Book Description
A new vision is sweeping through ecological science: The dense web of dependencies that makes up an ecosystem has gained an added dimension-the dimension of time. Every field, forest, and park is full of living organisms adapted for relationships with creatures that are now extinct. In a vivid narrative, Connie Barlow shows how the idea of "missing partners" in nature evolved from isolated, curious examples into an idea that is transforming how ecologists understand the entire flora and fauna of the Americas. This fascinating book will enrich and deepen the experience of anyone who enjoys a stroll through the woods or even down an urban sidewalk. But this knowledge has a dark side too: Barlow's "ghost stories" teach us that the ripples of biodiversity loss around us now are just the leading edge of what may well become perilous cascades of extinction.

Book Description
Renowned paleoartist John Gurche brings the traditional techniques of figure drawing and anatomical art to the portrayal of our hominin ancestors. The result is a visual record of the evolving human form that feels alive in a way no scientific illustration could match. While science provides an underpinning to Gurche's art, his work's primary purpose is to forge an aesthetic connection to the hominins that preceded us on Earth, capturing their humanity. With essays by leading authorities, Lost Anatomies carries the story of human evolution from apes and early hominins; to Australopithecus; to archaic Homo sapiens, including Homo erectus; to derived Homo sapiens, including Neanderthals and other species that are our most recent ancestors.

Book Description
Sex is the queen of problems in evolutionary biology. Generations of researchers have investigated one of the last remaining evolutionary paradoxes: why sex exists at all. Given that sexual reproduction is costly from an evolutionary point of view, one could wonder why not all animals and plants reproduce asexually. Dozens of contemporary hypotheses attempt to explain the prevalence of sex and its advantages and predict the early extinction of fully asexual lineages. The major theme of this book is: what is the fate of animal and plant groups in which sex is lost? Initial chapters discuss theory behind asexual life: what major disadvantages do asexual groups have to face, what are the genetic and ecological consequences and what does this theory predict for more applied aspects of asexual life, for example in agricultural pests, diseases as well as in cultural crops such as grapes. Cases studies in many animals (focusing on both invertebrates and vertebrates) and plants reveal parallel, but also singularly novel adaptations to the absence of meiosis and syngamy. And last but not least, are asexuals really doomed to early extinction or do genuine ancient asexuals exist? This book assembles contributions from the most important research groups dealing with asexual evolution in eukaryotes. It is a milestone in research on parthenogenesis and will be useful to undergraduate as well as graduate students and to senior researchers in all fields of evolutionary biology, as the paradox of sex remains its queen of problems.

Book Description
Tis book, already translated into ten languages, may at frst sight appear to be just about honeybees and their biology. It c- tains, however, a number of deeper messages related to some of the most basic and important principles of modern biology. Te bees are merely the actors that take us into the realm of phys- ology, genetics, reproduction, biophysics and learning, and that introduce us to the principles of natural selection underlying the evolution of simple to complex life forms. Te book destroys the cute notion of bees as anthropomorphic icons of busy self-sacr -i fcing individuals and presents us with the reality of the colony as an integrated and independent being—a “superorganism”—with its own, almost eerie, emergent group intelligence. We are s- prised to learn that no single bee, from queen through drone to sterile worker, has the oversight or control over the colony. - stead, through a network of integrated control systems and fee- backs, and communication between individuals, the colony - rives at consensus decisions from the bottom up through a type of “swarm intelligence”. Indeed, there are remarkable parallels between the functional organization of a swarming honeybee colony and vertebrate brains.

Book Description
"A small change today can change our tomorrow. A small change 100 million years ago can change everything."No one really noticed when things started to change. Some animals vanished. Some new ones appeared. Then some things appeared that were monstrous. No one seemed to notice except Ben Cartwright and the other survivors of the hidden plateau in the depths of the Amazon Jungle. Only they were aware of the growing threat to the human race.While Andy Martin lived out his dreams by venturing north to witness the birth of the American continent and navigate a prehistoric inland sea of the Late Cretaceous, whatever he was doing was rippling forward to change our world. Every day brought new threats in the form of creatures that should have long been extinct, or newly evolved monstrosities that were from mankind's worst nightmares.The comet, Primordia, was returning and time was up. They had to go back and find Andy and stop him before mankind vanished from the face of the Earth.In the thrilling 3rd installment of the blockbusting PRIMORDIA series, Greig Beck explores a frightening world where evolution has gone wild, while also taking us further into the prehistoric Cretaceous jungle and oceans, to a time in which mankind was never meant to exist.

Book Description
Of what use is evolutionary science to society? Can evolutionary thinking provide us with the tools to better understand and even make positive changes to the world? Addressing key questions about the development of evolutionary thinking, this book explores the interaction between evolutionary theory and its practical applications. Featuring contributions from leading specialists, Pragmatic Evolution highlights the diverse and interdisciplinary applications of evolutionary thinking: their potential and limitations. The fields covered range from palaeontology, genetics, ecology, agriculture, fisheries, medicine, neurobiology, psychology and animal behaviour; to information technology, education, anthropology and philosophy. Detailed examples of useful and current evolutionary applications are provided throughout. An ideal source of information to promote a better understanding of contemporary evolutionary science and its applications, this book also encourages the continued development of new opportunities for constructive evolutionary applications across a range of fields.

Book Description
We all have our off days. Why should Evolution be any different? Maybe Evolution got carried away with an idea that was just a little too crazy—like having the Regal Horned Lizard defend itself by shooting three-foot streams of blood from its eyes. Or maybe Evolution ran out of steam (Memo to Evolution: The Irrawaddy Dolphin looks like a prototype that should have been left on the drawing board). Or maybe Evolution was feeling cheeky—a fish with hands? Joke’s on you, Red Handfish! Or maybe Evolution simply goofed up: How else to explain the overgrown teeth of the babirusas that curl backward over their face? Oops. Mara Grunbaum is a very smart, very funny science writer who celebrates the best—or, really, the worst—of Evolution’s blunders. Here are more than 100 outlandish mammals, reptiles, insects, fish, birds, and other creatures whose very existence leaves us shaking our heads and muttering WTF?! Ms. Grunbaum’s especially brilliant stroke is to personify Evolution as a well-meaning but somewhat oblivious experimenter whose conversations with a skeptical narrator are hilarious. For almost 4 billion years, Evolution has produced a nonstop parade of inflatable noses, bizarre genitalia, and seriously awkward necks. What a comedian!

Book Description
Biology was forged into a single, coherent science only within living memory. In this volume the thinkers responsible for the "modern synthesis" of evolutionary biology and genetics come together to analyze that remarkable event. In a new Preface, Ernst Mayr calls attention to the fact that scientists in different biological disciplines varied considerably in their degree of acceptance of Darwin's theories. Mayr shows us that these differences were played out in four separate periods: 1859 to 1899, 1900 to 1915, 1916 to 1936, and 1937 to 1947. He thus enables us to understand fully why the synthesis was necessary and why Darwin's original theory--that evolutionary change is due to the combination of variation and selection--is as solid at the end of the twentieth century as it was in 1859.
