With predation and carnivory as catalysts, the first known eye appeared in a trilobite during the Cambrian explosion approximately 543 million years ago. This period was a crucible of evolution and teemed with anatomic creativity although the journey to formed vision actually began billions of years before that. The Cambrian period, however, spawned nearly all morphologic forms of the eye, followed by descent over hundreds of millions of years providing an unimaginable variety of eyes with at least ten different designs. Some eyes display spectacular creativity with mirror, scanning or telephoto optics. Some of these ocular designs are merely curiosities, while others offer the finest visual...
The authors—representing both ophthalmology and dermatology—have created the definitive reference on ocular manifestations of local and systemic skin diseases. This atlas includes more than 900 color photographs that show common diseases at various stages, not just in their most dramatic form. Readers can track the evolution of conditions from initial irritation and blemish through eruption to the secretion of pus. A glossary defines the many terms used by both the dermatologist and the ophthalmologist.

This book covers the way that all known types of eyes work, from their optics to the behaviour they guide. The ways that eyes sample the world in space and time are considered, and the evolutionary origins of eyes are discussed. This new edition incorporates discoveries made since the first edition published in 2001.
The Seerkind, a people who possess the power to make magic, have weaved themselves into a rug for safekeeping. Now, with the last human caretaker dead, a variety of humans vie for ownership of the rug.
"The evolution of the eye spans 3.75 billion years from single cell organisms with eyespots to Metazoa with superb camera style eyes. At least ten different ocular models have evolved independently into myriad optical and physiological masterpieces. The story of the eye reveals evolution's greatest triumph and sweetest gift. This book describes its journey"--Provided by publisher.
"Long ago in 1945 all the nice people in England were poor, allowing for exceptions," begins The Girls of Slender Means, Dame Muriel Spark's tragic and rapier-witted portrait of a London ladies' hostel just emerging from the shadow of World War II. Like the May of Teck Club itself—"three times window shattered since 1940 but never directly hit"—its lady inhabitants do their best to act as if the world were back to normal: practicing elocution, and jostling over suitors and a single Schiaparelli gown. The novel's harrowing ending reveals that the girls' giddy literary and amorous peregrinations are hiding some tragically painful war wounds. Chosen by Anthony Burgess as one of the Best Modern Novels in the Sunday Times of London, The Girls of Slender Means is a taut and eerily perfect novel by an author The New York Times has called "one of this century's finest creators of comic-metaphysical entertainment."

Winner, 2010 PROSE Award for Excellence in the Biological Sciences. Professional and Scholarly Publishing division of the Association of American Publishers In this unique book, Peter S. Ungar tells the story of mammalian teeth from their origin through their evolution to their current diversity. Mammal Teeth traces the evolutionary history of teeth, beginning with the very first mineralized vertebrate structures half a billion years ago. Ungar describes how the simple conical tooth of early vertebrates became the molars, incisors, and other forms we see in mammals today. Evolutionary adaptations changed pointy teeth into flatter ones, with specialized shapes designed to complement the corre...
