Radiocarbon dating is essential to the study of early agriculture because it provides a reliable chronometric framework for dating archaeological sites and remains. By measuring the decay of the carbon-14 isotope in organic matter, researchers can estimate when an organism died, allowing them to establish a timeline for the transition from foraging to farming.12

Historically, archaeologists were often forced to date plant remains indirectly by analyzing the sediments in which they were found, as plants are typically smaller and more fragile than animal bones. However, advancements in radiocarbon techniques now allow for the direct dating of minute quantities of material, such as a single seed. This shift has made the direct dating of plant remains the standard practice in modern research, enabling more precise identification of when specific crops were domesticated. By providing accurate dates for these biological remains, radiocarbon analysis helps scientists map the independent development of agriculture across different regions of the world.1
