Important Concept Of Species The biological species concept states that a species is a group of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups. He argued for what came to be called the Biological Species Concept (BSC), that a species consists of populations of organisms that can reproduce with one another and that are reproductively isolated from other populations, though he was not the first to define "species" on the basis of reproductive compatibility.
