Probably. It always amuses me that people automatically associate "paleo" with "eating mammoths every day", when a simple glance to other primates shows a heavily plant-based diet, on top of which, how many mammoths do they think our ancient ancestors were killing? Even well into the 20th century, meat was not an everyday food, and it's completely unnecessary (some argue harmful) to the human diet.
Books like "How Not to Die" opened my eyes.
