  • How do genes get passed from one generation to the next?
    Reproduction
  • The process by which the distribution of traits in a population changes over many generations
    Natural selection

    Evidence
  • A group of individuals born and living at about the same time
    Generation
  • A group of the same type of organism living in the same area
    Population
  • True or False: A population will not go extinct if they do not adapt.
    False
  • When animals change their behavior or appearance in response to changes in the environment
    Adaptation
