A history of the Crusades, as told by crusaders` DNA
(PHYSorg.com Archaeology & Fossils)

History can tell us a lot about the Crusades, the series of religious wars fought between 1095 and 1291, in which Christian invaders tried to claim the Near East. But the DNA of nine 13th century Crusaders buried in a pit in Lebanon shows that there`s more to learn about who the Crusaders were and their interactions with the populations they encountered. The work appears April 18 in The American Journal of Human Genetics.
