DNA/African origins of humanity

The National Geographic, March 2006 issue has an article entitled, The Greatest Journey Every Told”. It discusses genetic evidence on the origins of mankind out of Africa and his subsequent migration. Although this is what Diop, Williams etc, etc have noted many times over, I still think it’s a good read.

Excerpts:
Everybody loves a good story, and when it's finished, this will be the greatest one ever told. It begins in Africa with a group of hunter-gatherers, perhaps just a few hundred strong. It ends some 200,000 years later with their six and a half billion descendants spread across the Earth, living in peace or at war, believing in a thousand different deities or none at all, their faces aglow in the light of campfires and computer screens.

In between is a sprawling saga of survival, movement, isolation, and conquest, most of it unfolding in the silence of prehistory. Who were those first modern people in Africa? What compelled a band of their descendants to leave their home continent as little as 50,000 years ago and expand into Eurasia? What routes did they take? Did they interbreed with earlier members of the human family along the way? When and how did humans first reach the Americas?

The article also discussed this:

…probably between 50,000 and 70,000 years ago-0ne small wavelet from Africa lapped up unto the shores of Western Asia. All non-Africans share markers carried by those first emigrants who may have numbered just a thousand people."

Interesting point! Also my question is,what made these groups migrate...the exploratory nature of man?

I have a link to National Geographic, but that only gives an excerpt. You would have to get the magazine for full article. It’s a good read.

Exploratory nature, or following herd migrations, etc. There were actually earlier migrations out as well. We just have no survivors.
