It is the process where one species splits into two or more species.
What are prezygotic barriers?

What are postzygotic barriers?

What is temporal isolation?
Breeding season doesn’t match between males and females.
What is behavioral isolation?
Based on the behavior of species in the context of mating rituals and species.
