In museums around the world, reproductions of Neandertals sport
striking blue or green eyes, pale skin, and gingery hair. Now new DNA
analysis suggests that two of the most closely studied Neandertals—a
pair of females from Croatia—were actually brown-eyed girls, with
brunette tresses and tawny skin to match. The results could help shed
new light on the evolution of the family that includes both modern
humans and Neandertals, who died out some 30,000 years ago.
The study has provoked deep skepticism among several outside
researchers, however, who criticize numerous aspects of its methodology.
The results also run contrary to other genetic evidence and to a
long-held hypothesis that Neandertals, who lived mostly in northern
latitudes, must've had light skin to get enough vitamin D.
But even scientists who have doubts about the new research say it
still provides food for thought. "Neandertals occupied a wide
geographical range," says John Hawks of the University of Wisconsin,
Madison, who was not involved in the study and who is also studying the
physical traits of ancient humans, so "it's likely that they were
variable in pigmentation. ... We are really at the first step."
