Summary: The Evolution Of Orangutans
The Evolution of Orangutans
Orangutans are apes with reddish-brown hair that originated 2 million-100,000 years ago. Orangutans are categorized the Hominidae family, which is commonly known as the Great
Apes. Orangutans live in Asia, only found on the islands of Sumatra and Borneo. They are known for their long arms which can reach to a length of 7m, fingertip to fingertip
(See Appendix A, Fig.1). There is no real evidence of who the orangutan’s ancestors were. The primate lineage was thought to start 65 million years ago; this began as the Euarchonta which lead to the primates present today(See Appendix A, Fig.2). Primates were divided into two groups called Strepsirrhines, which included lemurs and lories, and Haplorhines, which included …show more content…
But there is no true evidence that the Lufengpithecus is the ancestor of the orangutan by just looking at their face structure and where it was found (See Appendix A, Fig.3).
Sivapithecus lived in the woodlands of Central Asia 8-12.8 million years ago. It was about 5 feet long, weighing about 50-75 pounds. It had feet like a chimpanzee and it had a diet of plants with large canines. The large canines were used to eat tough tubers and stems rather than fruits. This species was when early primates came down from trees and started to explore the grasslands. Other than it’s chimpanzee like feet, its face resembled an orangutan (See
Appendix A, Fig.4). Sivapithecus mainly lived on the ground because of the size of their body.
One of the things that a Sivapithecus could do is walk standing upright like a human. Standing upright for a Sivapithecus wasn't so easy as they didn't always have balance when using their hind limbs so they used their forearms to help. Walking vertically helped the Sivapithecus by walking on the ground rather than climbing trees, so they didn't need to use the trees to
