http://www.cnn.com/2006/TECH/science/07/14/darwin.finches.ap/index.html?eref=yahoo I am not quite sure wether I understand what they mean. Do they argue that G. fortis with larger beaks were able to produce small-beaked G.Fortis as offspring in a critical time where the large-beaked G.fortis had no more chance to survive? Or do they simply mean that small and large-beaked G.fortis lived at the same time and the large-beaked ones died out because of their competitors? Because this would be the same as with the peppered moths. If this is what they mean then I don't understand the fuss about this. If there have not been any small-beaked G.fortis before and suddenly the large-beaked G.fortis get small-beaked G.fortis as offspring then I would say we have a problem because this would mean that the G.fortis were somehow able to react to a situation and change their genes somehow, but I cannot really imagine that this is possible, how should this work? Did the large-beaked G.fortis realize that he was dying out and then thought to himself: "I gotta do something real fast otherwise my offspring will die out." And then his genes changed in order to produce short-beaked G.fortis. This sounds pretty absurd to me.
