Unit 8 – Classification Study Guide

1. What are the levels of hierarchy of classification?

Information about physical features and activities is arranged in a hierarchy of increasing specificity. The levels in the accepted hierarchy include: domain, kingdom, phylum, class, order, family, genus and species.

2. What are the three domains of organisms? Current classification systems now generally recognize the categorization of organisms into three domains: Archaea, Bacteria and Eukarya.

3. Why does classification continue to change?As our technology improves so does our understanding of the natural world. As living things are constantly being investigated, new attributes (physical and chemical) are revealed that affect how organisms are placed in a standard classification system. Evolution and technology both impact classification.

4. What is binomial nomenclature and why is it used in classification?

The scientific name of a species is a two-name naming system known as binomial nomenclature and consists of the Genus and species names. We use these names so that regardless of language, the exact species being discussed is the same species.
