Biology adaptive radiation
WebThe evolution of hyposdonty represents a key adaptation involved in many ungulate adaptive radiations. Methods: To test whether hypsodont ungulates have potentially wider or narrower niche breadth in respect to their non-hypsodont, pre-adaptive radiation ancestors, I analysed δ 13 C values in the tooth enamel of Pleistocene ungulates as a ... WebIntroduction. Since Darwin (1859) first remarked on the diversity of island species, evolutionary biologists have speculated on the sequence of events that lead to diversification and adaptive radiation following access to new environments. Most theories of adaptive radiation, including Simpson’s (1949, 1953) and Schluter’s (2000), suppose that the …
