Huge growth in use of quartz for tools shows sophistication of ancient communities
A growth in the use of crystal quartz to make tools thousands of years ago shows the sophistication of ancient communities, according to new research.
The mineral was chosen because of its powerful symbolism, even though it involved painstaking work and othermaterialsthat would have been easier to use were available to prehistoric toolmakers, archaeologists argue.
Archaeologists have found there was a sudden spike in the number of tiny hand-made tools of less than 1cm made of crystalquartzin southern Africa around 14,000 years ago.
