Fill in the Blanks Compare the following mammal skulls and decide whether their teeth shapes are generally sharp, flat, or intermediate. Bobcat: Fox:Pig:Sheep:   Fill in the Blanks Based on their teeth shape and dental formulas, state whether each of these mammals are herbivores, carnivores, or omnivores. Bobcat:Fox:Pig:Sheep: Review the forelimb skeletal anatomy figure in your reading exercise (Figure 8.4). Look at the types of bones and the number of bones found in each tetrapod forelimb. Limbs with digits are homologous for tetrapods. Create a hypothesis explaining what bones the common ancestor of tetrapods probably possessed. Based on similarities among forelimbs, what bones did the common ancestor of tetrapods probably possess? In your answer, refer to the bones and how they are connected to each other.

Compare a Male Baboon to a Male Human. Compare the Articulated Foot, the Coccyx/Sacrum/Os Coxae, and the Craniums. Describe similarities and differences. Could you identify the species if you came upon a skull of one or the other? How?
