Big brains mean 'tiny testicles'

WOMEN have suspected it for millennia, and scientists have finally proved it - men cannot have both big brains and big testicles.

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

my boyfriend is both extremely intelligent and has an unusually large head. uh-oh.

But what about his testicles? Are the unusually large as well?

[sugarimp]

Hey, I'm not the one who brought up the "unusually large head". This article is about testicles, afterall.

Agreed, I'd like to see a species specific study! Correlation does not necessarily imply causation!

i thought this was a funny spoof- surpised anyone would think it scientfic fact.

[robynchick]

No, it would be a seriously interesting study!
As anthropologists, we're probably aware of how much energy it takes to grow and maintain a large brain. To the extent that, our species is born relatively helpless.

I've wondered before if using so much energy to create a large brain would decrease the amount of energy spent on growing other essential tissues...

This is also a study done on flying creatures where there must be a weight trade off for flight. I agree with above lets see the study done on humans!

the study should be done with humans also

absolutely. thats why i posted this here-so that any anthropologists looking for some research ideas might get some :D

they do, although it has absolutely nothing to do with intelligence--Einstein had a very small brain, actually. But then again, testicle size has nothing to do with the size of anything else either.
