Why classify? • There are millions of different living things in the world • Making sense of all those living things requires classification • Classifying living things makes it easier for biologists to answer questions
Levels of Classification • • Domain Kingdom Phylum (plural: phyla) Brain. Pop Classification Class Order Family Genus (plural: genera) Species (contains only one kind of organism)
