Animals respond to injury in many ways. So far, evidence for animals tending wounds with biologically active materials is rare. Yet, a recent study of an orangutan treating a wound with a medicinal plant provides a promising lead.
Chimpanzees, for example, are known to lick their wounds and sometimes press leaves onto them, but these behaviours are still only partly understood. We still do not know how often these actions occur, whether they are deliberate, or how inventive chimpanzees can be when responding to wounds.
Recent field observations in Uganda, east Africa, are now revealing intriguing insights into how these animals cope with wounds.
