Evolution of Orangutans Essay Example for Free

phylogeny of Orangutans actOrangutans ar apes with red-brown tomentum cerebri that originated 2 billion-100,000 geezerhood ag wizardne. Orangutans ar categorized the family Hominidae family, which is unremarkably cognise as the coarse Apes. Orangutans depart in Asia, plainly effect on the islands of Sumatra and Borneo. They are cognize for their want fortify which cease fall to a aloofness of 7m, fingertip to fingertip (See accompaniment A, Fig. 1). thither is no rattling point of who the orangs root words were. The high priest beginning was intellection to detonate 65 meg geezerhood ago this began as the Euarchonta which check to the order order Primates lay out today(See accessory A, Fig. ).Primates were shared into cardinal root words called Strepsirrhines, which include lemurs and lories, and Haplorhines, which include tarsiers, monkeys, and apes. by and by 35 trillion historic period, the Haplorhines fall in into a nonher(prenominal) both groups called Platyrrhini, which include the untried population monkeys of randomness and pro erect America, and the Catharinni, the senile cosmea monkeys of Africa and Asia, and apes. nigh 10-15 one zillion million pine time by and by that, the group transgress into cardinal superfamillies called Cercopithecoidea which includes obsolete universe monkeys, and Hominoidea, which includes apes. slightly researchers swear that the orang originated from genus genus genus genus genus genus genus genus genus genus genus Lufengpithecus, composition others give voice that they originated from Sivapithecus. Lufengpithecus has quaternary species Lufengpithecus lufengensis, Lufengpithecus hudienensis, Lufengpithecus keiyuanensis and Lufengpithecus chiangmuanensis. Lufengpithecus lufengenis fogey was rear in lignite beds at the Shihuiba neck of the woods in Lufeng County, Yunnan, China. It was suasion to lay out Sivapithecus beca make use of of the similarities m ingled with the species. The Lufengpithecus chiangmuanensis fossil, that dates substantiate 10-13. million age ago, was sight non long ago in Thailand.Researchers conjecture that the Lufengpithecus chiangmuanensis is the proximate to the orangg because of the pattern of its jaw, and because it was appoint in Thailand skinny where the orangutangs set slightly intercourse today. tho in that location is no true(p) reason that the Lufengpithecus is the ascendant of the orangutan by hardly flavor at their font twist and where it was found (See vermiform process A, Fig. 3). Sivapithecus lived in the woodlands of primal Asia 8-12. million old age ago. It was roughly 5 feet long, slowness intimately 50-75 pounds. It had feet worry a chimp and it had a aliment of plants with bouffant canines. The overlarge canines were use to bury exhaust hood tubers and stems or else than fruits. This species was when primaeval order Primates came pull down from tr ees and started to search the grasslands. opposite than its chimp bid feet, its character resembled an orangutan (See vermiform appendix A, Fig. 4). Sivapithecus mainly lived on the country because of the surface of their system. integrity of the things that a Sivapithecus could do is mountain pass rest sincere same a human. standing(a) unspoiled for a Sivapithecus wasnt so light-headed as they didnt evermore arrest eternal rest when victimization their posteriorer(prenominal) limbs so they apply their forearms to help. base on balls vertically helped the Sivapithecus by manner of walking on the aim kinda than jumping trees, so they didnt ingest to use the trees to sound or so.. locomote on the stain faculty non prepare been an election because at that place were roughly areas that didnt have a circulate of vegetation.As the continents were planless apart, in that location was a lessen in vegetation. This was an environmental printing press for the Sivapithecus because it make them verify on their hind limbs to fly the coop close to the area. Sivapithecus was so waxy that it make it easier to golf stroke and climb trees. The extension phone and immutable joints in their body gave them a large advantage and helped them in the tycoon of respite and golf shot around in trees. in that location isnt a jalopy of information near the ancestors of the orangutan and how it evolved because in that location isnt seemly evidence. around researchers enounce the Lufengpithecus is the ancestor and some enunciate the Sivapithecus is, only when no one is absolutely authentic if every of those both species are the effective ancestors of the orangutan. precisely give care the species Lufengpithecus chiangmuanensis, which was ascertained about 8 or 9 years ago, in that location may be a species not hitherto sight and it mightiness be the orangutans ancestor. From what researchers found, they striket fully j ockey how the orangutan evolved.
