1.Part of the great ape family, two classifications of Asian apes=gibbons and orangutan ,
2They are unique in the fact that they only come from asia where as the other three apes( gorilla , chimpanzee and bonobo) come from africa.
3Exclusively live in Borneo and Sumatra
4Two classes of orangutan- in regards to where they live 1. Bornean from borneo and the Sumatran from Sumatra, they have different physical traits also ( they share the same traits such as ……..males and females look different, long shaggy hair, male is larger up to 190 pounds, grows check pads and beards, female is almost half the size, fist walkers vs knuckle walkers, mother infant is the primary social group, males are solitary meeting only to mate, this is thought because evolved due to food shortage, slowest life history meaning slow to reproduce every 7-8 years and takes a long time to grow up baby stays with mother for at least the first 5 years. Age span is roughly 45 years in the wild.
Borneo is darker brown fur and males have larger check pads
Sumatra has a red orange coat white around mouth and belly and a better throat beard

How closely related we are Orangutan is closely related to human however chimpanzees sharing 98% of the same dna making them even more closely related. . or are they? New study finds that physical resemblance may be closer sharing 28 unique characteristics when only sharing 2 with chimps and 7 with gorilla. http://news.nationalgeographic.com/news/2009/06/090623-humans-chimps-related.html)
