EUREKALERT, ANNA F. SMET AND RICHARD W. BYRNETo date, the only nonhuman animals that have demonstrated an ability to understand pointing are dogs. Even chimpanzees, man’s closest genetic relatives, do not seem to understand the gesture. But research published this week (October 10) in Current Biology provides evidence that African elephants can understand a human’s point—about as well as a human toddler.

Scientists Anna Smet and Richard Byrne of the University of St. Andrews in the United Kingdom worked with a group of eleven captive elephants, which had been trained to give humans rides at a safari park in Zimbabwe. Smet hid food in one of two five-gallon buckets and then indicated to the elephants where the food was by pointing and looking back and forth from the bucket containing the food to the elephant until it made a choice. The elephants chose the correct bucket on average 67.5 percent of the time; human 12-month-olds have an average success rate of about 73 percent. In control trials, where Smet stood between the buckets without gesturing, the elephants chose the bucket containing the food only 46.7 percent of ...
