Why Men Don't Have Sensory Whiskers and Spiny Genitals

Posted by samzenpus on Thursday March 10, 2011 @06:34AM from the we'd-need-different-pants dept.

sciencehabit writes "Most male mammals wield a penis covered with spines made of keratin, the same material that forms fingernails, to sweep out competitors' sperm and irritate a female into ovulating. Even chimpanzees, our closest relatives, have penile spines. So why don't men? A new study suggests that this feature disappeared due to a chunk of DNA that went missing after our evolutionary divergence from chimps. The researchers have identified another DNA deletion that may have contributed to humans' bigger brains."

Because I'm good at irritating females, yet somehow it doesn't lead to their ovulating.

I'd better go see a doctor.
Or a veterinarian.

What, you mean these spines on my penis aren't normal?

I'd better go see a doctor.
I think it means you should stop shagging hedgehogs.
