A '''species''' is a reproductively isolated, independent evolutionary unit which occupies a certain [[Niche\|niche]]. By definition, species are in biology "the lowest-level classifactory or taxonomic unit for biological organisms" (Keller and Lloyd, 1992). In biology it is a taxonomic group whose members can interbreed: a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. It is one of the basic units of biological classification.

	The rise of a new species from an ancestor is called [[Speciation\|speciation]].		The two defining features are '''interaction''' and '''similarity''': frequent interaction and interbreeding leads to similar individuals, which can be classified by different taxonomic groups. classes, and categories, and similar individuals more frequently interact than dissimilar ones.

A '''species''' is a reproductively isolated, independent evolutionary unit which occupies a certain niche.
In biology it is a taxonomic group whose members can interbreed: a group of living organisms consisting of
similar individuals capable of exchanging genes or interbreeding.
It is one of the basic units of biological classification.

The rise of a new species from an ancestor is called [[Speciation speciation]].
