        Secrets of the Sky Tombs | Adapting to Survive at High Altitude

        Examine DNA evidence that links the Himalayan population to ancestors from faraway lands and explains how today’s inhabitants survive at altitude, in this media gallery from NOVA: Secrets of the Sky Tombs. By studying small variations in DNA sequences and comparing them across populations, geneticists determined that early Himalayan settlers came from East Asia. Sequencing also revealed that the Himalayan people survive at high altitude thanks to a second DNA variant inherited from a now-extinct human species. This resource is part of the NOVA Collection.

        Tracing the Ancestral Origins of the Himalayan People

        Geneticists learn the ancestral origins of the Himalayan people by examining their DNA and comparing the sequences with those of other groups in India and Asia.

        A Himalayan Adaptation Supports Evolution in Action

        The discovery of a second DNA variant that helps Himalayan people live at high altitude links modern human species with an extinct human ancestor and provides evidence of continuing human evolution.
