A species is a fundamental biological classification unit representing a group of organisms capable of interbreeding and producing fertile offspring.
In taxonomy, species are defined by shared characteristics, genetic similarity, and a common evolutionary lineage. Each species occupies a distinct ecological niche, contributing to biodiversity.
Scientifically, the binomial nomenclature assigns a unique two-part name to each species, such as Homo sapiens for humans. The concept of species is central to understanding biodiversity, evolution, and ecological relationships in the natural world, forming the basis for biological classification and research.
