One of the most controversial episodes in the life of the Prophet Muhammad concerns an incident in which he allegedly mistook words suggested by Satan as divine revelation. Known as the Satanic verses, these praises to the pagan deities contradict the Islamic belief that Allah is one and absolute. Muslims today—of all sects—deny that the incident of the Satanic verses took place. But as Shahab Ahmed explains, Muslims did not always hold this view.

Before Orthodoxy wrestles with the question of how religions establish truth—especially religions such as Islam that lack a centralized authority to codify beliefs. Taking the now universally rejected incident of the Satanic verses as a case study in the formation of Islamic orthodoxy, Ahmed shows that early Muslims, circa 632 to 800 CE, held the exact opposite belief. For them, the Satanic verses were an established fact in the history of the Prophet. Ahmed offers a detailed account of the attitudes of Muslims to the Satanic verses in the first two centuries of Islam and traces the chains of transmission in the historical reports known as riwāyah.

Touching directly on the nature of Muhammad’s prophetic visions, the interpretation of the Satanic verses incident is a question of profound importance in Islam, one that plays a role in defining the limits of what Muslims may legitimately say and do—issues crucial to understanding the contemporary Islamic world.

Contemporaries of Carroll D. Wright (1840-1909) lived through the transformation of American society by the industrial revolution. For the most part they thought the transformation represented growth and progress, but many also found occasion for doubt and fear in its consequences. Their anxieties collected around the notions of a "labor problem" and "labor reform." Whether from hope or fear, people felt a need for statistical information. On this popular demand Wright built his career as statistical expert and renowned master of "labor statistics." His investigations during thirty-two years of government service (1873-1905) gave form to contemporary ideas and set precedents for modern procedures, as in his seminal studies of wages, prices, and strikes.

In telling how Wright took up this unprecedented career, Mr. Leiby shows the importance of Wright's early years and relates his work to the politics and religion of his time as well as to its social science. In this perspective, the history of the labor bureaus and their voluminous reports take on their original human purposes and meaning.

We are connected to distant space and time not only by our imaginations but also through a common cosmic heritage. Emerging now from modern science is a unified scenario of the cosmos, including ourselves as sentient beings, based on the time-honored concept of change. From galaxies to snowflakes, from stars and planets to life itself, we are beginning to identify an underlying ubiquitous pattern penetrating the fabric of all the natural sciences--a sweepingly encompassing view of the order and structure of every known class of object in our richly endowed universe.

This is the subject of Eric Chaisson's new book. In Cosmic Evolution Chaisson addresses some of the most basic issues we can contemplate: the origin of matter and the origin of life, and the ways matter, life, and radiation interact and change with time. Guided by notions of beauty and symmetry, by the search for simplicity and elegance, by the ambition to explain the widest range of phenomena with the fewest possible principles, Chaisson designs for us an expansive yet intricate model depicting the origin and evolution of all material structures. He shows us that neither new science nor appeals to nonscience are needed to understand the impressive hierarchy of the cosmic evolutionary story, from quark to quasar, from microbe to mind.

Ordinary people of antiquity interacted with the supernatural through a mosaic of beliefs and rituals. Exploring everyday life from 200 BCE to the end of the first century CE, Robert Knapp shows that Jews and polytheists lived with the gods in very similar ways. Traditional interactions provided stability even in times of crisis, while changing a relationship risked catastrophe for the individual, his family, and his community. However, people in both traditions did at times leave behind their long-honored rites to try something new. The Dawn of Christianity reveals why some people in Judea and then in the Roman and Greek worlds embraced a new approach to the forces and powers in their daily lives.

Knapp traces the emergence of Christianity from its stirrings in the eastern Mediterranean, where Jewish monotheism coexisted with polytheism and prayer mixed with magic. In a time receptive to prophetic messages and supernatural interventions, Jesus of Nazareth convinced people to change their beliefs by showing, through miracles, his direct connection to god-like power. The miracle of the Resurrection solidified Jesus’s supernatural credentials. After his death, followers continued to use miracles and magic to spread Jesus’s message of reward for the righteous in this life and immortality in the next.

Many Jews and polytheists strongly opposed the budding movement but despite major setbacks Christianity proved resilient and adaptable. It survived long enough to be saved by a second miracle, the conversion of Emperor Constantine. Hand in hand with empire, Christianity began its long march through history.

Features:

• Paperback format of an essential Brill resource
• Essays that combine cognitive analysis with historical and social-scientific approaches to biblical materials, Christian origins, and early Judaism
• Research for historians of religion, biblical scholars, and those working in the cognitive science of religion.

During the Middle Paleolithic, various populations ancestral to modern Homo sapiens inhabited Africa, while Europe was homeland to the Neandertals. Recent archaeological investigations have provided data showing that the abrupt transition from the Middle to the Upper Neolithic, during which these populations met and interacted, was a fast-moving period of change for both groups.

In this volume, the expansion of modern humans and their impact on the populations of Neandertals in Europe, Western Asia, and Northern Africa is discussed in depth, with particular focus on the lithic industries of the late Middle and early Upper Paleolithic.

A Times Higher Education Book of the Week

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe—descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished. Ever since the first Neanderthal bones were identified in 1856, scientists have been vexed by the question, why did modern humans survive while their closest known relatives went extinct?

“Shipman admits that scientists have yet to find genetic evidence that would prove her theory. Time will tell if she’s right. For now, read this book for an engagingly comprehensive overview of the rapidly evolving understanding of our own origins.”
—Toby Lester, Wall Street Journal

“Are humans the ultimate invasive species? So contends anthropologist Pat Shipman—and Neanderthals, she opines, were among our first victims. The relationship between Homo sapiens and Homo neanderthalensis is laid out cleanly, along with genetic and other evidence. Shipman posits provocatively that the deciding factor in the triumph of our ancestors was the domestication of wolves.”

Islam is the fastest-growing religion in the world today. An understanding of its beliefs and practices has become essential knowledge not only for religious and political leaders but also for ordinary citizens who increasingly interact with Muslims as neighbors, coworkers, and schoolmates.

This book is designed to offer the general public a concise overview of the origins, basic beliefs, and common practices of Islam, as well as the reasons for its dramatic resurgence in recent times. Emory Bogle details the life mission of the prophet Muhammad and describes the spread of Islam after his death. He accounts for the rise and contemporary influence of Shi'i Islam, a topic of particular interest to Western readers. Bogle also explains the basic beliefs ("The Five Pillars") of Islam, as well as the role played by the Qur'an (Islam's scriptures), the hadith (the words and behavior of Muhammad), and the shari'a (Islamic law).

Since Darwin, people have speculated about the evolutionary relationships among dissimilar species, including our connections to the diverse life forms known as microbes. In the 1970s biologists discovered a way to establish these kinships. This new era of exploration began with Linus Pauling’s finding that every protein in every cell contains a huge reservoir of evolutionary history. His discovery opened a research path that has changed the way biologists and others think about the living world. In Kin John L. Ingraham tells the story of these remarkable breakthroughs. His original, accessible history explains how we came to understand our microbe inheritance and the relatedness of all organisms on Earth.

Among the most revolutionary scientific achievements was Carl Woese’s discovery that a large group of organisms previously lumped together with bacteria were in fact a totally distinct form of life, now called the archaea. But the crowning accomplishment has been to construct the Tree of Life—an evolutionary project Darwin dreamed about over a century ago. Today, we know that the Tree’s three main stems are dominated by microbes. The nonmicrobes—plants and animals, including humans—constitute only a small upper branch in one stem.

Knowing the Tree’s structure has given biologists the ability to characterize the complex array of microbial populations that live in us and on us, and investigate how they contribute to health and disease. This knowledge also moves us closer to answering the tantalizing question of how the Tree of Life began, over 3.5 billion years ago.

A rigorous and scientific analysis of the myriad possibilities of life beyond our planet.

“Are we alone in the universe?” This tantalizing question has captivated humanity over millennia, but seldom has it been approached rigorously. Today the search for signatures of extraterrestrial life and intelligence has become a rapidly advancing scientific endeavor. Missions to Mars, Europa, and Titan seek evidence of life. Laboratory experiments have made great strides in creating synthetic life, deepening our understanding of conditions that give rise to living entities. And on the horizon are sophisticated telescopes to detect and characterize exoplanets most likely to harbor life.

Life in the Cosmos offers a thorough overview of the burgeoning field of astrobiology, including the salient methods and paradigms involved in the search for extraterrestrial life and intelligence. Manasvi Lingam and Avi Loeb tackle three areas of interest in hunting for life “out there”: first, the pathways by which life originates and evolves; second, planetary and stellar factors that affect the habitability of worlds, with an eye on the biomarkers that may reveal the presence of microbial life; and finally, the detection of technological signals that could be indicative of intelligence. Drawing on empirical data from observations and experiments, as well as the latest theoretical and computational developments, the authors make a compelling scientific case for the search for life beyond what we can currently see.

Meticulous and comprehensive, Life in the Cosmos is a master class from top researchers in astrobiology, suggesting that the answer to our age-old question is closer than ever before.

All humans share three origins: the beginning of our individual lives, the appearance of life on Earth, and the formation of our planetary home. Life through Time and Space brings together the latest discoveries in both biology and astronomy to examine our deepest questions about where we came from, where we are going, and whether we are alone in the cosmos.

A distinctive voice in the growing field of astrobiology, Wallace Arthur combines embryological, evolutionary, and cosmological perspectives to tell the story of life on Earth and its potential to exist elsewhere in the universe. He guides us on a journey through the myriad events that started with the big bang and led to the universe we inhabit today. Along the way, readers learn about the evolution of life from a primordial soup of organic molecules to complex plants and animals, about Earth’s geological transformation from barren rock to diverse ecosystems, and about human development from embryo to infant to adult. Arthur looks closely at the history of mass extinctions and the prospects for humanity’s future on our precious planet.

Do intelligent aliens exist on a distant planet in the Milky Way, sharing the three origins that characterize all life on Earth? In addressing this question, Life through Time and Space tackles the many riddles of our place and fate in the universe that have intrigued human beings since they first gazed in wonder at the nighttime sky.

Even after 150 years, Darwin’s theory of evolution by natural selection is irresistibly compelling. But how can this idea—in which competition prevails—be consistent with all that we know about the thoroughly cooperative nature of life at the genetic and cellular level? This book reconciles these discrepancies.

Assembling a set of general principles, authors Kenneth Weiss and Anne Buchanan build a comprehensive, unified theory that applies on the evolutionary time scale but also on the developmental and ecological scales where daily life is lived, and cells, organisms, and species interact. They present this story through a diversity of examples spanning the fundamental challenges that organisms have faced throughout the history of life. This shows that even very complex traits can be constructed simply, based on these principles. Although relentless competitive natural selection is widely assumed to be the primary mover of evolutionary change, The Mermaid’s Tale shows how life more generally works on the basis of cooperation. The book reveals that the focus on competition and cooperation is largely an artifact of the compression of time—a distortion that dissolves when the nature and origins of adapted life are viewed primarily from developmental and evolutionary time scales.

The origins of Islam have been the subject of increasing controversy in recent years. The traditional view, which presents Islam as a self-consciously distinct religion tied to the life and revelations of the prophet Muhammad in western Arabia, has since the 1970s been challenged by historians engaged in critical study of the Muslim sources.

In Muhammad and the Believers, the eminent historian Fred Donner offers a lucid and original vision of how Islam first evolved. He argues that the origins of Islam lie in what we may call the "Believers' movement" begun by the prophet Muhammad—a movement of religious reform emphasizing strict monotheism and righteous behavior in conformity with God's revealed law. The Believers' movement thus included righteous Christians and Jews in its early years, because like the Qur'anic Believers, Christians and Jews were monotheists and agreed to live righteously in obedience to their revealed law. The conviction that Muslims constituted a separate religious community, utterly distinct from Christians and Jews, emerged a century later, when the leaders of the Believers' movement decided that only those who saw the Qur'an as the final revelation of the One God and Muhammad as the final prophet, qualified as Believers. This separated them decisively from monotheists who adhered to the Gospels or Torah.

It is now generally recognized that the publication of Darwin's Origin of Species in 1859 not only decisively altered the basic concepts of biological theory but had a profound and lasting influence on social, philosophic, and religious thought. This work is rightly regarded as one of the most important books ever printed.

The first edition had a freshness and uncompromising directness that were considerably weakened in subsequent editions. Nearly all reprints were based on the greatly modified sixth edition (1872), and the only modern reprint changes pagination, making references to the original very difficult. Clearly, there has been a need for a facsimile reprint. Professor Mayr's introduction has a threefold purpose: to list passages in the first edition that Darwin altered in later editions; to point out instances in which Darwin was clearly pioneering; and to call attention to neglected passages that show Darwin as a much deeper thinker than has been recognized. No one can fail to be impressed by the originality of Darwin's treatment and by the intellectual challenge his work presents even to the modern reader.

A century and a half after the publication of Origin of Species, evolutionary thinking has expanded beyond the field of biology to include virtually all human-related subjects—anthropology, archeology, psychology, economics, religion, morality, politics, culture, and art. Now a distinguished scholar offers the first comprehensive account of the evolutionary origins of art and storytelling. Brian Boyd explains why we tell stories, how our minds are shaped to understand them, and what difference an evolutionary understanding of human nature makes to stories we love.

Art is a specifically human adaptation, Boyd argues. It offers tangible advantages for human survival, and it derives from play, itself an adaptation widespread among more intelligent animals. More particularly, our fondness for storytelling has sharpened social cognition, encouraged cooperation, and fostered creativity.

After considering art as adaptation, Boyd examines Homer’s Odyssey and Dr. Seuss’s Horton Hears a Who! demonstrating how an evolutionary lens can offer new understanding and appreciation of specific works. What triggers our emotional engagement with these works? What patterns facilitate our responses? The need to hold an audience’s attention, Boyd underscores, is the fundamental problem facing all storytellers. Enduring artists arrive at solutions that appeal to cognitive universals: an insight out of step with contemporary criticism, which obscures both the individual and universal. Published for the bicentenary of Darwin’s birth and the 150th anniversary of the publication of Origin of Species, Boyd’s study embraces a Darwinian view of human nature and art, and offers a credo for a new humanism.

Beginning with the Roman army’s first foray beyond its borders and concluding with the death of Hadrian in 138 CE, this panoramic history of the early Roman Empire recounts the wars, leaders, and social transformations that lay the foundations of imperial success.

Between 264 BCE, when the Roman army crossed into Sicily, and the death of Hadrian nearly three hundred years later, Rome became one of the most successful multicultural empires in history. In this vivid guide to a fascinating period, David Potter explores the transformations that occurred along the way, as Rome went from republic to mercenary state to bureaucratic empire, from that initial step across the Straits of Messina to the peak of territorial expansion.

Rome was shaped by endless political and diplomatic jockeying. As other Italian city-states relinquished sovereignty in exchange for an ironclad guarantee of protection, Rome did not simply dominate its potential rivals—it absorbed them by selectively offering citizenship and constructing a tiered membership scheme that allowed Roman citizens to maintain political control without excluding noncitizens from the state’s success. Potter attributes the empire’s ethnic harmony to its relative openness.

This imperial policy adapted and persisted over centuries of internal discord. The fall of the republican aristocracy led to the growth of mercenary armies and to the creation of a privatized and militarized state that reached full expression under Julius Caesar. Subsequently, Augustus built a mighty bureaucracy, which went on to manage an empire ruled by a series of inattentive, intemperate, and bullying chief executives. As contemporary parallels become hard to ignore, The Origin of Empire makes clear that the Romans still have much to teach us about power, governance, and leadership.

America’s foremost novelist reflects on the themes that preoccupy her work and increasingly dominate national and world politics: race, fear, borders, the mass movement of peoples, the desire for belonging. What is race and why does it matter? What motivates the human tendency to construct Others? Why does the presence of Others make us so afraid?

Drawing on her Norton Lectures, Toni Morrison takes up these and other vital questions bearing on identity in The Origin of Others. In her search for answers, the novelist considers her own memories as well as history, politics, and especially literature. Harriet Beecher Stowe, Ernest Hemingway, William Faulkner, Flannery O’Connor, and Camara Laye are among the authors she examines. Readers of Morrison’s fiction will welcome her discussions of some of her most celebrated books—Beloved, Paradise, and A Mercy.

If we learn racism by example, then literature plays an important part in the history of race in America, both negatively and positively. Morrison writes about nineteenth-century literary efforts to romance slavery, contrasting them with the scientific racism of Samuel Cartwright and the banal diaries of the plantation overseer and slaveholder Thomas Thistlewood. She looks at configurations of blackness, notions of racial purity, and the ways in which literature employs skin color to reveal character or drive narrative. Expanding the scope of her concern, she also addresses globalization and the mass movement of peoples in this century. National Book Award winner Ta-Nehisi Coates provides a foreword to Morrison’s most personal work of nonfiction to date.

From Scouts to Balloon-busters, the Emergence of Air-to-Air Combat in World War I
When World War I began in August 1914, the airplane had already proven its worth as an intelligence gathering “eye-in-the-sky.” These scouting aircraft soon became indispensable to armies on both sides, and the attempt to drive enemy planes away began in earnest. Local air superiority was incorporated into battlefield strategy, and the use of aircraft to conduct offensive operations would change warfare as dramatically as the first firearms 300 years before. By the end of 1915, the basic formula of the armed scout settled on a single-seater with a machine gun synchronized to fire through its propeller blades. This heavily armed aircraft became the first true fighter plane whose primary function was to destroy enemy aircraft, whether scouts, balloons, bombers, or other fighters. A new glamorized “knight of the air” was born: the ace, a fighter pilot who brought down five or more opponents. From 1916 on, as the combatants relied on airplanes more, flying tactics and strategy—including mass formations—were developed for what would become a deadly struggle for complete air superiority. By 1918, the final year of the war, air battles could be as sprawling as those on the ground.

In The Origin of the Fighter Aircraft, historian Jon Guttman tells the engrossing story of how one of the most amazing inventions became a integral component of warfare. Balancing technical description, personalities, and battle accounts, the author demonstrates that by the end of World War I most of the fundamentals for modern aerial combat had been established.

Origin of the German Trauerspiel was Walter Benjamin’s first full, historically oriented analysis of modernity. Readers of English know it as “The Origin of German Tragic Drama,” but in fact the subject is something else—the play of mourning. Howard Eiland’s completely new English translation, the first since 1977, is closer to the German text and more consistent with Benjamin’s philosophical idiom.

Focusing on the extravagant seventeenth-century theatrical genre of the trauerspiel, precursor of the opera, Benjamin identifies allegory as the constitutive trope of the Baroque and of modernity itself. Allegorical perception bespeaks a world of mutability and equivocation, a melancholy sense of eternal transience without access to the transcendentals of the medieval mystery plays—though no less haunted and bedeviled. History as trauerspiel is the condition as well as subject of modern allegory in its inscription of the abyssal.

Benjamin’s investigation of the trauerspiel includes German texts and late Renaissance European drama such as Hamlet and Calderón’s Life Is a Dream. The prologue is one of his most important and difficult pieces of writing. It lays out his method of indirection and his idea of the “constellation” as a key means of grasping the world, making dynamic unities out of the myriad bits of daily life. Thoroughly annotated with a philological and historical introduction and other explanatory and supplementary material, this rigorous and elegant new translation brings fresh understanding to a cardinal work by one of the twentieth century’s greatest literary critics.

This book presents an insider's account of Columbia's internal conflict. At the forefront are the Revolutionary Armed Forces of Colombia-People's Army (FARC-EP).

Although they are one of the most powerful military forces in Latin American history, little is known about the FARC-EP. James J. Brittain explains where and why this political military movement came into existence and assesses whether the methods employed by the insurgency have the potential to free those marginalised in Colombia.

As democratic socialism develops in Venezuela and Bolivia, Brittain's fascinating study assesses the relevance of armed struggle to 21st century Latin American politics. This is an essential title for those wishing to develop a full understanding of the continent.

By evaluating the FARC-EP's actions, ideological construction, and their theoretical placement, the book gauges how this guerrilla movement relates to revolutionary theory and practice and through what tangible mechanisms, if any, they are creating a new Colombia.

Ernst Mayr is perhaps the most distinguished biologist of the twentieth century, and Systematics and the Origin of Species may be one of his greatest and most influential books. This classic study, first published in 1942, helped to revolutionize evolutionary biology by offering a new approach to taxonomic principles and correlating the ideas and findings of modern systematics with those of other life science disciplines. This book is one of the foundational documents of the “Evolutionary Synthesis.” It is the book in which Mayr pioneered his new concept of species based chiefly on such biological factors as interbreeding and reproductive isolation, taking into account ecology, geography, and life history.

In his new Introduction for this edition, Mayr reflects on the place of this enduring work in the subsequent history of his field.

In this forcefully argued book, the leading evolutionary theorist of language draws on evidence from evolutionary biology, genetics, physical anthropology, anatomy, and neuroscience, to provide a framework for studying the evolution of human language and cognition.

Philip Lieberman argues forcibly that the widely influential theories of language's development, advanced by Chomskian linguists and cognitive scientists, especially those that postulate a single dedicated language "module," "organ," or "instinct," are inconsistent with principles and findings of evolutionary biology and neuroscience. He argues that the human neural system in its totality is the basis for the human language ability, for it requires the coordination of neural circuits that regulate motor control with memory and higher cognitive functions. Pointing out that articulate speech is a remarkably efficient means of conveying information, Lieberman also highlights the adaptive significance of the human tongue.

Fully human language involves the species-specific anatomy of speech, together with the neural capacity for thought and movement. In Lieberman's iconoclastic Darwinian view, the human language ability is the confluence of a succession of separate evolutionary developments, jury-rigged by natural selection to work together for an evolutionarily unique ability.

How did we become the linguistic, cultured, and hugely successful apes that we are? Our closest relatives--the other mentally complex and socially skilled primates--offer tantalizing clues. In Tree of Origin nine of the world's top primate experts read these clues and compose the most extensive picture to date of what the behavior of monkeys and apes can tell us about our own evolution as a species.

It has been nearly fifteen years since a single volume addressed the issue of human evolution from a primate perspective, and in that time we have witnessed explosive growth in research on the subject. Tree of Origin gives us the latest news about bonobos, the "make love not war" apes who behave so dramatically unlike chimpanzees. We learn about the tool traditions and social customs that set each ape community apart. We see how DNA analysis is revolutionizing our understanding of paternity, intergroup migration, and reproductive success. And we confront intriguing discoveries about primate hunting behavior, politics, cognition, diet, and the evolution of language and intelligence that challenge claims of human uniqueness in new and subtle ways.

Tree of Origin provides the clearest glimpse yet of the apelike ancestor who left the forest and began the long journey toward modern humanity.

We know the universe has a history, but does it also have a story of self-creation to tell? Yes, in Roy R. Gould’s account. He offers a compelling narrative of how the universe—with no instruction other than its own laws—evolved into billions of galaxies and gave rise to life, including humans who have been trying for millennia to comprehend it. Far from being a random accident, the universe is hard at work, extracting order from chaos.

Making use of the best current science, Gould turns what many assume to be true about the universe on its head. The cosmos expands inward, not outward. Gravity can drive things apart, not merely together. And the universe seems to defy entropy as it becomes more ordered, rather than the other way around. Strangest of all, the universe is exquisitely hospitable to life, despite its being constructed from undistinguished atoms and a few unexceptional rules of behavior. Universe in Creation explores whether the emergence of life, rather than being a mere cosmic afterthought, may be written into the most basic laws of nature.

Offering a fresh take on what brought the world—and us—into being, Gould helps us see the universe as the master of its own creation, not tethered to a singular event but burgeoning as new space and energy continuously stream into existence. It is a very old story, as yet unfinished, with plotlines that twist and churn through infinite space and time.

Charles Darwin is often credited with discovering evolution through natural selection, but the idea was not his alone. The naturalist Alfred Russel Wallace, working independently, saw the same process at work in the natural world and elaborated much the same theory. Their important scientific contributions made both men famous in their lifetimes, but Wallace slipped into obscurity after his death, while Darwin's renown grew. Dispelling the misperceptions that continue to paint Wallace as a secondary figure, James Costa reveals the two naturalists as true equals in advancing one of the greatest scientific discoveries of all time.

Analyzing Wallace's "Species Notebook," Costa shows how Wallace's methods and thought processes paralleled Darwin's, yet inspired insights uniquely his own. Kept during his Southeast Asian expeditions of the 1850s, the notebook is a window into Wallace's early evolutionary ideas. It records his evidence-gathering, critiques of anti-evolutionary arguments, and plans for a book on "transmutation." Most important, it demonstrates conclusively that natural selection was not some idea Wallace stumbled upon, as is sometimes assumed, but was the culmination of a decade-long quest to solve the mystery of the origin of species.

Wallace, Darwin, and the Origin of Species also reexamines the pivotal episode in 1858 when Wallace sent Darwin a manuscript announcing his discovery of natural selection, prompting a joint public reading of the two men's papers on the subject. Costa's analysis of the "Species Notebook" shines a new light on these readings, further illuminating the independent nature of Wallace's discoveries.
