yes, great set of charts/ graphics.

I did not realize the limitations on indigenous Western hemisphere populations was due to lack of domesticated plants and animals. But to check, lamas were native, right? Just perhaps not suitable as plow animals? Plus mountainous region not good for plowing/good soil either?

Is it also fair to say that the work effort for maize/corn was higher than wheat or other grasses for a given net nutritional value output?
