An obligate carnivore specialized in hunting large megafauna is disadvantaged when that prey is hunted into scarcity. A similar species with more metabolic flexability was advantaged, relatively, by that change. That doesn't say much either way about the nutritional pros or cons of carnivory for a modern Homo sapien. My own experience with it is positive, and I'm glad I can buy hunks of megafauna from the cooler at my grocery, unlike those poor neanderthals. My nutritional flexability has decreased as I've aged. My IBS means I can't handle the fiber I used to, and have been forced into a low residue diet. I eat like a neanderthal now because my compromised digestion handles it better. That makes me wonder if our consumption of vegetation has always been a compromise ... one that helped us outsurvive neanderthals, but still sub optimal.
