Man’s Upright Posture

     Somewhere I read that our upright posture resulted from coming down out of the trees and needing to run fast in order not to get eaten by predators.

     I thought about this, it made no sense because even relatively slow big cats can run much faster than we can.

     But then, it really wasn’t necessary to run faster than a predator, just faster than whoever is with you at the time.
