What is the evolutionary advantage of walking on two feet?
I was just wondering, since it required a lot of 're-jigging' inside of us.
Learning how to Balance standing upright;
Change the physiology of our eyes;
Changing how the whole Chest cavity is hung;
Why would we do that?
There are two clear advantages to humans walking on two feet as opposed to four:
1. It allows us to see over more obstacles thus helping us see prey, predators, mates, environmental dangers, etc. more readily.
2. Walking upright exposes more of the body to the elements which helps to regulate body temperature.
There are no doubt more reasons than that but these two are the main ones.
Remember: All of these changes took place gradually so our bodies adjusted well to them.
