Discuss the development of mammals of the order Carnivora. What will be an ideal response?
Although the diets of members of the order Carnivora differ greatly, they all eat meat to a lesser
or greater degree. Some of these animals are omnivores, whereas others rarely eat anything but
meat. Most of these animals have well-developed, sharp, pointed canine teeth and specialized
shearing teeth called carnassials. Two distinct groups developed in the Paleocene: the creodonts
and the miacids. Some of the animals in this order, including seals, sea lions, and walruses, have
adapted to the marine environment.
