As we know, we human has our own ways to communicate with each other, and the most important one is language. Human has lot of languages. People from different countries and different races might speak different languages. And those languages only known by themselves. So what about animals? From my point of view, different kind of animals also have different kind of ways to communicate with each other, but do they have languages? As we know, birds sing to each other to communicate with each other, some mammals like bears and lions also can communicate with each other by voice. So I do think animals have their own language. Although their brain were not smart than human beings, they can still create their own language.
