Point at a ball and a dog will look at the ball, whereas a cat will probably look at your hand. Dogs seem to have a ready understanding of how human beings direct attention by pointing, and can follow our gestures almost as if they thought the same way we do. Of course, dogs probably aren’t born knowing anything about people. We just carefully train them to look, fetch, and so on. An expert at the Max Plank Institute in Germany, named Michael Tomasello ran a series of tests on dogs, in which they had to find which sealed container had yummy dog food in it. The only hint they got was from a human being who looked at or pointed at the right container. This wasn’t hard for dogs at all. But it was hard for wolves. Wolves that have been raised by people should have had the same success at finding the sealed container, but they didn’t. Even monkeys, which are very smart animals indeed, weren’t as fast at finding the food as dogs. What does this mean? One interpretation is that dogs do have a natural ability to understand forms of human communication. Even nine-week old puppies found the food, suggesting the skill is there before training. Wolves don’t have the skill, suggesting that it has developed in dogs since the time they branched off from their predecessors. There is debate about this idea.But Tomasello thinks that in the past fifteen thousand years, as human beings and dogs have evolved together, the basis for dogs’ ability to understand what you mean may have become something in their genes.
5.What made the dogs find the right container in the tests?
6.Who is the fastest when finding food?
7.What does Tomasello find out about dogs?
