Classification Lecture and Beginner Activity
Classification of animal
s is a way to put them into groups that share the same traits.
This is an important way to see how animals are related to each other. They are divided using traits or characteristics (like whether or not they have a backbone).
The way we classify animals and plants was created by a scientist named Linnaeus. The Linnaeus system classifies plants and animals on seven levels using Latin and Greek words. With the development of genome science, the biological connection between animals is beginning to alter and over time there will be a more accurate classification system. But, for now, scientists accept the classic Linnaeus system which can be shown in the following way.
All living things are classified on the seven levels:
An example of how this works in an Eastern Chipmunk is:
- Domain: Eukaryota
- Kingdom: Animalia animal
- Phylum: Chordata has a backbone
- Class: Mammalia has a backbone, nurses young
- Order: Rodentia has a backbone, nurses young, long, sharp front teeth
- Family: Scuridae has a backbone, nurses young, long, sharp front teeth, bushy tail
- Genus: Tamias has a backbone, nurses young, long, sharp front teeth, bushy tail, climbs trees
- Species: striatus has a backbone, nurses young, long, sharp front teeth, bushy tail, climbs trees, stripes
Try this simple Classification Activity with your class, using a simple dichotomous key.
