From Science Daily: A statistical approach to studying genetic variation promises to shed new light on the history of human migration..

Scientists from the University of Oxford and University College Cork have developed a technique that analyses shared parts of chromosomes across the entire human genome. It can give much finer detail than other methods and makes it possible to delve further back in time and identify smaller genetic contributions.

Application of the method has already turned up such surprising findings as a strong Mongolian contribution to the genes of the Native American Pima people and gene flow from the north of Europe to Eastern Siberia. [continue]
