The remote population of orangutans in the Batang Toru forest had only been discovered in 1997. But it was Matthew Nowak, a conservationist with the Sumatran Orangutan Conservation Program, who found the first evidence that it could be a distinct species in 2013: specifically, the bones of a male that had been injured by local humans and later died were distinctly different from other orangutan species.
