There are nearly 6,000 mammalian species, among them our own. Research on our evolutionary cousins has a long history, but the last 20 years have seen particularly rapid progress in disentangling the interrelationships and evolutionary history of mammals. The present volume combines up-to-date reviews on mammalian phylogenetics with paleontological, taxonomic and evolutionary chapters and also summarizes the historical development of our insights in mammalian relationships, and thus our own place in the Tree of Life. Our book places the present biodiversity crisis in context, with one in four mammal species threatened by extinction, and reviews the distribution and conservation of mammalian diversity across the globe. This volume is the introductory tome to the new Mammalia series of the Handbook of Zoology and will be essential reading for mammalogists, zoologists and conservationists alike.

Jesus Loves You and Evolution Is True

Science is not a danger to the faith of Christian youth. In fact, Sara Sybesma Tolsma, an award-winning scientist, and Jason Lief, a leading practical theologian, argue that youth ministry needs science to help young people explore their relationship to God and engage their world faithfully. Jesus Loves You and Evolution Is True invites the church and its leaders to open their minds and hearts to what science can tell us about our human lives and our connections to, and role in, our natural world. But it does not stop there: evolutionary science is theological, argues Lief and Tolsma, and so it must have a central place in the day-to-day work of youth ministry. If the church wants to help youth develop robust spiritual lives and prepare them for the challenges that life will bring them, pastors, faith leaders, and youth workers must not only engage science but embrace its lessons for the life and practice of Christian faith today.

A small set of fossilized bones discovered almost thirty years ago led paleontologist Sankar Chatterjee on a lifelong quest to understand their place in our understanding of the history of life. They were clearly the bones of something unusual, a bird-like creature that lived long, long ago in the age of dinosaurs. He called it Protoavis, and the animal that owned these bones quickly became a contender for the title of "oldest known bird." In 1997, Chatterjee published his findings in the first edition of The Rise of Birds. Since then Chatterjee and his colleagues have searched the world for more transitional bird fossils. And they have found them. This second edition of The Rise of Birds brings together a treasure trove of fossils that tell us far more about the evolution of birds than we once dreamed possible. With no blind allegiance to what he once thought he knew, Chatterjee devours the new evidence and lays out the most compelling version of the birth and evolution of the avian form ever attempted. He takes us from Texas to Spain, China, Mongolia, Madagascar, Australia, Antarctica, and Argentina. He shows how, in the "Cretaceous Pompeii" of China, he was able to reconstruct the origin and evolution of flight of early birds from the feathered dinosaurs that lay among thousands of other amazing fossils. Chatterjee takes us to where long-hidden bird fossils dwell. His compelling, occasionally controversial, revelations—accompanied by spectacular illustrations—are a must-read for anyone with a serious interest in the evolution of "the feathered dinosaurs," from vertebrate paleontologists and ornithologists to naturalists and birders. -- Alan Feduccia, University of North Carolina

This comprehensive text is a major synthesis on ecological change in the Gulf of Alaska. It encompasses the structural and annual changes, forces of change, long-ecological changes in the atmosphere and ocean, plankton, fish, birds and mammals, and the effects of the 1989 Exxon Valdez Oil Spill. With 5 major sections, Long-term Ecological Change in the Northern Gulf of Alaska first describes the physical features, the atmosphere and physical oceanography, the annual production cycle, the forage base for higher animals and trophic transfer, and the adaptations for survival in this changing environment for 9 portal species. Then, the major forces of change are introduced: climate, geophysics, fisheries and harvesting, species interactions, disease and contaminants. Next, the long-term records of change in physical factors and biological populations are presented, as well as the potential reasons for the biological changes. Following is the history of the Exxon Valdez oil spill and its long-term effects. And, finally, the emergent properties of the ecosystem are discussed and an attempt is made to weigh the importance of the major forcing factors in terms of their temporal and spatial scales of influence. * Examines important data on long-term change in the ecosystem and the forcing factors that are responsible for it * Provides an account of the 1989 Exxon Valdez oil spill with emphasis on the long-term effects * Describes the effects of climate change, geophysical change, species interactions, harvesting, disease, the 1989 oil spill, and marine contaminants on key populations of marine organisms

The central goal of the In the Light of Evolution (ILE) series is to promote the evolutionary sciences through state-of-the-art colloquia--in the series of Arthur M. Sackler colloquia sponsored by the National Academy of Sciences--and their published proceedings. Each installment explores evolutionary perspectives on a particular biological topic that is scientifically intriguing but also has special relevance to contemporary societal issues or challenges. This book is the outgrowth of the Arthur M. Sackler Colloquium "Brain and Behavior," which was sponsored by the National Academy of Sciences on January 20-21, 2012, at the Academy's Arnold and Mabel Beckman Center in Irvine, CA. It is the sixth in a series of Colloquia under the general title "In the Light of Evolution." Specifically, In Light of Evolution: Brain and Behavior focuses on the field of evolutionary neuroscience that now includes a vast array of different approaches, data types, and species. This volume is also available for purchase with the In the Light of Evolution six-volume set.
