Not only is there great news about a new species of orangutan but the article in Nature announcing it quite casually shows how different strands of science all confirm current scientific understanding of evolution.
Firstly, the newly discovered orangutan (Pongo tapanuliensis).
Well, it's not exactly newly discovered so much as newly identified as a new species. It was first reported by western scientists about 50 years ago when they heard rumours of a population of orangutans living in a the Batang Toru forest in a remote part of the island of western Sumatra. However, it was not until anthropologist Erik Meijaard, that discovered the paper in the mid-1990s that scientists actually went looking for the population. They found the remains of a female, evidence of nests and a male killed by local people in 2013. From these, it was possible, using genetic evidence, to show not only that this was a new species, but how it relates to the other orangutans.
