Dragon as Amalgamated Uber-Predator
Let’s begin by looking at the most widespread and celebrated of all mythic monsters—the dragon. This creature, in one guise or another, appears in almost every mythology and has been the subject of many books and countless articles. Perhaps the most intriguing of these examinations is An Instinct for Dragons by anthropologist David E. Jones. Jones argues that the image of the dragon is composed of the salient body parts of three predator species that hunted and killed our tree-dwelling African primate ancestors for about sixty million years. The three predators are the leopard, the python, and the eagle.
