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.
