A brand new species of frizzy-haired orangutans has been found within the distant jungles of Indonesia. With a inhabitants of solely 800, the newly named Tapanuli orangutan is now the world’s most endangered nice ape.
Researchers discovered the remoted primate group within the northern Batang Toru forest on the Indonesian island of Sumatra, in response to a examine revealed Thursday within the journal Current Biology.
“This new species is as old as the earliest of our own direct ancestors,” mentioned Erik Meijaard, a conservation scientist on the Australian National University (ANU) who was concerned within the badysis.
“It has evolved over some 3 million years to quietly adapt to the specific conditions in this part of the Asian tropics.”
Scientists say the brand new species has smaller heads and frizzier orange fur than different orangutans.
Until just lately, solely two genetically distinct varieties of orangutan had been recognized: the Bornean orangutan (Pongo pygmaeus) and the Sumatran orangutan (Pongo abelii). It was solely after figuring out key variations within the tooth, cranium, DNA, food regimen and calls of the Tapanuli orangutan (Pongo tapanuliensis) that the worldwide group concluded that they had discovered a singular species.
“The differences are very subtle, not easily observable to the naked eye,” Professor Michael Kruetzen of the University of Zurich, one of many researchers, advised Reuters.
Frizzy hair and a moustache
Researchers from ANU really occurred upon the inhabitants of apes in 1997 however didn’t think about them to be a separate species till they bought the possibility to look at a skeleton in 2013.
The Tapanuli orangutan bears an in depth resemblance to its Bornean and Sumatran cousins, however shut observers could discover that it has a smaller head, barely frizzier cinnamon-colored fur, and a “prominent moustache,” the scientists wrote.
They imagine the three varieties of orangutans share a standard ancestor however started to diverge into completely different species about three.four million years in the past.
Species on the brink
There are solely believed to be round 800 Tapanuli orangutans left. That makes it probably the most endangered nice ape on this planet, the researchers wrote.
Like the opposite current orangutan species, the Tapanuli group is very susceptible and faces threats from forest clearance, mining, unlawful logging and poachers, in addition to a deliberate hydroelectric dam that might probably flood as much as eight% of its habitat.
“If steps are not taken quickly to reduce current and future threats to conserve every last remaining bit of forest, we may see the discovery and extinction of a great ape species within our lifetime,” the scientists mentioned.
Both Sumatran and Bornean orangutans are listed as critically endangered by the International Union for Conservation of Nature (IUCN).
