Testicles vs.IQ?
» Oddball
Nothing like a spot of zoology.
In many bat species, females are unusually promiscuous, so natural selection has led to males evolving enormous testicles — at the expense of their brains. Their genitals of some bats make up 8.5 per cent of their body mass.
I’ve known guys who like large testicles but I think eight percent would be a bit much.
Guy bats from monogamous species have bigger brains.
I don’t think there’s a moral here.
