A tour of evolution’s most inventive—and essential—creations: animal genitalia Forget opposable thumbs and canine teeth: the largest anatomical differences between humans and chimps are found below the belt. In Nature’s Nether Regions, ecologist and evolutionary biologist Menno Schilthuizen invites readers to discover the wondrous diversity of animalian reproductive organs. Schilthuizen packs this delightful read with astonishing scientific insights while maintaining an absorbing narrative style reminiscent of Mary Roach and Jerry Coyne. With illustrations throughout and vivid field anecdotes—among them laser surgery on a fruit fly’s privates and a snail orgy—Nature’s Nether Regions is a celebration of life in all shapes and sizes.

"What's the easiest way to tell species apart? Check their genitals. Researching private parts was long considered taboo, but scientists are now beginning to understand that the wild diversity of sex organs across species can tell us a lot about evolution. Menno Schilthuizen invites readers to join him as he uncovers the ways the shapes and functions of genitalia have been molded by complex Darwinian struggles: penises that have lost their spines but evolved appendages to displace sperm; female orgasms that select or reject semen from males, in turn subtly modifying the females' genital shape. We learn why spiders masturbate into miniature webs, discover she dungflies that store sperm from attractive males in their bellies, and see how, when it comes to outlandish appendages and bizarre behaviors, humans are downright boring. Nature's Nether Regions joyfully demonstrates that the more we learn about the multiform private parts of animals, the more we understand our own unique place in the great diversity of life."--Publisher description.

*Carrion crows in the Japanese city of Sendai have learned to use passing traffic to crack nuts. *Lizards in Puerto Rico are evolving feet that better grip surfaces like concrete. *Europe’s urban blackbirds sing at a higher pitch than their rural cousins, to be heardover the din of traffic. How is this happening? Menno Schilthuizen is one of a growing number of “urban ecologists” studying how our manmade environments are accelerating and changing the evolution of the animals and plants around us. In Darwin Comes to Town, he takes us around the world for an up-close look at just how stunningly flexible and swift-moving natural selection can be. With human populations growing, we’re having an increasing impact on global ecosystems, and nowhere do these impacts overlap as much as they do in cities. The urban environment is about as extreme as it gets, and the wild animals and plants that live side-by-side with us need to adapt to a whole suite of challenging conditions: they must manage in the city’s hotter climate (the “urban heat island”); they need to be able to live either in the semidesert of the tall, rocky, and cavernous structures we call buildings or in the pocket-like oases of city parks (which pose their own dangers, including smog and free-rangingdogs and cats); traffic causes continuous noise, a mist of fine dust particles, and barriers to movement for any animal that cannot fly or burrow; food sources are mainly human-derived. And yet, as Schilthuizen shows, the wildlife sharing these spaces with us is not just surviving, but evolving ways of thriving. Darwin Comes toTown draws on eye-popping examples of adaptation to share a stunning vision of urban evolution in which humans and wildlife co-exist in a unique harmony. It reveals that evolution can happen far more rapidly than Darwin dreamed, while providing a glimmer of hope that our race toward over population might not take the rest of nature down with us.

This rambunctious first novel by the author of the bestselling Corelli's Mandolin is set in an impoverished, violent, yet ravishingly beautiful country somewhere in South America. When the haughty Dona Constanza decides to divert a river to fill her swimming pool, the consequences are at once tragic, heroic, and outrageously funny. "Walks a precarious edge between slapstick and pathos, never once losing its balance."--Washington Post Book World.

If you have ever wondered why women always bite your head off or why one guy gets all the girls, if you have ever pondered why some men bring you balloons while others leave you their genitals, then Dr Tatiana's Sex Advice to All Creation is the book for you. It explains all this and much more. It discloses the best time to have a sex change, how to have a virgin birth, when to seduce your sisters or eat your lover. Quirky and brilliant, it takes as its starting point all creatures great and small worried about their bizarre sex lives, and the letters they write to the wise Dr Tatiana, the only agony aunt in all creation with a prodigious knowledge of both natural history and evolutionary biology.

This timely book revisits cryptic female choice in arthropods, gathering detailed contributions from around the world to address key behavioral, ecological and evolutionary questions. The reader will find a critical summary of major breakthroughs in taxon-oriented chapters that offer many new perspectives and cases to explore and in many cases unpublished data. Many groups of arthropods such as spiders, harvestmen, flies, moths, crickets, earwigs, beetles, eusocial insects, shrimp and crabs are discussed. Sexual selection is currently the focus of numerous and controversial theoretical and experimental studies. Selection in mating and post-mating patterns can be shaped by several different mechanisms, including sperm competition, extreme sexual conflict and cryptic female choice. Discrimination among males during or after copulation is called cryptic female choice because it occurs after intromission, the event that was formerly used as the definitive criterion of male reproductive success and is therefore usually difficult to detect and confirm. Because it sequentially follows intra- and intersexual interactions that occur before copulation, cryptic female choice has the power to alter or negate precopulatory sexual selection. However, though female roles in biasing male paternity after copulation have been proposed for a number of species distributed in many animal groups, cryptic female choice continues to be often underestimated. Furthermore, in recent years the concept of sexual conflict has been frequently misused, linking sexual selection by female choice irrevocably and exclusively with sexually antagonistic co-evolution, without exploring other alternatives. The book offers an essential source of information on how two fields, selective cooperation and individual sex interests, work together in the context of cryptic female choice in nature, using arthropods as model organisms. It is bound to spark valuable discussions among scientists working in evolutionary biology across the world, motivating new generations to unveil the astonishing secrets of sexual biology throughout the animal kingdom.

A major new look at the evolution of mating decisions in organisms from protozoans to humans The popular consensus on mate choice has long been that females select mates likely to pass good genes to offspring. In Mate Choice, Gil Rosenthal overturns much of this conventional wisdom. Providing the first synthesis of the topic in more than three decades, and drawing from a wide range of fields, including animal behavior, evolutionary biology, social psychology, neuroscience, and economics, Rosenthal argues that "good genes" play a relatively minor role in shaping mate choice decisions and demonstrates how mate choice is influenced by genetic factors, environmental effects, and social interactions. Looking at diverse organisms, from protozoans to humans, Rosenthal explores how factors beyond the hunt for good genes combine to produce an endless array of preferences among species and individuals. He explains how mating decisions originate from structural constraints on perception and from nonsexual functions, and how single organisms benefit or lose from their choices. Both the origin of species and their fusion through hybridization are strongly influenced by direct selection on preferences in sexual and nonsexual contexts. Rosenthal broadens the traditional scope of mate choice research to encompass not just animal behavior and behavioral ecology but also neurobiology, the social sciences, and other areas. Focusing on mate choice mechanisms, rather than the traits they target, Mate Choice offers a groundbreaking perspective on the proximate and ultimate forces determining the evolutionary fate of species and populations.
