The Zoologist's Guide to the Galaxy

The book argues that the evolutionary processes that are observed operating on Earth are universal, and a necessary requirement for the presence of complex life on any planet. As a result, many aspects of animal behavior are likely to be present in the equivalent lifeforms on alien planets. This includes certain features of social behavior, communication, and movement, the evolutionary origin of which on Earth is underpinned by universal processes.
The book has been praised by critics for its accessibility and engaging conversational tone, and described by Richard Dawkins as "A wonderfully insightful sidelong look at Earthly biology". Provided by Wikipedia
