By the bones, japanese faces a few thousand years ago were much wider and heavier boned than now. The article said the theory was that people have been steadily eating softer and softer food, which does not exercise the muscles and bones enough in childhood, which results in less robust faces. Not a genetic thing, an environmental effect of different food. So Japanese faces are getting more triangular, with very narrow and weak jaws, and uneven teeth. My wife, for example, had 6 teeth pulled to make room.
