Monkeys love to work in a team

It is known that chimpanzees sometimes combined to deal with any problems. However, scientists were not sure whether they intentionally cooperate to achieve a common goal, or is it by chance, when a few individuals just focus on the one task. Recent studies show that chimpanzees form teams deliberately.

Researcher Alicia Melis devoted several years studying chimpanzees and cooperation in their society. Studies carried out a series of experiments to study the mechanism of cooperation monkey.

12 chimpanzees were divided into pairs. Each team received a box, inside of which was a tasty reward in the form of a grape, but it was hard to get. Each box is equipped with a special mechanism for the issuance of grapes, and to use it, you must use both the two are not interchangeable tools. One chimpanzee have to pull bunches of the hole using a small rake and the other chimpanzees, in turn, should push to partner these clusters of special wand, as they lie beyond the narrow bars with his hand, and push them might as well get it - no. What is important is that the one who has to pull, push could not because I was in a cage in front of the box and work around it was not able to. The same applies to the second chimpanzee. Thus, the monkeys had to help each other cope with the task.

Setting complicated by the fact that both instruments are initially given only one chimpanzee. Thus, to even begin to address the problem, he had to share with a partner tool. Solved by 10 of the 12 chimpanzees and exchange took 97% of the time from the process. Three-quarters of the time, "leading" the chimp was thinking what he should give tools to the partner.

The results indicate that chimpanzees can develop a strategy to address and interact with each other in the same way as humans do, and can assign roles to succeed.
