biological information is given with reference to a species. There is a whole discipline, taxonomy, dedicated to the delimitation of species, which requires a species concept. Species concepts do not only define what a species is, but by defining what a species is, they also define what speciation is. Thus, research programs
Phenetic Species Concept. • A quantitative approach to systematics that seeks to classify organisms on the basis of their overall similarity. • Based on numerical taxonomy, which measures and records similarities for large numbers of characters. • Phenetic species concept defines a species as a set of organisms that look.

Why are species important. • Much of our systematic, taxonomic, ecological, physiological, etc. studies are conducted at species level. • The species is considered by most to be the unit of evolution. Thus, the primary unit of biogeography, selection, adaptation, speciation, etc.
