Long ago people started dreaming of extraordinary abilities. To fly, to possess very keen sense of smell… Numbering these dreams of humanity will take a significant time. Some abilities are typical for animals. Recall legends about werewolves. Or sphinx. At those times it was just a fairy tale, a product of imagination. But nowadays science is much more developed.
What if humans can be crossed with some species of animals?? With birds for example?? To be able to fly. With wolves to gain extrasensory abilities. With fishes to be able to live underwater. For me this sounds very much attractive.
