Big brains mean ‘tiny testes’

`Brainiacs and scholars everywhere may gnash their teeth, but according to a recent study of bats, nature forces the males of a species to make a painful trade-off between mental capacity and sperm production.

Because of the high-energy demands of both brains and sperm, scientists believe males cannot generate large amounts of both.

Bats were ideal subjects for the study. Some female bat species are unusually promiscuous, so natural selection led to males evolving enormous testicles in order to compete with more virile suitors – however at the expense of their brain capacity.’
