How does the brain work? How different is a human brain from other creatures' brains? Is the human brain still evolving? In this fascinating book, Michael O'Shea provides a non-technical introduction to the main issues and findings in current brain research, and gives a sense of how neuroscience addresses questions about the relationship between the brain and the mind.

The Galápagos archipelago is often viewed as a last foothold of pristine nature. For 60 years, conservationists have worked to restore this evolutionary Eden after centuries of exploitation at the hands of pirates, whalers, and island settlers. This book tells the story of the islands' namesakes - the giant tortoises - as coveted food sources, objects of natural history, and famous icons of conservation and tourism. By doing so, it brings into stark relief the paradoxical, and impossible, goal of conserving species by trying to restore a past state of prehistoric evolution.

A spirited collection of essays by cutting-edge neuroscientists that irreverently explores the quirky and counter intuitive aspects of brain function. Neuroscientist David J. Linden approached leading brain researchers and asked each the same question: "What idea about brain function would you most like to explain to the world?" Their responses make up this one-of-a-kind collection of popular science essays that seeks to expand our knowledge of the human mind and its possibilities.

How did human minds become so different from those of other animals? What accounts for our capacity to understand the way the physical world works, to think ourselves into the minds of others, to gossip, read, tell stories about the past, and imagine the future? These questions are not new: they have been debated by philosophers, psychologists, anthropologists, evolutionists, and neurobiologists over the course of centuries. One explanation widely accepted today is that humans have special cognitive instincts.

This dynamic chronicle of the race to find the "missing links" between humans and apes transports readers into the highly competitive world of fossil hunting and into the lives of the ambitious scientists intent on pinpointing the dawn of humankind. The quest to find where and when the earliest human ancestors first appeared is one of the most exciting and challenging of all scientific pursuits.

Horses have a story to tell - one of resilience, sociability, and intelligence and of partnership with human beings. In The Horse, journalist and equestrienne Wendy Williams brings that story brilliantly to life. Williams chronicles the 56-million-year journey of horses as she visits with experts around the world, exploring what our biological affinities and differences can tell us about the bond between horses and humans and what our longtime companions might think and feel.

Our sense of smell - or olfaction as it is technically known - is our most enigmatic sense. It can conjure up memories, taking us back to very specific places and emotions, whilst powerful smells can induce strong feelings of hunger or nausea. In the animal kingdom smell can be used to find food, a mate, or a home; to sense danger; and to send and receive complex messages with other members of a species. Yet despite its fundamental importance in our mental life and in the existence of all animals, our scientific understanding of how smell works is limited.

Wilderness guide and lifelong Alaskan Bjorn Dihle weaves personal experience with historical and contemporary accounts to explore the world of brown bears - from encounters with the Lewis and Clark Expedition to frightening attacks including the famed death of Timothy Treadwell, the controversies related to bear hunting, the animal's place in native cultures, and the impacts on the species from habitat degradation and climate change.

Everywhere there are characteristics of animals that do not want to fit into the theory of evolution anywhere. And man? Are we really the most adapted life-form on this planet? Today, more and more scientists who contradict the previous theory of evolution speak out. The theory fits the changes within the species, but it can no longer be reconciled with the inner workings of the cell. Some other influence that has so far escaped us is affecting evolution. It is called "Intelligent Design." Intelligent planning is suspected behind this.

Revised, updated, and expanded with the latest interpretations and fossil discoveries, the second edition of Oceans of Kansas adds new twists to the fascinating story of the vast inland sea that engulfed central North America during the Age of Dinosaurs. Giant sharks, marine reptiles called mosasaurs, pteranodons, and birds with teeth all flourished in and around these shallow waters. Their abundant and well-preserved remains were sources of great excitement in the scientific community when first discovered in the 1860s and continue to yield exciting discoveries 150 years later.

Minding the Climate investigates this problem in the neuroscience of decision-making. Ann-Christine Duhaime, MD, points to the evolution of the human brain during eons of resource scarcity. The brain adapted to prioritize short-term survival over more uncertain long-term outcomes. But the resulting behavioral architecture is poorly suited to the present, when scarcity is a lesser concern and slow-moving challenges like environmental issues present the greatest danger.

In Life Between the Tides, Adam Nicolson investigates one of the most revelatory habitats on earth. Under his microscope, we see a prawn's head become a medieval helmet and a group of "winkles" transform into a Dickensian social scene, with mollusks munching on Stilton and glancing at their pocket watches. Or, rather, is a winkle more like Achilles, an ancient hero, throwing himself toward death for the sake of glory? For Nicolson, the world of the rockpools is infinite and as intricate as our own.

Enzymes are the astonishing tiny molecular machines that make life possible. Each one of these small proteins speeds up a single chemical reaction inside a living organism many millionfold. Working together, teams of enzymes carry out all the processes that collectively we recognize as life, from making DNA to digesting food. This Very Short Introduction explains the why and the how of speeding up these reactions - catalysis - before going on to reveal how we have evolved these catalysts of such extraordinary power and exquisite selectivity.

Morange covers everything from the first cell theory to the origins of the concept of ecosystems, and offers perspectives on areas that are often neglected by historians of biology, such as ecology, ethology, and plant biology. He highlights the contributions of technology, the important role of hypothesis and experimentation, and the cultural contexts in which some of the most breathtaking discoveries in biology were made. Unrivaled in scope and written by a world-renowned historian of science, A History of Biology is an ideal introduction for students and experts alike.

Florapedia is an eclectic A-Z compendium of botanical lore. With more than 100 enticing entries - on topics ranging from achlorophyllous plants that use a fungus as an intermediary to obtain nutrients from other plants to zygomorphic flowers that admit only the most select pollinators - this collection is a captivating journey into the realm of botany. Writing in her incomparably engaging style, Carol Gracie discusses remarkable plants from around the globe, botanical art and artists, early botanical explorers, ethnobotanical uses of plants, botanical classification, and more.

Susanne Schötz is hard at work on breaking the cat code. She is a professor at Lund University in Sweden, where a long-standing research program is proving that cats do actually use vocal communication-with each other and with their human caretakers. Understanding the vocal strategies used in human-cat communication will have profound implications for how we communicate with our pets and has the potential to improve the relationship between animals and humans within several fields, including animal therapy, veterinary medicine, and animal sheltering.

Supermarket produce sections bulging with a year-round supply of perfectly round, bright red-orange tomatoes have become all but a national birthright. But in Tomatoland, which is based on his James Beard Award-winning article, The Price of Tomatoes, investigative food journalist Barry Estabrook reveals the huge human and environmental cost of the $5 billion fresh tomato industry. Fields are sprayed with more than one hundred different herbicides and pesticides. Tomatoes are picked hard and green and artificially gassed until their skins acquire a marketable hue.

In 2010, scientists led by J. Craig Venter became the first to successfully create "synthetic life" - putting humankind at the threshold of the most important and exciting phase of biological research, one that will enable us to actually write the genetic code for designing new species to help us adapt and evolve for long-term survival. The science of synthetic genomics will have a profound impact on human existence, including chemical and energy generation, health, clean water and food production, environmental control, and possibly even our evolution.

As nature's largest and longest-lived creations, trees play an extraordinarily important role in our cities; they are living landmarks that define space, cool the air, soothe our psyches, and connect us to nature and our past. Jill Jonnes's Urban Forests tells the captivating stories of the founding mothers and fathers of urban forestry, in addition to those arboreal advocates presently using the latest technologies to illuminate the value of trees to public health and to our urban infrastructure.
