Physiology Comparative

Comparative physiology is a branch of evolutionary physiology that studies the similarities and differences in functions among different representatives of animals in order to determine the causes and general laws of changes in functions or the emergence of new functions.

Comparative physiology allows us to understand how different functions change during evolution and how they can be used to improve the lives of animals. It also helps to understand what processes occur inside the body and how these processes affect its functioning.

Comparing the functions of different animal species can help determine which functions are most important for the survival and reproduction of the species, and which functions can be modified to improve living conditions.

For example, comparative physiology can help understand why some animals have long necks or sharp teeth, while others have short necks or blunt teeth. This may be due to the fact that long necks help animals reach high places, and sharp teeth help them hunt larger prey.

In addition, comparative physiology can be used to develop new treatments for diseases in animals. For example, if we know which functions are associated with certain diseases, we can develop drugs that target those functions.

In general, comparative physiology is an important branch of evolutionary physiology and is of great importance for understanding animal life and developing treatments for diseases.

The section of evolutionary physiology that studies the similarities and differences of various functions in various representatives of the animal world in order to identify the causes and general patterns of changes in functions or their appearance is first called comparative physiology. The main task of comparative physiology is to identify the commonality of functional bases in related species of organisms, making it possible to substantiate the unity of the paths of origin of such life forms. The commonality of certain manifestations of physiology serves as the main criterion for the relationship between living organisms. In this regard, interest in the comparative study of physiology increases with the development of knowledge about phylogenesis, which led to the emergence of an integrative science - zoological (physiological) genetics, combining data from animal genetics, cytology and physiology.
