It is a demonstrated fact (you can even see a video of the dissection showing the path of this nerve is more than 4 meters longer than it need be as it still passes under the aorta and collar bone as the giraffes evolved longer necks of millions of years). Here is the creationist’s attempt to cope with this embarrassing fact: … giraffe fossils were laid down in depositional events after the global Flood, we might conclude that the fossil record of giraffes represents post-Flood intrabaraminic (‘within-kind’) diversification. Furthermore, recognizing that the earliest known Cenozoic giraffids (as well as the only other living member of that family, the okapi) possess short necks, we might well infer that the ancestral giraffe on the ark was short-necked and subsequently diversified into longer-necked forms, …” From: http://thenewcreationism.wordpress.com/2010/01/05/musings-on-loopy-laryngeal-nerves/ They did not choose the alternative that God was a very stupid designer. Instead suggest that in the short time since the biblical flood the giraffes grew (by adaptation? To reach higher leaves?) their long necks; yet say that supporters of evolution are wrong as we don’t see significant changes from one generation to the next.
