People first arrived in the Americas at least 12,000 years ago. The timing of their arrival and the route by which they travelled are not known. Did they follow an inland ice-free corridor route from Siberia to the unglaciated regions south of the ice sheets? Or did they take a coastal route, travelling by boat down the Pacific Coast? Did people arrive during the ice age, or not until after the glaciers receded?
This site explores these and other questions, and looks at some of the evidence and ideas that have been proposed to resolve them.
