Book Description
Footprints is about an evolution revolution, the non-living world to the living tiny organisms of earliest Earth. each striving to have enough precious time to evolve so they might survive long enough to resist the effects of a changing world. And, yes - it is a story about Dinosaurs. But the story - being about evolution - has an unhappy ending for the great Dinosaurs of the Cretaceous. For what is surely natural reasons, as well as self-imposed doom by the creatures themselves, they fell fate to Extinction - just had many plants and animals had almost 200 million years earlier. This is not just the story of Dinosaurs and their extinction: all of the biological world is subject to - and ultimately succumbs to - demise through the processes of environment and nature. Today the possibilities of extinction are greatest because of the introduction of the newest form of life on Earth - humans - who have the capability of altering an otherwise natural progression of this world we live on.

Book Description
The book draws on the evidence of landscape archaeology, palaeoenvironmental studies, ethnohistory and animal tracking to address the neglected topic of how we identify and interpret past patterns of movement in the landscape. It challenges the pessimism of previous generations which regarded prehistoric routes such as hollow ways as generally undatable. The premise is that archaeologists tend to focus on ‘sites’ while neglecting the patterns of habitual movement that made them part of living landscapes. Evidence of past movement is considered in a multi-scalar way from the individual footprint to the long distance path including the traces created in vegetation by animal and human movement. It is argued that routes may be perpetuated over long timescales creating landscape structures which influence the activities of subsequent generations. In other instances radical changes of axes of communication and landscape structures provide evidence of upheaval and social change. Palaeoenvironmental and ethnohistorical evidence from the American North West coast sets the scene with evidence for the effects of burning, animal movement, faeces deposition and transplantation which can create readable routes along which are favoured resources. Evidence from European hunter-gatherer sites hints at similar practices of niche construction on a range of spatial scales. On a local scale, footprints help to establish axes of movement, the locations of lost settlements and activity areas. Wood trackways likewise provide evidence of favoured patterns of movement and past settlement location. Among early farming communities alignments of burial mounds, enclosure entrances and other monuments indicate axes of communication. From the middle Bronze Age in Europe there is more clearly defined evidence of trackways flanked by ditches and fields. Landscape scale survey and excavation enables the dating of trackways using spatial relationships with dated features and many examples indicate long-term continuity of routeways. Where fields flank routeways a range of methods, including scientific approaches, provide dates. Prehistorians have often assumed that Ridgeways provided the main axes of early movement but there is little evidence for their early origins and rather better evidence for early routes crossing topography and providing connections between different environmental zones. The book concludes with a case study of the Weald of South East England which demonstrates that some axes of cross topographic movement used as droveways, and generally considered as early medieval, can be shown to be of prehistoric origin. One reason that dryland routes have proved difficult to recognise is that insufficient attention has been paid to the parts played by riverine and maritime longer distance communication. It is argued that understanding the origins of the paths we use today contributes to appreciation of the distinctive qualities of landscapes. Appreciation will help to bring about effective strategies for conservation of mutual benefit to people and wildlife by maintaining and enhancing corridors of connectivity between different landscape zones including fragmented nature reserves and valued places. In these ways an understanding of past routeways can contribute to sustainable landscapes, communities and quality of life

Book Description
Humans are mammals. Most of us appreciate that at some level. But what does it mean for us to have more in common with a horse and an elephant than we do with a parrot, snake or frog? After a misdirected football left new father Liam Drew clutching a uniquely mammalian part of his anatomy, he decided to find out more. Considering himself as a mammal first and a human second, Liam delves into ancient biological history to understand what it means to be mammalian. In his humorous and engaging style, Liam explores the different characteristics that distinguish mammals from other types of animals. He charts the evolution of milk, warm blood and burgeoning brains, and examines the emergence of sophisticated teeth, exquisite ears, and elaborate reproductive biology, plus a host of other mammalian innovations. Entwined are tales of zoological peculiarities and reflections on how being a mammal has shaped the author's life. I, Mammal is a history of mammals and their ancestors and of how science came to grasp mammalian evolution. And in celebrating our mammalian-ness, Liam Drew binds us a little more tightly to the five and a half thousand other species of mammal on this planet and reveals the deep roots of many traits humans hold dear.

Book Description
ONE OF THE NEW YORK TIMES BOOK REVIEW'S 10 BEST BOOKS OF THE YEAR A major book about the future of the world, blending intellectual and natural history and field reporting into a powerful account of the mass extinction unfolding before our eyes Over the last half a billion years, there have been five mass extinctions, when the diversity of life on earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In The Sixth Extinction, two-time winner of the National Magazine Award and New Yorker writer Elizabeth Kolbert draws on the work of scores of researchers in half a dozen disciplines, accompanying many of them into the field: geologists who study deep ocean cores, botanists who follow the tree line as it climbs up the Andes, marine biologists who dive off the Great Barrier Reef. She introduces us to a dozen species, some already gone, others facing extinction, including the Panamian golden frog, staghorn coral, the great auk, and the Sumatran rhino. Through these stories, Kolbert provides a moving account of the disappearances occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up through the present day. The sixth extinction is likely to be mankind's most lasting legacy; as Kolbert observes, it compels us to rethink the fundamental question of what it means to be human.

Book Description
"You can't really know the place where you live until you know the shapes and origins of the land around you. To feel truly at home in the Bay Area, read Doris Sloan's intriguing stories of this region's spectacular, quirky landscapes."—Hal Gilliam, author of Weather of the San Francisco Bay Region "This is a fascinating look at some of the world's most complex and engaging geology. I highly recommend this book to anyone interested in an understanding of the beautiful landscape and dynamic geology of the Bay Area."—Mel Erskine, geological consultant "This accessible summary of San Francisco Bay Area geology is particularly timely. We are living in an age where we must deal with our impact on our environment and the impact of the environment on us. Earthquake hazards, and to a lesser extent landslide hazards, are well known, but the public also needs to be aware of other important engineering and environmental impacts and geologic resources. This book will allow Bay Area residents to make more intelligent decisions about the geological issues affecting their lives."—John Wakabayashi, geological consultant
