TAXONOMY

Branch of Biology that deals with classification and naming living things.

Aristotle classified living things into only two categories—plants or animals.

So why classify further? It provides organization and identification for

studying organisms. Common names vary from place to place and

many do not accurately define a species. Example: jellyfish
