The scientific understanding of arthropod phylogeny and evolution has changed significantly in recent decades. One of the most momentous alterations involved crustaceans, which are not a monophyletc group, but are part of a larger group along with insects: Pancrustacea. The old ideas surrounding crustacean evolution have served scientists well for many years; it is now time to turn toward new research by embracing the results derived from investigations conducted largely within this century. For example, new definitions have arisen from sources across several fields of study, and Frederick R. Schram and Stefan Koenemann have created a book that explores paleobiodiversity and the diversity of modern body plans. Developments within ontogenetic studies continue to generate remarkable insights into crustaceomorph evolution in regard to patterns of embryology and a revolution in the application of development genetics. Phylogeny techniques of analysis and new sources of data derived from molecular sequencing and genetic studies have forced scientists to consider new hypotheses concerning the interrelationships of all the pancrustaceans, both the crustaceomorphs and Hexapoda. Yet, some fossil groups still remain enigmatic (Thylacocephala). Despite this, research into fossils (even if incompletely understood) fills in gaps of our knowledge of paleobiodiversity, and it's useful for many things, including analyzing the origin and early evolution of Hexapoda. Evolution and Phylogeny of Pancrustacea demonstrates the use of multiple alternative hypotheses and other techniques through the well-executed presentation of diverse data sources involving Pancrustacea. Readers are left with clues to great mysteries, including the possible pathways of evolution within marine arthropods.
Knowledge of the evolutionary history of birds has much improved in recent decades. Fossils from critical time periods are being described at unprecedented rates and modern phylogenetic analyses have provided a framework for the interrelationships of the extant groups. This book gives an overview of the avian fossil record and its paleobiological significance, and it is the only up-to-date textbook that covers both Mesozoic and more modern-type Cenozoic birds in some detail. The reader is introduced to key features of basal avians and the morphological transformations that have occurred in the evolution towards modern birds. An account of the Cenozoic fossil record sheds light on the biogeographic history of the extant avian groups and discusses fossils in the context of current phylogenetic hypotheses. This review of the evolutionary history of birds not only addresses students and established researchers, but it may also be a useful source of information for anyone else with an interest in the evolution of birds and a moderate background in biology and geology.
Race and Human Diversity is an introduction to the study of human diversity in both its biological and cultural dimensions. Robert L. Anemone examines the biological basis of human difference and how humans have biologically and culturally adapted to life in different environments. The book discusses the history of the race concept, evolutionary theory, human genetics, and the connections between racial classifications and racism. It invites students to question the existence of race as biology, but to recognize race as a social construction with significant implications for the lived experience of individuals and populations. This second edition has been thoroughly revised, with new material on human genetic diversity, developmental plasticity and epigenetics. There is additional coverage of the history of eugenics; race in US history, citizenship and migration; affirmative action; and white privilege and the burden of race. Fully accessible for undergraduate students with no prior knowledge of genetics or statistics, this is a key text for any student taking an introductory class on race or human diversity.
A new human species will soon come to co-exist with us. This new species, 'Homo nouveau,' will be created using artificial intelligence and genetic engineering; both important tools which are in their infancy. Not only are the science and technology relatively new, but their implications in the mind of the general public are also only just beginning to enter our collective consciousness. This book expands on the research done for the author's previous book, What Comes After Homo Sapiens? Written by a medical professional and independent consultant to healthcare IT companies, The Fourth Great Transformation explores the questions of what this new species will look like, how we as humans will get along with them, and the potential threats and opportunities that will come along with genetically modified humans.
The history of life on earth is largely reconstructed from time-averaged accumulations of fossils. A glimpse at ecologic-time attributes and processes is relatively rare. However, the time-sensitive and predictability of echinoderm disarticulation makes them model organisms to determine post-mortem transportation and allows recognition of ecological-time data within paleocommunity accumulations. Unlike many other fossil groups, this has allowed research on many aspects of echinoderms and their paleocommunities, such as the distribution of soft tissues, assessment of the amount of fossil transportation prior to burial, determination of intraspecific variation, paleocommunity composition, estimation of relative abundance of taxa in paleocommunities, determination of attributes of niche differentiation, etc. Crinoids and echinoids have received the most amount of taphonomic research, and the patterns present in these two groups can be used to develop a more thorough understanding of all echinoderm clades.
The quantification of morphology through time is a vital tool in elucidating macroevolutionary patterns. Studies of disparity require intense effort but can provide insights beyond those gained using other methodologies. Over the last several decades, studies of disparity have proliferated, often using echinoderms as a model organism. Echinoderms have been used to study the methodology of disparity analyses and potential biases as well as documenting the morphological patterns observed in clades through time. Combining morphological studies with phylogenetic analyses or other disparate data sets allows for the testing of detailed and far-reaching evolutionary hypotheses.
Echinoderms elaborate a calcite skeleton composed of numerous plates with a distinct microstructure (stereom) that can be modelled into different shapes thanks to the use of a transient amorphous calcium carbonate (ACC) precursor phase and the incorporation of an intraorganic matrix during biomineralization. A variety of different types of stereom microarchitecture have been distinguished, each of them optimized for a specific function. For instance, a regular, galleried stereom typically houses collagenous ligaments, whereas an irregular, fine labyrinthic stereom commonly bears muscles. Epithelial tissues, in turn, are usually associated with coarse and dense stereom microfabrics. Stereom can be preserved in fossil echinoderms and a wide array of investigating methods are available. As many case studies have shown, a great deal of important paleobiological and paleoecological information can be decoded by studying the stereom microstructure of extinct echinoderms.
The theory of evolution unites the past, present, and future of living things. It puts humanity's place in the universe into necessary perspective. Despite a history of controversy, the evidence for evolution continues to accumulate as a result of many separate strands of amazing scientific sleuthing. In The Story of Evolution in 25 Discoveries, Donald R. Prothero explores the most fascinating breakthroughs in piecing together the evidence for evolution. In twenty-five vignettes, he recounts the dramatic stories of the people who made crucial discoveries, placing each moment in the context of what it represented for the progress of science. He tackles topics like what it means to see evolution in action and what the many transitional fossils show us about evolution, following figures from Darwin to lesser-known researchers as they unlock the mysteries of the fossil record, the earth, and the universe. The book also features the stories of animal species strange and familiar, including humans-and our ties to some of our closest relatives and more distant cousins. Prothero's wide-ranging tales showcase awe-inspiring and bizarre aspects of nature and the powerful insights they give us into the way that life works. Brisk and entertaining while firmly grounded in fundamental science, The Story of Evolution in 25 Discoveries is a captivating read for anyone curious about the evidence for evolution and what it means for humanity.
In this provocative work, noted social and economic theorist Graeme D. Snooks exposes fatal flaws in the foundations of the Darwinian theory of evolution, which he deems an "artificial algorithm," as well as the neo-Darwinian synthesis adopted by many social scientists. Utilizing the historical method, Snooks develops a remarkable replacement theory of evolution, which he calls the "dynamic-strategy" theory. While the neo-Darwinian position places too great an emphasis on genetic change giving rise to untenable but popular concepts such as the "selfish gene" and fails to explain the fluctuating fortunes of life's most successful species (mankind), Snooks' framework starts by systematically observing the broad patterns of life and human society. The resultant realist theory of life posits life as a strategic pursuit (rather than a game of chance) in which organisms adopt dynamic strategies (only one of which is genetic change) to survive and prosper. Organisms' and species' progress is achieved through "strategic selection" a concept that displaces the "divine selection" of creationists and the "natural selection" of Darwinists. This new theory reveals the organism as empowered, rather than as the plaything of gods, genes, or blind chance; and it provides a new basis for humanism."

An accessible graphic introduction to evolution for the most
science-phobic reader
An account of all the new and surprising evidence now available for the beginnings of the earliest civilizations that contradict the standard narrative Why did humans abandon hunting and gathering for sedentary communities dependent on livestock and cereal grains, and governed by precursors of today's states? Most people believe that plant and animal domestication allowed humans, finally, to settle down and form agricultural villages, towns, and states, which made possible civilization, law, public order, and a presumably secure way of living. But archaeological and historical evidence challenges this narrative. The first agrarian states, says James C. Scott, were born of accumulations of domestications: first fire, then plants, livestock, subjects of the state, captives, and finally women in the patriarchal family-all of which can be viewed as a way of gaining control over reproduction. Scott explores why we avoided sedentism and plow agriculture, the advantages of mobile subsistence, the unforeseeable disease epidemics arising from crowding plants, animals, and grain, and why all early states are based on millets and cereal grains and unfree labor. He also discusses the "barbarians" who long evaded state control, as a way of understanding continuing tension between states and nonsubject peoples.

Evolution: The Basics is an engaging introduction to the history, development and science of the theory of evolution. Beginning pre-Darwin and concluding with the latest research and controversies, readers are introduced to the origins of the idea of evolution, the ways in which it has developed and been adapted over time and the science underpinning it all. Topics addressed include:
"The irresistible enthusiasm of Great Adaptations couldn't come at a better time."-David P. Barash, Wall Street Journal "Be very amazed."-Carl Safina, author of Beyond Words and Becoming Wild How one scientist unlocked the secrets behind some of nature's most astounding animals From star-nosed moles that have super-sensing snouts to electric eels that paralyze their prey, animals possess unique and extraordinary abilities. In Great Adaptations, Kenneth Catania presents an entertaining and engaging look at some of nature's most remarkable creatures. Telling the story of his biological detective work, Catania sheds light on the mysteries behind the behaviors of tentacled snakes, tiny shrews, zombie-making wasps, and more. He shows not only how studying these animals can provide deep insights into how life evolved, but also how scientific discovery can be filled with adventure and fun. Beginning with the star-nosed mole, Catania reveals what the creature's nasal star is actually for, and what this tells us about how brains work. He explores how the deceptive hunting strategy of tentacled snakes leads prey straight to their mouths, how eels use electricity to control other animals, and why emerald jewel wasps make zombies out of cockroaches. He also solves the enigma of worm grunting-a traditional technique in which earthworms are enticed out of the ground-by teaming up with professional worm grunters. Catania demonstrates the merits of approaching science with an open mind, considers the role played by citizen scientists, and illustrates that most animals have incredible, hidden abilities that defy our imagination. Examining some strange and spectacular creatures, Great Adaptations offers a wondrous journey into nature's grand designs.
How did life evolve on Earth? The answer to this question can help us understand our past and prepare for our future. Although evolution provides credible and reliable answers, polls show that many people turn away from science, seeking other explanations with which they are more comfortable. In the book Science, Evolution, and Creationism, a group of experts assembled by the National Academy of Sciences and the Institute of Medicine explain the fundamental methods of science, document the overwhelming evidence in support of biological evolution, and evaluate the alternative perspectives offered by advocates of various kinds of creationism, including "intelligent design." The book explores the many fascinating inquiries being pursued that put the science of evolution to work in preventing and treating human disease, developing new agricultural products, and fostering industrial innovations. The book also presents the scientific and legal reasons for not teaching creationist ideas in public school science classes. Mindful of school board battles and recent court decisions, Science, Evolution, and Creationism shows that science and religion should be viewed as different ways of understanding the world rather than as frameworks that are in conflict with each other and that the evidence for evolution can be fully compatible with religious faith. For educators, students, teachers, community leaders, legislators, policy makers, and parents who seek to understand the basis of evolutionary science, this publication will be an essential resource.

The cognitive abilities of birds are remarkable: hummingbirds integrate spatial and temporal information about food sources, day-old chicks have a sense of numbers, parrots can make and use tools, and ravens have sophisticated insights in social relationships. This volume describes the full range of avian cognitive abilities, the mechanisms behind such abilities and how they relate to the ecology of the species. Synthesising the latest research in avian cognition, a range of experts in the field provide first-hand insights into experimental procedures, outcomes and theoretical advances, including a discussion of how the findings in birds relate to the cognitive abilities of other species, including humans. The authors cover a range of topics such as spatial cognition, social learning, tool use, perceptual categorization and concept learning, providing the broader context for students and researchers interested in the current state of avian cognition research, its key questions and appropriate experimental approaches.
Sexual conflict permeates ancient religions, from injunctions about thy neighbor's wife to the sexual obligations of marriage. It is etched in written laws that dictate who can and cannot have sex with whom. Its manifestations shape our sexual morality, evoking approving accolades or contemptuous condemnation. It produces sexual double standards that flourish even in the most sexually egalitarian cultures on earth. And although every person alive struggles with sexual conflict, most of us see only the tip of the iceberg: dating deception, a politician's unsavory grab, the slow crumbling of a once-happy marriage, a romantic breakup that turns nasty. Bad Men shows that this "battle of the sexes" is deeper and far more pervasive than anyone has recognized, revealing the hidden roots of sexual conflict -- roots that originated over deep evolutionary time -- which characterise our sexual psychology. Providing novel insights into our minds and behaviours, Bad Men presents a unifying new theory of sexual conflict and offers practical advice for men and women seeking to avoid it.
"Lucy is a 3.2-million-year-old skeleton who has become the
spokeswoman for human evolution. She is perhaps the best known and
most studied fossil hominid of the twentieth century, the benchmark
by which other discoveries of human ancestors are judged.""-"From
"Lucy's Legacy "From the Hardcover edition."
Current knowledge of the genetic, epigenetic, behavioural and symbolic systems of inheritance requires a revision and extension of the mid-twentieth-century, gene-based, 'Modern Synthesis' version of Darwinian evolutionary theory. We present the case for this by first outlining the history that led to the neo-Darwinian view of evolution. In the second section we describe and compare different types of inheritance, and in the third discuss the implications of a broad view of heredity for various aspects of evolutionary theory. We end with an examination of the philosophical and conceptual ramifications of evolutionary thinking that incorporates multiple inheritance systems.
The Wonder of Flight. The Science of Evolution. From both, Richard Dawkins weaves a fascinating and beautifully illustrated account of how nature and humans have learned to overcome the pull of gravity and take to the skies. Do you sometimes dream you can fly like a bird? Gliding effortlessly above the treetops, soaring and swooping, playing and dodging through the third dimension. Computer games, virtual reality headsets, and some drugs can lift our imagination and fly us through fabled, magical spaces. But it's not the real thing. No wonder some of the past's greatest minds, including Leonardo da Vinci's, have yearned for flying machines and struggled to design them. Flights of Fancy is a book about flying – all the different ways of defying gravity that have been discovered by humans over the centuries and by other animals over the millions of years, from the mythical Icarus, to the sadly extinct but magnificent bird Argentavis magnificens, to the Wright Flyer and the 747. But it also means flights of digression into more general ideas and principles that take off from a discussion about actual flight. Fascinating and elegantly written, this is a unique collaboration between one of the world's leading zoologists and a talented artist, and perfect for enquiring teenage minds.
