saying goes that men can only think with one head at a time. It seems that, for male bats anyways, this may be intrinsically true: big brained bats have smaller testes and big balled bats have smaller brains
. The proposed reasoning is that since both brains and balls take lots of energy to grow, evolution reacted to whether the females of a given species are monogamous or not, thus determining whether higher sperm production or better ... conversational skills ...
would increase the male's reproductive success. I find this bloody hilarious.
In humans, however, big headed babies seem to be at increased risk for brain cancer
. No word on how they will fill out their jockstraps later on. Also on the human side, the IOM has stated, to the shock of no one who has any brains at all, that the food industry is using TV ads to convince kids to overeat
, and that TV watching is associated with obesity. Duuuuhhh.
