Female chimpanzees use sticks as "dolls"

Apparently all girls are programmed to play with dolls...  even chimpsA new study featured in the Current Biology journal indicates that just like male and female humans, chimpanzees play differently depending on what sex they are.

While boy chimps tended to use sticks as toy weapons, girl chimps tended to carry them around as dolls instead.

"This is the first evidence of an animal species in the wild in which object play differs between males and females," said Richard Wrangham of Harvard University.

During a fourteen year observation of the Kanyawara chimpanzee community in Kibale National Park, Uganda, scientists discovered that chimpanzees primarily used sticks in four different ways; to probe holes that potentially contained honey or water; as props in displays or as weapons; during solitary or social play; and in a behavior that the study terms as 'stick-carrying'.

Stick-carrying consisted of holding or cradling detached sticks.  Although both male and female chimpanzees play with sticks, females play with them more often and they occasionally treat them like mother chimpanzees caring for their infants, the study reports. 

"We thought that if the sticks are being treated like dolls, females would carry sticks more than males do and should stop carrying sticks when they have their own babies," Wrangham said. "We now know that both of these points are correct."

While the study concludes that the young chimps learned their play habits socially from each other, the findings suggests that the tendency for girls to play more with dolls than boys do is a "biological predilection" and not just a result of sex-stereotyped socialization.

This study sounds like another one of those worthless stimulus projects.

I wonder if its the same ones they used to find out the effects of cocaine in chimps.

Hard to see how a 14 year study could have been funded by the 2009 stimulus package, but I'll take your word for it.

rofl; I love how everything is now political. The first thing anyone should be realizing about any issue, is that stupid beings will follow either the loudest, or the one who warns of impending danger. If you cross define that with the current status of the world as well as the human race you will see many things. The largest being things that politicians figured out years ago, and have now honed into an exact science. This is why morons come in here spouting about stimulus. One thing to keep in mind about that specific issue is that Obama did not create stimulus.

I will also add that though I use Obama as an example here it is not because I agree with him. I am just stating the obvious truth. As far as my political leanings, I personally abhor (that's hate in fancy English)all politicians primarily, but specifically Democrats and Republicans.

As for this study it seems to be a very primary as well as simple thing here which needed no study at all. A female of any being type is a mother biologically. They behave differently specifically as to the breed of animal. Humanoid creatures are a "TYPE" of primate when looked at very, very loosely, that has evolved to a much higher degree. The only thing that this may at the widest scope of vision affect is the primitive brain, and not even so much that in our specific species that is as evolved as the human race.

This at best is like watching a kindergarten class and predicting who will be a doctor, scientist, lawyer, engineer, or technician by the toys they play with. That at best would be an absolute failure as is this whole big wad of nothing!

No, I don't think that was the point at all. The findings of the study showed that the different genders behaved differently when using sticks. Using your analogy, it would be more like observing female children playing with dolls and male children played with toy guns. The behaviour would not be caused by external influences, but by biological differences between males and females. In the study, careful attention would have been made on the influence that the parents and older groups had on the youth's activities.

While it is interesting that young chimps display differences in behavior depending on sex it is a leap to say that the difference is biologically driven since there was no control on socialization. This is not to say that I don't believe that biological differences influence behavior. Just that nothing in the article seems to offer proof of this.

Yeah, it's gonna be difficult to isolate the effect of socialization. You'd have to have them grow in a controlled environment. No, I don't mean a circus!
