Ancient Hominid Males Stayed Home While Females Roamed, Study Finds
Science Daily ^ | 06-001-2011 | Staff + University of Colorado at Boulder.

The males of two bipedal hominid species that roamed the South African savannah more than a million years ago were stay-at-home kind of guys when compared to the gadabout gals, says a new high-tech study led by the University of Colorado Boulder.

The team, which studied teeth from a group of extinct Australopithecus africanus and Paranthropus robustus individuals from two adjacent cave systems in South Africa, found more than half of the female teeth were from outside the local area, said CU-Boulder adjunct professor and lead study author Sandi Copeland. In contrast, only about 10 percent of the male hominid teeth were from elsewhere, suggesting they likely grew up and died in the same area.

"One of our goals was to try to find something out about early hominid landscape use," said Copeland, who also is affiliated with the Max Plank Institute for Evolutionary Anthropology in Leipzig, Germany. "Here we have the first direct glimpse of the geographic movements of early hominids, and it appears the females preferentially moved away from their residential groups."

A paper on the subject is being published in the June 2 issue of Nature.

The new study results were somewhat surprising, said Copeland. "We assumed more of the hominids would be from non-local areas since it is generally thought the evolution of bipedalism was due in part to allow individuals to range longer distances," she said. "Such small home ranges could imply that bipedalism evolved for other reasons."

Not just raiding and kidnapping - but also trading.

All primates species that form small bands (we are no exception) have all the juveniles of one sex or the other leave the home group and join a new group. Some suggest that teenage angst and alienation is a biological remnant of this behavior.

Among baboons it is the males.

Among chimps it is the females.

The point is that even a baboon ‘knows’ that you cannot keep reproducing within the same small group. One sex or the other has to be ‘swapped’ with another group.

Taboos against incest seem to be universal--it seems that all human societies know that too-close interbreeding is harmful. What this study suggests is that the pattern of the sons staying in the family abode while the daughters married out to another household was already found among these ancient hominids.

At a much more recent period, the Proto-Indo-European speakers seem to have had patriarchal families where the sons stayed put and the daughters married away--that is deduced from various words for family relationships in the later Indo-European languages.

Of course the marriage customs among the Paranthropi robusti would have differed in detail from later hominid species--they didn't throw rice since they didn't have rice.

It is truly stunning what passes for scientific analysis these days. You don't need empirical evidence at all; you only need a plausible explanation ... and a few of your buddies to go along with it.

They are so clueless. Walking on two legs is not a net advantage. Having two arms free to wield weapons is. Hunting does not cause our armpits to start lubricating for an extended fight, but the approach of a strange human does. Most human specific traits were and still are for tribal warfare.

Amazing what conclusions you can come to, as this article does, when you make some basic erroneous assumptions.

Usually, you can “prove” your assumptions by assuming your assumptions and examining the evidence through the lens of those assumptions... and NOT GET DIZZY DOING SO!

But of course...it was the Stone Age.

They had a little child throw the first one ("let him who is without sin cast the first stone...").
