There is no hard evidence werewolves exist. However, werewolf stories go so far back as the Epic of Gilgamesh, one of the earliest works of human writing, and have persisted throughout history. Common, scientific explanations for stories of werewolves include ergot poisoning, mental disorders, Hypertrichosis (disorder which causes excessive hairiness), rabies, and wolf-dog hybrids (they're much more aggressive than wolves).
