Among the monkeys, chimpanzees, known to be highly intelligent, are known to be selfish animals in their work related to food, which brings back ungrateful images.
But research has shown that chimpanzees can also thank and thank other chimpanzees that have helped them in the past.
Researchers at the Max Planck Institute in Leipzig conducted experiments on chimpanzees without first feeding them.
The chimpanzees themselves needed to get out of bondage, secure food, or help other chimpanzees.
After leaving the bondage, there are two choices. One is choosing food that is beneficial to the chimpanzee who has helped herself and herself, or the second is choosing food for herself only.
After the experiment, chimpanzees chose food for both themselves and the chimpanzees that helped them. Furthermore, the more chimpanzees that helped to get the food to help, the more generous the helping chimpanzees.
This study once again confirmed the results of previous research conducted by the Institute on game theory models of social co-operation. The chimpanzee is actually much more human than previously thought.
