The biological species concept is the most widely accepted species concept. It defines species in terms of interbreeding. For instance, Ernst Mayr defined a species as follows: "species are groups of interbreeding natural populations that are reproductively isolated from other such groups."

The diversity of contemporary species concepts has been reviewed in several recent publications (17– 20)andwillnotberepeatedhere.Forthepresentdiscussion,the important thing to recognize is that different contemporary species concepts are based, in part, on different biological properties. For example, the biological species concept empha- The biological species, according to Grant (1957), is defined as “a community of cross fertilising individuals linked together by bonds of mating and isolated reproductively from other species.” In short, a biological species is formed by “groups of interbreeding natural populations that are reproductively isolated from such other groups.” 2021-04-02 · biological species concept Quick Reference The view that the species comprises populations (or groups of populations) that are reproductively isolated from each other, i.e. that species should always be biospecies. Biological Species Concept Species are groups of actually or potentially interbreeding populations that are reproductively isolated from other such groups (Mayr, 1942).

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.

2018-05-18 · biological species concept (BSC) The concept of a species as a group of populations whose members are capable of interbreeding successfully and are reproductively isolated from other groups. This concept became influential during the late 19th and early 20th centuries, largely replacing the typological species concept favoured by pioneer naturalists. ” Accordingly, the concept of species which works best for animals, becomes entirely a matter of judgement. The approximately 5000 species of bacteria and archaea constitute a surprisingly small number, considering their relatively early evolution, genetic diversity, and ability to reside in all ecosystems on Earth.
