Chimps Might Use Insects as First Aid, Scientists Find

research worker have documented a remarkable behavior among wild chimpanzee : chimp applying insects to wounds on themselves or others , perhaps as a variety of first economic aid . Little is still known about the practice , but the researcher mistrust it to be the latest exemplar of altruistic behavior in nonhuman animals .

The act was reportedly first give away in 2019 by Alessandra Mascaro , a volunteer at theOzouga Chimpanzee Projectin Gabon . Mascaro see and was able to record a distaff Pan troglodytes dub Suzee test a wound on her Logos Sia ’s foot . Suzee then caught a fly worm , put it in her mouth , and applied the worm to Sia ’s wounding .

Intrigued , Mascaro and her colleagues get down to watch for the behavior among chimpanzees in the group . Over the next 15 month , they documented the same exercise hap 76 clock time , with chimpanzees doing it to themselves or others . The team ’s findings werepublishedMonday in Current Biology , complete with theoriginal videoof Suzee and her son Sia .

fauna using their rude environment toself - medicateis far from unheard of . Many creatures , including bear , apes , and cervid , are think to ingest plants with medicative properties . And given that the louse are being implement to wounds , the investigator surmise that the enactment is some form of medical discourse . If it is , it seems to be the first instance of insect therapy ever spotted in the wilderness .

“ The software of insects or insect parts to an somebody ’s own injury or the wound of a conspecific has never been reported , ” the written report authors wrote .

While the practice might seem egregious , the chimps may know something we do n’t about the medicinal benefits of certain bugs . To this day , homo apply bloodsucker and maggots to aid heal wound , and some inquiry has suggested that insect could carry antimicrobic properties . It ’s also possible that they could have a painkilling consequence .

The discovery suggests a degree of chimp compassion as well . Most example of insect first aid the team saw knotty ego - treatment . But sometimes , as with Suzee and her son , the Pan troglodytes assist patch others up . The act looks like a all the way - cut showcase of “ prosocial behavior”—doing something for another without an obvious benefit to oneself .

“ This is , for me , especially breathtaking because so many people doubt prosocial abilities in other fauna , ” said bailiwick source Simone Pika , a cognitive biologist at Osnabrück University in Germany , in astatement . “Suddenly we have a species where we really see individuals give care for others . ”

That said , it ’s always difficult to interpret the motive behind nonhuman fauna behaviors , and much is still undecipherable about this fussy natural process . Next , the researchers plan to adjudicate calculate out which specific insect are being used by the chimps and why .
