Blondes

(picture by Aerixis Prime at B3ta.)

I'm wondering whether this suggestive idea (that a new study strengthened) is correct; that blondeness evolved recently in Europe due to selective evolutionary pressure. Kind-of-like lactose tolerance, which is also fairly-new in human development, and not yet fully spread through the human population.

Blondeness is certainly a striking personal trait, but does it mean more kids who survive to produce their own kids (the acid test of evolution)?
