第2698期:Wild chimpanzees filmed using forest 'first aid'

In some of the footage researchers have captured, an adult male dabs a wound with a leaf from a plant that's also gathered by local people for medicinal use. Another rather shaky but extraordinary video shows a young female dabbing chewed up plant material onto an injury on her mother's body. This is rare evidence of wild chimps using plants to tend to each other's injuries.在研究人员捕捉到的一些影像中，一只成年雄性黑猩猩用一种植物的一片叶子轻轻擦拭一个伤口。这种植物也是当地人采集的药用植物。在另一段画面十分晃动但非同寻常的视频中，一只年轻的雌性黑猩猩将嚼碎了的植物树叶涂抹在她母亲身上的伤口上。这是野生黑猩猩用植物为彼此疗伤的罕见证据。These animals are some of our closest living relatives. Studying them in the wild gives scientists insight into the origins of our own social behaviour, our communication, and now, how we care for one another.黑猩猩是现存与人类最为接近的亲缘物种之一。在野外研究它们能让科学家深入了解我们人类自身的社会行为和交流方式的起源，以及现在我们关爱他人的方式源自何处。
