the diversification of species into separate forms that each adapt to occupy a specific environmental niche
rapid speciation and diversification of a group into unoccupied ecological niches
the progressive modification of a structure in response to different environments
the evolution of a single ancestor species into several new species within a relatively short period of time and in a certain geographic area The plants and animals of the Galápagos Islands are a result of adaptive radiation, where one plant or one animal species diversified into many species that fill a variety of ecological roles For example, more than a dozen species of finches evolved from a single founding species that colonized the islands from the mainland of South America
the evolution [2: speciation ] of a diverse range of species occupying many habitats and new niches from some single ancestral stock (phyletic line) Lon-term associations (interactions) can produce niche diversification, a frequently observed situation in which actual or potential competitors specialize to use slightly different components of the local environment The one mechanism for this forms the basis of holism described in this book and is the evolution of reduced interactive costs between interactors DARWIN's 14 species of finches [2: ] are an example of this They evolved from a single species of ground-dwelling, seed-eating finch [2: back to human evolution ]; [2: back to Argument ]; [2: back to human evolution introduction ]
Evolutionary divergence by the members of a single phylogenetic line into a number of distinctive types or adaptive forms (D)
