Often the term species is used rather than ESU, even when an ESU is more technically considered a subspecies or variety rather Evolutionarily Significant Units Biodiversity conservation efforts tradition-ally focus on maintaining one or more mini-mum viable populations (MVP) of a focal taxon that, in theory, should persist on ecological time scales (Shaffer 1981).

Evolutionarily significant unit

Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction. Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation. Evolution occurs when evolutionary processes such as natural selection and genetic drift act on this variation, resulting Evolutionarily Significant Units, Distinct Population Segments, and the Endangered Species Act: Reply to Pennock and Dimmick.
