Reminds me of some of the discussion in Charles Mann's "1491", regarding the agricultural techniques of the Indians (honoring his use of that over Native Americans) before the Colombian Exchange [0]. The natives in South America had figured out symbiotic relationships between several plant species and grew them together in "Milpas" [1] (and how this goes against the "pristine land" myth many mistakenly hold regarding the Indian's use of the land).
"Pristine lands" lied far north of there, and were used as pastures and hunting grounds.
Agriculture was practiced in more southern lands, where the yields are higher. Corn comes from the south of North America, and potatoes, from north of South America. I think nobody had a delusion, even back in 1500s, that these were wild plants.
