The Zoologist's Guide to the Galaxy

What Animals on Earth Reveal about Aliens – and Ourselves


A Times/Sunday Times Book of the Year


'A wonderfully insightful sidelong look at Earthly biology'
Richard Dawkins

'Crawls with curious facts' Sunday Times

We are unprepared for the greatest discovery of modern science. Scientists are confident that there is alien life across the universe yet we have not moved beyond our perception of 'aliens' as Hollywood stereotypes. The time has come to abandon our fixation on alien monsters and place our expectations on solid scientific footing.

Using his own expert understanding of life on Earth and Darwin's theory of evolution - which applies throughout the universe - Cambridge zoologist Dr Arik Kershenbaum explains what alien life must be like. This is the story of how life really works, on Earth and in space.

'An entertaining, eye-opening and, above all, a hopeful view of what - or who - might be out there in the cosmos' Philip Ball, author of Nature's Patterns

'A fascinating insight into the deepest of questions: what might an alien actually look like' Lewis Dartnell, author of Origins

'If you don't want to be surprised by extraterrestrial life, look no further than this lively overview of the laws of evolution that have produced life on earth' Frans de Waal, author of Mama's Last Hug


  • I love The Zoologist's Guide to the Galaxy by Arik Kershenbaum. Although it sets out to be (and is) about alien life, what emerges is a wonderfully insightful sidelong look at Earthly biology
