“…Both crop complexes are well-established in the Ethiopian/Eritrean highlands by the early to mid-first millennium BC, when the region was occupied by sedentary farming communities (Boardman, 2000;Bard et al, 1997;D'Andrea, 2008;D'Andrea et al, 2008b;. There is a longer history of livestock husbandry in the Horn, with the earliest documented cattle dating to the third millennium BC (Clark and Prince, 1978;Clark and Williams, 1978;Brandt, 1984Brandt, , 1986Brandt and Carder, 1987;Clark, 1988). Given these circumstances, stable isotopic analyses have great potential to demonstrate not only the dietary significance of African vs. Near Eastern crop complexes in the highlands, but also to estimate the proportions of plant vs. meat sources in pre-/Proto-Aksumite diets.…”
