The human capacity for language divides our species from the rest of the animal kingdom. Language has not only allowed us to conquer all corners of the globe, but to devise writing, mathematics and all things thereafter.
But researchers can find many of language's basic design features in the communication systems of other animals. For example, many animals have particular calls for specific objects and meanings, and some even seem to combine calls in meaningful, albeit rudimentary ways. These lines of continuity, however thin, drive home the point that, at its essence, language is part of our biology.
