Taxonomic hierarchy is a system used by scientists to classify and organize living organisms. It arranges them into categories based on shared characteristics, starting from broad groups to more specific ones. The main levels of this hierarchy include domain, kingdom, phylum, class, order, family, genus, and species. For example, humans belong to the species Homo sapiens, which is part of the genus Homo. This classification helps scientists communicate about different organisms and understand their relationships. By using taxonomic hierarchy, researchers can identify how closely related different species are, which is essential for studying evolution and biodiversity. For instance, the lion and tiger are both part of the family Felidae, indicating they share a
