Pictorial diagram of Adelops populations movements in the southeastern United States in response to climatic changes in the Pleistocene. This model uses fluctuating Pleistocene climates as a mechanism to introduce the preadapted montane ancestors to cave areas and caves and then to isolate them there. The isolation permitted the development of troglobitic species, which seemingly later underwent range adjustments by overland dispersal in the Wisconsin. Further explanation in text and with Fig. 214. Application of names is a fit of the model to the classical divisions of the continental North American Pleistocene. Times of glacials and interglacials from Emi- liani (1971), based on oceanic sediments. This application is controversial, and simplistic. Its effect here is to perhaps make too rapid the speciational and adaptational events. Biologists often do not appreciate the fact that, for purposes of interpreting evolutionary events and biogeography in a framework of Pleistocene history, the use of a time scale matched with climatic conditions and classical Pleistocene division names preceding 150,000 years BP is presently very questionable (see Broecker, 1965)..
