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.

"This collection of twenty-two research papers explores the creative interaction between evolutionary and molecular biology, philosophy, and theology. It is the result of the third of five international research conferences co-sponsored by the Vatican Observatory, Rome, and the Center for Theology and the Natural Sciences, Berkeley. The overarching goal of these conferences is to support the engagement of constructive theology with the natural sciences...

"We think of medical science and doctors as focused on treating conditions--whether it's a cough or an aching back. But the sicknesses and complaints that cause us to seek medical attention actually have deeper origins than the superficial germs and behaviors we regularly fault ... Jeremy Taylor [argues that] we can trace the roots of many medical conditions through our evolutionary history, revealing what has made us susceptible to certain illnesses...

Using the latest DNA reconstructions and cutting edge technology, scientists investigate the location of the first woman in the human race.

"Join geneticist Spencer Wells and a team from National Geographic's Genographic Project as they trace the human journey through time, from our origins in the heart of Africa to the ends of the world. Cutting edge science, coupled with a cast of New Yorkers -- each with their own unique genetic history -- helps paint a picture of these amazing journeys. The human family tree answers some of humanity's most burning questions -- who we are and where...
