When a group of … In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches. Starting with a single ancestor, this process results in the speciation and phenotypic adaptatio…

WebAdaptive radiations have recently become the focus of studies in conservation biology because they are frequently, particularly on islands, associated with high frequencies of endemism. As a corollary to the high endemism, many of the species that make up an adaptive radiation are often very rare and are characterized by very high extinction rates. WebJan 25, 2024 · The major causes which can trigger adaptive radiation are: 1. Ecological Opportunities – The ecological opportunities that act as the trigger of adaptive radiation … WebAn adaptive radiation is a burst of evolution, creating several new species out of a single parent species. As when we discussed species richness, it is useful here to think of uninhabited "islands" of habitat, though in this case, the islands merely need to be uninhabited by the species in question. A population of given species, which we'll ... sharps motors newbury
