You don't think a vegetarian organization just might have slanted the facts towards their biased agenda?
How many of those veggies 'n fruits do you think were around in those cold Winters back then for man to readily pluck? Remember, the majority of human existance was pre-agriculture that modern folks often take for granted.
Sure, we took in a few nuts, seeds, the occassional fruit, etc. but we were a far cry from being the vegetarian caveman your vegetarian organizations would have you believe. Check with more objective sources next time you supply your references, or you'll naturally be challenged. So get over it and the vegetarian's fact-distorting PR machine and enjoy your low carb way of life! Why it's "important" to understand whether / if we were primarily veggie-eating vs. meat-eating is because despite your statement that you've evolved, we're relatively still the same "carbon-based units" that more-than-less digest and process sugars, regulate insulin, etc. as we've done for a long, long time - vastly outstripping the relatively recent agricultural age of a "blink of an eye" ten-thou years.
