          The Journey of Man

          2002 book by Spencer Wells

          The Journey of Man: A Genetic Odyssey is a 2002 book by Spencer Wells, an American geneticist and anthropologist, in which he uses techniques and theories of genetics and evolutionary biology to trace the geographical dispersal of early human migrations out of Africa.

          The book was made into a TV documentary in 2003.[1]

          Synopsis

          According to the recent single-origin hypothesis, human ancestors originated in Africa, and eventually made their way out to the rest of the world.

          Spencer Wells is a scientist, author, documentary filmmaker, population geneticist and director of the Genographic Project from National.

        1. Geneticist Spencer Wells describes how he uses DNA samples to trace our individual origins going back generations.
        2. Around 60, years ago, a man--identical to us in all important respects--lived in Africa.
        3. Spencer Wells takes us on a globe-trotting journey through human history, showing how we can learn from our ancestors in order to survive and.
        4. Spencer Wells is a National Geographic Explorer-in-Residence and the Director of the Genographic Project, an exciting five-year scientific.
        5. Analysis of the Y chromosome is one of the methods used in tracing the history of early humans. Thirteen genetic markers on the Y-chromosome differentiate populations of human beings.

          It is believed, on the basis of genetic evidence, that all human beings in existence now descend from one single man who lived in Africa about 60,000 years ago.[2] The earliest groups of humans are believed to find their present-day descendants among the
