There's a lot of debate in the field of anthropology about how humans spread across the globe. But a new study suggests that case (or at least a part of it)
Using ancient and modern genomic data, a team of researchers found that the ancestors of all present day Native Americans entered the Americas in a single migration. The findings, which were published in the journal Science last month, indicate that migration occurred some time between 13,000 and 23,000 years ago.
This research has big implications for the Pacific Northwest. According to anthropologist Loren Davis, significant findings may lie offshore, along Oregon's "lost coast" — an ancient coastline submerged at the end of the last glacial period. That coast, says Davis, is the route early humans would have travelled to enter the Americas.
