"Human beards, then, are part of a suite of anatomical, modifications around our ancient social weapon. The evolution of chins, teeth, voice, and beards has changed to modify the signals being transmitted from the mouth. Analogous to the caribou mane, human beards originated as a fake exaggeration of the weapon wielder. Though we have virtually abandoned the jaw as a physical social weapon, it still is an important signal source - and so is that chin-mane we call a beard."
