Studies of rats suggest that rape becomes common in rodent communities only as normal social mores break down under pressures such as overcrowding. Young bull elephants tend to become rogues only when the herd has lost the presence or authority of older bulls, who would normally keep the lads in line. So even with animals further down the evolutionary tree than man, social factors play a part in an individual's aggressive behavior. Evolutionists such as Thornhill and Palmer fail to take social factors into account. They're so mired in biological determinism that they interpret all findings in light of that one theory.
Evolutionists also pay no mind to the mind.
But human consciousness makes for a difference between blokes and scorpion flies that will always leave men culpable for rape, no matter what geneticists might one day find under the microscope. Our legal systems are based on the understanding that this ability to think makes us responsible for our actions, no matter what our animal instincts dictate. Perhaps evolution has left maleness associated with rape impulses. While that would be sad for both sexes, it doesn't seem like news. But neither is it news that humans can analyse their impulses and choose which ones to act on.
