New species arise as a result of: isolation – two populations of a species become separated genetic variation – each population has a wide range of alleles that control their characteristics natural selection – in each population, the alleles that control the characteristics help the organism to survive are selected speciation – the populations become so different that successful interbreeding is no longer possible.

What is the difficulty in applying this definition to species such as bacteria? If a mutation were to affect the ability of a group of individuals to perform elements of a courtship display correctly, suggest what this would mean for them and why it might be significant in terms of speciation?
