Extinction

From CasGroup

'''Extinction''' is the state or process of a [[Species|species]], family, or larger group being or becoming extinct. In modern usage, the word refers to "a terminal event in the history of a population, species, or higher taxon" (Keller and Lloyd, 1992). Extinction of a [[Species|species]] leaves an empty [[Niche|niche]]. It can happen if the niche or habitat vanishes or if the [[Fitness|fitness]] is not high enough. == Links == * Wikipedia link for [http://en.wikipedia.org/wiki/Extinction extinction] == References == * Evelyn Fox Keller and Elisabeth A.
