Fragments of ancient Theobroma cacao DNA have been found in pottery sherd residues from the Etowah site in northwest Georgia, tracing back to the 11th and 12th centuries CE. Adam King and colleagues recognized this as the initial evidence of cacao consumption in the Mississippian realm, marking an extraordinary discovery in this area. The existence of cacao, a plant that thrives in tropical climates, in the southeastern United States implies interactions with regions of Central and South America where cacao is cultivated. The research disputes earlier conclusions, demonstrating that chemistry alone cannot differentiate between cacao and yaupon holly residues.<\/p>\n
The research included DNA analysis of the sherds, with sequences filtered to validate the presence of cacao. Thirty-six sequences from two sherds surpassed thresholds for cacao identification, reinforcing that ancient cacao DNA was present on the pottery from historically rich feasting contexts. Although this does not directly prove cacao consumption, it indicates its existence at Etowah during an important cultural era.<\/p>\n
The genetic analysis points to connections with contemporary cacao groups found in Maya and Ecuadorian settings. While still in the preliminary stages, these findings suggest long-distance relationships without definitive geographical origins. This revelation places Etowah in wider discussions regarding cacao distribution, while archaeogenomic studies may further illuminate these ancient connections.<\/p>\n","protected":false},"excerpt":{"rendered":"
