Origin story: Rewriting human history through DNA

For most of our evolutionary history—for most of the time anatomically modern humans have been on Earth—we've shared the planet with other species of humans. It's only been in the last 30,000 years, the mere blink of an evolutionary eye, that modern humans have occupied the planet as the sole representative of the hominin lineage.

Southern white rhinos are threatened by incest and habitat fragmentation

noreply@blogger.com (Unknown) at The Archaeology News Network - 13 hours ago
The fragmentation of natural habitats by fences and human settlements is threatening the survival of the white rhinoceros. It prevents dispersal from the family group and leads to mating among close relatives. Additionally female rhinoceros favour individual males for mating over others and sire several offspring with the same partner over consecutive breeding periods. These factors lead to a high degree of inbreeding. The results come... [[ This is a content summary only. Visit my website for full links, other content, and more! ]]
