The mechanism under which a new species develops from evolution is known as speciation.
A species is a group of organisms that can breed and produce fertile progeny while remaining reproductively isolated from other organisms.
Speciation can be aided by evolution, which would be a lengthy process that results in the accumulation of multiple tiny genetic changes known as mutations in a species.
Natural selection:
The adaptation and alteration of communities of living creatures are known as natural selection.
Individual creatures are naturally varied, meaning they differ in some ways.
As a result of this diversity, some people have characteristics that are more suited to their circumstances than others.
Variation in natural selection can result in speciation.
