When Richard Goldschmidt' coined the term "intersexuality" in 1915, he intended it to apply to normally dioecious species which exhibit some kind of mixture between male and female characters. However, as knowledge of the bewildering variability present in the sexual orga nization of members of the animal kingdom has increased, the original meaning of the word has changed. Today many authors define inter sexuality as "the presence of both male and female characteristics, or of intermediate sexual characteristics, in a single individual".2 This more extensive and widely accepted concept justifies the title of our book •. Among all the anatomical and physiological features of living organisms the reproductive system has a unique importance for the perpetuation of the species. Conversely, reproductive processes are of little or no account for the viability of the individual. Therefore, within the framework of general biology reproduction has all too often been looked at solely from the point of view of genetics. Lively discussions about genotypic versus phenotypic sex determination long dominated the sci entific literature on sexuality in animals; this one-sided emphasis has tended to obscure many important facets of an organism's ability to reproduce. Recent developments in current biological research have brought the classic problem of sex differentiation into focus again, and the rapid progress being made in comparative endocrinology has added a new di mension to the study of reproductive biology.

The remarkable and unique ways that male and female animals play out gender roles in nature While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of many other animals. For instance, the male garden spider spontaneously dies after mating with a female more than fifty times his size. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist? Introducing readers to important discoveries in animal behavior and evolution, Odd Couples explores some of the most extraordinary sexual differences in the animal world. Daphne Fairbairn uncovers the unique and bizarre characteristics of these remarkable species and the special strategies they use to maximize reproductive success. Fairbairn also considers humans and explains that although we are keenly aware of our own sexual differences, they are unexceptional within the vast animal world. Looking at some of the most amazing creatures on the planet, Odd Couples sheds astonishing light on what it means to be male or female in the animal kingdom.

The most important aspect of evolution, from a philosophical viewpoint, is the rise of complex, advanced creatures from simple, primitive ones. This "vertical" dimension of evolution has been downplayed in both the specialist and popular literature on evolution, in large part because it was in the past associated with unsavory political views. The avoidance of evolution's vertical dimension has, however, left evolutionary biology open to the perception, from outside, that it deals merely with the diversification of rather similar creatures, all at the same level of "advancedness" from a common ancestor—for example, the classic case studies of finches with different beaks or moths of different colors. The latest incarnation of creationism, dubbed intelligent design (or ID), has taken advantage of this situation. It portrays an evolutionary process that is constantly guided—especially in its upward direction—by the hand of an unseen Creator, who is able to ensure that it ends up producing humans. Creatures of Accident attacks the antiscience ID worldview, mainly by building a persuasive picture of how "unaided" evolution produces advanced creatures from simple ones by an essentially accidental process. Having built this picture, in the final chapter the book reflects on its religious implications.

Throughout his life photographer Jim Naughten has been fascinated with the natural world. As a child, he collected fossils he found near his home in Dover. Now a renowned photographer, Naughten has started to experiment with stereography and has turned to his boyhood interest, gaining access to the archives of some of the world's most prestigious natural history museums. This gorgeously produced book contains fifty images of marine life, reptiles, mammals, birds and primates photographed expressly for viewing through a stereoscope, which is included with the book. Stereoscopy was invented in 1839 to study and explain binocular vision. Having two eyes allows humans to determine distance and depth and stereoscopy shows a left- and right-eye view from a slightly different angle, as we see things in day-to-day life. Looking through the stereo viewer, readers will see the specimens as three-dimensional objects. As the images jump off the page, their incredible details become apparent-delicate bat wings, the spiraling skeleton of a python, the almost mythic form of a leafy sea dragon.A foreword by Martin Barnes of the Victoria and Albert Museum, London offers an assessment of the work while essays on the specimens themselves and the history of stereoscopy provide rich background to this photographic technology, and to Naughten's achievement in bringing to life a world that seamlessly melds the past and present.

Creatures from the animal kingdom represented in exquisite jewelry by renowned masters Cartier, Bulgari, Tiffany & Co., JAR, Belperron, David Webb, Schlumberger, Boucheron, and many other brilliant jewelers. Many of the most imaginative designs by the world's great jewelry houses and artisans take inspiration from the animal kingdom. From Cartier's iconic panthers to Bulgari's snakes and JAR's butterflies, these spectacular objects dripping with precious stones are akin to wearable art. Beautiful Creatures depicts some of the most spectacular beasts ever transformed into sparkling treasures and accompanies a forthcoming special exhibition in the American Museum of Natural History's Allison and Roberto Mignone Halls of Gems and Minerals. The 120 pieces featured date from the mid-1800s to the present, representing species from the realms of land, air, and water. Gorgeous studio photography of the jewelry is complemented by images of iconic personalities, including Elizabeth Taylor, Twiggy, and the Duchess of Windsor wearing famous animal- inspired jewels. Guest curator Marion Fasel relays the stories behind the individual pieces through entertaining anecdotes and reveals the colorful histories and fascinating symbolism of these remarkable creatures in precious gems and metals that intrigue and delight and that we never tire of wearing.
