This chapter assesses how migration patterns can be detected in bioarchaeological and paleoanthropological contexts. Using quantitative genetic models and simulation methods, it demonstrates that past migration has a small or undetectable biological effect when population or migrant numbers are small, migration is a single event, and/or genetic drift has a long time to operate. The examples stress the need for clearly defined testable models of how population characteristics behave under various migration scenarios. The chapter argues that model-bound analyses of prehistoric population structure best evaluate competing ideas about past migration because they explain biological variation in terms of clear, mathematically defined processes without traditional hypothesis-testing frameworks and ad hoc explanations.
