Scientists witnessed an orangutan treating his wounds with medicinal plants, showing human-like behavior

• For the first time, scientists observed a wild animal treating its own wound with a medicinal plant.
• A Sumatran orangutan, chewed up liana leaves and applied them to his wound. It healed in five days.
• This never-before-seen behavior goes to show just how similar we are to our primate cousins.

Rakus the orangutan seems to have a surprisingly decent grasp on first-aid.

He lives in Gunung Leuser National Park in South Aceh, Indonesia, where scientists from the Institute of Animal Behavior meticulously observe animals like Rakus, documenting their activities every two minutes.
