Monkeys playing tig, as people

Gorillas play of tag, as well as the people to maintain their competitive advantage.

This is the first study that has shown that monkeys, like humans, touch to his friend, and then try to get away without giving touch to her. In this case, the one who touched the last one - has an advantage.

The study conducted a behavioral biologist Dr. Marina Ross of the University of Portsmouth, Edwin van Leuven from the University of Amsterdam and Dr. Elke Zimmermann of the University of Veterinary Medicine in Germany. An article about the study was published in the Journal of the Royal Society Biology Letters.

This is the first study on the response of animals to the unjust situation in the wild. Previous studies conducted in laboratories.

Dr. Ross said: "This study allows us to look at the monkeys with opportunistic point of view.

"Our observations of the game gorillas showed important similarities with the children’s game of catch. Gorillas prikosatsya not only to his comrades and then running away from them, but changed roles after touching them catching up."

Scientists can not conclusively determine whether all the gorillas play in the gear, but the ones for which were monitored, behave like humans.

Dr Davila Ross said that the game is in violation of the rules, apparently, is of great social importance, as it allows the monkeys, like humans, learn the boundaries of permissible conduct and verify their comrades, and even parents.

She said: "This is the first study to empirically demonstrating that monkeys use the game to detect the effects of unjust social situations."

The study also found that heavier touch, provoked a strong reaction, the more tender, which is often ignored.

Behavioral responses of apes in game situations is not distorted by force or by the rank of the opponents, as is common in more serious circumstances, such as the struggle for food.

Dr. Ross said that, apparently, the game allows the monkeys to develop behavioral patterns used in real conflicts, and playing the role of catch-up and catch-up developing more advanced ways of communication.

Dr. Ross is an expert in the field of primate behavior, with a focus on playing and laughing. Together with colleagues, she studied the video, which captured 21 playing gorilla of the six colonies located in five European zoos. This video, which captures the specific behavior of overtaking each other gorillas, filmed by Dr. Ross for three years.
