I don't think either of us is an expert in paleolithic food consumption. All I know is what I've read on Dr. Eades' blog: paleolithic peoples were top-level predators and probably drove some big-game species to extinction. 40,000 years ago, what percentage of the earth's climate was suitable for growing coconuts? What percentage of people in climates inhospitable for growing coconuts got them by trade prior to the neolithic period? Just as you're sure that coconuts were available to most people back in the day, I'm sure they weren't. Until one of us serves up the evidence of ancient diets or climatic data, we're both entitled to our version of history.
