For this reason, neither the medium ground finch nor the cactus finch has stayed morphologically the same over the course of the experiment. This species has diet overlap with the medium ground finch (G. fortis), so they are potential competitors. There was a flood! Give at least 2 reasons. Complete your free account to request a guide.
