What are the forms of natural selection?

Currently, several forms of natural selection are distinguished, the main of which are stabilizing, moving and disruptive.

Selection form In what conditions does it
Selection direction Examples
Moving constantly changing conditions the formation of new species loss of limbs in a snake
Stabilizing relatively stable conditions preservation of the genotype of the species coelacanth, oposum, ginkgo

In both cases, we have genetic diversity. But in the first case, this leads to the emergence of new species, and in the second they are eliminated.

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.
