A few tribes in the Amazon forest have a small percentage of ancestry that seems closest to Andaman Islanders in the Indian Ocean. But nobody can come up with a plausible theory for how prehistoric people could have leapfrogged from Andamans to Amazon, so who knows?https://twitter.com/PaleoAutist/status/1081837917650206720 …
The 40,000 year Tianyuan skeleton from North China had the small Andamanese signal, later skeletons from Siberia c. 20,000 B.C did not. Most like possibly reconciliation is that people have been living in the Americas for much, much longer than previously thought.
