RC 3 STAAR Review: Evolution/Taxonomy

Why do we use the system of taxonomy for classifying organisms?

• to classify animals based on their fur color

• to organize organisms based on their ability to reproduce

• classify organisms based on their height

• to avoid confusion and have the same name for an animal

The scientific name of an organism contains which two levels?

• phylum and species

• domain and kingdom

• genus and species

• order and domain

Two animals in which of the following groups would be the most closely related to each other?

• domain

• species

• genus

• order
