Big Brain Means Small Testes, Finds Bat Study

Big Brain Means Small Testes, Finds Bat Study
(New Scientist)
The analysis of 334 species of bat found that in species where the females were promiscuous, the males had evolved larger testes but had relatively small brains. In species, where the females were monogamous, the situation was reversed. Male fidelity appeared to have no influence over testes or brain size.

So if nature intended these monstrous sack caddies why does the promiscuity so ANGER? A terrible design loop. Huge testicles make for more rage but they only result from behavior in the opposite sex which might likely induce rage. No wonder the Texas defense works: "Well, she needed killin', your Honor."

By the way, about time you posted again. Slacker.
