The elephants Byrne and Smet tested are used to take tourists on elephant-back rides in southern Africa. They were trained to follow vocal commands only, never gestures. Smet recorded the behavior of the elephants’ handlers over several months and found they never pointed their arms for the elephants. What’s more, the elephants’ ability to understand human pointing did not vary with how long they had lived with people, nor with whether they were captive-born or wild-born. “If they have learned to follow pointing from their past experiences, it’s mystery when and how,” Byrne says. “Rather, it seems they do it naturally.” |
