Riddle of the Cambrian Explosion

Riddle of the Cambrian Explosion (カンブリア爆発の謎)

This book is about Riddle of the Cambrian Explosion which means an explosion of number of species on the earth about 530 million years ago.

Recently, I'm reading various books on evolutionary theory, and at first I expected detailed discussion about the reason why it happened. But, this book describes various creatures of those days and author's work on bionomics of anomalocaris based on numerical simulation.

Basically, I enjoyed the history of strange ancient creatures, but I'm looking for books concentrating on more detailed theories of evolution. :)
