Extract from The Ancestor’s Tale

The Guardian has this extract from Richard Dawkin’s latest book, The Ancestor’s Tale: A Pilgrimage to the Dawn of Evolution.

“The Ancestor’s Tale is cast in the form of an epic pilgrimage from the present to the past. All roads lead to the origin of life. But because we are human, the path we shall follow will be a human pilgrimage to discover human ancestors. As we go, we shall greet other pilgrims who join us at a series of rendezvous points, as we encounter the common ancestor we share with each of them.”
