Let me get this straight. The men would lay around the house and the women come and go....

And this guy thought he could improve on the situation.

Our Male Ancestors Stayed Close to Home, While Females Wandered About

At the outset, the researchers wanted to learn something about how ancient hominids used their landscape — that is, whether they covered far distances, or stayed closer to home. The goal was to discover whether their travel habits contributed to their becoming bipedal, since moving on two legs is far more efficient and takes less energy than using all fours.

But, as is often the case with science, they found something unexpected, a novel insight into the social behavior of our earliest human ancestors. It turns out that the males of two bipedal hominid species that roamed the South African savannah more than a million years ago were the stay-at-home types, compared to the wandering females, who went off on their own, leaving the men behind....

..."Our results don't necessarily imply that females were strong-willed and struck off on their own upon adulthood in search of new mates, but that is, indeed, still a possibility," she said. "In most primates, females don't transfer and males do. But, in the few species in which females are the ones to leave, they generally do so under circumstances in which their home primate group comes into contact with another community."

Rather than the females being completely on their own — and becoming likely targets for predators — they typically transfer directly into a new group, according to Copeland: "The females appear to have been the ones to leave the community to find new mates, while males did not leave, but this pattern is also found in modern chimpanzees, our closest relatives."

"In chimpanzees, the pattern does not result from female power so much as a reaction to male power, in which the males choose to stay at home and defend their territory with their male kin," she said. "Females are indirectly forced to leave the community to find unrelated males as mates."

Chimpanzee females are independent and, although part of a "community," often will travel by themselves with their offspring within the community's territory, Copeland said.

"The pattern we found in the hominids for female — but not male — dispersal actually suggests…[that] perhaps hominid females were fairly independent, like chimpanzee females," she said. "In that case, maybe they did literally strike out and venture into new territories looking for mates. It's also possible that the community was more tight-knit, and that females transferred directly into other groups as part of big community meetings."...

So it is as I suspected. A guy could sit on his ass, the women come to him (probably with a beer), they we'd change the ladies regularly.

And the problem was? How stupid were they? We had it made.
