Help with this genetics problem please?
You find evidence for strong directional natural selection over 10 generations
on tongue length in a moth species (increasing length across generations) that
feeds on the nectar produced in long nectar tubes of a particular plant species.
You find that there has been no change in the mean or variance in nectar tube
length in the plant species. Has co-evolution occurred? If so, why or if not why
not and what type of evolution, if any, has occurred?

co-evolution means that 2 or more organisms simultaneously evolve in response to the selective pressure created by the other.
think of the running speed of a cheetah and antelope.
If your flower tube was also getting longer (or shorter) that would be evidence to suggest co-evolution. of course there could be alternative causes for that change.
