River Out of Eden: A Darwinian View of Life is a 1995 popular science book by Richard Dawkins. The book is about Darwinian evolution and includes summaries of the topics covered in his earlier books, The Selfish Gene, The Extended Phenotype and The Blind Watchmaker. It is part of the Science Masters series and is Dawkins's shortest book. It also includes illustrations by Lalla Ward, Dawkins's wife. The book's name is derived from passage 2:10 of Genesis relating to the Garden of Eden. The King James Version reads "And a river went out of Eden to water the garden; and from thence it was parted, and became into four heads."
River Out of Eden comprises five chapters. The first chapter lays down the framework on which the rest of the book is built, that life is a river of genes flowing through geological time where organisms are mere temporary bodies. The second chapter shows how human ancestry can be traced via many gene pathways to different most recent common ancestors, with special emphasis on the African Eve. The third chapter describes how gradual enhancement via natural selection is the only mechanism which can create the complexity we observe all around us in nature.
