Researchers hypothesized that on daphne major


2.) After the drought if 1977, researchers hypothesized that on Daphne Major, medium ground finches with large, deep peaks survived better than those with smaller beaks did because they could more easily crack and eat tough Tribulus cistoides fruits. If this hypothesis true, what would you expect to observe if a population of these medium ground finches colonizes a nearby island where Tribulus cistoides is the primary available food in all years? Assume that (1) even the survivors of the1977 drought sometimes had difficulty cracking the tough Tribulus fruits and would eat other seeds when offered a choice; and (2) food availability is the primary limit on finch fitness on this new island.
