I will recommend the book "The Story of the Human Body" by Daniel E. Lieberman. In his section "Unwise Wisdom Teeth", he writes: "Just as your limbs and spine will not grow strong enough if you don't sufficiently stress your bones by walking, running, and doing other activities, your jaws won't grow large enough for your teeth and your teeth won't fit properly if you don't stress your face sufficiently from chewing food." A fascinating book. One observation: modern human hunter-gatherer mothers typically wean their children at age three, while a mother who is a subsistence farmer can wean her children between one and two years. Thus, humanity underwent a population explosion once we started farming instead of hunting and gathering.
