> It's not possible to eat a Paleo diet today, as the plants and animals that existed in paleolithic times no longer exist today. Natural and artificial selection has changed our food supply so drastically that the foods available today are almost completely unrecognizable compared to their Paleolithic ancestors.

A modern day Paleo diet is merely about eating as closely to natural foods as possible, eating those foods optimal for our individual health, and cutting out all processed junk foods.

Simple. It is certainly based in reality, much more so than the dogma of Veganism.
