Social insects live in the form of societies, which in some ways are similar to human societies. In both types of societies, there is a division of labor. In insects societies, certain insects have the duty of reproduction, the workers collect food while the soldiers defend the land. In the same way human groups such as farmers and shopkeepers have specialized functions in producing good and providing services to the society.

   Insects and human societies are also alike in which individual members of the society work together. White ant workers work together to build nests. Similarly in human societies, engineers, architects, town planners and construction workers unite to build cities.

   The nests of social insects are as complex as a man-made city. In some insect nests special places are provided for the young and for food storage. Many nests also have devices for regulating the temperature. So insect nests are as functional as human houses.

   It is not surprising, therefore, that many similarities have been made between social insects and human societies. It must not be forgotten, however, that insect social behavior is determined by nature. Insects show no ability for learning or for developing a social tradition based on learning.

Social insects live in the form of societies which in some ways are similar to human societies. In both types of societies there is a division of labour. In insect societies certain insects have the duty of reproduction (繁殖); the workers collect food while the soldiers defend the land. In the same way human groups such as farmers and shopkeepers have specialized functions (作用) in producing goods and providing services to the society.

Insects and human societies are also alike in that individual (个体的) members of the society work together. White ant workers work together to build nests. Similarly, in human societies engineers, architects (建筑师), town planners and construction workers unite to build cities.

The nests of social insects are as complex (复杂的) as a man-made city. In some insect nests special places are provided for the young and for food storage. Many nests also have devices for regulating the temperature. So insect nests are as functional as human houses.

It is not surprising, therefore, that many similarities have been made between social insects and human societies. It must not be forgotten, however, that insect social behavior is determined by nature. Insects show no ability for learning or for developing a social tradition based on learning.
