Question

the first people to live in america who crossed into alaska

Answer 1

The theory was that the first Americans were Asians who crossed from Siberia to Alaska. No one fully knows. There is now a theory floating around that they may not have been the first. Examinations of skulls found in the eastern US do not appear to be from the same people we imagine crossing the 'land bridge'. They were more like those found in Europe, yet not enough to be sure, and may be from an as-yet unknown group of people altogether.
