Much is said by evolutionists about the giraffe’s neck
providing it with an advantage of being able to munch
on tree leaves (an unexploited niche), but the claim that
giraffes exploited an empty niche is an incorrect, ad-hoc
explanation. Gould asks if such a habit is so beneficial,
why haven’t many other animals (such as antelopes) also
evolved the same ability?7
It could be argued just as easily
that giraffes with shorter necks were much more apt to
survive because most foliage in the part of Africa where
they live is near the ground, and for this reason it would be
a decided survival advantage to be closer to the more plentiful
ground vegetation compared to the comparatively rarer
acacia tree leaves. Thus, being able to reach the heights
of trees is not necessarily a survival factor.15 It is for this
reason that Hitching concludes the Darwinism explanation
to be mere ‘post-hoc speculation’.21
