Extended data:

People can be defined from biological, spiritual and cultural levels, or a combination of these levels. Biologically, human beings are classified as primitive people, and the similarity of centromere fusion (balanced translocation) between chromosome 2 and gorilla A is greater than 16N, and the arm has been inverted many times, and other chromosomes have strong homology, so it is an advanced animal. On the spiritual level, people are described as being able to use the concept of various souls, which are considered to be related to the divine power or existence in religion. In cultural anthropology, man is defined as a creature who can use language and has complex social organization and scientific and technological development.
