[size=150:2zpjsvbh]Female chimps can become killers[/size:2zpjsvbh]

Scientists in Scotland have discovered that female chimpanzees can be just as violent as their male counterparts.

The St Andrews University psychologists found examples of female chimps killing the offspring of incoming mothers, previously regarded as a male trait.

The Fife team has been studying chimps in the Budongo Forest, Uganda.

The researchers said only three previous instances of lethal aggression in wild female chimps had been documented in the past 50 years.

The belief was that male and females differed greatly in nature but the psychologists found that if the chimps' resources come under threat, the females could become just as aggressive as males.

While observing chimps in the Sonso community, the researchers came across three examples of female apes killing the offspring of incoming mothers.

One attack was so violent that a baby chimp's head was bitten off.

Simon Townsend, who led the study, said: "It's true that males are much more often seen to engage in extreme physical violence than females, and this has led to the notion of violent and demonic males in contrast to quite peaceful females.

"However, our research shows that, under the right socio-ecological circumstances, these chimp gender stereotypes collapse completely.

"If their resources are under threat, females can become just as violently aggressive as males."

Similar behaviour

Similar behaviour was described by a leading primatologist in the 1970s, but her findings were later disregarded as inconsistent.

Mr Townsend said female aggression only occurred under specific circumstances.

He added that an increase of immigrant females entering the Sonso community had put pressure on food and mate resources, which had caused the violence.

"It is impossible to predict when another instance may occur," Mr Townsend said.

"However, we are very interested in keeping a close eye on levels of female aggression in the Sonso community, especially in the instances when new females attempt to immigrate."

Vai kokonaiset n = 3.

Tämä varmasti kaataa jos jonkinlaisia paradigmoja aivan samoin kuin bonobojen penismiekkailu tai arvailut antiikin kreikkalaisten seksuaalijärjestelmästä tuolla naapurithreadissa.

Uskomattomia johtopäätöksiä. Käytännössä mikä tahansa eliö (sukupuolesta riippumatta) käyttäytyy aggressiivisesti resurssien ollessa uhattuna. Siitä sitten pitäisi vetää johtopäätöksiä naaraiden ja koiraden käyttäytymiseen.

Että olosuhteet vaikuttavat aggressioihin omia kohtaan, naaraillakin?

Näin ohimennen sanoen, tuota simpanssien käyttäytymisestä johdettua ja ihmisiin analogisoitua 'demonic males' -teesiä muuten kritisoidaan kovin sanoin teoksessa Man the Hunted (2005). Siitä voisi kirjoitella tännekin piakkoin...

Tässä kuitenkin mielestäni hauska arvostelu kirjasta:

The truth is, in countries not in social turmoil, human males are overwhelmingly peaceful. In the United States, for example, murder is rare, despite popular perception that it is not: FBI stats for 2000 say it's about 1.1% of all violent crime. By far the largest percentage of violence is assault at 63.9%--but most of us go through life never touched by it after our teenage years (if then). Most Western men don't beat their mates chimpanzee style. In the West daily human aggression means cutting another off on the freeway. Furthermore, violence seems to be a problem of youth--the commonest arrest age for murder is 18, the next is 19. Recidivism rates approach 80% in some instances; many of the same people commit crimes over-and-over, which skews and inflates stats even more. The chance of non-criminal males being violent decreases substantially with age and economic success. Wrangham is correct in asserting that men commit most violent crimes around the world. He never notes that most males never commit such a crime in their lives. Human males are NOT chimps nor are they demonic.
