  • This is the tap a newly orangutan, a species new to science.

  • Early DNA analysis suggested these animals were peculiar.

  • Years of painstaking genetic comparisons enabled scientists to reconstruct the animals.

  • Evolutionary history.

  • It's an amazing breakthrough.

  • I think the remote mountain forests of Sumatra are home to some of our closest ape relatives on a small population here, first discovered just 20 years ago, has been hiding a scientific secret.

  • This is the tap a newly orangutan, a species new to science.

  • Until now, it was thought that they were just two distinct species of around town Sumatran and Bornean, like this big male here.

  • But this new study shows that there are actually three.

  • A tiny population has been hidden away and isolated by hundreds of thousands of years of evolution.

  • Early DNA analysis suggested these animals work peculiar compared to the other Sumatran apes.

  • So scientists embarked on a detailed study examining what they ate and the unique calls this is.

  • The years of painstaking genetic comparisons enabled scientists to reconstruct the animals evolutionary history.

  • The final piece of the puzzle, though, was tiny but consistent differences between the Sumatran and this that tap a newly orangutan school.

  • It's an amazing breakthrough.

  • I think there's only seven.

  • If we exclude ourselves off great ape species.

  • So adding one to that very small list, it's this spectacular.

  • With just 800 individuals, this species will go straight onto the critically endangered list.

  • Logging, mining and plans for a hydro electric dam already pose a threat to its habitat.

  • The hope is that adding this ape to the biology textbooks will help to ensure its survival.

This is the tap a newly orangutan, a species new to science.
