In biological classification, the taxonomic hierarchy is the process of arranging organisms into successive levels of rank. For animals, the standard sequence from the most inclusive (broadest) to the most exclusive (most specific) category is:

Kingdom: The highest and broadest category (e.g., Animalia).

Phylum: Groups together classes with common body plans (e.g., Chordata).

Class: Includes related orders (e.g., Mammalia).

Order: Comprises one or more related families (e.g., Primates).

Family: Includes various genera that share similarities (e.g., Hominidae).

Genus: A group of closely related species (e.g., Homo).

Species: The basic and most specific unit of classification (e.g., sapiens).
