Similarly, Matthew ^ has suggested that most placental mammals bear evidence of descent from primitive arboreal ancestors. Similarly, in the case of the teeth, insectivorous and omnivorous types appear to be more central and ancient than either the exclusively carnivo- rous or herbivorous types. Thus the extremes of carnivorous adaptation, as in the case of the cats, of omnivorous adaptation, as in the case of the bears, of herbivorous adaptation, as in the case of the horses, or myrme- cophagous adaptation, as in the case of the anteaters, are all secondary. ^ Matthew, W.
