Prove that natural selection drives the evolutionary process?

Mutations are undirected changes in the body. Natural selection is the directing factor of evolution, which leads to the appearance of adaptations in organisms to the specific conditions of their habitation. For example, the appearance of a dark form of a birch moth in cities on trees of birch trunks covered with metallurgical soot. the initial form of this species is camouflage of a birch trunk – spotty light color. Thus, when conditions change, selection can change its direction.

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.
