We know that people can be nice, but what about animals?
Some scientists think they can. Animals that live in groups, like chimpanzees and elephants, have to be nice to each other to survive. However, animals sometimes act nicely even when they don’t need to. Here are four stories.
One day in southern Australia, Leonie Allan was walking her dog Rex when she came across a dead kangaroo. A car hit it—sadly, this happened frequently in the area. But later that day, Rex went back to the body. There was a small baby kangaroo in its pouch! Rex pulled the baby out gently, brought it home, and placed it at Leonie’s feet. He saved the kangaroo’s life, and the two became good friends.
Geza Teleki is a scientist who studies chimpanzees in Tanzania. One day, Geza hiked far away from his campsite. He didn’t have any food with him, so he tried to get some fruit from a tree. But the tree was too tall. A young chimpanzee watched Geza curiously as he tried to get to the fruit. It then climbed up the tree, picked some fruit, and gave it to Geza!
An elephant in Kenya hurt its trunk. It needed help because it couldn’t put food into its mouth. Researcher Kayhan Ostovar watched silently. He saw the elephant show its injured trunk to a healthy elephant. The healthy elephant didn’t need any more information. It took some leaves and put them carefully into its friend’s mouth.
Hippos and crocodiles live together in rivers, and they usually get along. But Karen Paoilillo, a wildlife expert in Zimbabwe, saw something interesting. One day, a crocodile tried to eat a monkey that was next to a river. A hippo ran quickly to the crocodile and chased it away. Why did the hippo attack the crocodile? Karen says that sometimes hippos like to protect other animals.
