The Journey of Man: A Genetic OdysseyAllen Lane, 2002 - 224 pages Around 60,000 years ago, a man walked the soil of Africa. Every person alive today is descended from him. How did he come to be father to all of us - a real life Adam? To find out, Spencer Wells embarked on a unique voyage of discovery, travelling the world and deciphering the genetic codes of people from the Sahara Desert to Siberia. He reveals how our DNA enables us to work out where our ancestors lived, (and who they may have fought, loved and learned from); to re-trace their footsteps from Africa to the far corners of the earth ; to understand how we evolved into such a huge variety of sizes, shapes and races - and, ultimately, to create a family tree for the whole of humanity. |
