And the proof of macroevolution lies in microevolution. As giraffes get longer necks, some move on and this is no longer useful in a new climate with smaller trees, so they get shorter necks. Now let's consider them moving to a boggy climate with these small trees. They get stubbier legs, with more surface area touching the ground. Perhaps webbed feet develop. At this point they have changed so much so as they are hardly giraffes anymore, so after many, many, billions of years, they become so different they are a different species. The example I gave here is highly hypothetical, so please feel free to point out discrepancies in it.
