Der Titel dieses Threads ist m.E. äußerst unglücklich und falsch...
Aber neues zur Genetik der ca. 11,5 Ka alten Kinder - Bestattungen vom Upward Sun River, es muss wieder einmal alles "umgeschrieben" werden:
“This individual represents a previously unknown population, which is also the earliest known population of Native Americans,” says Eske Willerslev, an evolutionary geneticist and one of the authors of the new study. “We can address fundamental questions such as when people came into North America because this population is related to everyone else.”
Using demographic modeling, the researchers concluded that the founding population of Native Americans began splitting from their ancestors in East Asia around 36,000 years ago. By 25,000 years ago, they had made a complete split. By 20,000 years ago, another divergence had happened, this time between the Ancient Beringians and the rest of the Native Americans. And within the next 3,000 to 6,000 years, the Native Americans further divided into Northern and Southern groups.
The Upward Sun River girl, buried next to an even younger infant in a ceremonial grave with red ochre on both of them, is a member of what researchers are calling the Ancient Beringians. Prior to sequencing her genome, scientists had identified two main groups of Native Americans: Northern Native Americans and Southern Native Americans, who split off sometime after entering the continent. This infant child belongs to neither of those two groups. That means that, somewhere along the way, another split must have occurred to create this unique Ancient Beringian group.
