Researchers who study ancient human diets tend to focus on meat eating, since the practice of butchery is very apparent in the archaeological record. In this volume, Julie Lesnik brings a different food source into view, tracing evidence that humans and their hominin ancestors also consumed insects throughout the entire course of human evolution. Lesnik investigates the role of insects in the diets of hunter-gatherers and our nonhuman primate cousins in order to deduce what insect consumption looked like in the past. She approaches the question from the perspectives of primatology, sociocultural anthropology, reproductive physiology, and paleoanthropology. Lesnik posits that women would likely spend more time foraging for and eating insects than men, arguing that this pattern is important to note because women are too often ignored in reconstructions of ancient human behavior. Because of the abundance of insects and the low risk of acquiring them, insects were a reliable food source that mothers used to feed their families over the past five million years. Although they are consumed worldwide to this day, insects are not usually considered to be food in Western societies. Tying together ancient history with our modern lives, Lesnik points out that insects are a highly nutritious and very sustainable food. Lesnik believes that if we accept that edible insects are a part of the human legacy, we may have new conversations about what is good to eat-both in past diets and for the future of food.

Virtually all aspects of human behavior show enormous variation both within and between cultural groups, including material culture, social organization and language. Thousands of distinct cultural groups exist: about 6,000 languages are spoken today, and it is thought that a far greater number of languages existed in the past but became extinct. Using a Darwinian approach, this book seeks to explain this rich cultural variation. There are a number of theoretical reasons to believe that cultural diversification might be tree-like, that is phylogenetic: material and non-material culture is clearly inherited by descendants, there is descent with modification, and languages appear to be hierarchically related. There are also a number of theoretical reasons to believe that cultural evolution is not tree-like: cultural inheritance is not Mendelian and can indeed be vertical, horizontal or oblique, evidence of borrowing abounds, cultures are not necessarily biological populations and can be transient and complex. Here, for the first time, this title tackles these questions of cultural evolution empirically and quantitatively, using a range of case studies from Africa, the Pacific, Europe, Asia and America. A range of powerful theoretical tools developed in evolutionary biology is used to test detailed hypotheses about historical patterns and adaptive functions in cultural evolution. Evidence is amassed from archaeological, linguist and cultural datasets, from both recent and historical or pre-historical time periods. A unifying theme is that the phylogenetic approach is a useful and powerful framework, both for describing the evolutionary history of these traits, and also for testing adaptive hypotheses about their evolution and co-evolution. Contributors include archaeologists, anthropologists, evolutionary biologists and linguists, and this book will be of great interest to all those involved in these areas.

The book is the first thorough study of the role of phosphorus chemistry in the origin of life. This book starts with depiction of the phosphorus role in life creation and evolution. Then it outlines in vital processes how different phosphorus-containing compounds participate as biomarker in life evolution. Written by renowned scientists, it is suitable for researchers and students in organic phosphorus chemistry and biochemistry.

Wallace noticed on expeditions to the Amazon and the Malay archipelego that mammals in Southeast Asia are more advanced than their Australian cousins. His suggestion was that the two continents had split before the better adapted mammals had evolved in Asia. The isolated Australian marsupials were able to thrive, whilst those in Asia were driven to extinction by competition from more advanced mammals. This led to his theory of natural selection, which he presented to the Linnean Society in 1858 with Charles Darwin. This volume reprints those papers presented to the Linnean Society.

An enchanting biography of the most resonant - and most necessary - chemical element on Earth. Carbon. It is the building block of every cell that makes up every living thing. It is the essential component of the food we eat, the fuel we burn, the wood we use and the air we breathe. It is worth billions as a luxury and half a trillion as a necessity, but there are still mysteries to be solved about the element that can be both diamond and coal. Where does it come from, what does it do, and why, above all, does life need it? In Symphony in C, leading carbon scientist Robert M. Hazen takes us on a vibrant journey through the origin and evolution of life's most widespread element. The story unfolds in four movements - Earth, Air, Fire and Water - and transports us through nearly 14 billion years of cosmic history, explaining how carbon is formed in the hearts of stars and why all life forms - earthbound or alien - use it as the basis of their biology. Symphony in C is a sweeping chronicle of carbon from its birth amidst the stars to its unknowable life cycle deep within the Earth's core and its role in the evolution of all life in the universe.

Fritz Muller (1821-1897), though not as well known as his colleague Charles Darwin, belongs in the cohort of great nineteenth-century naturalists. Recovering Muller's legacy, David A. West describes the close intellectual kinship between Muller and Darwin and details a lively correspondence that spanned seventeen years. The two scientists, despite living on separate continents, often discussed new research topics and exchanged groundbreaking ideas that unequivocally moved the field of evolutionary biology forward. Muller was unique among naturalists testing Darwin's theory of natural selection because he investigated an enormous diversity of plants and animals, corresponded with prominent scientists, and published important articles in Germany, England, the United States, and Brazil. Darwin frequently praised Muller's powers of observation and interpretation, counting him among those scientists whose opinions he valued most. Despite the importance and scope of his work, however, Muller is known for relatively few of his discoveries. West remedies this oversight, chronicling the life and work of this remarkable and overlooked man of science.

This pivotal volume in the definitive edition of Charles Darwin's letters covers the year 1871, the year in which Descent of Man, Darwin's first public statement on human evolution, was published. The large number of letters in this year - more than 800 - reflects the excitement this caused. Darwin depended on correspondence to collect data from a growing network of contacts all over the world and to discuss his emerging ideas with colleagues, many of whom he never met in person. This year also saw the marriage of Darwin's daughter Henrietta, the first of his children to marry; the volume includes her personal journal of the year, published here for the first time, which complements letters that hint at her important role in her father's work as both commentator and editor. Notes and appendixes put these fascinating and wide-ranging letters in context, making them accessible to both scholars and general readers.

How Biology Confirms Our Intuition That Life Is Designed

When Charles Darwin finished The Origin of Species, he thought that he had explained every clue, but one. Though his theory could explain many facts, Darwin knew that there was a significant event in the history of life that his theory did not explain. During this event, the -Cambrian explosion, - many animals suddenly appeared in the fossil record without apparent ancestors in earlier layers of rock. In Darwin's Doubt, Stephen C. Meyer tells the story of the mystery surrounding this explosion of animal life--a mystery that has intensified, not only because the expected ancestors of these animals have not been found, but because scientists have learned more about what it takes to construct an animal. During the last half century, biologists have come to appreciate the central importance of biological information--stored in DNA and elsewhere in cells--to building animal forms.Expanding on the compelling case he presented in his last book, Signature in the Cell, Meyer argues that the origin of this information, as well as other mysterious features of the Cambrian event, are best explained by intelligent design, rather than purely undirected evolutionary processes.

Referring to Lewis Carroll's Red Queen from Through the Looking-Glass, a character who has to keep running to stay in the same place, Matt Ridley demonstrates why sex is humanity's best strategy for outwitting its constantly mutating internal predators. The Red Queen answers dozens of other riddles of human nature and culture -- including why men propose marriage, the method behind our maddening notions of beauty, and the disquieting fact that a woman is more likely to conceive a child by an adulterous lover than by her husband. Brilliantly written, The Red Queen offers an extraordinary new way of interpreting the human condition and how it has evolved.

Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production.

Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use.

Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources.

This book had an ambitious goal in bringing together a sample of the world s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.

Here is a book for everyone who has an interest in how our planet works, what has happened during its 4,550 million year history and what might happen in the future. It tells how Earth scientists study the pattern of events that have shaped the planet and guided the evolution of life on Earth. In clear and simple language it describes how the effects of these events are measured and the careful detective work needed to unravel the extraordinary complexity of Earth history. The latest advances in dating methods, including the detection of regular patterns of global climate change, are explained and illustrated with real case histories. Our environment is unexpectedly unstable.
Dramatic and catastrophic changes in the environment have directed the evolution of life and the rise of Man, and we can expect similar events in the future. If we are to control their effects, we will have to understand what to expect - and what could happen if we try to intervene in the 'natural' development of our home, the Earth.

The discovery in the 1920s of a huge cache of fossils in the Gobi Desert fuelled a mania for dinosaurs that continues to the present. But the original goal of the expedition was to search for the origins of man. Henry Fairfield Osborn (1857-1935), director of the American Museum of Natural History, stood at the forefront of the debate over human evolution and the expedition aimed to prove his theory of human origins. Osborn rejected the idea of primate ancestry and constructed a non-Darwinian theory that the evolution of man was the long adventurous story of individuals and groups exerting personal will-power and inborn characteristics to achieve both biological and spiritual success. It is an idea that still echoes today. Study of Osborn's thinking, however, has been obscured by the perception that racism influenced his theories. Brian Regal paints a different and more textured picture in this book - he shows that Osborn's views on race, like his political ideas, were motivated by his science, itself grounded in religious doctrine. His belief in the Central Asian origins of man, his role as an activist for eugenic reform and immigration controls, his support for Nordicism, his place in the 'New' versus 'Old' biology debate, his role in the Christian Fundamentalist controversy, the Scopes Monkey trial, and finally his construction of the 'Dawn Man' hypothesis - all stemmed from his desire to support his human evolution theory, and point the way to salvation. This biography charts Osborn's intellectual development, from its roots in the eclectic Christianity of his mother, through his student days with Arnold Guyot, James McCosh, and T.H. Huxley, to his mature work at the American Museum. It examines his trials and tribulations, friendships and conflicts, and the world in which he lived: all contributed to the construction of his theory. It is the dramatic story of a man holding onto ideas that for him represented the very meaning of life itself.

Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role in improving our understanding of evolution, in particular of morphological stasis. It also explores how the recognition of cryptic species is intrinsically linked to the so-called 'species problem', the lack of a unifying species concept in biology, and suggests alternative approaches. Bringing together a range of perspectives from practicing taxonomists, the book presents case studies of cryptic species across a range of animal and plant groups. It will be an invaluable text for all biologists interested in species and their delimitation, definition, and purpose, including undergraduate and graduate students and researchers.

The Anthropocene defines the here-and-now time period on Earth of indelible (and possibly irreversible) human disturbance to the natural world, from habitat destruction and mass extinction to global climate change. To ameliorate and repair the damage that threatens the world's dwindling resources and our very existence, humanity is enacting massive interventions to fuse modern technologies with long established natural processes. Advances in genetic engineering have put us on the cusp of directly shaping the DNA of every living organism (including ourselves), as well as determining the evolution of completely novel species. The author invites the reader to explore how humans have manipulated the ancient forces of evolution and the future possibilities of genetic engineering for conservation and rewilding, de-extinction, and even the creation of viable populations of entirely new species. To entertain such possibilities of synthetic biology, he forces us to wrestle with the threats and ethical conundrums that surround the unintended consequences, as well as the values that humanity places on authenticity in nature. In so doing, this accessible and thought-provoking book explores the potential future of life on planet Earth.

This volume reaches beyond the controversy surrounding the teaching and learning of evolution in the United States, specifically in regard to the culture, politics, and beliefs found in the Southeast. The editors argue that despite a deep history of conflict in the region surrounding evolution, there is a wealth of evolution research taking place-from biodiversity in species to cultural evolution and human development. In fact, scientists, educators, and researchers from around the United States have found their niche in the South, where biodiversity is high, culture runs deep, and the pace is just a little bit slower.

A fully updated edition of one of the most original accounts of evolution ever written, featuring new fractal diagrams, six new 'tales' and the latest scientific developments. THE ANCESTOR'S TALE is a dazzling, four-billion-year pilgrimage to the origins of life: Richard Dawkins and Yan Wong take us on an exhilarating reverse journey through evolution, from present-day humans back to the microbial beginnings of life. It is a journey happily interrupted by meetings of fellow modern animals (as well as plants, fungi and bacteria) similarly tracing their evolutionary path back through history. As each evolutionary pilgrim tells their tale, Dawkins and Wong shed light on topics such as speciation, sexual selection and extinction. Written with unparalleled wit, clarity and intelligence; taking in new scientific discoveries of the past decade; and including new 'tales', illustrations and fractal diagrams, THE ANCESTOR'S TALE shows us how remarkable we are, how astonishing our history, and how intimate our relationship with the rest of the living world.

Fossil crinoids are exceptionally suited to deep-time studies of community paleoecology and niche partitioning. By merging ecomorphological trait and phylogenetic data, this Element summarizes niche occupation and community paleoecology of crinoids from the Bromide fauna of Oklahoma (Sandbian, Upper Ordovician). Patterns of community structure and niche evolution are evaluated over a ~5 million-year period through comparison with the Brechin Lagerstatte (Katian, Upper Ordovician). The authors establish filtration fan density, food size selectivity, and body size as major axes defining niche differentiation, and niche occupation is strongly controlled by phylogeny. Ecological strategies were relatively static over the study interval at high taxonomic scales, but niche differentiation and specialization increased in most subclades. Changes in disparity and species richness indicate the transition between the early-middle Paleozoic Crinoid Evolutionary Faunas was already underway by the Katian due to ecological drivers and was not triggered by the Late Ordovician mass extinction.

Recent interest in the evolution of the social contract is extended by providing a throughly naturalistic, evolutionary account of the biological underpinnings of a social contract theory of morality. This social contract theory of morality (contractevolism) provides an evolutionary justification of the primacy of a moral principle of maximisation of the opportunities for evolutionary reproductive success (ERS), where maximising opportunities does not entail an obligation on individuals to choose to maximise their ERS. From that primary principle, the moral principles of inclusion, individual sovereignty (liberty) and equality can be derived. The implications of these principles, within contractevolism, are explored through an examination of patriarchy, individual sovereignty and copulatory choices, and overpopulation and extinction. Contractevolism is grounded in evolutionary dynamics that resulted in humans and human societies. The most important behavioural consequences of evolution to contractevolism are reciprocity, cooperation, empathy, and the most important cognitive consequences are reason and behavioural modification.

Evolution of Learning and Memory Mechanisms is an exploration of laboratory and field research on the many ways that evolution has influenced learning and memory processes, such as associative learning, social learning, and spatial, working, and episodic memory systems. This volume features research by both outstanding early-career scientists as well as familiar luminaries in the field. Learning and memory in a broad range of animals are explored, including numerous species of invertebrates (insects, worms, sea hares), as well as fish, amphibians, birds, rodents, bears, and human and nonhuman primates. Contributors discuss how the behavioral, cognitive, and neural mechanisms underlying learning and memory have been influenced by evolutionary pressures. They also draw connections between learning and memory and the specific selective factors that shaped their evolution. Evolution of Learning and Memory Mechanisms should be a valuable resource for those working in the areas of experimental and comparative psychology, comparative cognition, brain-behavior evolution, and animal behavior.
