This Very Short Introduction presents a succinct guide to the key episodes in that story - from the very origins of life four million years ago to the extraordinary diversity of species around the globe today.Beginning with an explanation of the controversies surrounding the birth of life itself, each following chapter tells of a major breakthrough that made new forms of life possible: including sex and multicellularity, hard skeletons, and the move to land. Along the way, we witness the greatest mass extinction, the first forests, the rise of modern ecosystems, and, most recently, conscious humans.Introducing ideas from a range of scientific disciplines, from evolutionary biology and earth history, to geochemistry, palaeontology, and systematics, Michael Benton explains how modern science pieces the evidence in this vast evolutionary puzzle together, to build up an accessible and up-to-date picture of the key developments in the history of life on earth.

    A criminal case can often hinge on a piece of evidence such as a hair, a blood trace, a bit of saliva on a cigarette butt, or the telltale mark of a tire tread. High profile cases have stoked this interest in recent years and some of the most popular shows on television--such as CSI: Crime Scene Investigation and its raft of spin-offs--attest to the enduring popularity of forensic science as a form of grisly entertainment. This Very Short Introduction looks at the nature of forensic science, examining what forensic science is, how it is used in the investigation of crime, how crime scenes are managed, how forensic scientists work, the different techniques used to recover evidence, and the range of methods available for analysis. It also considers how forensic science serves the criminal justice system and the challenges of communicating complex scientific evidence in a court of law.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundreds of key topics, from philosophy to Freud, quantum theory to Islam.

    Yet media interest and extensive coverage has tended to hinder rather than help our understanding of Iran as an idea, an identity, and a people, leading to a superficial understanding of what is a complex and nuanced political culture and civilization. This Very Short Introduction presents a radical reinterpretation of Iranian history and politics, placing the Islamic Revolution in the context of a century of political change and social transformation. By considering the various factors that have contributed towards the construction of the idea of Iran and the complex identity of Iranians themselves, Ali Ansari steers a clear path towards a more realistic understanding for us all.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    This book describes what schizophrenia is really like, how the illness progresses, and the treatments that have been applied. It also summarizes the most up-to-date knowledge available about the biological bases of this disorder. Finally it attempts to give some idea of what it is like to have schizophrenia and what this disorder tells us about the relationship between mind and brain.

    Readers meet a people highly skilled in sculpture, astronomy, city planning, poetry, and philosophy, who were also profoundly committed tocosmic regeneration through the thrust of the ceremonial knife and through warfare. Dav�d Carrasco looks beyond Spanish accounts that have colored much of the Western narrative to let Aztec voices speak about their origin stories, the cosmic significance of their capital city, their methods of childrearing, and the contributions women made to daily life and the empire. Carrasco discusses the arrival of the Spaniards, contrasts Aztec mythical traditions about the origins of their city with actual urban life in Mesoamerica, and outlines the rise of the Aztec empire. He also explores Aztecreligion, which provided both justification for and alternatives to warfare, sacrifice, and imperialism, and he sheds light on Aztec poetry, philosophy, painting, and especially monumental sculpture and architecture. He concludes by looking at how the Aztecs have been portrayed in Western thought, art, film, and literature as well as in Latino culture and arts.

    In The Blues, Wald surveys a genre at the heart of American culture.It is not an easy thing to pin down. As Howlin' Wolf once described it, "When you ain't got no money and can't pay your house rent and can't buy you no food, you've damn sure got the blues." It has been defined by lyrical structure, or as a progression of chords, or as a set of practices reflecting West African "tonal and rhythmic approaches," using a five-note "blues scale." Wald sees blues less as a style than as a broad musical tradition within a constantly evolving pop culture. He traces its roots in work and praise songs, and shows how it was transformed by such professional performers as W. C. Handy, who first popularized the blues a century ago. He follows its evolution from Ma Rainey and Bessie Smith through Bob Dylan and Jimi Hendrix; identifies the impact of rural field recordings of Blind Lemon Jefferson, Charley Patton and others; explores the role of blues in the development of both country music and jazz; and looks at the popular rhythm and blues trends of the 1940s and 1950s, from the uptown West Coast style of T-Bone Walker to the "down home" Chicago sound of Muddy Waters. Wald brings the story up to the present, touching on the effects of blues on American poetry, and its connection to modern styles such as rap.As with all of Oxford's Very Short Introductions, The Blues tells you--with insight, clarity, and wit--everything you need to know to understand this quintessentially American musical genre.

    It avoids the traditional style-spotting approach and instead gives us an idea of what it is about buildings that moves us, and what it is that makes them important artistically and culturally. The book begins by looking at how architecture acquires meaning through tradition, and concludes with the exoticism of the recent avant-garde period. Illustrations of particular buildings help to anchor the general points with specific examples, from ancient Egypt to the present day.

    Scerri looks at the trends in properties of elements that led to the construction of the periodic table, and how the deeper meaning of its structure gradually became apparent with the development of atomic theory and quantum mechanics, so that physics arguably came to colonize an entirely different science, chemistry.

    Moreover, groundbreaking research on genes, and especially key families of genes such as the Homeobox genes which controlthe development of body plans, has led to radical changes in the classification of animals. In this Very Short Introduction, Peter Holland presents a cutting-edge tour of the animal kingdom, providing an authoritative summary of the modern view of animal life, its origins, and the new classificationresulting from DNA studies. Beginning with the definition of animals (not obvious in biological terms), Holland takes the reader through the revolutionary new high-level groupings of animals (phyla) based on evolutionary relationships and ancestry. Ranging from corals and sponges to nematodes, seasquirts, and vertebrates, and illuminating many key topics in zoology, this fascinating, brief overview will be of great value to all students of the life sciences as well as providing a concise summary for the interested lay reader.

    However, their impact has not been limited to debates about geology and evolution: attempts to explain their existence has shaken religion at its very roots, and they have remained a subject of ceaseless fascination for people of all ages and backgrounds. In this readable and wide-ranging book, Keith Thomson provides a remarkably all-encompassing explanation of fossils as a phenomenon. How did Darwin use fossils to support his theory of evolution? What are living fossils? What fossils will we leave behind for future generations to examine? Beyond the scientific aspects, Thomson highlights the impact of fossils on philosophy and mythology, our concept of time, and today's popular culture. From the black market to the Piltdown Man, and from mythological dragons to living dinosaurs, fossils hold a permanent place in the popular imagination.

    It is truly a vital field, central to the health of society, but it is often poorly understood, largely due to misrepresentations in the media. In this Very Short Introduction, an internationally recognized authority on epidemiology, Dr. Rodolfo Saracci, provides a wealth of information on this key field, dispelling some of the myths surrounding the study of epidemiology, and explaining what epidemiology is and how vital it is to the discovery, control, and prevention of disease in world populations. Dr. Saracci provides a general explanation of the principles behind clinical trials, and explains the nature of basic statistics concerning disease. He also looks at the ethical and political issues related to obtaining and using information concerning patients, and trials involving placebos.

    The growing number of patients being diagnosed with depression, ADD, alcoholism, and other illnesses mean that few people are not touched by it. This book provides a valuable and comprehensible introduction to the subject. It starts with the history of its development as a scientific field, including the identification of major mental illnesses, the rise and fall of the asylum system, and the flourishing of psychoanalysis and other psychotherapies. More than any other branch of medicine, psychiatry has been attacked and criticized. There is a long list of perceived horrors--patient abuse, bizarre medical experiments, mind-control by evil governments, coercion by maniacal hypnotists. Modern psychiatry brings with it new controversies, such as the perceived over-prescription of antidepressants and behavior modifiers for children and teens, or unchecked marketing power of drug companies. This book does not draw conclusions on these issues, but rather provides the reader with a clear understanding of what psychiatry is, and what it does, so that they can draw their own. It is a great reference for anyone with an interest in mental illness and its treatment, students of psychiatry, medicine, psychology, and history of science, and health professionals.

    But how did they come to be here? What were their agricultural, spiritual, and hunting practices? How did their societies evolve and what challenges do they face today? Eminent historians Theda Perdue and Michael Green begin by describing how nomadic bands of hunter-gatherers followed the bison and woolly mammoth over the Bering land mass between Asia and what is now Alaska between 25,000 and 15,000 years ago, settling throughout North America. They describehunting practices among different tribes, how some made the gradual transition to more settled, agricultural ways of life, the role of kinship and cooperation in Native societies, their varied burial rites and spiritual practices, and many other features of Native American life. Throughout the book, Perdue and Green stress the great diversity of indigenous peoples in America, who spoke more than 400 different languages before the arrival of Europeans and whose ways of life varied according to the environments they settled in and adapted to so successfully. Most importantly, the authors stresshow Native Americans have struggled to maintain their sovereignty--first with European powers and then with the United States--in order to retain their lands, govern themselves, support their people, and pursue practices that have made their lives meaningful. Going beyond the stereotypes that so often distort our views of Native Americans, this Very Short Introduction offers a historically accurate, deeply engaging, and often inspiring account of the wide array of Native peoples in America.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.
