Final answer:
The new species of great ape discovered, named Pongo tapanuliensis, closely resembles the orangutan and was found in the Batang Toru forest in Sumatra.
Step-by-step explanation:
Recently, a new species of great ape was discovered and has been classified as closely resembling the orangutan. Named Pongo tapanuliensis, this third orangutan species was reported in 2017 from the Batang Toru forest in Sumatra. These great apes share many features with their relatives, including being arboreal and exhibiting significant size differences between males and females, with males having distinctive cheek and throat pouches when mature. Similar to other orangutan species native to Indonesia—the Bornean (P. pygmaeus) and Sumatran orangutans (P. abelii)—the Pongo tapanuliensis primarily feeds on fruits.
