Just behind the iris Studies on the vertebrate lens. book the lens, a transparent, elastic oval disc that, with the aid of ciliary muscles, can alter the curvature of the lens and bend light rays to focus an image on the retina. In terrestrial vertebrates the cornea actually does most of the bending of light rays, whereas the lens adjusts focus for near and far objects.

The omission of these studies is a lost opportunity and limits the scope of the volume. Despite this limitation, the publication of well-written and nearly comprehensive book on long-term studies of vertebrate cooperative breeding is timely and important.

The ocelloid looks somewhat like a vertebrate’s lens-like eyeball, except it’s actually a chloroplast that’s been modified. The vertebrate eye was one of the classic embryologic models in the early s. Within the last decade of the 20th century, a return to some of the old questions with the new approaches has put eye development back into the limelight.
