Final answer:
Biological classification is a systematic method of sorting organisms using a hierarchical structure from domains to species.
Step-by-step explanation:
Biological classification is a method by which biologists sort and categorize species of organisms. This system of taxonomy was initially developed by Carl Linnaeus and has progressed to include phylogenetic principles. Humans are categorized within this taxonomic classification starting from domain down to species. For humans, the categories are Domain: Eukarya, Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Primates, Family: Hominidae, Genus: Homo, Species: sapiens.
Modern taxonomy uses a hierarchical structure, beginning with the most inclusive category, the domain, and progressing through kingdom, phylum, class, order, family, genus, and species. We use binomial nomenclature to refer to an organism by its genus and species name, as established by Linnaeus. For example, humans are scientifically known as Homo sapiens.
In classifying organisms, scientists examine characteristics such as symmetry, germ layers, coelom, and embryological development. These traits help to determine the specific taxonomy of an organism, allowing for a clear understanding of its evolutionary history and relationships with other organisms.
