Darwin's finches on the Galapagos Islands are a model system for the study of adaptive radiation. [10] Today represented by approximately 15 species, Darwin's finches are Galapagos endemics famously adapted for a specialized feeding behavior (although one species, the Cocos finch ( Pinaroloxias inornata ), is not found in the Galapagos but on ...
Seen here is adaptive radiation of finch A (Geospiza magnirostris) into three other species of finches found on the Galapagos Islands. Due to the absence of other species of birds, the finches adapted to new niches.
The silversword alliance, also known as the tarweeds, [1] refers to an adaptive radiation of around 30 species in the composite or sunflower family, Asteraceae. The group is endemic to Hawaii, and is derived from a single immigrant to the islands.
Their great morphological diversity is the result of adaptive radiation in an insular environment. Many have been driven to extinction since the first humans arrived in Hawaii , with extinctions increasing over the last two centuries following European discovery of the islands, with habitat destruction and especially invasive species being the ...
Adaptive radiation is when a single species colonizes an area and rapidly diversifies to fill all of the available niches. A common example is the assemblage of finch species documented by Charles Darwin in the Galapagos Islands. Darwin’s finches exhibited adaptive radiation by evolving different beak sizes to exploit the diversity of seeds ...
Among the endemic insects, the adaptive radiation of the gelechioid moth genus Asymphorodes is remarkable, with most of its 80 or so species known only from the Marquesas. Other Marquesan endemic moths include the strange Clarkeophlebia argentea , the enigmatic Marasmianympha eupselias , and Tessema sensilis which is apparently quite common but ...
Anolis lizards are some of the best examples of both adaptive radiation and convergent evolution.Populations of lizards on isolated islands diverge to occupy separate ecological niches, mostly in terms of the location within the vegetation where they forage (such as in the crown of trees vs. the trunk vs. underlying shrubs).

For example, Albinaria land snails on islands in the Mediterranean [1] and Batrachoseps salamanders from California [2] each include relatively dispersal-limited, and closely related, ecologically similar species often have minimal range overlap, a pattern consistent with allopatric, nonecological speciation.
