NEW YORK (AP) -- Scientists have pieced together most of the DNA of a man who lived in Greenland about 4,000 years ago.
They know a little bit about what he looked like -- and more.
An analysis of the DNA suggests that the man probably had brown eyes, and darker skin than most Europeans.
He also had type A-positive blood -- and an increased chance of going bald.
And, he had several biological adaptations for surviving in a cold climate.
It's the first genome from an ancient human. And it shows the potential for what one expert calls a time machine for learning about the biology of people from thousands of years ago.
The research appears in the journal Nature.
