United States Endangered Species Act
For the purposes of the Endangered Species Act a "species" is defined to include "any distinct population segment of any species of vertebrate fish or wildlife which interbreeds when mature." However, the Act does not define what constitutes a "distinct population segment," but this is generally considered to be synonymous with an evolutionarily significant unit, so that it must:
- be substantially reproductively isolated from other conspecific populations, and
- represent an important component in the evolutionary legacy of the biological species
