A species is a population whose members are capable, at least potentially, of freely interbreeding and producing fertile offspring. A species is composed of a group or groups of interbreeding populations that are reproductively isolated from other such groups = AN INTERCOMMUNICATING GENE POOL. In practice, however, you seldom get a look at gene pools. This has led to two species concepts.
