Annelida is a diverse group of animals, commonly referred to as segmented worms and currently comprising around 14000 described species. Found in most marine and freshwater areas, annelids have also successfully occupied many subterranean habitats. This volume documents annelid reproduction in the context of their phylogenetic relationships. It presents an introduction and overview to the current systematics of annelids and provides reviews to broad aspects of reproduction across Annelida. The chapters cover oogenesis, sperm, mating, early development, larval development and larval ecology. The book also covers some of the major clades (or purported clades) of annelids and addresses similar issues. The final chapter covers some of the more problematic annelid groups in terms of their phylogenetic placement.

One of the little known species in the danger of extinction, gymophionan amphibians, are also known as caecilians or apoda. Gymnophiona contains 154 species belonging to 34 genera and 6 families. For many years, studies on the Gymnophiona were disparate and still only a few species have been deeply studied. Fortunately, in recent years, some new works have been published on their systematics, using both the classical methods as well as immunology and molecular biology. New data have also been obtained on the biology, life history, reproductive biology, endocrinology and embryonic development of several species. These fascinating aspects along with other important ones on gymnophionan studies are ably reviewed in this book.

The extended continental South American turtle record (Norian to Lujanian) allows us to follow the evolution of this reptile clade from its origins. Several significant stem turtle taxa such as: Palaeochersis talampayensis and Condorchelys antiqua provide information on the first steps of turtle evolution. Others such as: Chubutemys copelloi or Patagoniaemys gasparinae provide clues to the origin of the bizarre horned tortoises of the clade Meiolaniidae. The panpleurodiran species such as Notoemys laticentralis or Notoemys zapatocaensis shed light on the origin of modern pleurodiran turtles. This book explores aquatic and terrestrial cryptodiran turtles, South Gondwana pleurodiran turtles, North Gondwana pleurodiran turtles; Meiolaniforms and early differentiation of Mesozoic turtles.

Scientists have developed a featherless chicken designed to make industrial chicken production more efficient, while specially trained Pacific bottlenose dolphins are being deployed in the Persian Gulf to disarm mines and protect our Navy. Everyone knows Darwin's theory of natural selection, but what about his idea of artificial selection--how humans, not nature, rework natural organisms to meet our needs? Industrializing Organisms brings us to the threshold of the new field of evolutionary history--from the mobilization of war horses in the 19th century to today's engineered plants and manipulated animals.

Darwin's theory of evolution by natural selection was based on the observation that there is variation between individuals within the same species. This fundamental observation is a central concept in evolutionary biology. However, variation is only rarely treated directly. It has remained peripheral to the study of mechanisms of evolutionary change. The explosion of knowledge in genetics, developmental biology, and the ongoing synthesis of evolutionary and developmental biology has made it possible for us to study the factors that limit, enhance, or structure variation at the level of an animals' physical appearance and behavior. Knowledge of the significance of variability is crucial to this emerging synthesis. This volume situates the role of variability within this broad framework, bringing variation back to the center of the evolutionary stage.
-Provides an overview of current thinking on variation in evolutionary biology, functional morphology, and evolutionary developmental biology
-Written by a team of leading scholars specializing on the study of variation
-Reviews of statistical analysis of variation by leading authorities
-Key chapters focus on the role of the study of phenotypic variation for evolutionary, developmental, and post-genomic biology

In United States public schools, the content being taught in all subjects is determined by specialists who have the expertise necessary for the task. Parents don't insist on their opinions being part of curricular decisions. History, mathematics and literature classes, for example, generally enjoy full acceptance by parents and others. The science curriculum, however, is unique in that it has faced long-time opposition that shows little sign of lessening. Most notably, a controversy has arisen around biological evolution. Part history and part handbook, this carefully neutral work examines the origins of the opposition to biological evolution, its long and deep-seated history, and the reasons why it hasn't been resolved. Key terms - including creationism, evolution, intelligent design, and theory, among others - are defined at length, and erroneous understandings are addressed. Solutions are suggested so that the energies of school administrators and teachers may focus on their main task, the improvement of learning. State-by-state science standards are covered, and several models for biological science curricula are offered. Presented in a highly readable style, this study is intended for use by students, parents, teachers, school administrators, and community leaders alike, as well as others interested in the controversy.

This book describes the role of the obligate inhabitants of all vertebrate genomes-endogenous retroviruses, especially those emerged in genomes rather recently, during primate evolution. It specially focuses on human endogenous retroviruses as well as other retroelements.

The bestselling author of Fermat's Last Theorem and The Code Book tells the story of the brilliant minds that deciphered the mysteries of the Big Bang. A fascinating exploration of the ultimate question: how was our universe created? Albert Einstein once said: 'The most incomprehensible thing about the universe is that it is comprehensible.' Simon Singh believes geniuses like Einstein are not the only people able to grasp the physics that govern the universe. We all can. As well as explaining what the Big Bang theory actually is and why cosmologists believe it is an accurate description of the origins of the universe, this book is also the fascinating story of the scientists who fought against the established idea of an eternal and unchanging universe. Simon Singh, renowned for making difficult ideas much less daunting than they first seem, is the perfect guide for this journey. Everybody has heard of the Big Bang Theory. But how many of us can actually claim to understand it? With characteristic clarity and a narrative peppered with anecdotes and personal histories of those who have struggled to understand creation, Simon Singh has written the story of the most important theory ever.

Phylogenomics: A Primer, Second Edition is for advanced undergraduate and graduate biology students studying molecular biology, comparative biology, evolution, genomics, and biodiversity. This book explains the essential concepts underlying the storage and manipulation of genomics level data, construction of phylogenetic trees, population genetics, natural selection, the tree of life, DNA barcoding, and metagenomics. The inclusion of problem-solving exercises in each chapter provides students with a solid grasp of the important molecular and evolutionary questions facing modern biologists as well as the tools needed to answer them.

Where did we come from? Where are we going? Homo sapiens is the most successful, the most widespread and the most influential species ever to walk the Earth. In the blink of an evolutionary eye we have spread around the globe, taken control of Earth's biological and mineral resources, transformed the environment, discovered the secrets of the universe and travelled into space. Yet just 7 million years ago, we were just another species of great ape making a quiet living in the forests of East Africa. We do not know exactly what this ancestor was like, but it was no more likely than a chimpanzee or gorilla to sail across the ocean, write a symphony, invent a steam engine or ponder the meaning of existence. How did we get from there to here? Human Origins recounts the most astonishing evolutionary tale ever told. Discover how our ancestors made the first tentative steps towards becoming human, how we lost our fur but gained language, fire and tools, how we strode out of Africa, invented farming and cities and ultimately created modern civilisation - perhaps the only one of its kind in the universe. Meet your long-lost ancestors, the other humans who once shared the planet with us, and learn where the story might end. ABOUT THE SERIES New Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds. Designed for curious readers who want to know how things work and why, the Instant Expert series explores the topics that really matter and their impact on individuals, society, and the planet, translating the scientific complexities around us into language that's open to everyone, and putting new ideas and discoveries into perspective and context.

When the famous South African fish scientist Professor JLB Smith published Old Fourlegs - The Story of the Coelacanth in 1956 he created an international sensation. After all, this 400-million-year-old fish, known only from fossil remains, was thought to have become extinct around 66 million years ago! JLB Smith’s dramatic account of the discovery of the first and second coelacanths in 1938 and 1952 turned him into a cult figure and put South African science on the world map. His book was eventually published in six English editions and translated into nine foreign languages.

Mike Bruton’s The Annotated Old Fourlegs includes a facsimile reprint of the original book, to which he has added notes and images in the margins that provide an interesting and revealing commentary on Smith’s text, as well as new introductory and explanatory chapters that bring the coelacanth story up to date.

'Inferior is more than just a book. It's a battle cry - and right now, it's having a galvanising effect on its core fanbase' Observer Are women more nurturing than men? Are men more promiscuous than women? Are males the naturally dominant sex? And can science give us an impartial answer to these questions? Taking us on an eye-opening journey through science, Inferior challenges our preconceptions about men and women, investigating the ferocious gender wars that burn in biology, psychology and anthropology. Angela Saini revisits the landmark experiments that have informed our understanding, lays bare the problem of bias in research, and speaks to the scientists finally exploring the truth about the female sex. The result is an enlightening and deeply empowering account of women's minds, bodies and evolutionary history. Interrogating what these revelations mean for us as individuals and as a society, Inferior unveils a fresh view of science in which women are included, rather than excluded.

This book provides a comprehensive overview of the design, generation and characterization of minimal cell systems. Written by leading experts, it presents an in-depth analysis of the current issues and challenges in the field, including recent advances in the generation and characterization of reduced-genome strains generated from model organisms with relevance in biotechnology, and basic research such as Escherichia coli, Corynebacterium glutamicum and yeast. It also discusses methodologies, such as bottom-up and top-down genome minimization strategies, as well as novel analytical and experimental approaches to characterize and generate minimal cells. Lastly, it presents the latest research related to minimal cells of serveral microorganisms, e.g. Bacillus subtilis. The design of biological systems for biotechnological purposes employs strategies aimed at optimizing specific tasks. This approach is based on enhancing certain biological functions while reducing other capacities that are not required or that could be detrimental to the desired objective. A highly optimized cell factory would be expected to have only the capacity for reproduction and for performing the expected task. Such a hypothetical organism would be considered a minimal cell. At present, numerous research groups in academia and industry are exploring the theoretical and practical implications of constructing and using minimal cells and are providing valuable fundamental insights into the characteristics of minimal genomes, leading to an understanding of the essential gene set. In addition, research in this field is providing valuable information on the physiology of minimal cells and their utilization as a biological chassis to which useful biotechnological functions can be added.

The volume is collection of articles treating the topic of human improvement/enhancement from a variety of perspectives - philosophical, literary, medical, genetic, sociological, legal etc. The chapters in this volume treat not only those aspects that most immediately come to mind when one thinks of 'human enhancement', such as genetic engineering, cloning, artificial implants and artificial intelligence etc. Somewhat less obvious aspects include evolutionary perspectives in connection with the prolongation of the human lifespan, plastic surgery since its beginnings, and questions such as whether the distinction between 'natural' and 'artificial' can really be drawn at all and how it has been conceived across the ages, or what the legal implications are of recent developments and techniques. Many papers make links to the representation of these developments in popular culture, from Jules Verne through Aldous Huxley to the movie Gattaca, address the hopes and fears that come with them as well as the question how realistic these are. While all chapters are written by scientists at the international top of their respective fields, all are accessible to a non-specialist audience and eminently readable. We believe that they represent a state-of-the art overview of questions that are of interest to a large audience. The book thus targets a non-specialist audience with an interest in philosophical, sociological, scientific and legal issues involved in both traditional and recent matters concerning the desire of mankind to improve itself, the human body, the human mind and the human condition. It is unique in that it brings together all these aspects within a coherent and cohesive collection.

Mudskippers are amphibious fishes native to the Indo-West Pacific and tropical western Africa. Unlike most fishes, mudskippers emerse to forage, find mates, and defend territories. Adaptations to their morphology, physiology and behavior enable mudskippers to accommodate both aquatic and terrestrial habitats. For these traits, mudskippers have long captured the fascination of scientists, naturalists, and fish hobbyists. Some mudskipper taxa (e.g. Periophthalmodon spp., Periophthalmus spp., Boleophthalmus spp.) are readily observed on mudflats and mangrove forests during the ebb tide. Correspondingly, these conspicuous and widespread taxa are relatively well-studied. The autecology and basic biology for the remaing taxa (e.g. Apocryptodon spp. and Oxuderces spp.) are still poorly understood. Fishes Out of Water: Biology and Ecology of Mudskippers is the first comprehensive book to synthesize published scientific information and observation on these fishes. Two dozen subject experts present thorough overviews in fifteen distinct chapters. Contents span mudskipper anatomy, distribution, systematics, physiology, ecology, and conservation. Unique adaptations to terrestriality are discussed within the context of each chapter foci. This authoritative reference equips the reader with the basic foundation to understand mudskipper biology and ecology, while providing a framework in which emerging data are discussed. The book will be of interest to a broad range of students, researchers, and professionals in ichthyology, evolution, ecology, animal behavior, and comparative physiology.

Owen was the founder of the Natural History Museum, bringing the collections over from the British Museum. Although he was a supporter of evolutionary theory, he was reluctant to accept Darwin's version of evolution. This volume examines fossil evidence for change in species over time.

Moving away from his earlier belief in a short, catastrophic history of the Earth, Buckland's treatise envisages instead and propounds the theory of a course of progressive change that occurred as the Earth gradually cooled and became ready for human occupation. During this time, the creatures that first walked the Earth did not die out because they were poorly designed; God loved the dinosaurs and had adapted them to their various circumstances.

Huxley was one of the first adherents to Darwin's theory of evolution by natural selection and advanced its acceptance by scientists and the public. "Man's Place in Nature" was explicitly directed against Richard Owen, who had claimed that there were distinct differences between human brains and those of apes. Huxley demonstrated that ape and human brains were fundamentally similar in every anatomical detail, thus applying evolution to the human race.

Floral morphology is key for understanding floral evolution and plant identification. Floral diagrams are two-dimensional representations of flowers that replace extensive descriptions or elaborate drawings to convey information in a clear and unbiased way. Following the same outline as the first edition, this comprehensive guide includes updated and relevant literature, represents the latest phylogeny, and features 28 new diagrams. Diagrams are presented in the context of the most recent classifications, covering a variety of families and illustrating the floral diversity of major groups of plants. A strong didactic tool for observing and understanding floral structures, these diagrams are the obvious counterpart to any genetic study in flowering plants and to the discussion of major adaptations and evolutionary trends of flowers. This book is invaluable for researchers and students working on plant structure, development and systematics, as well as being an important resource for plant ecologists, evolutionary botanists and horticulturists.

Crustaceans, due to the great diversity of their body organization, segmentation patterns, tagmatization, limb types, larval forms, cleavage, and gastrulation modes, are highly desirable for the study of questions at the interface of evolution and development. Modern interest in evolutionary developmental biology (evo-devo) rests on the molecular genetic approach and a variety of molecular techniques have proven fruitful when performed on crustaceans.
Evolutionary Developmental Biology of Crustacea presents a comprehensive treatment of all aspects of the field, beginning with a discussion of the implications of the typological Bauplan and phylum concepts versus historical concepts such as ground pattern and monophylum for the formulation of conceptual questions in evo-devo. Following this, the authors present the results of Hox gene expression in various crustacean taxa, aspects of segment formation at the cellular and genetic levels, the formation of segmental structures such as neurons, ganglia, and limbs, and the role of morphological ontogenetic characters in resolving phylogenetic relationships.
By covering so many general aspects of crustacean development, morphology, and evolution, Evolutionary Developmental Biology of Crustacea serves as an indispensable reference for developmental and evolutionary biologists investigating the role of genetics in evolution and development.

There is a revolution underway in biology. It is based on a new perception of bodies and genes, in which the former are the end product of the latter within the continuum of evolution. Twenty five years after Richard Dawkins helped revolutionize our thinking about "selfish genes," it is time to re-evaluate. "Revolutionary Biology" explains in simple, vivid terms what this exciting approach has to offer, and then applies its stunning insights to human beings. This novel perspective, galvanizes our understanding of how evolution works, what living things are all about and, not least what it means to be human. The controversial disciplines of sociobiology and evolutionary psychology have generated startling insights into longstanding questions concerning the nature and purpose of families, altruism vs. selfishness, and free will vs. biological determinism. Written by one of its foremost figures, "Revolutionary Biology" is a manifesto and educated layman's guide to this ongoing revolution.

Barash's purpose is to demystify the basic concepts of the genetic revolution and take the reader on a tour--accessible and authoritative--of the principles that underlie this fascinating turn in scientific thought. Much has been written about evolution, animals, and the animal and evolutionary origins of human behavior, yet only recently have biologists begun to appreciate these connections. The key concept is that genes--not species, not groups, and not even individuals--are the apple of evolution's eye. The result has been a major biological paradigm shift that is making itself felt in the social sciences as well. Barash explores the phenomenon of altruism both at the animal level, and the human level.

Barash draws not only on a wealth of biological evidence but on literature, philosophy, and the familiar details of everyday life to communicate the essentials of this increasingly influential approach to the study of the human species. Clearly and engagingly written, "Revolutionary Biology" will be fascinating reading for those seeking an entry into this new science.
