A previously undetected Homo sapiens population inhabited what’s now southwestern China around 14,000 years ago and contributed to the ancestry of ancient Americans.
This far-ranging Asian group’s evolutionary identity has been revealed thanks to ancient DNA extracted from a skullcap previously excavated at Mengzi Ren, or MZR, a site in southwestern China’s Red Deer Cave, researchers report July 14 in Current Biology.
The finding offers a rare opportunity to narrow down where the ancestors of ancient Americans came from in East Asia’s vast expanse.
