Re: Sorry for getting all unfunnybusiness...
Not that I'm disagreeing with the essence of your comment, but our diets involved a lot more cooked vegetables and grains than you might think and our digestive systems reflect that. I've heard scientists theorize that the big thing that caused the evolution of homo sapiens as super smart and awesomesauce was cooking food, since it made it easier to digest, so our bodies could redirect the energy no longer used for digestion into evolving massive brain power. Not saying you're wrong, just reminding everyone that digestion and diet is way more complex than we think it is.
