic that has not appealed to California car enthusiasts striving to re-create the high-gloss sheen of the 20th century.

"It's a different color and it just wouldn't look right on these older cars," said Elayne Bendel, who is on the board of the Lincoln and Continental Owner's Club Western Region. "It would never match what came out of the factory, let's say, in 1960 or sometime back there."

If California's chrome proposal is adopted, the Mission Viejo resident said, classic car owners here would probably have to send their parts out of state to have them chromed, making a difficult hobby even more expensive.

"There's a scarcity of labor, a scarcity of parts, and if the ability to get good chrome locally goes away, then that's just another aspect of the difficulty with owning these cars," Bendel said.

But chrome has been used for more than simply embellishing cars.

California is home to some of the world's largest aerospace companies and defense contractors. Trivalent chromium coating has not been proved to meet U.S. Department of Defense specifications for thickness, hardness and corrosion resistance.

"The Department of Defense is looking into less toxic alternative coatings to hexavalent chromium, including applications via additive manufacturing processes," Navy Lt. Cmdr. Timothy Gorman, a Pentagon spokesperson, said in a statement. "We will continue to work with our public and private industry partners and communicate on potential changes in this area.”

The California Air Resources Board acknowledges that the rule would have wide-ranging effects, and estimates that several thousand jobs could be lost in manufacturing and other sectors related to chrome plating.

The chrome plating facilities that remain will incur significant costs to transition to trivalent chromium plating, which the air board estimates would be around $323,000 for decorative platers and $4 million for industrial platers.

"It's completely new equipment, new solution, new process and new permitting," said Leiker, the metal finishing director. "It's not as simple as draining the tank and putting in the new solution."

If the rule is approved, the state Legislature has allocated $10 million a year, for the first three years, to assist chrome platers with the transition.

Lula calls on France's Macron to attend summit of Amazon countries

Thu, January 26, 2023


(Reuters) - Brazil's President Luiz Inacio Lula da Silva on Thursday urged his French counterpart, Emmanuel Macron, to have France attend the summit of the Amazon countries that he aims to host in coming months.


Lula, who was elected for a third term last October vowing to tackle deforestation in the rainforest, discussed in a phone call with Macron efforts to combat the threat posed by climate change, according to a statement from his office.

He talked about the importance of France attending a summit of the countries of the Amazon forest that Brazil plans to host in the next few month, as it is the only European country to share the biome, through its overseas territory of French Guiana.

Besides Brazil and French Guiana, seven other countries have territory in the world's largest rainforest.


Macron has meanwhile asked Brazil to attend its own "One Forest Summit" that France and Gabon will host in early March, according to the Brazilian statement.


Lula won a narrow election last year promising an overhaul in Brazil's climate policy, after deforestation in the Amazon reached its highest levels in 15 years under then far-right President Jair Bolsonaro, who undermined environmental law enforcement and pushed for more mining and farming in the region.

Bolsonaro had a strained relationship with Macron, after the French president denounced in 2019 surging fires in the Amazon. Bolsonaro responded by insulting Macron's wife and accusing him of disrespecting Brazilian sovereignty.

Later on Thursday, Macron said after speaking with Lula that he had reaffirmed his determination to take action "for the climate, biodiversity, our forests and against hunger."

"We will meet these challenges," he said.

Climate tipping points in Amazon, Tibet 'linked': scientists


Kelly MACNAMARA
Thu, January 26, 2023


Climate extremes in the Amazon rainforest are directly affecting those in the Tibetan Plateau, scientists said Thursday, warning that the Himalayan region crucial for the water security of millions was close to a potentially disastrous "tipping point".

Planet-heating pollution from human activities is raising global temperatures and scientists have said this is pushing crucial ecosystems and whole regions towards often irreversible changes.

Vulnerable areas include melting polar ice sheets that could cause metres of sea-level rise, as well as the Amazon basin, where tropical forests are at risk of turning into savannah.

But can one tipping point have a domino effect on another region? Recent research suggests this is already happening.

Climate-driven changes in the Amazon basin have knock-on effects on the Tibetan Plateau 20,000 kilometres (12,500 miles) away, scientists in China, Europe and Israel reported in Nature Climate Change earlier this month.

"We've been surprised to see how strongly climate extremes in the Amazon are connected to climate extremes in Tibet," said co-author Jurgen Kurths from Potsdam Institute for Climate Impact Research.

The researchers used global near-surface temperature data over the last 40 years to map out a pathway of climate links. They stretched from South America to Southern Africa, on to the Middle East and finally into the Tibetan Plateau.

In their study, the researchers then used computer simulations to track how global warming might change these long-distance link-ups out to 2100.

They found that when it gets warmer in the Amazon, temperatures also rise in Tibet. But when rain increases in the South American rainforest, snowfall decreases in the Himalayan region, sometimes called the "third pole".

- 'Tipping cascades' -


Using snow cover data, the scientists also detected what they say are early warnings the Tibetan Plateau has been approaching a tipping point of its own since 2008.

The Tibetan Plateau supplies a substantial proportion of the water needs of almost two billion people across South Asia, Southeast Asia and China.

Research published in Nature Climate Change last year said climate change could deplete terrestrial water storage over the Tibetan Plateau, which may ultimately threaten water availability downstream.

Other studies have shown a warming trend in recent decades in the region which -- like the Arctic region -- is warming two to three times faster than the global average.

But Kurths said the proximity to a potential point-of-no-return transition had been "overlooked so far".

The researchers said that while their study suggests a heightened risk of "tipping cascades" it was unlikely that the climate system as a whole would flip into a new state.

"Yet, over time, sub-continental tipping events can severely affect entire societies and threaten important parts of the biosphere," said co-author Hans Joachim Schellnhuber from PIK.

"This is a risk we should rather avoid."

To avoid the worst impacts of warming, countries have agreed to keep temperatures from rising above the limit of well below two degrees Celsius since the mid-1900s, and preferably below 1.5C.

For that to be achieved, planet-heating greenhouse gas emissions, mainly from fossil fuels, must decline some 45 percent compared to 2020 levels by the end of this decade, and to net zero by mid-century, according to the UN's climate science advisory body.

The Amazon Is Deteriorating Too Fast for Species and the Climate to Adapt



Carly Wanna
Thu, January 26, 2023 

(Bloomberg) -- Two new scientific review articles by international teams of researchers paint a bleak picture of the state of the Amazon rainforest: The critical ecosystem is being damaged at an unprecedented pace, they warn, which may usher in “a qualitatively different global climate regime” with grievous effects on biodiversity and human welfare.

The papers, both published in the peer-reviewed journal Science on Thursday, summarize research on deforestation and landscape degradation in the Amazon to deliver a sharp message. The region that is key to the world’s climate system “is now perched to transition rapidly from a largely forested to a nonforested landscape,” write one set of authors, “and the changes are happening much too rapidly for Amazonian species, peoples, and ecosystems to respond adaptively.”

The main culprits are human activities, such as logging and clearing forest for cattle pasture, as well as climate change.

“We know the two major drivers of deforestation are global climate change and regional deforestation,” said James Albert, a biologist at the University of Louisiana at Lafayette and lead author of one of the articles. “If you allow development to proceed unregulated, you will have an ecological disaster.”

Albert and his team analyzed data from the Science Panel for the Amazon Assessment Report, which documents changes to the Amazon’s ecosystem and biodiversity. Specifically, they compared how fast humans are changing the Amazon with the speed at which other natural processes are affecting it. They found that human factors are causing degradation and habitat destruction at a rate hundreds to thousands of times faster than natural phenomena are.

Already, 17% of the rainforest has been impacted by disturbances like logging, fires and road expansion, and 14% of it has been replaced with pasture or cropland.

The second review focuses on other human-caused factors that degrade the Amazon — including timber extraction, fire and extreme drought. By analyzing existing data, the researchers found that these impacts are degrading roughly 2.5 million square kilometers (965,000 square miles), representing more than one third of the region’s remaining forest.

According to lead author David Lapola, a research scientist at University of Campinas in Brazil, the analysis rounds out the focus on deforestation that characterizes much other Amazon research. “Even though we’ve been looking to the Amazon for quite some time with our scientific glasses, there are many processes directly caused by man that we’ve been ignoring,” Lapola said.

The researchers call for proactive measures to conserve the Amazon and broadly reduce global emissions, such as stronger forest-protection policies and a halt to international financing of market-driven land conversion. Brazil’s recently elected president, Luiz Inácio Lula da Silva, has pledged to safeguard the Amazon after damage to the rainforest accelerated under his predecessor, Jair Bolsonaro.

William Ripple, an ecologist at Oregon State University who did not co-author either article, said the reviews do “an outstanding job” documenting the Amazon in crisis: “This is an example of the toll humans are making on ecosystems all over the world, and at some point we will need to change our ways to survive.”


Amazon heat drives Tibet temperatures: climate tipping elements connected half around the globe

“Logging, road construction and warming are already today stressing the Amazon rainforest, and will likely do so even more in the future – and while the Amazon region is of course an important Earth system element by itself, it’s also a burning question if and how changes in that region could affect other parts of the world,” explains Jingfang Fan from Beijing Normal University, China, and the Potsdam Institute for Climate Impact Research (PIK) in Germany. “For the first time, we’ve now been able to robustly identify and quantify these so called teleconnections. Our research confirms  that Earth system tipping elements are indeed inter-linked even over long distances, and the Amazon is one key example how this could play out.”

Analysis of air temperature changes in 65.000 subregions in the past 40 years

The researchers analyzed near-surface air temperature changes in a grid of more than 65.000 subregions, regarded as nodes, they put on the globe, using data from the past 40 years. By doing so, they could see how changes at one node influenced those at another one. They succeeded to detect a pronounced propagation pathway over more than 20.000 kilometers –  from South America via Southern Africa to the Middle East and finally to the Tibetan Plateau. This pathway can be explained by the main atmospheric and oceanic circulation patterns.

In a next step, the researchers used state-of-the-art climate computer simulations to see how global warming, caused by greenhouse gas emissions from burning fossil fuels, might modify the long-distance linkages until 2100. “We’ve been surprised to see how strongly climate extremes in the Amazon are connected to climate extremes in Tibet,” says Jürgen Kurths from PIK, a co-author of the paper. “When it’s getting warmer in the Amazon, it also does so in Tibet, hence for temperature there’s a positive correlation. It’s different for precipitation. When we have more rain in the Amazon, there’s less snowfall in Tibet.”

The researchers detected the early warning signals based on the snow cover data and reveal that the Tibetan Plateau has been losing stability and approaching a tipping point since 2008. “This  has been overlooked so far,” says Kurths. Despite its remote location, the Tibetan Plateau is relevant for a lot of people’s livelihoods due to its role as an important water reservoir.

"This is a risk we should rather avoid"

“Our research underlines that tipping cascades are a risk to be taken seriously: inter-linked tipping elements in the Earth system can trigger each other, with potentially severe consequences,” says Hans Joachim Schellnhuber from PIK, also a co-author. “To be clear, it’s unlikely that the climate system as a whole will tip. Yet, over time, sub-continental tipping events can severely affect entire societies and threaten important parts of the biosphere. This is a risk we should rather avoid. And we can do so by rapidly reducing greenhouse gas emissions and by developing nature-based solutions for removing CO2 from the atmosphere.”

New geosciences study shows Triassic fossils that reveal origins of living amphibians

A team of Virginia Tech paleontologists, led by doctoral candidate Ben Kligman, have discovered the first Triassic-era caecilian fossils, the oldest-known of their kind, in Arizona.

The smallest of newly found fossils can upend what paleontologists know about our history.

A team of paleontologists from Virginia Tech and the U.S. Petrified Forest National Park, among others, have discovered the first “unmistakable” Triassic-era caecilian fossil — the oldest-known caecilian fossils — thus extending the record of this small, burrowing mammal by roughly 35 million years. The find also fills a gap of at least 87 million years in the known historical fossil record of the amphibian-like creature.

The fossil was first co-discovered by Ben Kligman, a doctoral student in the Department of Geosciences, part of the Virginia Tech College of Science, at Arizona’s Petrified Forest National Park during a dig in 2019. Named by Kligman as Funcusvermis gilmorei, the fossil extends the history of caecilians 35 million years back to Triassic Period, roughly 250 million to 200 million years ago.

Prior to this new study, published today in the journal Nature, only 10 fossil caecilian occurrences were known, dating back to the Early Jurassic Period, about 183 million years ago. However, previous DNA studies estimated evolutionary origins of caecilians back to the Carboniferous or Permian eras, some 370 million to 270 million years ago, according to Kligman, marking that 87-million-year gap. However, no such fossils had been found.

“The discovery of the oldest caecilian fossils highlights the crucial nature of new fossil evidence. Many of the biggest outstanding questions in paleontology and evolution cannot be resolved without fossils like this,” said Kligman, who previously discovered a 220-million-year-old species of cynodont or stem-mammal, a precursor of modern-day mammals. “Fossil caecilians are extraordinarily rare, and they are found accidentally when paleontologists are searching for the fossils of other more common animals. Our discovery of one was totally unexpected, and it transformed the trajectory of my scientific interests.”

The discovery of the fossils was made in 2019 by Kligman and Petrified Forest National Park student intern Xavier Jenkins, now a Ph.D. student at Idaho State University, while the duo was processing fossiliferous sediment from the park’s nicknamed Thunderstorm Ridge via a microscope. Funcusvermis was found in a layer of the Chinle Formation dated to approximately 220 million years ago, when Arizona was positioned near the equator at the central part of the supercontinent Pangaea, Kligman said. This region at the time was subject to a hot, humid climate. Today, Arizona is still hot, but has low humidity.

“Seeing the first jaw under the microscope, with its distinctive double row of teeth, sent chills down my back,” Kligman said. “We immediately knew it was a caecilian, the oldest caecilian fossil ever found, and a once-in-a-lifetime discovery.”

Previous to this find, the 87-million-year gap in the fossil record hid the early evolutionary history of caecilians, leading to a decades-long debate amongst scientists over the relationships of caecilians to their amphibian relatives, frogs and salamanders.

“Funcusvermis extends the humid equatorial pattern of occurrence seen in all known fossil and living caecilians, suggesting that the biogeographic history of caecilians has been guided by restriction to these ecological settings, likely due to physiological constraints linked to humidity, and constrained by the drift of continental plates into and out of the humid-equatorial zone after the fragmentation of Pangaea,” Kligman said.

Modern caecilians are limbless amphibians with cylindrical bodies with a compact, bullet-shaped skull that helps them burrow underground. Now exclusively home to South and Central America, Africa, and southern Asia, caecilians spend their lives burrowing in leaf-litter or soil searching for prey such as worms and insects. This underground existence has made studying caecilians difficult for scientists. Kligman, tongue in cheek, describes modern caecilians as an “eyeless sock puppet with the body of a worm.”

Funcusvermis actually shares skeletal features related more with early frog and salamander fossils, strengthening evidence for a shared origin and close evolutionary relationship between caecilians and these two groups. Funcusvermis also shares skeletal features with an ancient group of amphibians known to paleontologists as dissorophoid temnospondyls. Kligman adds, “Unlike living caecilians, Funcusvermis lacks many adaptations associated with burrowing underground, indicating a slower acquisition of features associated with an underground lifestyle in the early stages of caecilian evolution.”

Name that tune

Now, here’s the fun part: The genus name ‘Funcusvermis’ was inspired by the Ohio Players’ 1972 song “Funky Worm” from their album Pleasure, a favorite song of the authors that was often played while excavating fossils at Thunderstorm Ridge. ‘Funcus’ is derived from the Latinized form of the English word Funky for the upbeat, rhythmic form of dance music, while ‘vermis’ is derived from the Latin word for worm. (It’s an excellent song, by the way. Instant earworm, so to speak.)

The species name, gilmorei, honors Ned Gilmore, the collections manager at the Academy of Natural Sciences of Philadelphia’s Drexel University. (Kligman is from Philadelphia and volunteered with Gilmore’s herpetology wet collection as an undergraduate student. “He was an important mentor who helped inspire my interest in fossils and amphibians,” Kligman said.)

Co-authors on the study include Michelle Stocker, an assistant professor, and Sterling Nesbitt, an associate professor, in the Virginia Tech Department of Geosciences and members of the Global Change Center that is part of the Fralin Life Sciences Institute. Other authors include Adam Marsh, lead paleontologist; Matthew Smith, museum curator; and William Parker, chief of science and resource management, all at the Petrified Forest National Park; and Bryan Gee, postdoctoral fellow at the University of Washington’s Burke Museum and Department of Biology.

“As the eponymous song says, it's the funkiest worm in the world,” Marsh quipped.

Stocker added, “What we collect really determines what we can say about which animals that were present, how many of them there were, and what they looked like. Without using these methods for fossil collection and analysis we would be missing out on knowing so many important aspects of this Triassic ecosystem. Now that we have a search image of what bones to look for and how to look for them, it will be exciting to see what other fossil localities preserve these early lissamphibians.”

Nesbitt said finds such as this can reset the game board on paleontology, in the best sense of the phrase. “This find clearly demonstrates that some fossils that you can barely see can greatly change our understanding of entire groups that you can see today,” he said.

What’s happened since 2019

At the Petrified Forest National Park, where the initial discovery was found in 2019, the lower jaws of at least 70 individuals of Funcusvermis have been recovered as of summer 2022, making the area “the most abundant fossil caecilian-producing bonebed ever discovered,” Kligman said.

Only a handful of bones of Funcusvermis have been found, including upper and lower jaws, a vertebra, and part of a hind-limb, Kligman said. All of the found bones were disarticulated, not as complete skeletons. Without complete skeletons, Kligman and his fellow researchers cannot exactly determine the body length of Funcusvermis, but inferences from isolated elements, such as the lower jaw being less than a quarter of an inch long, indicate that Funcusvermis was a tiny animal.

“Since its discovery in 2017, the Thunderstorm Ridge site has produced a diverse assemblage of over 60 animals ranging from freshwater sharks to dinosaurs,” Kligman said. “Several other new species discovered at this site have been recently described. Many other new species from this site are currently under study and will be published in upcoming years.”

In other words, fully expect more upending of what paleontologists know about the history of fossils.

What crocodile DNA reveals about the Ice Age

Environmental drivers such as sea level affect genetic evolution and point to where conservation efforts may be focused

What drives crocodile evolution? Is climate a major factor or changes in sea levels? Determined to find answers to these questions, researchers from McGill University discovered that while changing temperatures and rainfall had little impact on the crocodiles’ gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.

“The American crocodile tolerates huge variations in temperature and rainfall. But about 20,000 years ago – when much of the world's water was frozen, forming the vast ice sheets of the last glacial maximum – sea levels dropped by more than 100 metres. This created a geographical barrier that separated the gene flow of crocodiles in Panama,” says postdoctoral fellow José Avila-Cervantes, working under the supervision of McGill professor Hans Larsson.

The researchers point out that the crocodiles are good swimmers, but they can’t travel long distances on land. As a result, the Caribbean and Pacific crocodile populations were isolated from each other, and consequently have undergone different genetic mutations.

The team compared the climate tolerance of living populations of American crocodiles (Crocodylus acutus) to the paleoclimate estimates for the region over the past 3 million years – the time span of extreme climate variation during the Ice Age.

“This is one of the first times Ice Age effects have been found in a tropical species. It’s exciting to discover effects of the last Ice Age glaciation still resonate in the genomes of Pacific and Caribbean American crocodiles today,” says Larsson, Professor of Biology at the Redpath Museum of McGill University.

“Discovering that these animals would have easily tolerated the climate swings of the Ice Age speaks to their resilience over geological time. Only humans in recent decades of hunting and land development seem to really affect crocodiles,” he says. The findings offer new insight into how environmental drivers affect genetic evolution and where conservation efforts of particular crocodile populations in Panama should be focused.

40,000-year-old cave full of animal skulls might be first known site of human rituals

Moira Ritter
Thu, January 26, 2023 

Click on the Facebook page of someone who hunts, and you might find a picture of them dressed in camo with black face paint streaked under their eyes, grinning while holding up the head of a buck.

New evidence shows that humans’ earliest ancestors might have had a similar idea.

A team of Spanish archaeologists recently unearthed a trove of large animal skulls in a 40,000-year-old cave, according to a Jan. 26 news release from the Community of Madrid. Experts say the findings could be the first evidence of ancient human rituals.

The skulls belonged to large ungulates — mammals with hooves, including horses, bison, deer and elk — and were found in Cueva Des-Cubierta, a known Neanderthal site that was originally discovered in 2009, the community said.

Unlike other, similar discoveries, archaeologists said the remains they found within the cave were not consistent with subsistence activities, but instead appeared to be symbolic.

Evidence at the site indicates that the mammals were killed and consumed outside of the cave, according to a study from the team released Jan. 26 in Nature Human Behavior. The skulls that were recovered all had appendages but were missing their teeth and jaws, leading experts to believe that they were used as hunting trophies.


Two rhinoceros skulls were found in the cave, archaeologists said.

Some of the smaller bones also showed signs of being cooked or burned on a hearth, the study said.

The evidence at Cueva Des-Cubierta is the first of its kind, indicating that Neanderthals may have had symbolic capacity, which means they held more intellectual capacity than previously known, the community said.

The team also identified more than 1,000 ancient tools, including anvils, hammerstones, cores, flakes and other shaped tools, they said in the study.

The cave is about 55 miles north of Madrid.

Google Translate was used to translate the release from the Community of Madrid.
