Lizards in an evolutionary tree : ecology and adaptive radiation of anoles, 2009 p. 205 ("Adaptive radiation is the evolutionary divergence of members of a clade to adapt to the environment in a variety of diffrent ways; the concept is important to evolutionaly biology and biodiversity studies")
Dict. of biology, Oxford, online Sept. 18, 2009 (evolution from one species of animals or plants of a number of different forms; as the original population increases in size it spreads out from its centre of origin to exploit new habitats and food sources; results in a number of populations each adapted to its particular habitat: eventually these populations will differ from each other sufficiently to become new species)
Dict. of Zoology, Oxford, online Sept. 18, 2009 (1. A burst of evolution, with rapid divergence from a single ancestral form, that results from the exploitation of an array of habitats; the term is applied at many taxonomic levels; the radiation of Darwin's finches in the Galpagos Islands resulted in a proliferation of species; 2. Term used synonymously with cladogenesis by some authors), Sept. 10, 2009 (cladogenesis; noun Biology; evolutionary change by the branching off of new species from common ancestral types)
