A researcher is comparing two populations of birds with similar morphology that live in similar niches. Male birds in one population build a nest before attempting to court a female, while males in the other population build the nest in cooperation with the female. Is it likely the researcher will classify these birds as the same species?arrow_forwardBehavioral isolation is considered which type of reproductive barrier? a prezygotic b postzygotic c overlapping d heritablearrow_forward
