B3 Life on Earth

How did humans evolve?

  • The evolution of a larger brain gave some early humans a better chance of survival.
  • Human evolution involves a common ancestor, divergence of hominid species and extinction of all but one of these species.
    When provided with additional information about human evolution you should be able to:
    • draw valid conclusions about the implications of given data for a given theory;
    • recognise that an observation that agrees with a prediction increases confidence in the explanation that was used to make the prediction, but does not prove it is correct.
  • An observation that disagrees with a prediction indicates that either the observation or the prediction is wrong, and that this may decrease our confidence in the explanation.
