Canine Teeth and Lethal Weapons:
Was the Fabrication of Wooden Spears and Digging Sticks by Human Ancestors Responsible for the Evolution of Bipedal Locomotion?
When a population of prehistoric apes began to use long, sharpened sticks as lethal weapons, the ability to attack predators and prey from a safe distance gave an advantage to those individuals who could best stand, walk, and run on two legs, leading to a complete redesign of the primate body and the evolution of full upright posture. This work in progress is intended as a scholarly article addressed to a professional audience.
