The Animal Planet is giving a special on the animal which happens to be my Chinese Zodiac sign and the only animal in the Chonese Zodiac that is 'mythical'. My regular zodiac sign is also mythical. They claim that all these different cultures that have never had contact with eachother describe the same aimal as if it were real. Although there has been no fossil evidence, biologists were called in to explain how dragons would realistically breath fire, fly, and behave assuming they really existed. The biologists claim it would be completely possible for an animal to conduct such behaviors given the proper biological make up. Do/Did they exist?
