Adaptive radiation describes the rapid speciation of a single or a few species to fill many ecological niches.
adaptive radiation
The evolution from a relatively primitive and unspecialized type of organism to several divergent forms specialized to fit numerous distinct and diverse ways of life, ...
These finches, better known as 'Darwin's Finches' illustrated adaptive radiation. This is where species all deriving from a common ancestor have over time successfully adapted to their environment via natural selection.
Adaptive radiation. The evolution of new species or sub- species to fill unoccupied ecological niches.
Aerobe. A microorganism that grows in the presence of oxygen. See Anaerobe.
adaptive radiation The development of a variety of species from a single ancestral form; occurs when a new habitat becomes available to a population.
Adaptive Radiation the process of a species spreading into and making use of a new environment
(ad = to‚ toward; apt = fasten‚ adjust‚ fix; radia = spoke‚ ray‚ radius) ...
adaptive radiation
The emergence of numerous species from a common ancestor introduced into an environment, presenting a diversity of new opportunities and problems.

Adaptive Radiation
The process described above can occur over and over. In the case of Darwin's finches, it must have been repeated a number of times forming new species that gradually divided the available habitats between them.
Adaptive radiation
Evolutionary diversification of a generalized ancestral form with production of a number of specialized forms by adaptation. See cladogenesis.

Adaptive radiation is the notion that when a species enters a new ecological zone, for example, it has the opportunity to exploit this new zone in many different ways, and it's very true that once a new group of animals has become established, ...
adaptive radiation Evolutionary diversification that produces numerous ecologically disparate lineages from a single ancestral one, especially when this diversification occurs within a short interval of geological time.
Marsupials were once widespread, but today are dominant only in Australia, where they underwent adaptive radiation in the absence of placental mammals. The Metatheria contains 272 species classified in several orders.
He proposed that the ancestral finches who came to the islands, found no competitors or predators and that through adaptive radiation they came to occupy the variety of ecological niches on the islands.

Cladogenesis
Process of evolutionary branching of basic forms into specialized forms by differentiation, specialization and adaptation. See adaptive radiation.
Stasigenesis
Phylogenetic stop, stabilization and conservation.
radiation -- Event of rapid cladogenesis, believed to occur under conditions where a new feature permits a lineage to move into a new niche or new habitat, and is then called an adaptive radiation.
Adaptive radiation: evolutionary divergence of members of a single phyletic line into many different niches. Allele: one of two or more different chemical codes possible for a given gene. Offer variation in a given trait.
