Cultivated seeds have been part of the human experience for thousands of years and are crucial to ensure food sovereignty. Even though they are ordinary goods and widely disseminated throughout all agricultural territories in the world, it is a difficult task to find historical evidence of the seeds cultivated in each region. Several factors can help to explain this absence, such as seed biology and the environment, which can have negative effects on seed preservation, or culture, as scarce details written about what was cultivated. However, data on seeds cultivated in specific places and times has proved to be fundamental for understanding different dimensions of human communities, helping to have more robust interpretations of the past, namely in social, cultural and technical aspects related with agriculture, trade, storage, food production, cooking and consumption. In recent decades, different sciences have contributed to the development of knowledge and useful tools to identify seeds of species&varieties cultivated in the past. Exploring transdisciplinary and interdisciplinary approaches, contributions from genetics, chemistry, archaeology and botany have made it possible to bring new data to the discussion, stimulating the reassessment of information already known from different historical sources, such as written documents, herbarium plants, artefacts or iconography. This session aims to bring together papers that allow either to identify the methodologies that are being built using contributions from various sciences, or to assess the relevance of the data to explain the geographic, social, morphological and environmental trajectories of the various cultivated species. Thus, communication proposals from all areas are welcome (archaeobotany, genetics, archaeology, botany, anthropology, history, chemistry, biology, agronomy, cooking, geography…), helping to identify the seeds that have fed us for thousands of years.
