Practise defining evolution as inherited change over generations and explaining how mutation, selection and altered allele frequencies can produce new species.
Variation exists in populations of a species and this may provide the opportunity for evolution to occur.
Outline the theory of evolution.
any three from:
1 formation of new species from, pre-existing species / common ancestor ;
2 change in, characteristics / phenotypes ;
3 over, time / generations ;
4 natural selection ;
5 changes in, gene pools / allele frequencies
or genetic drift ;
