Bottleneck dates back 600 to 800 years, genome analysis shows; researcher says among population everyone is a 30th cousin.

A new study concludes that all Ashkenazi Jews can trace their ancestry to a bottleneck of just 350 individuals, dating back to between 600 and 800 years ago.
The study, published in the Nature Communications journal Tuesday, was authored by Shai Carmi, a computer science professor at Columbia University, and more than 20 medical researchers from Yale, Columbia, Yeshiva Universitys Albert Einstein College of Medicine, Memorial Sloan-Kettering Cancer Center, Hebrew University of Jerusalem and other institutions.
Researchers analyzed the genomes of 128 Ashkenazi Jews and compared them to those of non-Jewish Europeans in order to determine which genetic markers are unique to Ashkenazi Jews. They found that the Ashkenazi Jews genetic similarities were so acute that one of the studys researchers, Columbia professor Itsik Peer, told the Live Science website that among Ashkenazi Jews, everyone is a 30th cousin.
The findings will enable researchers to catalog nearly all of the genetic variations from the founding population, the studys authors said. Such thorough genetic cataloging could help clinicians interpret individual genetic mutations, improve disease mapping and provide insight into the histories of Middle Eastern and European populations, the study said.

The Scars of Evolution:"The most remarkable aspect of Todaro's discovery emerged when he examined Homo Sapiens for the 'baboon marker'. It was not there... Todaro drew one firm conclusion. 'The ancestors of man did not develop in a geographical area where they would have been in contact with the baboon. I would argue that the data we are presenting imply a non-African origin of man millions of years ago.'"
