Penis spines?
Well. Looks like our primitive friends know more than we give them credit for.
Who has the penis spine ping list? Or did we lose that too?
lmao...
Good one Larry!!
We're hydraulic.
"The evolutionary biologist Richard Dawkins speculated in 2006 that the loss of the bone in humans, when it is present in our nearest related species the chimpanzee, is a result of sexual selection by females looking for signs of good health in prospective mates. The reliance of the human penis solely on hydraulic means to achieve a rigid state makes it particularly vulnerable to blood pressure variation. Poor erectile function betrays not only physical states such as diabetes and neurological disorders but mental states such as stress and depression.[6]
It has also been speculated that the loss of the bone in humans, when it is present in our nearest related species the chimpanzee, is because humans evolved a mating system in which the male tended to accompany a particular female all the time to attempt to ensure paternity of her children which allows for frequent matings of short duration.
Observation suggests that primates with a baculum only infrequently encounter females, but engage in longer periods of copulation which the baculum makes possible, thereby maximizing their chances of fathering the female's offspring. For humans, it is almost impossible to tell when the female is fertile so frequent matings would be necessary to ensure paternity."
I have the list!
(It’s composed of nothing but zotted bloggers.)
I think Eaker has it but the Mom won’t let him take it out of the house by himself.......:o)
I took the word “spine” as in “backbone”.
You think *you* guys were saying “WTF?!?!”.....
