Now they are classified in a separate order, Scandentia
(Martin, 1990), placed between insectivores and primates.
The eutherians include representatives of five orders that are presumed to have separated near the basal radiation of eutherians [ILLUSTRATION FOR FIGURE 2 OMITTED], with four of the orders representing an unresolved tetrachotomy: the Artiodactyla, Carnivora, Scandentia
, and Rodentia (Novacek and Wyss 1986 and references therein; Novacek 1990).
The orders include Insectivora, Scandentia
, Chiroptera, Pholidota, Primates, Rodentia, Lagomorpha, Creodonta, Carnivora, Tubulidentata, Proboscidea, Artiodactyla, and Perissodactyla.
