Starch and phytolith analyses of an assemblage of chert microliths from the Three Dog site, an early Lucayan settlement on San Salvador, Bahamas, yielded Zea mays, Capsicum, and possible manioc indicating that these domesticates were present by at least A.D. 800 or earlier in Cuba or Hispaniola and brought to the central Bahamas during its early peopling. The presence of corn at this site contradicts previously held ideas that it did not appear in the Bahamas until the A.D. 1200s. Starch granules tentatively identified as root/tuber starch were also found on the microliths, although we were unable to discern if these represent wild species and/or culturally transported wild or domesticated species. The presence of more than one species on the microliths, initially believed to have been manioc grater chips similar to those documented ethnographically, demonstrates multifunctional use. A broad-based plant diet that included maize and root/tuber crops was in place at least by the Archaic age in parts of the Greater Antilles and brought to the Bahamas, along with chilis, during its colonization by Ceramic age peoples.
