“…It has long been proposed that manioc or other root crops could have provided a significant source of carbohydrates (e.g., Bronson, 1966;Coe, 1961;Lowe, 1967: 59, 128;Lowe, 1975: 10-14; see also Clark et al, , 2010. This is a likely possibility, especially given the importance of manioc as a staple crop during the Classic period (Sheets et al, 2011(Sheets et al, , 2012 and its documentation at some Formative (Hather and Hammond, 1994) and Archaic period (Pohl et al, 1996;Rosenswig et al, 2014) sites in the Maya area. Further, Cyphers et al (2013; see also Cyphers and Zurita-Noguera, 2012) propose that manioc was the primary source of cultivated carbohydrates for the inhabitants of San Lorenzo during the polity's late Early Formative period florescence.…”
