1. What anatomical features tell us that humans are vertebrates and mammals? Vertebrates have a nerve cord that is protected by a vertebral column, we also have hair and mammary glands which classifies us, as humans, to be mammals also.

2. How do humans differ from other mammals, including apes? Humans differ from other mammals because they have a more highly developed brain, completely upright stance, creative language and ability to use a wide variety of tools.

From Chapter 22 pages 475-477

3. How are humans classified? From Domain to Species. The binomial name of an organism gives its genus and species. Organisms in the same domain have only general characteristics in common; those in the same genus have quite specific characteristics in common. 4. What are the characteristics of primates? Primates have mobile limbs; grasping hands; a flattened face, binocular vision, a large, complex brain; and reduced reproductive rate.

5. What major differences exist between the chimpanzee skeleton and the human skeleton? Humans adapted for an upright stance with the spine existing inferior to the center of the skull in the midline of the body, this enables humans to walk long distances and run with less chance of injury.
