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.
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 ...
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.

Bornean orangutan are more solitary than their Sumatran relatives. Two or three orangutans with overlapping territories may interact, but only for short periods of time. [23] Although orangutans are not territorial, adult males will display threatening behaviors upon meeting other males, and only socialize with females to mate. [24]
The phylogenetic split of Hominidae into the subfamilies Homininae and Ponginae is dated to the middle Miocene, roughly 18 to 14 million years ago.This split is also referenced as the "orangutan–human last common ancestor" by Jeffrey H. Schwartz, professor of anthropology at the University of Pittsburgh School of Arts and Sciences, and John Grehan, director of science at the Buffalo Museum.
Humans and orangutans are both unique to a bipedal reactive adaptation when climbing on thin branches, in which they have increased hip and knee extension in relation to the diameter of the branch, which can increase an arboreal feeding range and can be attributed to a convergent evolution of bipedalism evolving in arboreal environments.

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 ...
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.
