It has been a long standing belief in a good number of people that animals are nothing more then unfeeling machines that have no intelligence. When faced with clear and concise evidence that this is not the case and that some animals are nearly as intelligent as the human animal yet they still deny it. What is that makes people so scared to admit that animals are more then they appear to be? Why is it such a hard thing to accept?
National Geographic has an excellent article on this very subject that provides examples of animal intelligence:

Anyone who owns a pet should find it hard to deny that animals don't feel emotions. Elephants mourn their dead. Dogs get depressed when their owners leave for vacation. I volunteer at an animal shelter by helping to make the cats more sociable. I have witnessed a ray of emotion in these cats from anger to joy. And yet....why is it also hard for people to admit that animals have as broad a spectrum of emotions as us?
