BARCELONA, Spain, Jan. 27 (UPI) -- Ancient Eurpoeans were dark-skinned, had blue eyes and may have been lactose intolerant and unable to digest starch, according to a genetic analysis of 7000-year-old skeletons.
The two skeletons, called La Brana 1 and 2, were discovered in a cave system in northwest Spain in 2006. Scientists at Institute of Evolutionary Biology extracted genetic material from the tooth of La Brana 1, who was well preserved in the cool, dark conditions of the cave system.
