This type of selection tends to narrow the variation in the phenotype over time. This is the most common type of selection because it is associated with the adaptation of an organism to the environment.

How many forms of natural selection are there?
Directional selection, stabilizing selection and disruptive selection are three types of natural selection. They are also examples of adaptive evolution. Natural selection is the mechanism of evolution which favors organisms that are better adapted to their environments.

For Darwin himself these five theories were apparently much more a unity than they appear to a person who analyzes them with modern hindsight. The five theories were: (1) evolution as such, (2) common descent, (3) gradualism, (4) multiplication of species, and (5) natural selection.
What is natural and artificial selection?
Natural selection is based on the adaptive characteristics of animals. Artificial selection is based on the desirable characters selected by humans. Only beneficial or favorable traits are inherited over the successive generations by natural selection.
What are 5 principles of natural selection?
Natural selection is a simple mechanism that causes populations of living things to change over time. In fact, it is so simple that it can be broken down into five basic steps, abbreviated here as VISTA: Variation, Inheritance, Selection, Time and Adaptation.
What are the 4 parts of Darwin’s theory of natural selection?
There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
