To drink, giraffes have to lower their heads and spread their front legs wide apart to reach the ground.<ref>''Amazing animals: Giraffe'' [http://www.bbc.co.uk/nature/reallywild/amazing/giraffe.shtml Science and nature: Animals] BBC</ref> | + | The giraffe feeds from tall trees, particularly [[Acacia]] and [[Commiphora]].

| | According to today's best giraffe researchers, ''no'' [[fossil]] links that could demonstrate the gradual [[evolution]] of the long-necked giraffe from the short-necked giraffe exist. Some [[Paleontology|paleontologists]] postulate a "neck elongation macromutation" to explain the origin of the long-necked giraffe. [[Richard Dawkins]] also claims the origin of the long-necked giraffe is due to macromutation. Wolf-Ekkehard Lönnig points out: "This exception would naturally be fully unnecessary, if the gradual evolution of the long-necked giraffe could really be reconstructed through fossils, especially since he much prefers the gradualist view. Dawkins draws the okapi, in relation to the Giraffa, nearly twice as large as it really is. In this way, the problem of its evolution (the gap between the two forms) appears only half as large. One may well ask if this technique is useful in the search for truth."<ref>Lönnig, Wolf-Ekkehard [http://www.weloennig.de/Giraffe.pdf "The Evolution of the Long-Necked Giraffe – What Do We Really Know?"] (2006)</ref> | | According to today's best giraffe researchers, ''no'' [[fossil]] links that could demonstrate the gradual [[evolution]] of the long-necked giraffe from the short-necked giraffe exist.
