Evolution's Witness chronicles the evolution of the eye beginning with the initial cellular acquisition of photoreceptive molecules as long as 3.75 billion years ago. This well-illustrated book traces the development of simple, complex compound and camera-style eyes including description of more than ten forms of ocular design. Life has existed on earth an unfathomable length of time accompanied by changing climate and geography, and the evolution of the eye is described in that context. Eyes evolved independently perhaps as many as forty times, and these are reviewed in this text. Each of the forty or so independently evolved eyes has adapted to its niche, and fitting its owner's ecology perfectly. Evolution's greatest gift.
