Concept of a species

A species is a group of living organisms that can interbreed and produce fertile offspring under natural conditions. Members of the same species share similar physical characteristics and genetic makeup, which distinguish them from other groups. This classification helps scientists understand biodiversity and the relationships between different organisms. For example, all domestic dogs belong to the species *Canis lupus familiaris*, while wolves are *Canis lupus*, reflecting their close genetic connection. The concept of a species is fundamental to biology, aiding in the study and conservation of the world’s biodiversity.
