Ok, I started this thread due to the thread I have a hypothesis!. Now, it started to talk about evolution changing due to gravity changes due to the heating and cooling of the atmosphere. I started looking it up to help out with some answers and came across this great research paper. It is a wonderfularticle in plain English with only a touch of math. But provides a clear picture on how gravity affects the human body. It is only 29 pages and is very informative. Please read and give your thoughts.
