First Amazon-Andean Crop Plant Transfer And Corn Processing In Peru 3600-4000 Years Ago
Heading to the supermarket to pick up some corn flour, a couple of tomatoes or a can of beans usually doesn't conjure up the notion of 10,000 years of agricultural development in the Americas--a transition from hunter-gatherer cultures to agricultural cultures actively developing and trading new food crops. But this transition is still inadequately understood. New excavations and a growing collection of plant microfossil remains rapidly adds pieces to this puzzle.
A multidisciplinary team excavated a stone house at Waynuna, north of Arequipa on the western slope of the Andes and analyzed plant remains from three grinding stones.
