[A study in the journal Evolution and Human Behavior] argues that blond hair originated in [Europe] because of food shortages 10,000-11,000 years ago. Until then, humans had the dark brown hair and dark eyes that still dominate in the rest of the world. Almost the only sustenance in northern Europe came from roaming herds of mammoths, reindeer, bison and horses. Finding them required long, arduous hunting trips in which numerous males died, leading to a high ratio of surviving women to men.
Lighter hair colours, which started as rare mutations, became popular for breeding and numbers increased dramatically, according to the research, published under the aegis of the University of St Andrews.
“Human hair and eye colour are unusually diverse in northern and eastern Europe (and their) origin over a short span of evolutionary time indicates some kind of selection,” says the study by Peter Frost, a Canadian anthropologist. Frost adds that the high death rate among male hunters “increased the pressures of sexual selection on early European women, one possible outcome being an unusual complex of colour traits.”
Blonde prehistoric cavegirls. Mmmmm. But what does the future hold?
A study by the World Health Organisation found that natural blonds are likely to be extinct within 200 years because there are too few people carrying the blond gene. According to the WHO study, the last natural blond is likely to be born in Finland during 2202.
A world without blonde jokes. I think the living will envy the dead.
[UPDATE (Jan 25 / 2013): Turns out the study claiming that blondness gene would disappear within 200 years was a hoax. –The Foreigner]
