Question

Quizplus · Accepted Answer

When a species invades a new habitat and evolves rapidly into several new species, this is an example of adaptive radiation. This occurs because the species is exposed to new ecological niches and selective pressures, leading to divergent evolution and the creation of multiple new species. Polyploidy refers to a type of mutation involving changes in chromosome number, while divergent and phyletic speciation are more gradual processes that do not necessarily involve rapid evolution into multiple new species.
