Genghis Khan 'descendant' not so sure after all

A United States accountancy professor said to be the first man outside Asia identified as being directly descended from Genghis Khan says he does not believe the warlord is his ancestor after all.

Last month Oxford Ancestors, a British company which offers genetic tests to people trying to trace their family trees, said DNA results showed Tom Robinson shared key chromosome markers with the 13th-century Mongol leader and was therefore a likely descendent.
