The smartest animal on earth

The smartest animal on earth is the chimpanzee. Chimpanzees are primates that can distinguish different colors and make 32 sounds with different meanings. Able to use simple tools, they are the most intelligent animals known after humans. Its behavior and social behavior are more similar to humans, which is of great significance in anthropological research.

Chimpanzees are 70-92.5 cm long, 1-1.7 meters tall when standing, and weigh 45-80 kg. They have short black body hair, usually one white spot on their buttocks, a grey-brown face, extra-large ears that protrude to both sides, deeply sunken eye sockets, and tooth-like shapes. Same as humans; tailless. Life span is 35-40 years.

Chimpanzees are the closest living relatives to humans, and they are also the animals with the highest level of intelligence besides humans today. A few scientists who do not believe in anthropocentrism advocate that chimpanzees should be separated from the genus Chimpanzee and placed with the genus Homo. There are even a handful of scholars who believe that, in a sense, humans are the third type of chimpanzee.

Chimpanzees have feelings and will grieve the death of a relative, and other members of the group will express condolences to the dead brother. Scientists have successfully taught a chimpanzee to recognize Arabic numerals. It can also arrange numbers in order from 0 to 9 and remember up to 5 digits. After receiving language training, some chimpanzees can understand thousands of English words and can "speak" with the help of keyboards and other tools. Chimpanzees and human infants are obviously more similar in intelligence than in appearance.

The ABO blood type of chimpanzees is mainly A, with a small amount of O type, but no B type. M blood types and N blood types are also found. Chimpanzees have 48 chromosomes (24 pairs). The sequence of amino acids on chimpanzee cytochrome C is the same as that of humans.

Chimpanzees are curious, restless, quick and clever in their movements. During the day, they often gather together and make a lot of noise, which is very chaotic. There will be a fuss almost every 20 minutes, and they often use the dense branches and vines to play "beating". Games like "Swing" and "Hide and Seek".

Chimpanzees are the higher animals most similar to humans. Studies have shown that some chimpanzees can not only master certain technologies and sign languages after training, but can also use computer keyboards to learn vocabulary, and their abilities are even better than those of two-year-old children.
