Answer:
Variation within a species is known as speciation.
Explanation:
Speciation is a process through which the group of organisms belonging to the same species evolves into slightly distinct species. It happens as a result of the natural selection. These natural selections of species are due to the changes in the habitat due to habitat fragmentation, the introduction of a new niche, and genetic polymorphism. These natural selection of species or natural speciation are of 4 types:
1) Allopatric
2) parapatric
3) peripatric, and
4) sympatric.
