In a new report from the Loango National Park in West Africa, researchers found that chimpanzees have the capability and understanding of not only making tools but also treating injuries of friends and family members. The study consisted of 45 chimpanzees and was conducted between 2019 to 2021. They observed 76 open wounds on 22 of the apes. In 19 different instances they observed a member of the family catching a flying insect, pressing it between their lips to make a salve and then pressing it into the wound. This action was repeated several times either to the injured chimp by themselves or to another member. The scientists are not sure what the little dark insect was, but they are sure that the chimps were not eating them. The results were published in “The Journal of Current Biology”.
