Wild chimpanzees have been observed self-medicating their wounds with plants, providing medical aid to other chimps and even removing others from snares left by human hunters, new research suggests. The behaviours—which are documented in a new study published in the journal Frontiers in Evolution and Ecology recently—provide new clues about the origin of medical care in humans. The study combines historical data and about eight months of new observations, including many captured on video and in photos. It provides added evidence that our closest living relatives will chew plants and apply makeshift poultices to wounds, clean other animals’ wounds by licking them, and use leaves for a hygienic scrub after sex or defaecation. Chimps were also seen pressing wounds and dabbing medicinal leaves to wounds.
