Charles Darwin's 'The Origin of Species' is probably the best-known, least-read book. One of the most important achievements of the past millennium, it did for biology what Galileo did for astronomy - made it into a single science rather than a collection of unrelated facts. Important though Origin remains, its examples and intricate Victorian prose are now a century and a half old. They are ripe for renewal and reaffirmation. Writing as 'Darwin's ghost', eminent geneticist Steve Jones updates this seminal work - and restates evolution's case for the 21st century.
