What an amazing observation. Higher primate demonstrating complex thought processes. Sorry for the non-political post but this kinda blew me away. In a first, an orangutan was seen treating his wound with a medicinal plant Researchers heard a fight between male orangutans in the treetops of a rainforest in Sumatra, Indonesia; a day later, they spotted Rakus sporting a pink wound below his right eyelid. Over the next several days, researchers followed Rakus at a distance — and saw something so surprising they wound up reporting it in great detail in the journal Scientific Reports. According to their study, published Thursday, Rakus was observed repeatedly chewing on the leaves of a particular liana plant over several days. The climbing vine is not a typical food for orangutans, but it is known to humans as a pain reliever.
