Throwing Ourselves Two Million Years into Human Advancement

Divisions of Labor were born with the human ability to throw a projectile.   Research has taught us that as people learned the ability to throw sticks, stones, rocks, and weapons the social nature of life began to change. Where humans were limited in their food supply, the ability to throw objects created more efficient hunting that led to increased calorie intake. Researchers recently published the interesting findings on human development in the journal Nature. The shoulder has developed in such as way to maintain elastic energy so that when it is released it can produce the fastest motion possible. Other species cannot do this. Where chimpanzees can throw 20 mph the human can often achieve up to 100 mph. This makes the projectiles much faster than the natural speed in the environment. This faster speed creates higher levels of food and nutrition obtainment which fosters population growth.  The division of labor occurred because food was a commodity that could be bartered
