THE mode of evolution in the giraffe has been a favourite subject for discussion, Darwin1 wrote “… it has been supposed that all the parts must have been simultaneously modified; and it has
The evolution of the giraffe can be observed from the fossils of their ancestors. http://img01.deviantart.net/20ea/i/2015/023/2/4/giraffids_by_tfprime1114-d8f4i5k.png Descent with modification can be seen in the gradual changes in body shapes of the giraffe’s prehistoric ancestors. The giraffe (Giraffa) is an African artiodactyl mammal , the tallest living terrestrial animal and the largest ruminant . It is traditionally considered to be one species , Giraffa camelopardalis , with nine subspecies . However, the existence of up to nine extant giraffe species has been described, based upon research into the mitochondrial and nuclear DNA , as well as morphological
Some scientists have long presumed today’s giraffe (Giraffa camelopardalis, right), which includes a handful of subspecies scattered throughout sub-Saharan Africa, evolved from an animal that
Summary: As shown in the evolutionary tree (Picture C), giraffes and okapis evolved from a common ancestor, the pre-okapi. This has substantial evidence as the okapi is the only close relative to the giraffe and their skulls, as shown in picture D , are very identical. Lamarck believed that the long necks of giraffes evolved as generations of giraffes reached for ever higher leaves.

The giraffe is the tallest mammal in the world, standing at around 4-5m high, and the tallest giraffes ever recorded have been up to 5.9m. That’s over a meter higher than a double-decker bus. It shouldn’t come as a huge surprise that such a large animal weighs quite a lot as well – up to 1900kg, which is more than most cars! 2020-03-26 · Lamarckism, or the theory of Lamarckian inheritance, is abandoned in modern evolutionary biology. As of 2014, two main hypotheses account for the elongation of the necks of giraffes. One, proposed by Darwin and called the competing browser hypothesis, posits that giraffes evolved long necks to reach food inaccessible to other animals. Call it a tall task: researchers have decoded the genomes of the giraffe and its closest relative, the okapi.

Eventually, they became extinct, but a new species emerged. Every giraffe has a completely unique pattern on its coat. The ancient Greeks and Romans thought the pattern looked a bit leopard-ish on a cameloid body, hence the giraffe's genus name: Camelopardis. The giraffe’s most defining feature, however, is the neck, which can be up to 2.5 m (8 ft) long on its own. The giraffe (Giraffa) is an African artiodactyl mammal, the tallest living terrestrial animal and the largest ruminant.It is traditionally considered to be one species, Giraffa camelopardalis, with nine subspecies. The evolutionary history of the giraffe brings us back to approximately 50 million years ago. An animal similar to antelopes evolved into two species that are extant today.
