1. Similarity between chimpanzees and humans
According to the research of scientists, chimpanzees and humans once lived in the same area. The ancestors of humans and chimpanzees may have separated five or six million years ago, and one of them became today's chimpanzee, while the other successfully evolved into humans. Chimpanzees are social animals, and their IQ is the highest except internal and external intelligence. Therefore, chimpanzee imitation is normal, and even few mathematicians think that humans should belong to the same family and genus as chimpanzees. When we are studying history, there is a saying that the difference between people and animals is that they can use tools. The most interesting thing is that chimpanzees can also use tools. Chimpanzees will stick twigs into termites' caves to lure small ants to climb the twigs and feed themselves.
Second, the IQ of chimpanzees.
Chimpanzees are self-conscious animals. When they want a mirror, they will not be scared by themselves in the mirror. They can clearly distinguish themselves in the mirror. Scientists have successfully taught chimpanzees to distinguish numbers from 0 to 9. Some chimpanzees can understand thousands of English words after language training, and even express them with the help of keyboard tools. Chimpanzees and human children are not only similar in intelligence, but sometimes even higher. Chimpanzees don't completely choose to walk upright. In fact, chimpanzees are very similar in size to humans, but they are covered with black hair, which makes them more robust. On rainy days, chimpanzees even cover their bodies with their hands.
Third, chimpanzee food.
Chimpanzees not only like fruits, but also animals such as baboons and antelopes. This shows that chimpanzees are actually omnivores, which is very similar to humans.
