The video explores how lice are used to study human migration patterns. Scientists, like David Reid, analyze lice DNA to trace the movement of human populations from Africa to the New World. The research reveals unexpected insights into human history, such as the migration routes from Asia. Ancient lice from Peruvian mummies provide further evolutionary clues. Despite their research value, lice pose challenges due to their resistance to treatments.
