In this lesson, the fourth in a set of lessons exploring migration, genetic markers, markers in context, and the Genographic Project (a five-year study of human origins and migration based on genetic markers), students will learn what the Genographic Project will leave for future generations, both in cultural preservation and knowledge of our common ancestry and make educated projections about our common future. They will examine why the timing of the project is critical. Students will consider ways in which the project is impacted by scientific and technological advancements, which make such a study feasible for the first time in human history. They will consider the impact of increasing globalization, which makes collecting and interpreting the project data more challenging. Students will assume the role of a researcher in the project tasked with documenting the contributions indigenous groups have made to the story of the human journey. They will understand why indigenous communities play such a crucial role in unlocking the secrets of our common ancestry, examine how those communities are being threatened, make projections about future challenges to their ways of life, and consider how research such as the Genograhic Project can play a role in preserving them.
