even though the long neck of the giraffe would appear to be a stunning example of the power of natural selection, in the first edition of on the origin of species by means of natural selection darwin focused on a very different part of the mammal’s anatomy; it’s tail. giraffe pictures wallpaper. the giraffe’s tail, although appearing to be an organ of trifling importance, was an excellent flyswatter which has probably played at least some role in helping individuals resist the attacks of biting insects. giraffe pictures wallpaper. from the beautiful intricacy of the vertebrate eye to the relative crudeness of the giraffe’s tail, natural selection could be consistently applied to explain the origins of adaptations. according to mivart, the giraffe was a perfect example of natural selection’s inefficacy.

assume that a giraffe’s long-neck truly was an adaptation for reaching high foliage during droughts which denuded other sources of food. this would be consistent with natural selection, mivart argued, but if droughts truly had favoured the lengthening of the giraffe’s neck then it is surprising that no other herbivores were adapted in the same way. giraffe pictures wallpaper. likewise, the changes which must have occurred between the ancestral and modern giraffe pictures wallpaper must have extended beyond neck length alone. various bits of anatomy and physiology would have had to have carried favourable variations in order for it to even be possible for giraffes to evolve long necks, and these changes which would have increased the mass of the giraffe would have required that it take in even more food under stressed, drought conditions.
