Born Gay

Postby Lance Kennedy » Fri Dec 22, 2017 4:45 am

Reference : New Scientist, 16 December 2017, page 8

Recent studies have uncovered two genes that are associated with a higher probability of being gay in men. Also an antibody mechanism that may explain why it is more common for men to be gay if they have older brothers (who will be straight).

This is not the full story, of course, and more prenatal and genetic influences may be discovered in future, and possibly even environmental influences. But at this point in time, it seems that the claim that someone is born homosexual has considerable scientific backing.

Strangely, that's, sort of, what the Kin Selection hypothesis predicted. The gay sibling gives his resources to the offspring of the straight sibling's children and passes down 25% of his own genes. It's just another counter-intuitive evolutionary strategy. :D

The flash of light you saw in the sky was not a UFO. Swamp gas from a weather balloon was trapped in a thermal pocket and reflected the light from Venus.
