I'm not really sure that this fits under Biology, but oh well... I was wondering how animals, such as dogs, learn to speak their own language. One would think there would be two possible explanations of how they do this: one being that they are born with an innate understanding of the language, or the other being that the parents of the animal (dog in this case) teach them how to speak. Either choice would carry profound implications about the intelligence levels of animals. If the second possibility is true, then the language of animals is much more complex then previously thought! A language as complex as this would be could only be used by beings of significant intelligence.
