I have some revealing facts about human evolution and why gravity and air mass creates differences in our bodily structure.

The higher in elevation you are, the less effect gravity holds on an air mass, therefor the higher you are the less oxygen you can utilize. Thus this explains why people of Himilayan Andean origin are short, because height and evolution.

Thus we can conclude that people of origin closer to the sea, are taller, because oxygen is more rich, thus a higher quantity of molecules, thus a larger human.

If we go back even further, and consider rising sea levels, we can further conclude that if humans existed in a 'pre-flood' state, they'd have been massive compared to humans today. They very well could have been eight feet tall, if the ocean was a mile less deep.

This thought occurred to me when looking at how storms form and where they form. The largest storms in the world form over the ocean, but not only because of the expanse and lack of elevation change. There are 'hotspots' of meterological activity over the deepest depths of the oceans, the trenches. Gravity has less pull on the air mass above, so when a storm brews over these regions, you get particularly high cloud top formations and nasty 'hurricanes' an 'typhoons'. The storms linger and follow these trenches just based on the pull of gravity.

In a nutshell, elevation is the single greatest factor that contributed to human evolution.
