Everyone is familiar with genetically modified food, but did everyone here also know that animals, even humans can be genetically altered to look different or be developed by unconventional means.
For instance, in theory genetic engineering can recreate dinosaurs either through cloning or merging species together to form a similar result. Theoretically it is even possible to recreate a centaur (you know the half man, half horse fella) if done correctly. Such species are called chimeras or hybrids. Obviously, mankind is only in the early stages of this technology, but do not be surprised if one day a theme park like Jurassic Park actually becomes a reality. Many of the creatures you hear about in Greek myths, like the three headed dog, centaurs, pans, and Minotaurs are not that far from reality as once believed.
