Faunal evolution and radiation of the endemic deer of the Pleistocene of Crete. The authors give a review of the Pleistocene fauna of Crete and its biostratigraphy. They present five possible models of the radiation of the many different forms of Cretan deer which are known: 1. One immigration and one evolutionary line. (fig. 6) 2. Two immigrations and two evolutionary lines. (fig. 7) 3. One immigration and one radiation. (fig. 8) 4. Two immigrations and two radiations. (fig. 9) 5. More than two immigrations. (fig. 10) It is concluded that model 4 is the most plausible.
