this question came up when i was driving around doing errands and remembered a quote a heard once. "the only thing that 'separates' humans and the rest of the animal kingdom is porn."

it makes sense, if monkeys could get more sexual arousal from the sight of a female rather than pheromones they'd look at porn too. i mean they masturbate, dogs hump people's legs (even though this is generally a dominance assertion thing they don't assert squat more often then not), i was at the zoo in kindergarten when a porcupine humped a log. they fight too, interact in non-sexual social manners, they eat, and sleep aswell.

so, are really humans any different than humans (given that humans are descended from one animal or another), why or why not?
