In his new book, Richard Dawkins likens evolution to a river of genes that meet, compete with one another, unite, and sometimes split apart to form new animal species.

The distinguished scientist, writing with characteristic fluency, seeks to unravel the mystery of the origin of life. He argues that humans and all living beings are merely vehicles carrying genes, and that their primary function is the propagation of DNA.

He analyzes the theory of African Eve, describing and clarifying complex, remarkable phenomena of the living world while attempting to answer pivotal questions such as: Why do we inherit genes that cause fatal diseases? What is the purpose of life? What is the direction of evolution?
