（单词翻译）

 In terms of evolution, there has to be a reason for barking, or it probably wouldn’t be there. Is it to warn of predators1? But dogs bark when there are no predators around. Is it play? Some dogs play without barking. In fact, people who study canine2 behavior find there isn’t much of a pattern to barking–it seems to be an all-purpose noise. Now here’s another fascinating thing: adult wolves don’t bark. They growl3, and they whine4, but no barking. And dogs evolved from wolves. So where did the bark come in? Mark Feinstein and Ray Coppinger of Hampshire College in Massachusetts have a theory. These biologists have noted5 that while adult wolves don’t bark, adolescents do. Wolf pup barking seems to be an intermediate noise you grow out of.
