- 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.
