The next critical step is establishing a local isotopic baseline. This requires collecting modern and archaeological samples from the site and its surrounding region: plants, animals, soil, and especially small mammals like rodents that have limited home ranges. Ideally, baseline data should account for geological heterogeneity and potential changes in the environment over millennia (e.g., shifts in rainfall patterns). With a reliable baseline, each human sample is plotted and classified as local or non-local. Clusters of non-local individuals suggest population movement, trade networks, or exogamy practices. Statistical models help quantify the probability of origin, though pinpointing an exact source area remains challenging unless the isoscape is highly detailed.
