This book shows what can be achieved by combining insights from sensory physiology with anatomy, phylogeny and the fossil record across the widest range of organisms to document the evolution of a biological system. It demonstrates how the study of living forms can successfully be used to interpret fossil ones, and vice versa. The book's magnificent sweep is all-encompassing, and remarkably up-to-date for such a cross-disciplinary work. It's rare for one person to have such a broad background, but Schwab has achieved this, such that the work provides an example for future studies of the kind.

An astounding erudite and exciting visual description of eye evolution, something every inquisitive biologist, veterinarian, neuroscientist, or ophthalmologist should have in their library. This book contains 400 illustrations that define and refine the text providing a unique look at the how the eye was achieved. It is truly one of a kind.

Schwab's lavishly illustrated book documents the amazing proliferation of eyes across the animal kingdom, in all their variations and all their splendour, and it explains the pathways by which these eyes have evolved. Aimed at the non-specialist but intelligent reader, the book begins with the early evolution of life on earth, and sets the scene for the advent of eyes that took place some 500-600 million years ago (mya). By combining fossil evidence with information from extant "primitive" organisms, Schwab explains current ideas about the simple animals that were present during the Ediacaran period (around 600 mya), about the light-detection mechanisms and the genetic machinery that they possessed, and about the split of these primitive animals into two major divisions - comprising on the one hand most invertebrates and on the other hand our own line that led to vertebrates and mammals.
High on the agenda is the invention, around the time of the Cambrian explosion in body forms (more than 500 mya), and the subsequent re-invention, of the two radically different forms of eye: the camera-style eye (as we have) with a single lens, and the compound eye, with multiple repeated units each having its own lens or mirror. Using beautiful images, Schwab charts the myriad variations on these two themes that have been employed by countless species, extinct and extant, over the course of 500 million years of global experimentation, refinement, and rejection. The result is a stunning book that will serve both to introduce non-specialists to the concepts of evolution and eye evolution and also as a reference work for experts.

The evolution of the eye was unquestionably one of the most important innovations in the history of life. Ivan Schwab has synthesized a huge array of disparate information to provide us with an indispensable guide through the complexities of visual systems throughout the animal kingdom.

"Which leads to a just published book -- a most remarkable book -- that needs to be in the library of every school and college, and maybe in every household ...There aren't many books like this one, transformative books that provide a wondrous experience -- especially for young people -- just by turning the pages of mesmerizing illustrations of the evolution of the eyes that are looking at the book... A deep majestic event: human eyes looking at a book explaining the evolution of human eyes. (The only event that I know of with more majesty is the human brain contemplating its own evolution.)" -- Dan Agin, Huffington Post
"Evolution's Witness: How the Eyes Evolved
is an outstanding book. It can be highly recommended. Every neuroophthalmologist should strongly consider adding this book to their library. It would also be valuable for ophthalmologists, neurologists, and neurosurgeons interested in the field of evolution." -- Walter M. Jay, MD, Neuro-ophthalmology
