| Adriaan Kortlandtb: Rotterdam, Netherlands, Jan 25, 1918 d: Amsterdam, Netherlands, Oct 18, 2009 Prof. Dr. Adriaan Kortlandt was a Dutch ethologist.
He was famous for his work on displacement activities and the hierarchy of instincts. Already in the thirties he realised the common characteristics between instincts in humans and other animals. In one of his experiments in Western Africa he exposed a stuffed panther with an electronic moving head to chimpanzees, who attacked it with sticks, thus illustrating to which extent early man could have kept wild animals at bay even before spears and other weapons were invented.
He also was the author of the "Rift Valley theory", better known under the name given by French paleoanthropologist Yves Coppens: "East Side Story".
Behind their lively, searching eyes one senses a doubting, a contemplative personality, always trying to make sense out of a puzzling world. Once I saw a chimpanzee gaze at a particularly beautiful sunset for a full 15 minutes, watching the changing colors and then retire to the forest without picking a pawpaw for supper. |
