How was bipedal locomotion important to hominin evolution?

Bipedalism freed the hands so they could be used to cart food,  make and use weapons and other advantages of freed hands.  Bipedalism is a much more efficient way to walk and run and this  fact is quantified.  Bipedalism raised the early proto-human above the horizontal so  he could see predators approaching.  Bipedalism is a much more efficient design to cool down  overheating bodies.
