This finding strengthens the association of this event with the development of sedentary societies and perhaps even has implications for the inception of human social inequality. Domestication is a peculiarly human endeavor. The idea that we can learn about ourselves by studying man-made animals is well worn and considerable effort has been put to the cause 1 2 . Although dogs are surely the first domesticate 3 the history regarding the location of their transformation from wolves and the peoples responsible for it has been confusing with genetic evidence pointing to Europe the Far East and places in between 4-6 . Although other waves of domestication - of chickens some pigs llamas and water buffalo among others - took place in China and the Americas 7 most of the Western barnyard animals and the cat were domesticated between 12 000 and 8 000 years ago in a region of the Middle East known as the Fertile Crescent 7-10 and are exclusively the product of a sedentary agricultural civilized life 7 9 11 . Dogs have been considered as an important exception the suspicion being that they were domesticated earlier and perhaps elsewhere the product of a still more distant and primitive hunter-gatherer past 12 Figure 1 . The conventional thinking has been that wolves being highly mobile were naturally well equipped to follow bands of hunters of no fixed address as they roved the end of the Paleolithic in search of game. Protodogs might have scavenged kills left behind by humans as they moved in search of new game .
