Chimpanzee:Our Closest Relative in the Wild Chimpanzee is the animal most like humans,so studying them in the wild gives scientists insight into the origins of our own social behaviour,our communication,and now,how we care for one another.
The wound care of chimpanzees involves various techniques:directly licking the wound to remove debris and potentially adding antibacterial compounds in the saliva;pressing the wound after licking their fingers;patting with leaves;and chewing plant leaves and applying the juice to the wound.These actions show that chimpanzees have a high level of intelligence and social care.
Scientists have observed that chimpanzees not only care for their own wounds but also help other group members treat injuries.For example,a young chimpanzee was seen helping an older one clean a deep wound on its arm.This kind of behaviour is similar to human medical care,which surprised many researchers.
In a 10-year study in the Congo Basin,Dr.Jane Goodall found that chimpanzees can learn new skills from each other.They can use sticks to get termites from their nests,and this skill is passed down from older chimpanzees to younger ones.This shows that chimpanzees have the ability to learn and teach,just like humans.
Dr.X,a primatologist,said, "Chimpanzees' social behaviour and learning ability remind us that we are not the only intelligent species on Earth.We should respect and protect them." Due to deforestation and hunting,the number of wild chimpanzees has dropped by 60
% in the past 30 years.Scientists are working hard to protect their habitats and stop illegal hunting.
