Chimpanzees can help each other when injured. Scientists have found that chimpanzees not only treat their own wounds (1) they also provide ‘first aid’ to others. This discovery suggests that chimps may recognise (2) another chimp is hurt and try to help. A team of researchers came to this conclusion after reviewing years of previous studies (3) observing two groups of chimpanzees for months.
The researchers documented numerous cases where chimpanzees cared (4) their own injuries. Common behaviours included licking wounds and chewing plants to apply the material directly to open wounds. These methods can help remove dirt and prevent infections (5) chimp saliva and some plants contain healing chemicals.
Even (6) remarkable were seven examples of chimps helping others. For instance, a young male chimp was seen licking a wound on another chimp’s leg, and in one case, a male helped a female escape (7) a rope trap. These acts were not limited (8) family members, showing how social care extends (9) family ties.
(10) behaviours are likely instinctive, but others appear to be learned. Scientists plan to continue studying these behaviours to better understand how chimps learn and care for each other.
