"All Native Americans descend from people that separated form northeast Asia about 25,000 years ago. They then mixed and evolved for about 7,000 years or so on the Beringia Plain. A small group then started moving south along the coast about 18,000 to 16,000 years ago. Some people moved the other way back into Asia. Around 13,000 years ago a way opened through the center of North America. Other people (Athabascans) came about 6,000 years ago. And most recently Inuit/Eskimo/Yupik people came from Siberia. There is a small contribution from people related to the Jomon cultures and Ainu in Japan and NE Siberia. There is a small contribution in places from Polynesians and perhaps from shipwrecked east Asians. But almost everyone in North or South America comes from those people that left the rest of Asia 25,000 years ago. However, that is a large amount of time. 10,000 years ago Europeans did not have light skin not could they digest milk as adults. Similarly, Native Americans changed a lot. The early people, although genetically direct ancestors had different skulls and skeletons than more modern Native peoples. Recent DNA studies just of the Mexican populations, have shown that for example the Seri people in NW Mexico are more distant from the Mayan people in SE Mexico than Europeans are from East Asians. Vast genetic diversity among Mexicans found in large-scale study Mexican Genetics Study Reveals Huge Variation in Ancestry More studies will undoubtedly show similar things throughout South and Central America.
Also, although there is thought to have been mainly one early group there are still differences in gene frequency. That group in the Beringia Plain was about 1/3 related to bones of poeple found in south central Siberia near Lake Baikal. These people are related to western Europeans. The rest comes from East Asian populations.

Here is the mtDNA (maternal) frequencies.
Here are some of the Y-DNA (paternal) maps:
This is C-M217 . This is most common in Athabaskans.
This is Q. The Q-M3 mutation likely evolved in east-Beringia, and in the Seward Peninsula or western Alaskan interior.
