Biological Species Concept. The biological species concept defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance.Although appearance is helpful in identifying species, it does not define species.Appearance isnt everything.1  Organisms may appear to be alike and be different species. 2  For example, Western meadowlarks (Sturnella neglecta) and Eastern meadowlarks (Sturnella magna) look almost identical to one another, yet do not interbreed with each otherthus, they are separate species according to this definition.ppearance isnt everything. 1  Organisms may appear to be alike and be different species. 2  For example, Western meadowlarks (Sturnella neglecta) and Eastern meadowlarks (Sturnella magna) look almost identical to one another, yet do not interbreed with each otherthus, they are separate species according to this definition.
biological species concept. Members of the same species are capable of interbreeding, producing viable offspring, and cannot produce viable offspring with members of other species. This is one of several concepts that define a species, and is the most commonly used and accepted of those concepts.he most common method for species differentiation is the biological species concept, which defines a species as a population of organisms that can interbreed to produce viable, fertile offspring.
