First Americans arrived recently, settled Pacific coast, DNA study says
A study of the oldest known sample of human DNA in the Americas suggests that humans arrived in the New World relatively recently, around 15,000 years ago.
The DNA was extracted from a 10,300-year-old tooth found in a cave on Prince of Wales Island off southern Alaska in 1996.
The sample represents a previously unknown lineage for the people who first arrived in the Americas.
The findings, published last week in the American Journal of Physical Anthropology, shed light on how the descendants of the Alaskan caveman might have spread.
