The Giraffe is perhaps one of the most iconic species of Africa and to the mysteries and intrigue that lie within the confines of evolution. The purpose of this paper is to explain how this wonderful, iconic organism has evolved physiologically to be suited to its’ environment. In this paper we will be discussing the elements that best describe its’ evolutionary progress.

Being even-toed means just that, they have an even number of toes on each foot. Relatives and family members of the Artiodactyla include most types of deer and antelopes, and also include cattle, sheep, and goats. This also means that many of the Ungulates develop horns or antlers.

The Giraffe and the Okapi are the only two, and Giraffes are the tallest mammals in the world. “Both are tall animals that browse on vegetation; today giraffes occur only in Africa and south of the Sahara, although they formerly live in North Africa, too.” (Bernabeo, 2010) Okapis are not squarely spotted such as the giraffe; instead they have a long brown neck and...
