In your primate anatomy lab, you are shown the mandible (lower jawbone) of a species of primate. While looking at the teeth you notice a large space between the canine and first premolar. In your lab book you note that this A. Is likely the lower jaw of a human, due to the potential presence of a canine-premolar honing complex B. May be a species of Old World monkey or ape, as the space in the teeth of the mandible suggests the presence of a canine-premolar honing complex C. Is likely the lower jaw of a human, given the presence of a nonhoning chewing complex D. May be a species of Old World monkey or ape, as the space in the teeth suggests the presence of a nonhoning chewing complex

From the following 5 characters, characterise at least 2 key features of the dinosaur teeth provided and use it to determine whether each dinosaur is a carnivore or a herbivore. Write the supporting characteristics out in full but also give the associated character number and its state e.g., denticles absent, 4(0). 1. Tooth shape: (0) Cylindrical [inconclusive] (1) Conical [carnivore] (2) Low and broad [herbivore] 2. Tooth curvature: (0) Straight [inconclusive] (1) Recurved [carnivore] 3. Tooth top: (0) Flat [herbivore] (1) Single sharp cusp [carnivore] (2) Multiple sharp cusp [herbivore] (3) Single rounded cusp [inconclusive] 4. Denticles (serrations): (0) Absent [inconclusive] (1) 'Coarse', few in number and very large [herbivore] (2) 'Fine', many and relatively small [carnivore] 5. Constriction between top and base of tooth (0) Absent or weak. Constriction occupies >85% of largest width [inconclusive] (1) Well-developed. Construction occupying <85% of largest width [herbivore]…

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.

Humans do not exhibit a lot of physical variation in their skeletons.    A. True B. False
