... but probably smarter for it. Researchers "trying to find the molecular basis of being human", speculate that genetic deletions, including the loss of penile spines in humans, may have led to the expansion of specific regions of the human brain. www.nature.com/news/2011/110309/full/news.2011.148.html

You mean the one who is pouting about the loss of his penile spines?

I could swear blind they were there this morning. As they are most mornings.

Even reading it made me a little edgy. The first report I read on this states: The researchers believe the loss of these spines in humans may be related to changes in human courtship. The loss of spines, they say, would result in less sensitivity and longer copulation, and may be associated with stronger pair-bonding in humans and greater paternal care for human offspring.Eh? Those are high-minded researchers. The other immediate thought could be how it might lead to recreational promiscuity.

That was the first thing I thought of too.
The thought of great spikes sticking out of it must have been a little off-putting for the ladies...

I've read this. Apparently some believe the loss of a penis bone helps keep the less fit males from breeding as impotence correlates to decreased overall health, thus improving selection for vigor.

Those things sound dangerous. The loss of them certainly increased life expectency.

eeeeh....the things our female ancestors had to put up with.... (if you'll pardon the expression...) unless of course they had hooks and teeth in their whoopsie-daisies...just to even things up a bit...

Males cats have that exactly. That is what causes the horrible yowling when the sperm device is pulled out. The hooks and spikes are supposed to be useful for detaching the ova, but the female cat is not always happy about it.

But Cheery, that would have meant that Velcro would have been invented much, much earlier, preventing essential struggling and learning experiences for mankind.

Kerouac - I don't doubt your scientific explanation but it makes me wonder why my Sebastian (nuted male) caterwauls furiously when facing another male cat and they are about to engage in a fur fight of note!
