Why is the XX century considered the century of biology?

XX century – for biology as a science was extremely fruitful. The regularities of the process of evolution and transmission of hereditary information are revealed, the properties and nature of reproduction of biosystems are revealed, the mechanism of photosynthesis is established, the ecological laws of the life of nature and the existence of the biosphere are determined, the features of the structural levels of living matter are investigated. It was in this century that biology ceased to be a descriptive natural-philosophical field of knowledge, passing into the category of fundamental sciences, taking a leading place among them.
Biology forms ideas about the laws of existence of nature and man as a part of it, reveals the structure of the living world, the directions of its development in interaction with society and the environment.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
