Some hunter-gatherers turned their backs on America again – time

Modern humans came to the Americas from the North, at least according to a theory well supported by archaeological finds and DNA analysis. According to the theory, the first settlers came to the new home continent from the north along the gradually ice-free coasts of the Beringia land bridge towards the end of the last glacial period. What the immigration routes might have looked like and when the first settlers ventured as far as America is still a great mystery. It is also disputed where exactly people originally came from in Asia.
