The Typological Species Concept

The Typological Species Concept classifies species based on a set of fixed, idealized appearance traits, called a "type." Under this idea, each species is thought to have a specific, unchanging form that defines it, regardless of variations within the group. It emphasizes identifying and comparing the characteristic features of organisms to determine if they belong to the same species. This approach was common historically but has limitations, as it can overlook natural variation and changes within populations. It primarily relies on physical similarity and shared traits to categorize species.
