taxonomic hierarchy

Taxonomic hierarchy is the system used by scientists to organize and classify living things. It starts with broad categories and narrows down to specific ones. The main levels, from general to specific, are: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. For example, humans are classified as: Domain - Eukarya, Kingdom - Animalia, Phylum - Chordata, Class - Mammalia, Order - Primates, Family - Hominidae, Genus - Homo, and Species - Homo sapiens. This system helps in understanding the relationships between different organisms and their evolutionary history.
