Written by an author team, including a Noble Prize winner, this text presents the integration of Mendelian and molecular principles, providing students with the links between early genetics understanding and the molecular discoveries that have changed the way the field of genetics is viewed.

    A spider lassoes its prey. A beetle persuades a bee to care for its young. This beautifully illustrated book by veteran naturalist Sir David Attenborough offers a rare glimpse into the secret life of invertebrates, the world's tiniest--and most fascinating--creatures.Small by virtue of their lack of backbones, this group of living things plays a surprisingly large role in the evolutionary cycle. These diverse creatures (more than one million species are believed to exist) roamed the earth before us and will still be here when we have gone. They are the pollinators, cleaners, and recyclers of life on earth. Without them, we would not last long.Attenborough has studied and enjoyed these diminutive beings since he was a schoolboy in the Leicestershire countryside of England. Life in the Undergrowth, part of his innovative series on natural history topics, looks at invertebrates the world over: their arrival on land and mastery of every habitat, and their fantastic variety of hunting, mating, and highly organized social behaviors.Adults are prejudiced against insects--handicapped by their ignorance and fears and limited by their size and vision. Children, who are closer to insects in size, notice and enjoy the tiny creatures.In this companion book to the Animal Planet television program, Attenborough shares his childlike curiosity for invertebrates, taking us down wormholes and into insect homes for an up-close-and-personal look at their habitats. As the biblical book of Proverbs implores: Go to the ant, thou sluggard: consider her ways and be wise. David Attenborough does go. It is worth going with him.

    Nature’s many innovations—some uncannily perfect—call for natural principles that accelerate life’s ability to innovate.”Darwin’s theory of natural selection explains how useful adaptations are preserved over time. But the biggest mystery about evolution eluded him. As genetics pioneer Hugo de Vries put it, “natural selection may explain the survival of the fittest, but it cannot explain the arrival of the fittest.”Can random mutations over a mere 3.8 billion years really be responsible for wings, eyeballs, knees, camouflage, lactose digestion, photosynthesis, and the rest of nature’s creative marvels? And if the answer is no, what is the mechanism that explains evolution’s speed and efficiency?In Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over fifteen years of research to present the missing piece in Darwin's theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take.Consider the Arctic cod, a fish that lives and thrives within six degrees of the North Pole, in waters that regularly fall below 0 degrees. At that temperature, the internal fluids of most organisms turn into ice crystals. And yet, the arctic cod survives by producing proteins that lower the freezing temperature of its body fluids, much like antifreeze does for a car’s engine coolant. The invention of those proteins is an archetypal example of nature’s enormous powers of creativity. Meticulously researched, carefully argued, evocatively written, and full of fascinating examples from the animal kingdom, Arrival of the Fittest offers up the final puzzle piece in the mystery of life’s rich diversity.

    Though his theory could explain many facts, Darwin knew that there was a significant event in the history of life that his theory did not explain. During this event, the Cambrian explosion, many animals suddenly appeared in the fossil record without apparent ancestors in earlier layers of rock. In Darwin's Doubt, Stephen C. Meyer tells the story of the mystery surrounding this explosion of animal life-a mystery that has only intensified. Meyer argues that the mysterious features of the Cambrian event are best explained by intelligent design.

    But it was not reels of wool or bales of cotton that awaited him, but plants and seeds…Over the next forty years, Bartram would send hundreds of American species to England, where Collinson was one of a handful of men who would foster a national obsession and change the gardens of Britain forever, introducing lustrous evergreens, fiery autumn foliage and colourful shrubs. They were men of wealth and taste but also of knowledge and experience like Philip Miller, author of the bestselling Gardeners Dictionary, and the Swede Carl Linnaeus, whose standardised botanical nomenclature popularised botany as a genteel pastime for the middle-classes; and the botanist-adventurer Joseph Banks and his colleague Daniel Solander who both explored the strange flora of Tahiti and Australia on the greatest voyage of discovery of modern times, Captain Cook’s Endeavour.This is the story of these men – friends, rivals, enemies, united by a passion for plants – whose correspondence, collaborations and squabbles make for a riveting human tale which is set against the backdrop of the emerging empire, the uncharted world beyond and London as the capital of science. From the scent of the exotic blooms in Tahiti and Botany Bay to the gardens at Chelsea and Kew, and from the sounds and colours of the streets of the City to the staggering vistas of the Appalachian mountains, The Brother Gardeners tells the story of how Britain became a nation of gardeners.

    In 1992, in a remote mountain range, a team of scientists discovered the remains of an unusual animal with exquisite long horns. It turned out to be a living species new to Western science -- a saola, the first large land mammal discovered in fifty years. Rare then and rarer now, a live saola had never been glimpsed by a Westerner in the wild when Pulitzer Prize finalist and nature writer William deBuys and conservation biologist William Robichaud set off to search for it in central Laos. Their team endured a punishing trek up and down white-water rivers and through mountainous terrain ribboned with the snare lines of armed poachers who roamed the forest, stripping it of wildlife. In the tradition of Bruce Chatwin, Colin Thubron, and Peter Matthiessen, The Last Unicorn chronicles deBuys's journey deep into one of the world's most remote places. It's a story rich with the joys and sorrows of an expedition into undiscovered country, pursuing a species as rare and elusive as the fabled unicorn. As is true with the quest for the unicorn, in the end the expedition becomes a search for something more: the essence of wildness in nature, evidence that the soul of a place can endure, and the transformative power of natural beauty.

    The idea that animals had feelings was either dismissed or considered heresy. Today, that’s all changing. New scientific studies of animal behavior reveal perceptions, intelligences, awareness and social skills that would have been deemed fantasy a generation ago. The implications make our troubled relationship to animals one of the most pressing moral issues of our time. Jonathan Balcombe, animal behaviorist and author of the critically acclaimed Pleasurable Kingdom, draws on the latest research, observational studies and personal anecdotes to reveal the full gamut of animal experience—from emotions, to problem solving, to moral judgment. Balcombe challenges the widely held idea that nature is red in tooth and claw, highlighting animal traits we have disregarded until now: their nuanced understanding of social dynamics, their consideration for others, and their strong tendency to avoid violent conflict. Did you know that dogs recognize unfairness and that rats practice random acts of kindness? Did you know that chimpanzees can trounce humans in short-term memory games? Or that fishes distinguish good guys from cheaters, and that birds are susceptible to mood swings such as depression and optimism? With vivid stories and entertaining anecdotes, Balcombe gives the human pedestal a strong shake while opening the door into the inner lives of the animals themselves.
