Journey of man
How did the human race populate the world?
A group of geneticists have worked on the question for a decade, arriving at a startling conclusion: the “global family tree” can be traced to one African man who lived 60,000 years ago. Dr. Spencer Wells hosts this innovative series, featuring commentary by expert scientists, historians, archaeologists, and anthropologists.
By analyzing DNA from people in all regions of the world, geneticist Spencer Wells has concluded that all humans alive today are descended from a single man who lived in Africa around 60,000 years ago.
Modern humans, he contends, didn’t start their spread across the globe until after that time. Most archaeologists would say the exodus began 100,000 years ago—a 40,000-year discrepancy.
