New Research on the First Americans Coastal Route Idea

Researchers analyzing boulders and bedrocks on Alaskan islands found that a coastal migration route was accessible to humans from Asia entering the New World 17,000 years ago. Ancient seal bones in the area of research have been dated to 17,000 years ago. This shows food was available in the area of glacier retreat 17,000 years ago. Four islands were studied 200 miles south of Juneau. Researchers took rocks from that area to determine how long the islands studied had been free of ice. They used a technique called surface exposure dating, which shows the time when the rocks began accumulating chemicals that appear as the ice melts. The date for this chemical change on the rocks was at 17,000 years ago.

The evidence at Monte Verde in Chile has proven humans were living there 15,000 years ago. The same is proven for the Paisley Cave site in Oregon. The coastal route for the First Americans would have been a far easier route to enter areas south of Canada than the treacherous route humans would have to take overland. And that area lacked the resources for human survival long after 15,000 years ago.

The research is published in. The May 30 journal Science Advances.
