Biological systematics is considered to be the study of the diversity of life on the planet earth, both past and present, and the relationships among living things through time. Systematics, is used to understand the evolutionary history of life on earth.
Systematics is often used synonymously with "taxonomy" and scientific classification." However, taxonomy is the describing, identifying, classifying, and naming of organisms. Classification is focused on categorizing organisms within specific groups that show their relationships to other organisms.
Systematics uses taxonomy as a means to understand organisms, as nothing about an organism's relationships with other living things can be understood without it first being properly studied and described in sufficient detail to identify and classify it correctly. Scientific classifications are aids in recording and reporting information to other scientists and to laymen.
A scientist who specializes in systematics is called a systematist. A systematist must be able to use existing classification systems to insure proper identification and classification of species.
This Systematics section of the NBII provides users with access to sites that provide biological names of organisms and their classification that shows the evolutionary relationship among species.
