Science wants $20 before I can read the full article. Perhaps I will remember to look at it at the library.

Anyway Popular Archaeology has a nice write-up, http://popular-archaeology.com/issue/12012013/article/before-they-were-native-americans-they-were-beringians 

When one accepts that God didn’t actually say the earth was created just 6,000 years ago, and God doesn’t lie to us in nature, then one can propose good working theories that help explain the awesome diversity we see around us and within ourselves.

Starting around 25,000 years ago, our North American forebears found a fortuitous “green” zone in the Bering Straight, which was then well above sea level, and the area supported short shrubs. The key here is that wood is indispensable in the cold. They used the brush to ignite large bones (with marrow and fat within that would burn and keep the fire going).

This warm zone, that would have been the result of some particular arrangement of ocean currents and weather patterns (and probably the geography), allowed these ancients a workable place to live, but it was also isolated. They didn’t mingle with their progenitors in the rest of Siberia.

Thus, the native Americans  have approximately 10,000 extra years of divergence from those Siberians than we can explain if they just came over the Bering land bridge 15,000 years ago when the ice finally started retreating in our current geological climate epic. (Global warming is good stuff, huh!)

See, this makes good sense, and it gives us a good working understanding of why things are the way we find them today. Read the rest of this entry »
