How does behavioral isolation cause speciation?
Behavioral isolation prevents members of a species from mating. It’s one of many processes that lead to speciation. Through this process, members of a population diverge over time in their behaviors. This continues until they can no longer mate.
What does social isolation do to a person?

What are behavioral barriers?
How do species become reproductively isolated?
Species are kept distinct from one another by prezygotic and postzygotic barriers. These barriers keep organisms of different species from mating to produce fertile offspring, acting before and after the formation of a zygote, respectively. These barriers maintain the reproductive isolation of species.
