Extended data:

People can be defined from biological, spiritual and cultural levels, or a combination of these levels. Biologically, human beings are classified as hominids, and the similarity of centromere fusion (balanced translocation) association mode between chromosome 2 and orangutan A is more than 16N, and the 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 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.
