Give three examples of reproductive barriers AND Explain how these barriers could lead to
speciation over a long period of time.

temporal isolation which causes the two populations of one species are isolated this way, they no longer reproduce with each other due to differences in mating times, ecological isolation which implies reproductive isolation of populations inhabiting separate niches as a result of divergent selection of ecologically influenced characters, and behavioral isolation which occurs when populations of the same species begin to develop different behaviors that are not recognized or preferred by members in another population.
