Travel backward through time from today's scattered billions to the handful of early humans who lived in Africa 60,000 years ago and are ancestors to us all.
In Deep Ancestry, scientist and explorer Spencer Wells shows how tiny genetic changes add up over time to a fascinating story. Using scores of real-life examples, helpful analogies, and detailed diagrams and illustrations, he translates complicated concepts into accessible language and explains exactly how each and every individual's DNA contributes another piece to the jigsaw puzzle of human history.
The book takes readers inside the Genographic Project, the landmark study now assembling the world's largest collection of DNA samples and employing the latest in testing technology and computer analysis to examine hundreds of thousands of genetic profiles from all over the globe.
Spencer Wells is an Explorer-in-Residence at the National Geographic Society and the director of the Genographic Project. After studying under genetic pioneer Luigi Cavalli-Sforza at Stanford University, he began an unusual career that combines science, writing, and filmmaking.
His acclaimed first book, The Journey of Man, combined his own DNA research with the work of archaeologists, paleoanthropologists, paleoclimatologists, and linguists to show how modern humans came to populate the planet.
