For the very first time, scientists observed chimpanzees in Gabon, West Africa using bugs to their injuries and the injuries of others. In a research study released on February 7, 2022, in the journal Current Biology, researchers explain this wound-tending habits and argue that it is proof that chimpanzees have the capability for prosocial habits that have actually been related to compassion in people.
In November 2019, Alessandra Mascaro, a volunteer at the Ozouga Chimpanzee Project, observed a chimpanzee called Suzee checking an injury on the foot of her teen child, Sia, capturing a bug out of the air, putting it into her mouth, and after that using it onto the injury. Researchers of the Ozouga Chimpanzee Project had actually been studying this group of chimpanzees in Loango National Park for 7 years however had not experienced habits like this prior to. Mascaro took a video of the mom and child and revealed it to her managers, Tobias Deschner, a primatologist with the job, and Simone Pika, a cognitive biologist at Osnabr ück University.
“In the video, you can see that Suzee is first looking at the foot of her son, and then it’s as if she is thinking, ‘What could I do?’ and then she looks up, sees the insect, and catches it for her son,’” Mascaro states. The Ozouga group began to keep an eye on the chimpanzees for this kind of wound-tending habits, and over the next 15 months recorded 76 cases of the group using bugs to injuries on themselves and others.
This wasn’t the very first time that nonhuman animals had actually been observed self-medicating. Researchers have actually reported that bears, elephants, and bees do it too. What is exceptional is that up until now, insect applications have actually never ever been observed which the chimps not just treat their own, however likewise the injuries of others.
Pika argues that the act of using a bug to another’s injuries is a clear example of prosocial habits– habits that acts in the very best interests of others, instead of simply oneself. “This is, for me, especially breathtaking because so many people doubt prosocial abilities in other animals,” she states. “Suddenly we have a species where we really see individuals caring for others.”
The research study group does not understand precisely which bugs the chimpanzees are utilizing or what their medical homes are. “Humans use many species of insect as remedies against sickness—there have been studies showing that insects can have antibiotic, antiviral, and anthelmintic functions,” statesPika The scientists have actually likewise thought that the bugs may have calming homes that might supply discomfort relief.
The Ozouga group now intends to determine the bugs being utilized by the chimpanzees and to record who is using bugs to whom. “Studying great apes in their natural environments is crucial to shed light on our own cognitive evolution,” statesDeschner “We need to still put much more effort into studying and protecting them and also protecting their natural habitats.”
