Asia: omomyid-adapid primates: holarctic distribution (north america and eurasia, marsupials: first radiation: north america , second radiation south america , third radiation: australia, the order carnivora is traditionally divided into two major suborders. Set of specialized teeth that have a carnassial pair and are used for shearing and shredding meat. Carnassial pair = pair of teeth used for slicing meat, involves the top 4th pre molar and the bottom 1st molar. Not all members have carnassial teeth: the evolution of teeth in the xenarthrans (also known as "edentates") followed two, very different pathways. Describe these evolutionary trends, naming the families involved. Myrmecophagidae evolved to have no teeth (anteaters) Pleistocene extinction: when referring to mammals of the order insectivora, why do i prefer that we use the term. Not all insectivore are insectivores (not all eat insects: provide two possible explanations for why the fossil record of early bats is so poor.
