The North American maggot fly diverged into two species because some individuals fed on apples rather than hawthorn trees. Apple fruit mature more quickly than hawthorn fruit, therefore maggot flies that fed on apples also developed more quickly. Pea aphids can feed on alfalfa or red clover; some aphids have higher fitness when eating clover others when eating alfalfa. Host preference can

eventually lead to speciation because A. genetic differences develop. B. lower fitness may result from choosing the wrong host. C. temporal isolation may occur. D. anagenesis may occur. E. genetic differences develop, higher fitness and temporal isolation may occur.
