Cavewoman Blondes Had More Fun Too
According to scientists at the University of St. Andrews, blondes have been having more fun since the end of the last Ice Age.
A report, published in Evolution and Human Behavior, says women in north European evolved blond hair and blue eyes to stand out from their rivals at a time when males were scarce and competition was fierce.
It appears that blond hair originated in the region because of food sortages 10,00-11,000 years ago. Many men died in long, hard hunting trips for food, leading to a much greater ration of women to men. Lighter hair colors became popular for breeding, allowing the rare mutation to continue.
Analysis of north European genes, carried out at Japanese universities, has isolated the date of the mutation to about 11,000 years ago.
The World Health Organization says natural blondes likely will be extinct within 200 years because there are too few people carrying the blond gene.
