Evidence for eating anything we could get our hands on, including quite a bit of meat, is abundant in paleoarchaeology. This is quite far from the truth. The hadza are specific about the foods they gather and are known to have a number of food taboos. Women and children are forbidden from eating hearts, for example, while men can't eat tortoises. Also, the carbs in the title are primarily coming from tubers, often called underground storage organs (USOs) in the literature. Grain is a much later thing, as you mentioned. The thing you're critiquing is ethnographic analogy. The sucks doesn't do a good job of clarifying this, but the accepted modern usage is not to say "this is exactly how ancient humans lived", but rather to illuminate a small part of the spectrum of possible lifeways and what constraints they might have been optimizing.
