The Osaka University research group has confirmed through experiments that two Japanese monkeys can act in cooperation with each other to obtain food, and is attracting attention as a new aspect of Japanese monkeys.
According to the research group of the Graduate School of Human Sciences at Osaka University, which has been conducting experiments, Japanese monkeys act in cooperation with other monkeys because they have a strict vertical relationship within the herd and attack the surroundings violently around food. It has been thought that there is nothing.
However, in the group of Awaji Island in Hyogo Prefecture, which is relatively close to the group of Japanese monkeys, another monkey comes when an experiment is conducted using a device that can acquire food when two monkeys pull the rope simultaneously. The percentage of the two who were able to obtain food in cooperation, such as waiting for, was 58.7% of the 1500 experiments.
On the other hand, when the same experiment was conducted with a herd of Japanese monkeys in Maniwa City, Okayama Prefecture, only 1% of the 200 experiments were able to cooperate.
According to the research team, Japanese macaque research has been conducted in various places for more than 70 years, but it is the first time that it has been confirmed that they will feed together.
“I was very surprised when the monkeys cooperated and took food. I want to investigate further why monkeys in the Awaji Island herd can cooperate.”
