Roots of Human Family Tree are Shallow
"It's a mathematical certainty that that person existed," said Steve Olson, whose 2002 book "Mapping Human History" traces the history of the species since its origins in Africa more than 100,000 years ago.

With the help of a statistician, a computer scientist and a supercomputer, Olson has calculated just how interconnected the human family tree is. You would have to go back in time only 2,000 to 5,000 years -- and probably on the low side of that range -- to find somebody who could count every person alive today as a descendant. |
I remember reading somewhere that a certain genome had been traced all the way back to a single women. This was done by looking at something handed down in all women to their daughters. I will have to refresh my memory and do some research.
