On the Bright Side, Being Ugly Is No Longer Anti-Darwin

At long last, science offers us an explanation for why we're not all models.

A group of researchers at Newcastle University published a paper in the journal Heredity, according to this BBC report, in which they demonstrate that genetic mutations vary how people's genomes handle DNA repair. That variation leads to differing levels of unrepaired damage and that, apparently, explains why not everyone is good-looking, even though basic Darwinism would suggest that eventually there should be only attractive people. (That argument, known as the "lek paradox," is one favored by critics of evolutionary theory, the article says.)
