True facts. Currently, man can't adapt to eating raw plants, because we don't have the digestive system of a ruminant.
Meanwhile, I feel that our ancestors though; precisely, the early men may have practised this until evolution occurred, because there was no such thing as cooking, then.
If we study humans biologically, and compare it to our intellect, It may show that man currently isn't completely a higher animal. Our biology is weak, whereas our intellect is high, the equation is balanced. This is vice versa for many animals.
We must cook to eat, and other limitations such as using vehicles to travel long distances, etc.
Man can't currently survive many things other animals face.

If we compare ourselves to some animals, I totally agree with you. The first thing in the affairs of man is survival. Man will eat anything as a last option to survive. Many might not survive it while might. Those few will reproduce to give offsprings that would be better adapted to eat what their parents ate/are eating. It is called natural selection.
Yes, that's true, I suppose, that's what we have been experiencing in the newer generation.
If you are starving to death it would seem stupid to eat grass since you would waste energy in its digestion. THe smarter thing to do is to search for the earth worms and other insects guarteed to be right beneath the soil. Where there is grass there is worms.
