‘Iceman’ Had Brown Eyes and Hair, and Was Lactose Intolerant - NYTimes.com

‘Iceman’ Had Brown Eyes and Hair, and Was Lactose Intolerant - NYTimes.com: The lactose intolerance makes sense, said Albert Zink, an anthropologist at the European Academy of Research in Bolzano, Italy, who was one of the study’s authors.

“In early times, there was no need to digest milk as an adult because there were no domesticated animals,” Dr. Zink said. “This genetic change took hundreds of years to occur.”

But the scientists were surprised to find that �tzi had a strong predisposition to heart disease. “If he wasn’t shot with an arrow, it would have been possible that he might have had a heart attack soon after,” Dr. Zink said.
