Chimpanzees were significantly more likely to voluntarily place resources at the disposal of a partner, and thus to choose a risky but potentially high-payoff option, when they interacted with a friend as compared to a non-friend.Īltruism or selflessness is the principle or practice of concern for the welfare of others, even at a risk or cost to ourselves. The results showed much greater trust between friends than non-friends. In other words, the trust rope offered the potential for a win-win, but only if chimp one trusted chimp two enough to send something back.Įach chimp played the game 12 times with his or her friend and another 12 times with his or her non-friend. When the trust rope was pulled, the other chimp got immediate access to a much more tempting food item and the option to send a treat back to the first chimp (or not). In the game, chimps had a choice between pulling a "no-trust rope" and a "trust rope." When the no-trust rope was pulled, the first chimp got immediate access to a food that he or she didn't like especially well. They then asked the chimps to play a trust game, both with their friend and with their non-friend. Based on friendly interactions among chimp pairs, they identified each chimpanzee's closest "friend" and a "non-friend. Researchers tested trust by observing the interactions of 15 chimpanzees living at Sweetwaters Chimpanzee Sanctuary. Trust is demonstrated in chimpanzee friendships. We trust friends with crucial resources or important secrets, and chimpanzees show a comparable pattern and extend trust selectively toward those individuals they are closely bonded with. Trust is a defining element of genuine friendship. Develop friendships with those that they can trust The meat is much prized and its subsequent sharing strengthens male alliances and familial bonds. For example, Ivory Coast chimpanzees hunt cooperatively to catch red colobus monkeys, coordinating their actions to increase their chances of success. ![]() Older chimpanzees generally prefer spending more time with, and grooming, chimps they have developed mutual friendships with over the years, understanding each other and how their close friends are feeling.īonded individuals demonstrate complex cooperation, not just helping each other out but using coordination and an understanding of partnership to achieve shared goals. Each individual chimpanzee develops personal relationships with others in their group which last a lifetime. ![]() Complex social livesĬhimpanzees live in social communities ranging from 20 to 150 individuals, with subgroups of individuals within the community. Chimps can even outsmart humans on some memory tasks. ![]() They have individual personalities, communicate via an extensive array of facial expressions and vocalisations, make and use tools, and experience a range of complex emotions such as empathy and grief. Chimpanzees are our closest living relatives, sharing more than 98 percent of our genetic blueprint, and just like us, they live in complex social societies.
