“…As discussed above, the morphology of maize is the product of genetic, environmental, and other developmental factors (Adams et al, 1999;Benz, 1994b;Goodman and Paterniani, 1969;King, 1994;Sánchez González et al, 1993;Turkon, 2006). Indeed, researchers have studied maize at the morphological level to ascertain the possible races of maize present in archaeobotanical assemblages as well as the production of maize in distinctive ecological contexts (Benz, 1994b;Benz and Iltis, 1990;Bird, 1994;Bird and Bird, 1980;Doebley and Bohrer, 1983;Johannessen et al, 1990;King, 1994;Miksicek et al, 1981;Huckell, 2006;Turkon, 2006;Villa Kamel et al, 2003).…”
