One thing is clear: our brains required tremendous amounts of energy. Cooking starches allows us to extract more energy from them. Meat eating is calorically dense too and so that could of played a role (see Expesive Tissue Hypothesis). I have read meat-eating was hugley beneficial during resource scarcity. The critical question is what diet do we thrive on? A carb rich plant-based diet is my guess based mostly on Dr. Michael Greger's work on summarizing nutrition science literature [0]. But I shall be convinced otherwise if the science is there. [0] http://nutritionfacts.org/ http://nutritionfacts.org/
