Gravity Bipedalism and Human Evolution
It is suggested that a pivotal part of our evolution is the expansion of the dopaminergic system. Dopamine levels are highly heritable and extremely beneficial to brain function and health. The thing is you only get a boost of dopamine as a reward for perceived success or the act of smiling. The action of contracting the orbicularis oculi to squint the eyes and contracting the zygomatic major to stretch the mouth, increases dopamine levels. So it would be great if you could hold a smile all day and pass on those highly heritable benefits to your progeny. The thing is you cant hold a smile all day, its tiring. So mother nature came up with a work around. The muscles we use for looking happy are actually antigravity muscles. This means that all we have to do to activate an imperceptible smile on our faces is be upright.
What this means is that when we evolved bipedalism, these antigravity muscles would have been subjected to much stronger impact forces. These walking forces cause antigravity muscles to contract much more vigorously and therefore increase the amount of dopamine released. Well this is a very simple way of using gravity as a power source. In Homosapien these muscle groups have even grown to be the largest of any primate; even a 600lb gorilla. They have also gradually remodelled the bones they are attached to (fossil record), creating localised areas of robusticity.
In short, bipedalism shakes the face, causing a muscular reaction that increases dopamine levels. Each successive standing generation increases its dopamine levels by merely standing.

Hi Smil..y,
Reading your post, I didn't smile for real, but I felt as if I did. Has it increased my dopamine level?

I was just kidding, but what I meant is that we are able to feel good without smiling, which means that we are also able to feel nothing while smiling. We can lie on a feeling the same way we can lie on an idea. Now here is a serious question: before we begin feeling good, is it dopamine that triggers the good feeling or is it the good feeling that triggers the dopamine?
