Ignore all the widespread information and prevalent opinions about this book and ignore the talks and speeches by Richard Dawkins dealing with Christianity and religion as such and don't let those form your opinion about this book without reading it and instead go and read it. It is incredibly well written and it deals with complex questions about life that ought to be interesting for basically anyone. I've found it to be a perfect introduction into evolutionary theories and even though it is 40 years old and many new facts emerged, the core is still sound and relevant. Maybe consider reading some current critique that points out how our new knowledge affected the theories presented in this book. ( )
