Oh come on, back peddling are we. Your previous posts made much of the assertion that animals eating grain allowed more meat intake and the rise of complex cultures, when in fact grain was not an animal food and in fact no difference in meat intake can be deduced as being different then when hunting and gathering was the mode of production. In fact, it is the common view that less meat was eaten, the animals were valued for traction, milk, hair and wool, hides, and other products as much as anything. Meat is an expensive product in terms of energy input compared to energy out and the great population increases were based on the greater energy from grains.
