What distinguishes a Genus from a Species?

A Genus is classified as a taxonomic rank that encompasses one or more species that share common characteristics and evolutionary history, making it broader in scope. In contrast, a Species represents the most specific level of classification, identifying a single group of organisms that can reproduce among themselves and produce viable offspring. The hierarchical structure of biological classification positions the Genus above the Species, illustrating that multiple related species can belong to the same Genus due to shared traits or closer evolutionary relationships. Thus, the distinction between them lies in the levels of specificity—Genus being more general and encompassing multiple related species, while Species is the most specific classification within that hierarchy.
