Unit 2 – Nonhuman Primate Diversity

Unit 2 – Nonhuman Primate Diversity

Summary:

As members of the Primate order, modern humans share more genetic material with monkeys, lemurs, and apes than with other mammals. In this unit, students will learn about the diversity among nonhuman primates and what research has revealed about primate behavior, communication, and other social interactions.

Professor Talking Points:

  • Modern humans are members of the order Primates and share a large amount of DNA with others in this order, which includes lemurs, lorises, tarsiers, monkeys, and apes.
  • Primates are distinguished by particular physical and behavioral traits: for example, forward-facing eyes, excellent vision, a post-orbital bar, dexterous hands, collarbones, five fingers on the hands and feet, small litters, and larger brains compared to other animals of similar sizes.
  • As Homo sapiens, our closest living relatives are chimpanzees and bonobos.
  • Studies on primate behavior show us what we have in common with other species in our order and where we differ in genetics, anatomy, and behavior.

Student Discussion Questions:

  1. What is the role of the environment in primate diversity?
  2. How does competition with non-primate animals impact primate behavior?
  3. What have you learned about kinship relationships in primate groups? Are there factors that might be more important than social relationships in determining how certain species, such as chimpanzees, interact with one another?
  4. What do the readings say about the nature of primate communication?
  5. Discuss what you have learned about sharing and cooperation among the primate groups you have read about.
