When we adopt an animal, people pat us on the back and congratulate us for saving a life. How noble! How selfless! How silly. Anyone who has adopted an animal knows that choosing the animal is seldom a part of the process.
The question isn't, "Do other species communicate?" Instead, the question is, "Why can't we understand each other?" A paper published this week may show that we're not the only animal wishing we could talk with a species other than our own.
Can any human speak even one word of another animal's language? No, but perhaps it's better that way, because if we could speak to them, how would we explain our systematic use and abuse of all the other species?
