Taken together, the findings fit what is called the Beringian Standstill hypothesis: Humans moved from Siberia onto the Bering Land Bridge linking Asia and North America about 25,000 years ago, the idea goes, but were stopped by enormous glaciers.

After several thousand years, as glaciers receded, modern humans were able to move south.

There’s a great deal of evidence for that kind of activity at older sites in other parts of the world, he noted. Mandel, a geoarchaeologist at the University of Kansas who was not involved in the study, found it hard to see how the rocks and bones could come together without the help of people. But other archaeologists said the bone fractures and rock scratches were unconvincing.“They present evidence that the broken stones and bones could have been broken by humans,” said Vance T.

Holliday, an archaeologist at the University of Arizona.

Genetic studies strongly support the idea that those people were the ancestors of living Native Americans, arriving in North America from Asia.
