Comparative anatomical study of the carotid circulation in gundis, with implications for their evolutionary history.
The carotid circulation pattern in gundis (Ctenodactylidae) is examined and compared with that of typical members of the classical rodent suborders. On this basis their probable phylogenetic relationships and systematic position are discussed. Together with other recent investigations, the unique pattern of cephalic arterial supply emphasizes the isolated position of the ctenodactylids.
