Big Balls = Tiny Brain


Bad news for bats. It turns out that there is a tradeoff between sexual prowess and brain size. The bigger a bat's balls, the tinier its brain. But the real kicker is, this can all be blamed on the female bats (are we really surprised, gentlemen?) The problem appears to be that in some species of bats apparently the female bats are terribly promiscuous. So if the poor male bat wants his genes to be inherited by a new generation, he is forced to have lots of sex with lots of female bats. And to do that, he has to have really big balls. But in order to evolve those big balls, the male bat gives up brain size and thus intelligence. In other species of bats where the females are content to settle down into monogamous relationships, there is no such problem. Yes, the male bats have smaller testicles, but they also have much bigger brains. Well I suppose the question is, if you were a bat, which would you prefer: lots of sex but being dumb as a....well, I don't know, a bat maybe; or a whole lot less sex but being smart as a....well, a really smart bat? Maybe this isn't such a raw deal for the male bats after all.

I'd rather be a dumb bat (I think). Hmmmmm, then again....

In my vast experience (one visit to a Safari Park last summer) bats are very proud of their genitalia. One dirty little bugger kept rubbing his wedding tackle up and down the wire mesh of his cage. I think amongst the bat population he was Don Juan.
