The notes should be seen as an outline, not as a replacement for the lecture itself. Dr Tim Benton. The history of the ideas. The phenotype is the expression of a gene - but the expression is not limited to morphology, or even behaviour. Phenotpyes can be extended beyond the body housing the genotype.
Evolution is like that - illustrated with info on the battle of the sexes.
Neutral evolution Evolution is not just about natural selection. Some evolutionary change occurs without selection, by random genetic drift. This is especially likely if a population is small and the mutation has no phenotypic effect - i.e. it is neutral.
