Evolution's Witness

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 descriptions of more than ten forms of ocular design. Over time 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, fitting its owner's ecology perfectly.
