A process in the breeding of organisms by which the scientist chooses to only those forms having certain desirable characteristics is called artificial selection.

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.

In natural selection, the difference in reproductive success based on a particular trait is driven by natural processes like predators, weather conditions, and environmental constraints.

Artificial selection is imposed by humans on other organisms.

It affects the process of natural selection through change in environmental conditions.
