Better the Arm, Bigger the Brain

Updated: Jun 21, 2020

We weren’t always equipped with a canon arm.


About 2 million years ago, our ancestors developed a few key structural changes that changed us from climbers and scavengers into living catapults:⠀

  1. Our waists got a little wider ⠀

  2. Our shoulders a little lower⠀

  3. Our wrists became more flexible⠀

  4. Our upper arms rotated a bit more⠀

Once we got the hang of our “weeble wobble” power and learned to put a point on a stick, we became not only the deadliest creature on the planet, but the smartest. ⠀

The better we threw, the more intelligent we became.


Our ability to produce powerful throws was crucial to increasing the amount of hunting we performed. Success at hunting allowed our ancestors to become part-time carnivores, eating more calorie-rich meat and fat and dramatically improving the quality of their diet.


This dietary change led to large shifts in our ancestors' biology, allowing them to grow larger bodies, larger brains, and to have more children.


Bigger brains likely led to an increase in humans ability to project into the future, visualize possibilities, think in the abstract, and communicate within larger groups.


Thus, it is a likely scenario, that language, literature, medicine and even love are a direct result of our ability to spear a deer at 20 yards (or in present terms, throw a baseball 95 mph).


Throwing and hitting a target is about finding order in chaos. The more you're able to think in sequence, the more ideas you're able to string together.


Interesting food for thought.....
