Kamila Bruce · Answer 1

Speciation is when a new species starts to exist, right? Since reproductive isolation is when members of the same species stop breeding with each other, it is exactly what would stop that potential new species from prevailing.

Aniya Stone · Answer 2

This can be caused by mating differences, sterility or environmental barriers that eventually lead to the adaptive splitting into two species. However, reproductive isolation is not sufficient but internal barriers to gene flow are required for speciation to evolve.
