News of both the Ice Man's discovery and his age, which was put at over five thousand years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative of a man who died thousands of years ago?In The Seven Daughters of Eve, he gives us a firsthand account of his research into a remarkable gene, which passes undiluted from generation to generation through the maternal line. After plotting thousands of DNA sequences from all over the world, Sykes found that they clustered around a handful of distinct groups. Among Europeans and North American Caucasians, there are, in fact, only seven. This conclusion was staggering: almost everyone of native European descent, wherever they may live throughout the world, can trace their ancestry back to one of seven women, the Seven Daughters of Eve.Naming them Ursula, Xenia, Helena, Velda, Tara, Katrine, and Jasmine, Sykes has created portraits of their disparate worlds by mapping the migratory patterns followed by millions of their ancestors. In reading the stories of these seven women, we learn exactly how our origins can be traced, how and where our ancient genetic ancestors lived, and how we are each living proof of the almost indestructible strands of DNA, which have survived over so many thousands of years. Indeed, The Seven Daughters of Eve is filled with dramatic stories: from Sykes's identification, using DNA samples from two living relatives, of the remains of Tsar Nicholas and Tsaress Alexandra, to the Caribbean woman whose family had been sold into slavery centuries before and whose ancestry Sykes was able to trace back to the Eastern coast of central Africa. Ultimately, Sykes's investigation reveals that, as a race, what humans have in common is more deeply embedded than what separates us.

    But as Ocean Guardian founder William McKeever reveals, sharks are evolutionary marvels essential to maintaining a balanced ecosystem. We can learn much from sharks, he argues, and our knowledge about them continues to grow. The first book to reveal in full the hidden lives of sharks, Emperors of the Deep examines four species—Mako, Tiger, Hammerhead, and Great White—as never before, and includes fascinating details such as:Sharks are 50-million years older than trees;Sharks have survived five extinction level events, including the one that killed off the dinosaurs;Sharks have electroreception, a sixth-sense that lets them pick up on electric fields generated by living things;Sharks can dive 4,000 feet below the surface;Sharks account for only 6 human fatalities per year, while humans kill 100 million sharks per year.McKeever goes back through time to probe the shark’s pre-historic secrets and how it has become the world’s most feared and most misunderstood predator, and takes us on a pulse-pounding tour around the world and deep under the water’s surface, from the frigid waters of the Arctic Circle to the coral reefs of the tropical Central Pacific, to see sharks up close in their natural habitat. He also interviews ecologists, conservationists, and world-renowned shark experts, including the founders of Greenpeace’s Rainbow Warrior, the head of the Massachusetts Shark Research Program, and the self-professed “last great shark hunter.”At once a deep-dive into the misunderstood world of sharks and an urgent call to protect them, Emperors of the Deep celebrates this wild species that hold the key to unlocking the mysteries of the ocean—if we can prevent their extinction from climate change and human hunters.

    The answers will surprise and delight you as Alexandra Horowitz, a cognitive scientist, explains how dogs perceive their daily worlds, each other, and that other quirky animal, the human.Temple Grandin meets Stephen Pinker in this engaging and informative look at what goes on inside the minds of dogs—from a cognitive scientist with a background at The New Yorker.With more than 52 million pet dogs in America today, it’s clear we are a nation of unabashed dog-lovers. Yet the relationship between dogs and humans remains a fascinating mystery, as no one really knows what goes on in the canine mind. Now, in Inside of a Dog, Alexandra Horowitz fuses her perspectives as both scientist and dog-owner to deliver a fresh look at the world of dogs—as seen from the animal’s point of view. Inspired by her years of living with her own dog, Pumpernickel, who was a constant source of delight and mystery, Horowitz’s mind became filled with questions and ideas. In crisp, clear prose, she draws on her research in the field of dog cognition to give readers a sense of a dog’s perceptual and cognitive abilities—and paints a picture of what the canine experience is like. Horowitz’s own scientific journey, and the insights she uncovered, allowed her to understand her dog better and appreciate her more.Containing up-to-the minute research and providing many moments of dog-behavior recognition, this lively and absorbing book helps dog owners to see their best friend’s behavior in a different, and revealing light, allowing them to understand their pets and enjoy their company even more.

    They have brains that are huge for their body size and exhibit an avian kind of eloquence. They mate for life and associate with relatives and neighbors for years. And because they often live near people—in our gardens, parks, and cities—they are also keenly aware of our peculiarities, staying away from and even scolding anyone who threatens or harms them and quickly learning to recognize and approach those who care for and feed them, even giving them numerous, oddly touching gifts in return. With his extraordinary research on the intelligence and startling abilities of corvids—crows, ravens, and jays—scientist John Marzluff teams up with artist-naturalist Tony Angell to tell amazing stories of these brilliant birds in Gifts of the Crow. With narrative, diagrams, and gorgeous line drawings, they offer an in-depth look at these complex creatures and our shared behaviors. The ongoing connection between humans and crows—a cultural coevolution—has shaped both species for millions of years. And the characteristics of crows that allow this symbiotic relationship are language, delinquency, frolic, passion, wrath, risk-taking, and awareness—seven traits that humans find strangely familiar. Crows gather around their dead, warn of impending doom, recognize people, commit murder of other crows, lure fish and birds to their death, swill coffee, drink beer, turn on lights to stay warm, design and use tools, use cars as nutcrackers, windsurf and sled to play, and work in tandem to spray soft cheese out of a can. Their marvelous brains allow them to think, plan, and reconsider their actions. With its abundance of funny, awe-inspiring, and poignant stories, Gifts of the Crow portrays creatures who are nothing short of amazing. A testament to years of painstaking research and careful observation, this fully illustrated, riveting work is a thrilling look at one of nature’s most wondrous creatures.

    Since reptiles are cold-blooded creatures, most humans don't instinctively understand their requirements the way they understand the needs of a cat or dog. Herp expert Philippe de Vosjoli and his team of veterinarians and authors seek to make keepers confident in their ability to properly care for their bearded dragons through this most informative book. A key component of caring for bearded dragons, according to the authors, is recognizing that their needs change as they develop. De Vosjoli states in the introduction to the book, "Looking at the life stages of bearded dragons also made [the authors] aware that, like humans, they undergo changes in growth and behavior, which may require the dedicated owner to make adjustments in husbandry (and general care) to meet the needs of each life style." The Bearded Dragon Manual is the first book to present this information that is so critical to the proper maintenance of these very popular reptiles.Colorfully illustrated, The Bearded Dragon Manual provides chapter-length coverage on the following topics: selecting a dragon, making a home for a dragon, heating and lighting, diet and feeding management, and behavior. The feeding chapter, which includes as age-by-age guide to nutrition, was co-written with veterinarian Dr. Susan Donoghue. A chapter on breeding discusses strategies for breeding dragons, requirements, conditioning, incubation, and potential problems encountered. Lizard vet extraordinaire Dr. Roger Klingenberg has written a chapter on recognizing and treating bearded dragon diseases, in which he discusses how to recognize a sick dragon, various internal and external parasites, nutritional disorders as well as kidney disease, prolapses, egg-binding, respiratory infections, and eye problems. The chapter concludes with a four-page chart for troubleshooting health problems. Herb expert Jerry Cole has provided a special chapter on frilled dragons, an agamid similar to the bearded dragon that has attracted many bearded dragon fans. Appendices and index included.

    And yet there is one creature that is thriving in this seasick environment: the beautiful, dangerous, and now incredibly numerous jellyfish. As foremost jellyfish expert Lisa-ann Gershwin describes in Stung!, the jellyfish population bloom is highly indicative of the tragic state of the world’s ocean waters, while also revealing the incredible tenacity of these remarkable creatures. Recent documentaries about swarms of giant jellyfish invading Japanese fishing grounds and summertime headlines about armadas of stinging jellyfish in the Mediterranean and Chesapeake are only the beginning—jellyfish are truly taking over the oceans. Despite their often dazzling appearance, jellyfish are simple creatures with simple needs: namely, fewer predators and competitors, warmer waters to encourage rapid growth, and more places for their larvae to settle and grow. In general, oceans that are less favorable to fish are more favorable to jellyfish, and these are the very conditions that we are creating through mechanized trawling, habitat degradation, coastal construction, pollution, and climate change. Despite their role as harbingers of marine destruction, jellyfish are truly enthralling creatures in their own right, and in Stung!, Gershwin tells stories of jellyfish both attractive and deadly while illuminating many interesting and unusual facts about their behaviors and environmental adaptations. She takes readers back to the Proterozoic era, when jellyfish were the top predator in the marine ecosystem—at a time when there were no fish, no mammals, and no turtles; and she explores the role jellies have as middlemen of destruction, moving swiftly into vulnerable ecosystems. The story of the jellyfish, as Gershwin makes clear, is also the story of the world’s oceans, and Stung! provides a unique and urgent look at their inseparable histories—and future.
