“This is also the reason you don’t have any very close connection between contemporary Siberians and Native Americans.” “The vast majority of the genetic makeup of present day Siberians comes from this last push,” said Willerslev. They Ancient Paleo Siberians were themselves supplanted by another band of East Asians heading north about 10,000 years ago that gave rise to a group dubbed the “Neo-Siberians”. The team add that one possibility is that the mixing involving the East Asians occurred in southern Beringia – one of the areas that could have offered respite from harshening conditions at the time. “This is the first evidence we have, real evidence, of something very close genetically to Native Americans,” he said. “ Native Americans are not the first people in north-eastern Siberia as most people, if not everybody thought,” said Willerslev, adding that DNA recovered in north-eastern Siberia from what is believed to be an Ancient Paleo Siberian was crucial to the work. The East Asians also mixed with other descendants of Ancient Northern Siberians to give rise to another group, who the team dub the Ancient Paleo Siberians, who went on to supplant the existing group. Instead, analysis of the collection of genomes suggests the population that became the ancestors of native North Americans was the result of liaisons about 20,000 years ago between East Asians, who travelled north, and a group distantly related to the Ancient Northern Siberians. “They were living as big game hunters of woolly mammoth and woolly rhinoceros,” said Willerslev.īut, crucially, this population does not appear to be the direct ancestor of Native Americans. The researchers say they split off from the former 38,000 years ago – in other words, very shortly after Western Eurasians and East Asians themselves became genetically distinct. The results reveal these individuals were part of a previously unknown yet widespread group, dubbed the Ancient North Siberians by the team, who were genetically distinct from both Western Eurasians and East Asians. ![]() ![]() “What we see here is a much more complex story than what we believed was the case,” said Willerslev, director of the Lundbeck Foundation Centre for Geogenetics at the University of Copenhagen. While it had previously been thought that these remains might be from the ancestors of native North Americans, the DNA data suggests otherwise.
