Cavemen prefer blonds

Thanks to a food shortage and a man shortage about 10,000 years ago, men were in such demand they had their pick of mates. With so much competition among women to find a mate, nature and evolution kicked in to give some cave women a distinctive look to attract the opposite sex: blond hair and blue eyes.

So says a new study published in the British science journal Evolution and Human Behavior.

This is nonsense, of course...

It has more to do with Ricketts than with "nature" deciding for women to look attractive....

Nature doesn't make such decisions (Unless they are implying intelligent design instead of evolution).

But a woman who is blond tends to have pale skin that will absorb more sunlight, and therefore more vitamin D, and will not develop rickets. Ricketts causes bone deformities (bow legs, deformed pelvises)...and not only are women with ricketts less attractive, but if you have a deformed pelvis, you have a good chance of dying in childbirth. So blonds will be healthier, have more kids, and voila, genetic drift into blondness...

There are exceptions: But usually these populations have an alternative source for vitamin D...

On the other hand, if you are an Albino in Africa you will be disadvantaged...

When I was in Africa, we had an Albino who had a beautiful baby...but she was ugly and wrinkled and we had treated her for severe sunburns and skin cancer...so I asked: Who would marry her...

And I was told: A blind man. There was a blind man who was blinded on the job and had a pension...so the families arranged the marriage with this albino woman...

They both seemed happy with the bargain...
