Why some are unattractive

British scientists say they think they've figured out why Darwin's theory of natural selection hasn't made every human good looking.

BBC News reports that Newcastle University researchers have discovered a natural mutation in genetic selection that explains why even if the most attractive men and women were selected by their future mates, the so-called "good genes" wouldn't become commonplace and everyone would be pretty or handsome.

The very act of people selecting each other through sexual attraction allows for greater diversity of DNA and genetic makeup, the lead researchers professor Marion Petrie and Dr Gilbert Roberts maintain.

"We find that sexual selection can promote genetic diversity despite expectations to the contrary," BBC News quotes Petrie as saying.

The findings are published in the latest edition of the journal Heredity. – (HealthDayNews)
