And the goal is to sample DNA from people all over the world, both indigenous populations and the general public.

Genetics, I think, resoundingly has answered the question of where we ultimately came from, we came out of Africa. And we came out quite recently, within the last 50 or 60 thousand years.

So it really is a synthetic effort to understand our common past.

But the question of how we migrated around the planet, how we populated the world, in effect, is still an open one.

We want everybody to have a chance to participate in this, because it is really the story of all of us, that's what we are trying to figure out.

With the Toubou we are hoping to find out who were the first people to settle in the Sahara.

His skin was probably not that dark, nor was he that muscular.

We believe that some of Adam's characteristics can still be seen in Southern Africa but we need to find out what they are.

IBM is helping to greatly advance and expedite quality sampling while providing our project investigators peace of mind that the information they are gathering is securely stored and protected.

The project is to focus on reconstructing how humans moved around the world, to tell of their migratory routes.

It was tough going. His world was in the grips of the last Ice Age. In Southern Africa it was drier than now, water was difficult to obtain and so were animals.

So what we can answer [as geneticists] is questions about biology, about biological ancestry. But to make any sense of that historically we have to contextualize it -- the archaeology, the linguistic pattern, even the climatology.
