Project description
This project studies Nectandra (Lauraceae), a tree genus with important cultural and ecological roles in Peru. Archaeological records show that Nectandra seeds were used in rituals by ancient cultures such as the Ichma and Moche, often as ceremonial offerings. Today, these seeds are still sold in Peruvian markets, suggesting a long history of use. The study combines genomic data from ancient seeds found at Pachacamac and Mateo Salado with modern samples from northern Peru. By comparing them, the project aims to identify which Nectandra species were used in the past, trace their geographic origins, and explore whether the same species are still used today. This research will help clarify the taxonomy of Nectandra and provide insights into ancient trade routes, plant use, and the connections between
people and forests over time.
