Why Walking on Two Legs Saves Energy
In an intriguing study at the University of California, Davis, researchers delved into the secrets of our ancestors’ transition to bipedalism by training chimpanzees to walk on treadmills. The results were eye-opening: bipedalism proved to be far more energy-efficient than moving on all fours, offering a whopping 75 percent energy savings compared to our chimp cousins’ quadrupedal gait.
As we explored earlier, this newfound efficiency may have endowed our ancestors with a combat advantage, as suggested by David Carrier. It’s a compelling glimpse into the evolutionary forces that shaped our unique human journey.
