In this exploration of the concept of the gene, Jonathan Slack looks at the discovery, nature, and role of genes in both evolution and development. Explaining the nature of genetic variation in the human population, how hereditary factors were identified as molecules of DNA, and how certain specific mutations can lead to disease, Slack highlights how DNA variants are used to trace human ancestry and migration, and can also used by forensic scientists to identify individuals in crime. He also explores issues such as the role of genetic heritability and IQ as well as the changes that occur in the genes of populations during evolution. An ideal guide for anyone curious about what genes are and how genetics can be put to use, this Very Short Introduction demonstrates the ways in which the gene concept has been understood and used by molecular biologists, population biologists, and social scientists around the world.

Coral reefs have been long regarded with awe by the millions of people who have encountered them over the centuries. Early seafarers were wary of them, naturalists were confused by them, yet many coastal people benefited greatly from these mysterious rocky structures that grew up to the surface of the sea. They have been rich in their supply of food, and they provided a breakwater from storms and high waves to countless coastal communities that developed from their protection. Their scale is enormous and their value high. Found in countless locations around the world, from the Indo-Pacific coral reef province to the Caribbean and Australia, they support both marine and human life. In this Very Short Introduction, Charles Sheppard provides an account of what coral reefs are, how they are formed, how they have evolved, and the biological lessons we can learn from them. Today, the vibrancy and diversity of these fascinating ecosystems are under threat from over exploitation and could face future extinction, unless our conservation efforts are stepped up in order to save them.

The importance of complexity is well-captured by Hawking's comment: Complexity is the science of the 21st century. From the movement of flocks of birds to the Internet, environmental sustainability, and market regulation, the study and understanding of complex non-linear systems has become highly influential over the last 30 years. In this Very Short Introduction, one of the leading figures in the field, John Holland, introduces the key elements and conceptual framework of complexity. From complex physical systems such as fluid flow and the difficulties of predicting weather, to complex adaptive systems such as the highly diverse and interdependent ecosystems of rainforests, he combines simple, well-known examples — Adam Smith's pin factory, Darwin's comet orchid, and Simon's watchmaker — with an account of the approaches, involving agents and urn models, taken by complexity theory.

Nutrition is a topic of wide interest and importance. In spite of growing understanding of the underlying biochemistry, and health campaigns such as five-a-day, increasing obesity and reported food allergies and eating disorders, as well as the widely advertised supposed benefits of food supplements mean that a clear explanation of the basic principles of a healthy diet are vital. In this Very Short Introduction, David Bender explains the basic elements of food, the balance between energy intake and exercise, the problems of over and under-nutrition, and raises the question of safety of nutritional supplements.

Since the first African American denomination was established in Philadelphia in 1818, churches have gone beyond their role as spiritual guides in African American communities and have served as civic institutions, spaces for education, and sites for the cultivation of individuality and identities in the face of limited or non-existent freedom. In this Very Short Introduction, Eddie S. Glaude Jr. explores the history and circumstances of African American religion through three examples: conjure, African American Christianity, and African American Islam. He argues that the phrase African American religion is meaningful only insofar as it describes how through religion, African Americans have responded to oppressive conditions including slavery, Jim Crow apartheid, and the pervasive and institutionalized discrimination that exists today. This bold claim frames his interpretation of the historical record of the wide diversity of religious experiences in the African American community. He rejects the common tendency to racialize African American religious experiences as an inherent proclivity towards religiousness and instead focuses on how religious communities and experiences have developed in the African American community and the context in which these developments took place.

Africa is home to hundreds of ethnic groups, who together speak more than a thousand languages. It is not surprising, then, that Africa's enormous range of peoples, cultures, and ways of life has engendered a wide diversity of religious practices. This Very Short Introduction offers a wide-ranging look at the myriad indigenous religious traditions on the African continent. Drawing on archeological research, historical evidence, ethnographic studies, and archival materials such as missionary records, Jacob Olupona-one of the world's leading authorities on African religions-captures a wealth of information in a short compass. The book not only gives the reader a full and vivid sense of African religious belief-exploring myths, gods and local deities, ancestor worship, rites of passage, festivals, divination, and much more-but it also underscores the role these religions play in everyday African life. Indeed, traditional religions inform everything from birthing and death, marriage and family dynamics, to diet, dress and grooming, health care, and even governance. Monarchs, chiefs, and elders play both political and religious roles, imparting secular and spiritual guidance to their subjects, while also being guardians of religious centres such as shrines, temples, and sacred forests. The author also examines the spread of Christianity and Islam throughout Africa, both the moderate sects (which often blend aspects of indigenous faith into their own practice) and the more extreme fundamentalist sects, which the author states have had a dire effect on African life. In fact, radical forms of Christianity and Islam-both of which decry tradition religion as paganism-have driven a near total collapse of indigenous practice. But if traditional religions are engaged in a battle for their lives in Africa, Olupona shows that they are thriving elsewhere in the world-particularly in the Americas and in Europe.

From popular histories through to reworkings of classical subject matter by contemporary poets, dramatists, and novelists, the classical world and the masterpieces of its literature continue to fascinate readers and audiences in a huge variety of media. In this Very Short Introduction, William Allan explores what the 'classics' are and why they continue to shape our Western concepts of literature. Presenting a range of material from both Greek and Latin literature, he illustrates the variety and sophistication of these works, and considers examples from all the major genres. Ideal for the general reader interested in works of classic literature, as well as students at A-Level and University, this is a lively and lucid guide to the major authors and literary forms of the ancient period.

Ethnomusicologists believe that all humans, not just those we call musicians, are musical, and that musicality is one of the essential touchstones of the human experience. 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.

If you read the 'business pages' of a newspaper or if you listen to the financial news on the television or radio, you will often hear terms such as liability, balance sheet or earnings. These terms turn up in non-financial contexts as well: he was more of a liability than an asset. If you invest in shares, have a building society account, or sit on a committee of the property company which owns your apartment block, you will receive financial statements every year. If you are a manager in a company, a hospital or a school, you will see accounting information often. This Very Short Introduction provides a guide to understanding and using accounting information. Christopher Nobes explains the main areas of accounting work, from bookkeeping and financial reporting to auditing and management accounting.

Microeconomics — individuals' choices of where to live and work, how much to save, what to buy, and firms' decisions about location, hiring, firing, and investment — involves issues that concern us on a daily basis. But when people think about economics, they tend to place importance on the bigger picture — macroeconomics — including issues such as unemployment, inflation, and the competitiveness of nations. In this Very Short Introduction, Avinash Dixit argues that the microeconomy has a large impact on the economic world, arguably as much as the issues of macroeconomics. Dixit steers a clear path through the huge number of issues related to microeconomics, explaining what happens when things go well, as well as showing how they fail, why that happens, and what can be done about it. Using real-life examples from around the world, using the minimum of mathematics and including simple graphs, he provides insights into economics from psychology and sociology to explain economic behaviour and rational choice. An ideal introduction for anyone interested in business and economics.

Alexander the Great became king of Macedon in 336 BC, when he was only 20 years old, and died at the age of 32, twelve years later. During his reign he conquered the Achaemenid Persian Empire, the largest empire that had ever existed, leading his army from Greece to Pakistan, and from the Libyan desert to the steppes of Central Asia. His meteoric career, as leader of an alliance of Greek cities, Pharaoh of Egypt, and King of Persia, had a profound effect on the world he moved through. Even in his lifetime his achievements became legendary and in the centuries that following his story was told and retold throughout Europe and the East. Greek became the language of power in the Eastern Mediterranean and much of the Near East, as powerful Macedonian dynasts carved up Alexander's empire into kingdoms of their own, underlaying the flourishing Hellenistic civilization that emerged after his death. But what do we really know about Alexander? In this Very Short Introduction, Hugh Bowden goes behind the usual historical accounts of Alexander's life and career. Instead, he focuses on the evidence from Alexander's own time — letters from officials in Afghanistan, Babylonian diaries, records from Egyptian temples — to try and understand how Alexander appeared to those who encountered him. In doing so he also demonstrates the profound influence the legends of his life have had on our historical understanding and the controversy they continue to generate worldwide.

Europeans, Africans, and American Indians practiced slavery long before the first purchase of a captive African by a white land-owner in the American colonies; that, however, is the image of slavery most prevalent in the minds of Americans today. This Very Short Introduction begins with the Portuguese capture of Africans in the 1400s and traces the development of American slavery until its abolition following the Civil War. Historian Heather Andrea Williams draws upon the rich recent scholarship of numerous highly-regarded academics as well as an analysis of primary documents to explore the history of slavery and its effects on the American colonies and later the United States of America. Williams examines legislation that differentiated American Indians and Africans from Europeans as the ideology of white supremacy flourished and became an ingrained feature of the society. These laws reflected the contradiction of America's moral and philosophical ideology that valorized freedom on one hand and justified the enslavement of a population deemed inferior on another. She explores the tense and often violent relationships between the enslaved and the enslavers, and between abolitionists and pro-slavery advocates as those who benefited from the institution fought to maintain and exert their power. Williams is attentive to the daily labors that enslaved people performed, reminding readers that slavery was a system of forced labor with economic benefits that produced wealth for a new nation, all the while leaving an indelible mark on its history.

What is a family? What makes someone a parent? What rights should children have? Family Law: A Very Short Introduction gives the reader an insight not only into what the law is, but why it is the way it is. It examines how laws have had to respond to social changes in family life, from rapidly rising divorce rates to surrogate mothers, and gives insight into family courts which are required to deal with the chaos of family life and often struggle to keep up-to-date with the social and scientific changes which affect it. It also looks to the future: what will families look like in the years ahead? What new dilemmas will the courts face?

To understand China, it is essential to understand Confucianism. First formulated in the sixth century BCE, the teachings of Confucius would come to dominate Chinese society, politics, economics, and ethics. In this Very Short Introduction, Daniel K. Gardner explores the major philosophical ideas of the Confucian tradition, showing their profound impact on state ideology and imperial government, the civil service examination system, domestic life, and social relations over the course of twenty-six centuries. Gardner focuses on two of the Sage's most crucial philosophical problems-what makes for a good person, and what constitutes good government-and demonstrates the enduring significance of these questions today. This volume shows the influence of the Sage's teachings over the course of Chinese history-on state ideology, the civil service examination system, imperial government, the family, and social relations-and the fate of Confucianism in China in the nineteenth and twentieth centuries, as China developed alongside a modernizing West and Japan. Some Chinese intellectuals attempted to reform the Confucian tradition to address new needs; others argued for jettisoning it altogether in favor of Western ideas and technology; still others condemned it angrily, arguing that Confucius and his legacy were responsible for China's feudal, backward conditions in the twentieth century and launching campaigns to eradicate its influences. Yet Chinese continue to turn to the teachings of Confucianism for guidance in their daily lives. In addition to a survey of the philosophy and history of Confucianism, Gardner offers an examination of the resurgence of Confucianism in China today, and explores what such a revival means for the Chinese government and the Chinese people.

Humour has been discovered in every known human culture and thinkers have discussed it for over two thousand years. Humour can serve many functions; it can be used to relieve stress, to promote goodwill among strangers, to dissipate tension within a fractious group, to display intelligence, and some have even claimed that it improves health and fights sickness. In this Very Short Introduction Noel Carroll examines the leading theories of humour including The Superiority Theory and The Incongruity Theory. He considers the relation of humour to emotion and cognition, and explores the value of humour, specifically in its social functions. He argues that humour, and the comic amusement that follows it, has a crucial role to play in the construction of communities, but he also demonstrates that the social aspect of humour raises questions such as When is humour immoral? and Is laughing at immoral humour itself immoral?

What is knowledge? Is it the same as opinion or truth? Do you need to be able to justify a claim in order to count as knowing it? How can we know that the outer world is real and not a dream? Questions like these are ancient ones, and the branch of philosophy dedicated to answering them — epistemology — has been active for thousands of years. In this thought provoking Very Short Introduction, Jennifer Nagel considers the central problems and paradoxes in the theory of knowledge whilst drawing attention to the ways in which philosophers and theorists have responded to them. By exploring the relationship between knowledge and truth, and considering the problem of scepticism, Nagel introduces a series of influential historical and contemporary theories of knowledge, incorporating methods from logic, linguistics, and psychology, and using a number of everyday examples to demonstrate the key issues and debates.
