Scientists classify (or group/sort) living things according to the similarities that they share. Think about your science binder - it is set up for you to easily find certain work or put your work away. If I return a quiz to you, what section would you put it in? Your "Tests & Quizzes" section, of course! If I want to collect last night's homework assignment, it should take you 5 seconds to take it out of your "Classwork & Homework" section! Your work is classified according to what the assignment is, and the divider labels are your taxonomy!
A science example: plants contain a chemical called chlorophyll that they use to make their own food (it also makes them green). Every member of the plant kingdom shares this characteristic.
Each kingdom can then be broken into small groups, or phyla, of organisms that share even more similarities. Each phylum is divided even further into several classes; each class is divided into orders; each order is divided into families; families are divided into genera (sing. genus); and finally, each genus is divided is divided into many species.
The order of classification of the human is :
- Kingdom - Animalia
- Phylum - Chordata
- Class - Mammalia
- Order - Primates
- Family - Hominidae
- Genus - Homo
- Species - sapiens
Friday's quiz will require that you know the order of classification of living things (kingdom through species).
