Ancient cultures from Africa to Asia to the Mediterranean share core myths such as the animal pursued by a hunter who is transformed into a constellation, or a sculptor falling in love with a statute that comes to life, or a clever hunter outwitting a monster who keeps animals in a cave. This Scientific American article describes a method to trace the origin of stories through waves of human migration carrying the stories around the globe.

Although the animals and the constellations may differ, the basic structure of the story does not. These sagas all belong to a family of myths known as the Cosmic Hunt that spread far and wide in Africa, Europe, Asia and the Americas among people who lived more than 15,000 years ago. Every version of the Cosmic Hunt shares a core story line—a man or an animal pursues or kills one or more animals, and the creatures are changed into constellations. | Folklorists, anthropologists, ethnologists and linguists have long puzzled over why complex mythical stories that surface in cultures widely separated in space and time are strikingly similar. In recent years a promising scientific approach to comparative mythology has emerged in which researchers apply conceptual tools that biologists use to decipher the evolution of living species. —Scientific American
