Classification Systems

Description

Research in biology would be impossible without a common framework for grouping and distinguishing species. This program looks at the classification system first proposed by Linnaeus and shows how it developed into the organizational structure used in the life sciences today. Viewers also learn how new scientific names are created and how the existing system has been further refined using DNA studies. Overviewing the five kingdoms and their major subdivisions, the film describes how biologists use dichotomous keys to classify specimens and provides a helpful example of constructing a key.
