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.

    It tackles many questions, such as: What accounts for the perpetuation of ethnic and religious conflict in Ireland? Why has armedviolence proven so hard to control? Who are the major figures and issues in the conflict? Can we expect more Northern Irelands in the future?

    But when did this essential part of our lives begin? Why do we all write differently and how did writing evolve into what we use today? All of these questions are answered in this Very Short Introduction. Andrew Robinson tells the fascinating story of the history of writing, shedding light on its development and examining the enormous variety of writing and scripts we use today. Starting with the origins of writing five thousand years ago, with cuneiform and Egyptian hieroglyphs, Robinson explains how these early forms developed into hundreds of scripts, including the Roman alphabet and Chinese characters. He reveals how the modern writing symbols and abbreviations we take for granted today--including airport signage and text messaging--resemble ancient ones much more closely than we might think. The book also includes a chronology of events from 3300 BC to AD 2000, a list of titles for further reading, and an index.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    From randomized clinical trials in medical research, to statistical models of risk in banking and hedge fund industries, to the statistical tools used to probe vast astronomical databases, the field of statistics has become centrally important to how we understand our world. But the discipline underlying all these is not the dull statistics of the popular imagination. Long gone are the days of manual arithmetic manipulation. Nowadays statistics is a dynamic discipline, revolutionized by the computer, which uses advanced software tools to probe numerical data, seeking structures, patterns, and relationships. This Very Short Introduction sets the study of statistics in context, describing its history and giving examples of its impact, summarizes methods of gathering and evaluating data, and explains the role played by the science of chance, of probability, in statistical methods. The book also explores deep philosophical issues of induction--how we use statistics to discern the true nature of reality from the limited observations we necessarily must make.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    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.

    The term has become something of a catch-all, a convenient way to encompass numerous issues and developments which pertain to the political, social, and economic history of modern Ireland. It is a question which refuses to go away, but it is also a question whose inconstant meaning is rarely anatomized and still less often denied. One of the main aims of this book is to explore the complicated and shifting nature of the Irish Question, and to assess what it has meant to various political minds and agendas. The book is arranged both thematically and chronologically; each of the eight chapters takes as its focus a particular period, and each period is discussed within the context of one or more questions which informed and shaped that particular period.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    He examines the ethical responsibility of the journalist to respond to the demands of civil society, as opposed to the demands of the state, and focuses on contentious issues in contemporary journalism, such as intrusion, lack of accountability, obscenity, trivialization, rumor-mongering, and libel.

    They are the oldest forms of life and the most prolific of all living organisms, inhabiting every part of the Earth's surface, its ocean depths, and even such inhospitable places as boiling hot springs. In this Very Short Introduction, bacteriologist Sebastian Amyes explores the nature of bacteria, their origin and evolution, bacteria in the environment, and bacteria and disease. Amyes discusses some of the major infections caused by bacteria-bacteria causes pneumonia, diphtheria, cholera, and many other diseases-and shows how these pathogens avoid the defences of the human body. But the book looks at all aspects of bacteria, not just the negative side, stressing the key benefits of bacteria, which have been harnessed to preserve food, dispose of waste and to provide compost for horticulture. Indeed, life for man and for many animals would be impossible without bacteria. Amyes also offers a glance into the future, describing how bacteria might be manipulated to perform tasks that they previous were unable to perform and discussing the recent construction of a completely synthetic bacterial cell.

    While pure mathematics is mostly interested in abstract structures, applied mathematics sits at the interface between this abstract world and the world inwhich we live. This area of mathematics takes its nourishment from society and science and, in turn, provides a unified way to understand problems arising in diverse fields.This Very Short Introduction presents a compact yet comprehensive view of the field of applied mathematics, and explores its relationships with (pure) mathematics, science, and engineering. Explaining the nature of applied mathematics, Alain Goriely discusses its early achievements in physics andengineering, and its development as a separate field after World War II. Using historical examples, current applications, and challenges, Goriely illustrates the particular role that mathematics plays in the modern sciences today and its far-reaching potential.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    In this Very Short Introduction, leading authority Jonathan Slack offers a clear and informative overview of stem cells--what they are, what scientists do with them, what stem cell therapies are available today, and how they might be used in the future. Slack explains the difference between embryonic stem cells, which exist only in laboratory cultures, and tissue-specific stem cells, which exist in our bodies, and he discusses how embryonic stem cells may be used in the future to treat such illnesses as diabetes, Parkinson's disease, heart disease, spinal trauma, and retinal degeneration. But he stresses that, despite important advances, the clinical applications of stem cells are still in their infancy and that most real stem cell therapy today is some form of bone marrow transplantation. Slack concludes by analyzing how medical innovation has occurred in this area in recent years and he draws out some of the lessons for the development of new therapies in the future.

    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.

    Plants have also become essential to humans not only in the form of cereal crops, fruit, and vegetables, but in their many other uses in wood and paper, and in providing medicines. In this Very Short Introduction Timothy Walker, Director of the Botanical Gardens in Oxford, provides a concise account of the nature of plants, their variety and classification, their evolution, and their aesthetic and practical value, stressing the need for their conservation for future generations.

    This insight raises big questions about the nature of music and the nature of humankind, and ethnomusicologists argue that to properly address these questions, we must study music in all its geographical and historical diversity.In this Very Short Introduction, one of the foremost ethnomusicologists, Timothy Rice, offers a compact and illuminating account of this growing discipline, showing how modern researchers go about studying music from around the world, looking for insights into both music and humanity. The reader discovers that ethnomusicologists today not only examine traditional forms of music-such as Japanese gagaku, Bulgarian folk music, Javanese gamelan, or Native American drumming and singing-but also explore more contemporary musical forms, from rap and reggae to Tex-Mex, Serbian turbofolk, and even the piped-in music at the Mall of America. To investigate these diverse musical forms, Rice shows, ethnomusicologists typically live in a community, participate in and observe and record musical events, interview the musicians, their patrons, and the audience, and learn to sing, play, and dance. It's important to establish rapport with musicians and community members, and obtain the permission of those they will work with closely over the course of many months and years. We see how the researcher analyzes the data to understand how a particular musical tradition works, what is distinctive about it, and how it bears the personal, social, and cultural meanings attributed to it. Rice also discusses how researchers may apply theories from anthropology and other social sciences, to shed further light on the nature of music as a human behavior and cultural practice.About the Series: Oxford's Very Short Introductions series offers concise and original introductions to a wide range of subjects--from Islam to Sociology, Politics to Classics, Literary Theory to History, and Archaeology to the Bible.
