language is one of the most important things that a human learns. Without the creation of language we would have no idea what our past was or how to communicate with others,We'd be living a completely different life.  A couple million years ago all we had was grunts and calls but with the Great Leap it evolved to being sentences and words differing us from other animals because of the sophistication. But animals learned how to communicate with their behavior to each other. Like other animals we do learn to recognize and define sounds that could come from predators or anything dangerous. In the book The Third Chimpanzee by Jared Diamond,  he talks about monkeys and how they communicate, specifically the Vervet monkey because they also have to learn how to actually pronounce things, like different calls to other monkeys. Many animals also communicate like this but theirs are especially interesting because of the pronunciation. I find the idea of animal communication other than just behavior sort of confusing because we cannot know exactly what they mean as said in The Third Chimpanzee “ are vervet sounds words or sentences? Does the leopard call mean “Leopard!” or does it mean “there goes a leopard” or “watch out for that leopard!”. Maybe it means all of that and we’ll never know.” (Diamond, page 134).
