LOL!
No comment necessary!MALES that boast the largest testicles also have the smallest brains, a study of bats has revealed.
Although not quite proof of the charge that men tend to think with their genitals, the discovery offers the first firm evidence that males make an evolutionary trade-off between intelligence and sexual prowess.
The large amounts of energy needed to support large testicles that pump out vast quantities of sperm, and big brains that support a more advanced intellect, mean that male bats struggle to do both, the findings suggest.
So in species where females are promiscuous — creating an evolutionary advantage for large testes and lots of sperm — the males tend to grow big testicles at the expense of smaller brains.
