What is the concept of man?

Concept of human beings: creatures who can use language, have complex social organizations and scientific and technological development, especially those who can establish groups and institutions to achieve the purpose of mutual support and assistance. People can be defined from biological, spiritual and cultural levels, or a combination of these levels.

1. Biologically, human beings are divided into primitive people, genera and races. The similarity of centromere fusion (balanced translocation) correlation pattern between chromosome 2 and orangutan A is above 16N, and the arm is inverted many times. Other chromosomes have strong homology, so it is an advanced animal.

2. 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.

3. In cultural anthropology, people are defined as creatures who can use languages, have complex social organizations and scientific and technological development, and especially can establish groups and institutions to achieve the purpose of mutual support and help.

People's various periods

1, infancy: refers to the period from birth to 1 year. It is the fastest growing period after a child is born. The baby is a child under 1 year. Babies grow and develop particularly rapidly at this stage, which is the most vigorous stage of human life.

2. Early childhood: 1 to 3 years old, called early childhood. This period is a period when children's intelligence develops very rapidly, when children's special talents begin to appear, and when their character and quality begin to form. The formation of personality in early childhood is an important basis for future personality development.

3. Childhood: from the end of childhood to before entering primary school, that is, 3 to 7 years old, it is school age. From primary school to adolescence, it generally refers to 7 years old to 12 years old, and also includes the life stage from fetus to adolescence.

4. Adolescence: refers to the first reproductive period marked by the maturity of reproductive organs and the development of secondary sexual characteristics. In humans and higher primates, it is marked by the first menstruation of women. Adolescence is a critical period for the rapid growth and development of human body. It is also the second growth and development peak in life after infancy.

5. adulthood: generally refers to the period of 24 years old or 25 to 60 years old. Usually people divide this period into two stages: early adulthood, from 24, 25 to 40 years old; 40 ~ 60 years old in later adulthood. The characteristics of physical and mental development in adulthood are relatively stable. This period is equivalent to physical maturity.

6. Old age: the last stage of life process. It is characterized by obvious degeneration of various organs and tissues of the body, corresponding changes in psychology, and obvious aging gradually. From the medical and biological point of view, the age after 60 or 65 is defined as old age, in which the age after 80 is old age and the age after 90 is longevity.
