Are Long Legs Really Better?

According to Herman Pontzer, Ph.D (Journal of Experimental Biology), fossil records show that 2 million yrs. ago, human leg length suddenly began to increase...presumably to conserve energy during long distance travel. Pontzer's model predicts the rate of energy use related to limb length, i.e., longer legs = less force production = lower energy cost.

To test his equation, Pontzer put people, dogs and goats on a… Continue
