Plant domestication is merely a process of human selection of consecutively larger or more desirable seeds or fruit.
I read a study that showed a complete domestication of a Mideast wild wheat field in 200 years (i.e. converting to human-selected grain that yielded larger seeds and kept them in the pod for predictable harvest). I think the study was predicated upon sedentary population, which would be possible in the tropical savannas of Bolivia.
So my question is why wouldn’t these plants have been domesticated and farmed? I suspect so much more of that was going on around the world. I’d even consider North American Indians management of oak forests as a form of farming.
