17.3-The Process of Speciation

species: a population or group of populations whose members can interbreed and produce fertile offspring speciation: the formation of a new species reproductive isolation: the inability of a species to breed successfully with related species due to geographical, behavioral, physiological, or genetic barriers or differences behavioral isolation: when two populations that are capable of interbreeding develop differences in courtship rituals or other behaviors geographic isolation: when two populations are separated by by geographic barriers such as mountains or rivers temporal isolation: when two or more species reproduce at different times
