One Common Ancestor Behind Blue Eyes
LiveScience: People with blue eyes have a single, common ancestor, according to new research. A team of scientists has tracked down a genetic mutation that leads to blue eyes. The mutation occurred between 6,000 and 10,000 years ago. Before then, there were no blue eyes. 'Originally, we all had brown eyes,' said Hans Eiberg from the Department of Cellular and Molecular Medicine at the University of Copenhagen.
