Human/Non-Human Animals

What makes an animal "human" or "Non-human"? In my opinion, this is not an accurate measure, as there is only one species that is truly human: humans. However, those that are like humans and able to learn, reason, and grow is what needs to be placed. I believe that individuality and intelligence play the biggest part in what makes an animal 'human'. If the species preserves it's own life, yet can still show consideration for others of its own kind, then that is a good basis on what is 'human'. For instance, worms do not seem to have much care about any other creature, even other worms. However, dogs are able to learn tricks, figure out their own sense of what is right and wrong, and have a family. This is an important part to discover what makes an animal 'human'.
