1. Humans are not unique animals on the earth. Human beings have created language, religion, art and science because of their highly developed brains and aesthetic concepts, coupled with their desire for self-expression and relatively large brains.

2. Like other higher primates, human beings live in groups. People are particularly good at expressing themselves, exchanging opinions and organizing themselves in spoken and written language. Since the appearance of language, in order to distinguish the differences between individuals and identify different individuals, names have been produced; However, it has always been a controversial topic in "Nomenclatology" whether to produce "surname" or "name" first.

Man has created a complicated social structure, from family to country. Social communication between human beings has created a wide range of traditions, customs, religious systems, values and laws, which have become the foundation of human society.

Extended data

Man (scientific name: Homo sapiens, meaning "intelligent man") is a species of Homaloptera. Mitochondrial DNA and fossils prove that humans originated in East Africa about 5 million years ago. Primates belonging to the hominid family include chimpanzees, gorillas, orangutans, gibbons and fingered apes. It is found that human chromosome 2 may be the product of centromere fusion of chimpanzee chromosome 3 (balanced translocation), and other chromosomes have strong homology. Zoologist D. Moliis joked that human beings are naked apes, and wrote down the origin of human behavior from various angles. From Ape to Man, written by Engels, represents the classic study of the origin of man by Marxism.
