Why, then, have chimps not evolved this social structure? The answer may lie in the history of the habitats they occupy. Both species of primates live in tropical forests along the Zaire River -- chimps north of the river, bonobos to the south. Their environments seem to be quite similar today. But about 2.5 million years ago, there seems to have been a lengthy drought in southern Zaire that wiped out the preferred food plants of gorillas and sent the primates packing. After the drought ended, the forests returned, but the gorillas did not.
Chimpanzees in this environment south of the river had the forest to themselves, and could exploit the fiber foods that had previously been eaten by gorillas -- foods that are still eaten by gorillas to the north. With this additional food to tide them over between fruit trees, they could travel in larger, more stable parties, and form strong social bonds. They became bonobos.
On the north side of the river, the chimps had to share their niche with gorillas, which eat the fiber foods. The chimps have to compete for fruit, and occasionally meat, food resources that tend to be widely scattered. Female chimps disperse into the forest with their infants to find enough to eat, and cannot spend time together to forge strong bonds. The changes in social behavior that occurred in response to this environmental factor may be what led chimps down a different evolutionary path, toward a society more prone to violence.

Alltså miljön! ändrade de sociala förhållandena för bonobos.
Fömodligen precis på samma sätt som jordbukskulturen gav nya premisser för människan.
Huruvida detta syns i gener eller fortsatt är ett socialt inlärt beteendemönster lämnar jag dock till experter finna ut. och sorry men du är alltså inte en sådan.

Precis, men varför tror du gener ändras? Olika miljöer ledde till olika selektiva tryck som i sin tur ledde till olika genförändringar hos de två arterna eftersom de var genetiskt isolerade från varandra. Bla ledde genförändringar till att bonobohanar började producera mindre testosteron. Hur tror du evolution fungerar?
Och som jag redan förklarat, människor i jägar och samlarsamhällen lever inte som bonobos. Mordfrekvensen är oändligt mycket högre än i våra industriella samhällen.
