Going to the Dogs Some scientists acquired their fascination with dogs directly, but Hare's grew out of his research on chimpanzee cognition in the late 1990s, when he was part of a team of primatologists led by Michael Tomasello, now at Max Planck. A chimp can follow the gaze of other chimps and figure out what they can and cannot see. That's a skill that seems to be limited to great apes and humans. Tomasello and his team wondered if such a rare ability extended to hand gestures and tested chimps to see if they could understand pointing...
...apparent explanation for these results was that pointing--and the social smarts behind it--required a humans-only level of intelligence and evolved in our ancestors only after they branched off from the ancestors of chimpanzees some 7 million years ago. When Tomasello suggested this idea to Hare, however, Hare demurred. "I said, 'Um, Mike, I think my dogs can do that,'" Hare recalls...
...Hare's later research revealed that while chimps and even wolves lack an innate ability to understand what pointing means, dogs come by the knowledge naturally. They're not limited to reading hands and fingers alone. Dogs understand what Hare means if he points with his foot or sets a piece of wood on top of a container with food inside. Even puppies understand, which means it can't be a skill they need to learn. "This is something that dogs just do," says Hare...
Foxy Dogs To understand how dogs evolved this skill, Hare traveled to Siberia. In the 1950s, Soviet scientists set up an experiment on a farm outside the city of Novosibirsk to understand how animals were domesticated. They decided to study foxes, which are closely related to wolves and dogs...
More than 40 generations of foxes have now been bred in Novosibirsk, and the results speak for themselves. The foxes that the scientists bred selectively have become remarkably doglike. They will affectionately run up to people and even wag their tails. In 2003, Hare traveled to Novosibirsk and ran his pointing test on baby foxes. The ordinary ones failed miserably. As for the doglike ones, "they did just as well as puppies right out of the box," Hare says. As the animals were bred for their affability, a new side of their social intelligence was apparently awakened...
