- The evolution of a larger brain gave some
early humans a better chance of survival.
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
- 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.
