Why do women have children and men carry on the family line?

In the long development of human society, the contradictory movement between productive forces and production relations plays a decisive role. In the agricultural society, due to physical differences, there is an extremely wide gap between men and women in the provision of productivity, and men have absolute control over social resources. This leads to the fact that women can only rely on men to survive in the family, and men become the dominant family.

The concept of carrying on the family line is also related to the social status of men. In feudal society, men were the main labor force in families and families, responsible for providing food and other necessities of life. Due to the requirements of agricultural production mode, families need to inherit blood to ensure the continuity of families and the inheritance of land. Therefore, men become representatives of blood, and only sons can carry on the family line.

In addition, the dependence of feudal society on men also led to women being regarded as accessories of men. Women often obey men's arrangements at home and cannot participate in social activities freely. This unequal social status makes it impossible for women to inherit the blood on behalf of the family.

In short, in the long historical period, due to the contradictory movement of productivity and production relations and the social status of men, the phenomenon that fertility is borne by women and inheritance is mainly borne by men has been caused.
