Blond Hair Evolved Separately in Europe and South Pacific

Blond hair evolved separately in Europe and the South Pacific

Naturally blond hair is rare on Earth, limited mainly to northern Europe and the collection of South Pacific islands that includes the Solomon Islands. The researchers checked to see whether the C-to-T change on chromosome 9 was also present in Europeans. It wasn’t. That means blond hair evolved not once but twice. 

Nifty!
