Daily Catalyst- Thursday
  • Information: Bonobos and chimps are genetically equidistant from humans. The traditional model of human sexuality asserts that humans evolved from chimps.
  • Scenario: Chimps are violent and aggressive. They do not pair-bond and copulate just for mating purposes. However, bonobos are kind and friendly. They copulate for a variety of reasons beyond mating and raise their young as a community.
  • Questions:
    • If it’s true that chimps are humans’ direct ancestors, what kinds of behavioral adaptations would have allowed us to evolve?
    • Do you think it’s possible humans evolved their sexuality from bonobos instead of chimps? Explain your reasoning.
    • Most people believe humans are naturally-included toward monogamy, however humans are the only apes that do so. Where do you think this idea came from and do you agree? Explain.
