The study also found that orangutans evolved at a slower pace than both chimpanzees and humans. [24] A 2017 genome study found that the Bornean and Tapanuli orangutans diverged from Sumatran orangutans about 3.4 mya, and from each other around 2.4 mya.
Orangutans are rarely, if ever, found south of the Simpang Kanan River on Sumatra's west side or south of the Asahan River on the east side. The Pakpak Barat population in particular is the only Sumatran population predicted to be able to sustain orangutans in the long run, given the current effects of habitat displacement and human impact.

The Hominidae (/ h ɒ ˈ m ɪ n ɪ d iː /), whose members are known as the great apes [note 1] or hominids (/ ˈ h ɒ m ɪ n ɪ d z /), are a taxonomic family of primates that includes eight extant species in four genera: Pongo (the Bornean, Sumatran and Tapanuli orangutan); Gorilla (the eastern and western gorilla); Pan (the chimpanzee and the bonobo); and Homo, of which only modern humans ...
The orangutan taxon is now known to be paraphyletic to other (African) hominids. The orangutans are the only surviving species of the subfamily Ponginae , which genetically diverged from the other hominids ( gorillas , chimpanzees and humans ) between 19.3 and 15.7 million years ago.
Sharks k*ll an average of 5 people per year while cows k*ll an average of 22 people per year. In fact, humans are more deadly to sharks than they are to humans. Humans k*ll about 100 million ...
Recently, most non-human theory of mind research has focused on monkeys and great apes, who are of most interest in the study of the evolution of human social cognition. Research can be categorized in to three subsections of theory of mind: attribution of intentions, attribution of knowledge (and perception), and attribution of belief.

A wounded orangutan was seen self-medicating with a plant known to relieve pain. It's the first time an animal has been observed applying medicine to a skin injury.
