This is the result of a DNA study done by Professor Stephen Oppenheimer and funded by The Bradshaw Foundation. As you go on the journey, here are some things I would like you to make note of and I would appreciate your comments:
1. 135-115,000 years ago, notice that the first human excursion out of Africa failed/Died out.
2. 74,000 years ago Toba exploded and reduced the worldwide human population to 2-10,000. Note the (about) 10,000 year absence of humans in India, Pakistan and parts of SE Asia. Also, there are two populations of 'out of Africa' humans that are seperated from themselves for about 10,000 years.
3. 65,000 years ago, the two seperated 'out of Africa' populations were rejoined.
4. 25-22,000 years ago, humans made it to Meadowcroft in North America.
5. 22-19,000 The Last Glacial Maximum(LGM), the coldest period during the Ice Age. Notice that at least six groups of humans are seperated from themselves. It is my hunch that it was this period that Mongoloids and Caucasians were distinguished. The oldest (undisputed) Mongoloid skeleton ever found is 10,000 years old.
6. 10-8,000 years ago, agriculture begins in Mexico, China, the Amazon and Indonesia.
I will provide a link below for you to begin the journey.

Very interesting read on the human bottleneck and the Toba eruption can be found at http://www.andaman.org/book/app-r/ch5_bottleneck/textr5.htm.
Good post, thanks.
Bump for later. Fascinating, blam.
I was not able to get the references (pop-ups and lots of other things blocked), and will have to dig them out in other ways and then reconcile them with that I thought I knew. In any case, this is educational, immensely entertaining, and thought provoking. Might even be right; that would be even better.
If only more scientists/anthropologists could do this well the Luddites and other anti-science folks would really be on the run!
Thanks.
This subject is covered in (exhausting) detail in Oppenheimer's excellent book: Out Of Eden. I also read his book Eden In The East, another good one.
Oopsie. You have two scientists, you get three opinions.
Could you put me on your GGG ping list, thanks.
Take off the period at the end.

The rest of the article is also interesting.
To read later.
Appearantly there's lots of room for conjecture.
Here's another approach:
Interesting post. Thanks.
Good info, thanks.

Hopefully it works now.
Things are definately complicated. Check out this article.

Wow! Thanks for posting that, I am totally impressed! The technology of DNA, the research, the compilation... What a fanastic effort! The visual affect is so educational. I sent the link to all I know, I liked it so much.
