人,基因码之旅Journey Of Man Dr. Spencer Wells is a charismatic and compelling 31-year-old scientist whose pioneering work is uncovering the definitive picture of humanity\'s past, a past that stretches so far back in time that no historian could hope to know it. Spencer runs his own laboratory at the Welcome Trust Centre for Human Genetics at Oxford University where he combines his expertise in the field of population genetics with his passion for historical storytelling. From thousands of samples taken from all over the world in the last decade, Spencer and his colleagues have decoded the history in our genes and can tell the definitive story of the human race--from the first people to leave Africa to over 6 billion people in every corner of the globe today. Astonishing revelations show beyond a doubt that everyone alive in the world today is descended from one man--the Adam of the human race--as little as 50,000 years ago. The epic tale of man\'s global conquest unfolds like a detective story. With new genetic evidence behind him, Spencer pieces together a complete history of modern humans from clues gathered along the way: facial features of people alive today, cultural and fossil remains, meteorological records. He will draw on the expertise of archaeologists and anthropologists to build a picture of how, why and when the great migrations occurred. From our earliest roots in Africa, to our amazing invasion of the world, through periods of near extinction and others of great expansion, Spencer will take us on a travelogue that involves every person alive today.
