Changes

Sexual maturity is reached at age 4-5 years although bulls usually only mate at 8 or more years old. Gestation lasts 15 months, after which a single calf is born, although twins have been recorded very rarely. The female can mate again 5 months after giving birth, and there is no established breeding season. For the first few weeks the calf remains hidden in the shade with the mother returning to it, and later it joins a creche within the herd. Calves grow fast, and are weaned at 18 months, although they start eating solids well before then. Fifty per cent die in their first 6 months, the victims of predators.<ref>''Wildfacts: Giraffe'' [http://www.bbc.co.uk/nature/wildfacts/factfiles/631.shtml Science and Nature: Animals] BBC</ref>

Until recently, there were ''no'' [[fossil]] links that could demonstrate the gradual [[evolution]] of the long-necked giraffe from the short-necked giraffe. But Nikos Solounias of the New York Institute of Technology has described a transitional fossil from the late Miocene and early Pliocene. Its neck was a perfect intermediate between the short-neck ancestors and their long-neck descendants.<ref> http://www.newscientist.com/channel/life/mg19726451.700-evolution-what-missing-link.html Newscientist </ref> 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>
