Haldane, Mayr, and Beanbag Genetics presents a summary of the
classic exchange between two great biologists - J.B.S. Haldane and
Ernst Mayr - regarding the value of the contributions of the
mathematical school represented by J.B.S. Haldane, R.A. Fisher and
S. Wright to the theory of evolution. Their pioneering
contributions from 1918 to the 1960s dominated and shaped the field
of population genetics, unique in the annals of science. In 1959,
Mayr questioned what he regarded as the beanbag genetic approach of
these pioneers to evolutionary theory, "an input or output of
genes, as the adding of certain beans to a beanbag and the
withdrawing of others." In 1964, Mayr's contention was refuted by
Haldane in a remarkably witty, vigorous and pungent essay, "A
defense of beanbag genetics" which compared the mathematical theory
to a scaffolding within which a reasonably secure theory
expressible in words may be built up. Correspondence between
Haldane and Mayr is included.
Polls show that 45% of the American public believes that humans
were created about 10,000 years ago and that evolution is a
fictitious myth. Another 25% believes that changes in the natural
world are directed by a supernatural being with a particular goal
in mind. This thinking clashes head on with scientific findings
from the past 150 years, and there is a dearth of public critical
thinking about the natural world within a scientific framework.
Ostracoda (Crustacea) are potentially excellent model organisms for evolutionary studies, because they combine an extensive fossil record with a wide recent distribution and therefore allow studies on both patterns and processes leading to extant diversity. The main scientific domains contributing theories, concepts, and data to evolutionary biology are morphology (including ontogeny), palaeontology, genetics, and ecology, and to all of these aspects ostracods can contribute. This is clearly illustrated by the fifteen papers presented under Theme 3 of the 13th International Symposium on Ostracoda (Chatham, UK) in 1997 which are grouped in the present proceedings, one of three volumes resulting from this meeting. The contributions deal with the evolution of both extant and fossil forms (including most of the Phanaerozoic), ecology of both marine and freshwater taxa, and (developmental) morphology of both soft parts and valves. Although the canvas is wide, each paper clearly shows how studies on Ostracoda can be relevant to general theory on evolutionary biology and ecology.
ONE OF AMAZON'S TOP 100 BOOKS OF 2014 Neanderthal Man tells the story of geneticist Svante Paabo's mission to answer this question: what can we learn from the genomes of our closest evolutionary relatives? Beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in the sequencing of the Neanderthal genome in 2010, Neanderthal Man describes the events, intrigues, failures, and triumphs of these scientifically rich years through the lens of the pioneer and inventor of the field of ancient DNA. We learn that Neanderthal genes offer a unique window into the lives of our hominid relatives and may hold the key to unlocking the mystery of why humans survived while Neanderthals went extinct. Paabo's findings have not only redrawn our family tree, but recast the fundamentals of human history,the biological beginnings of fully modern Homo sapiens , the direct ancestors of all people alive today.
Dr. G nti has introduced Chemoton Theory to explain the origin of life. Theoretical Foundations of Fluid Machineries is a discussion of the theoretical foundations of fluid automata. It introduces quantitative methods - cycle stoichiometry and stoichiokinetics - in order to describe fluid automata with the methods of algebra, as well as their construction, starting from elementary chemical reactions up to the complex, program-directed, proliferating fluid automata, the chemotons. Chemoton Theory outlines the development of a theoretical biology, based on exact quantitative considerations and the consequences of its application on biotechnology and on the artificial synthesis of living systems.
Seymour W. Itzkoff is one of the world's leading intelligence researchers. His exciting new book Our Unfinished Biological Revolution offers a bold and highly original new study on the evolution of human intelligence from the origin of life to our times. With the help of evolutionary theory, Itzkoff explains the nature of human intelligence as we know it today. Most importantly, it demonstrates that evolution led to the rise of what intelligence researchers call the general intelligence factor: the human ability to plan ahead and solve problems for which natural selection did not prepare us. The book also argues that humans vary in intelligence (as with all traits shaped by Darwinian evolution), and hence in their propensity to think abstractly and anticipate long-term consequences of their actions. Our Unfinished Biological Revolution explores the social implications of these two factors as they unfold in modern technological societies, in which intelligence plays an increasingly important role. Finally, the book argues that human intelligence may offer our best hope in solving the daunting problems of the present era?including population growth, the exhaustion of natural resources, and the rise of simplistic and devastating ideologies.
Does there exist, deep within the earth's crust, a second biosphere-- composed of very primitive, thermophilic (heat-loving) bacteria, and containing more living matter than the entire surface? This idea, first proposed by the author in the early 1980s, is now supported by a growing body of evidence. The implications are astonishing: is the deep biosphere where life originated? Can Mars and other seemingly dead planets contain deep biospheres? Is there yet another--deeper, hotter--biosphere within the earth, based on silicon instead of carbon? This is the first book to explore this very controversial, intriguing theory.
Written for non-experts, this volume introduces the mechanisms that underlie reticulate evolution. Chapters are either accompanied with glossaries that explain new terminology or timelines that position pioneering scholars and their major discoveries in their historical contexts. The contributing authors outline the history and original context of discovery of symbiosis, symbiogenesis, lateral gene transfer, hybridization or divergence with gene flow and infectious heredity. By applying key insights from the areas of molecular (phylo)genetics, microbiology, virology, ecology, systematics, immunology, epidemiology and computational science, they demonstrate how reticulate evolution impacts successful survival, fitness and speciation. Reticulate evolution brings forth a challenge to the standard Neo-Darwinian framework, which defines life as the outcome of bifurcation and ramification patterns brought forth by the vertical mechanism of natural selection. Reticulate evolution puts forward a pattern in the tree of life that is characterized by horizontal mergings and lineage crossings induced by symbiosis, symbiogenesis, lateral gene transfer, hybridization or divergence with gene flow and infective heredity, making the "tree of life" look more like a "web of life." On an epistemological level, the various means by which hereditary material can be transferred horizontally challenges our classic notions of units and levels of evolution, fitness, modes of transmission, linearity, communities and biological individuality. The case studies presented examine topics including the origin of the eukaryotic cell and its organelles through symbiogenesis; the origin of algae through primary and secondary symbiosis and dinoflagellates through tertiary symbiosis; the superorganism and holobiont as units of evolution; how endosymbiosis induces speciation in multicellular life forms; transferrable and non-transferrable plasmids and how they symbiotically interact with their host; the means by which pro- and eukaryotic organisms transfer genes laterally (bacterial transformation, transduction and conjugation as well as transposons and other mobile genetic elements); hybridization and divergence with gene flow in sexually-reproducing individuals; current (human) microbiome and viriome studies that impact our knowledge concerning the evolution of organismal health and acquired immunity; and how symbiosis and symbiogenesis can be modelled in computational evolution.
This set of lecture notes gives a first coherent account on a novel aspect of the living world that can be called biological information. The book presents both a pedagogical and state-of-the art roadmap of this rapidly evolving field and covers the whole range from information which is encoded in the molecular genetic code to the description of large-scale evolution of complex species networks. The book will prove useful for all those who work at the interface of biology, physics and information science.
This book is divided in two parts, the first of which shows how, beyond paleontology and systematics, macroevolutionary theories apply key insights from ecology and biogeography, developmental biology, biophysics, molecular phylogenetics and even the sociocultural sciences to explain evolution in deep time. In the second part, the phenomenon of macroevolution is examined with the help of real life-history case studies on the evolution of eukaryotic sex, the formation of anatomical form and body-plans, extinction and speciation events of marine invertebrates, hominin evolution and species conservation ethics. The book brings together leading experts, who explain pivotal concepts such as Punctuated Equilibria, Stasis, Developmental Constraints, Adaptive Radiations, Habitat Tracking, Turnovers, (Mass) Extinctions, Species Sorting, Major Transitions, Trends and Hierarchies - key premises that allow macroevolutionary epistemic frameworks to transcend microevolutionary theories that focus on genetic variation, selection, migration and fitness. Along the way, the contributing authors review ongoing debates and current scientific challenges; detail new and fascinating scientific tools and techniques that allow us to cross the classic borders between disciplines; demonstrate how their theories make it possible to extend the Modern Synthesis; present guidelines on how the macroevolutionary field could be further developed; and provide a rich view of just how it was that life evolved across time and space. In short, this book is a must-read for active scholars and because the technical aspects are fully explained, it is also accessible for non-specialists. Understanding evolution requires a solid grasp of above-population phenomena. Species are real biological individuals and abiotic factors impact the future course of evolution. Beyond observation, when the explanation of macroevolution is the goal, we need both evidence and theory that enable us to explain and interpret how life evolves at the grand scale.
Sex Differences serves as an advanced text for courses in
evolutionary and human biology, psychology, and sexuality and
gender studies. It also serves as a reference source for academic
professionals in these disciplines. The book covers the evolution
of sex and sex differences, and sex differences and sexual
strategies in non-human and human animals. The final chapter
addresses issues of sex and gender in interpersonal relationships,
organizations and politics. Diagrams, graphs, charts, and tables
illustrate key concepts; cartoons and photos provide visual breaks
and an element of humor.
This book is about what science frequently dodges or even denies:
subjective life as experienced by animals as well as humans. Mixing
what is known from science with some novel ideas, science writer
William Libaw provides a provocative and stimulating thesis on the
origins and evolution of consciousness.
This book focuses on how climatic change during the last fifteen million years - especially the last three million - has affected human evolution and other evolutionary events. Leading evolutionists and physical geologists from all over the worldauthorities on such subjects as paleoceanography, palynology, mammalian paleontology, and paleoanthropology - address the relationship between climatic and biotic evolution, presenting and integrating the most up-to-date research in their fields. Among the subjects discussed are: global and regional climatic changes; tectonism and its effects on climate; the evolution of biomes and mammals; the ways climate might have influenced the origins of hominid species; and the evolution of hominid morphologies and behaviors. The book draws on the comparatively rich data base of the Late Neogene and includes many new data sets and hypotheses on paleoclimatic changes and on floral and mammalian evolution.
Biological systems are very special substrates for engineering-uniquely the products of evolution, they are easily redesigned by similar approaches. A simple algorithm of iterative cycles of diversification and selection, evolution works at all scales, from single molecules to whole ecosystems. In the little more than a decade since the first reported applications of evolutionary design to enzyme engineering, directed evolution has matured to the point where it now represents the centerpiece of industrial biocatalyst development and is being practiced by thousands of academic and industrial scientists in com- nies and universities around the world. The appeal of directed evolution is easy to understand: it is conceptually straightforward, it can be practiced without any special instrumentation and, most important, it frequently yields useful solutions, many of which are totally unanticipated. Directed evolution has r- dered protein engineering readily accessible to a broad audience of scientists and engineers who wish to tailor a myriad of protein properties, including th- mal and solvent stability, enzyme selectivity, specific activity, protease s- ceptibility, allosteric control of protein function, ligand binding, transcriptional activation, and solubility. Furthermore, the range of applications has expanded to the engineering of more complex functions such as those performed by m- tiple proteins acting in concert (in biosynthetic pathways) or as part of mac- molecular complexes and biological networks.
The diversity of social behavior among birds and primates is surpassed only by members of the Hymenopteran insects, including bees, ants, and the genus Polistes, or paper-wasps. This volume combines incisive reviews and new, unpublished data in studies of paper-wasps, a large and varied group whose life patterns are often studied by biologists interested in social evolution. While this research is significant to the natural history of paper-wasps, it also applies to topics of general interest such as the evolution of cooperation, social parasitism, kin recognition, and the division of labor.
Rough-and-tumble play provided one of the paradigmatic examples of the appli- tion of ethological methods, back in the 1970's. Since then, a modest number of - searchers have developed our knowledge of this kind of activity, using a variety of methods, and addressing some quite fundamental questions about age changes, sex diff- ences, nature and function of behaviour. In this chapter I will review work on this topic, mentioning particularly the interest in comparing results from different informants and different methods of investigation. Briefly, rough-and-tumble play (or R&T for short) refers to a cluster of behaviours whose core is rough but playful wrestling and tumbling on the ground; and whose general characteristic is that the behaviours seem to be agonistic but in a non-serious, playful c- text. The varieties of R&T, and the detailed differences between rough-and-tumble play and real fighting, will be discussed later. 2. A BRIEF HISTORY OF RESEARCH ON R&T In his pioneering work on human play, Groos (1901) described many kinds of rough-and-tumble play. However, R&T was virtually an ignored topic from then until the late 1960's. There was, of course, a flowering of observational research on children in the 1920s and 1930s, especially in North America; but this research had a strong practical o- entation, and lacked the cross-species perspective and evolutionary orientation present in Groos' work.
The New York Times bestselling author of Darwin’s Doubt, Stephen Meyer, presents groundbreaking scientific evidence of the existence of God, based on breakthroughs in physics, cosmology, and biology. Beginning in the late 19th century, many intellectuals began to insist that scientific knowledge conflicts with traditional theistic belief—that science and belief in God are “at war.” Philosopher of science Stephen Meyer challenges this view by examining three scientific discoveries with decidedly theistic implications. Building on the case for the intelligent design of life that he developed in Signature in the Cell and Darwin’s Doubt, Meyer demonstrates how discoveries in cosmology and physics coupled with those in biology help to establish the identity of the designing intelligence behind life and the universe. Meyer argues that theism—with its affirmation of a transcendent, intelligent and active creator—best explains the evidence we have concerning biological and cosmological origins. Previously Meyer refrained from attempting to answer questions about “who” might have designed life. Now he provides an evidence-based answer to perhaps the ultimate mystery of the universe. In so doing, he reveals a stunning conclusion: the data support not just the existence of an intelligent designer of some kind—but the existence of a personal God.
Most organisms and populations have to cope with hostile environments, threatening their existence. Their ability to respond phenotypically and genetically to these challenges and to evolve adaptive mechanisms is, therefore, crucial. The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems. Scientists, applying different approaches spanning from the molecular and the protein level to individuals, populations and ecosystems, explore how organisms adapt to extreme environments, how stress changes genetic structure and affects life histories, how organisms cope with thermal stress through acclimation, and how environmental and genetic stress induce fluctuating asymmetry, shape selection pressure and cause extinction of populations. Finally, it discusses the role of stress in evolutionary change, from stress induced mutations and selection to speciation and evolution at the geological time scale. The book contains reviews and novel scientific results on the subject. It will be of interest to both researchers and graduate students and may serve as a text for graduate courses.
The volumes in this set, originally published between 1913 and 1997, draw together research by leading academics in the area of evolution and provide a rigorous examination of related key issues. The collection examines evolution from a broad range of disciplines, from the anthropological development of modern society, to the scientific examinations of cellular and genetic evolution. The collection includes volumes across the disciplines of biology, natural history, anthropology, sociology and religion. The 15 books that comprise this collection include rigorous examinations into the psychological evolution of the brain, philosophical and theological examinations of evolution, analysis of genetic and cellular evolution, discussions of Darwinian theory, the affect of survival of the fittest from both genetic and political standpoints and examinations into the affinity between man and ape. This collection brings back into print a collection of insightful and detailed books on the diverse subject of evolution and will be a must have resource for academics and students, not only of biology and anthropology, but of history, psychology and religion.
Given the rapidly developing area of evolutionary medicine and public health, The Arc of Life examines ways in which research conducted by biological anthropologists can enrich our understanding of variation in human health outcomes. The book aims not only to showcase the perspective that biological anthropologists bring to the burgeoning field of evolutionary medicine, but to underscore the context of human life history -- especially the concept of evolutionary trade-offs and the ensuing biological processes that can affect health status over the life course. This dual emphasis on life history theory and life cycle biology will make for a valuable and unique, yet complementary, addition to books already available on the subject of evolution and health. The book consolidates diverse lines of research within the field of biological anthropology, stimulates new directions for future research, and facilitates communication between subdisciplines of human biology operating at the forefront of evolutionary medicine.

Researchers in the field of ecological genomics aim to determine how a genome or a population of genomes interacts with its environment across ecological and evolutionary timescales. Ecological genomics is trans-disciplinary by nature. Ecologists have turned to genomics to be able to elucidate the mechanistic bases of the biodiversity their research tries to understand. Genomicists have turned to ecology in order to better explain the functional cellular and molecular variation they observed in their model organisms. We provide an advanced-level book that covers this recent research and proposes future development for this field. A synthesis of the field of ecological genomics emerges from this volume."Ecological Genomics"covers a wide array of organisms (microbes, plants and animals) in order to be able to identify central concepts that motivate and derive from recent investigations in different branches of the tree of life. "Ecological Genomics"covers 3 fields of research that have most benefited from the recent technological and conceptual developments in the field of ecological genomics: the study of life-history evolution and its impact of genome architectures; the study of the genomic bases of phenotypic plasticity and the study of the genomic bases of adaptation and speciation.

In The Descent of Man, Charles Darwin (1809-1882) focuses special attention on the origin and history of our own species, a subject he had avoided in previous writings on evolution. He claims that the human animal is closest in ancestry to the two African pongids or anthropoid apes (chimpanzees and gorillas). Further, Darwin held that our species and these two pongids differ merely in degree rather than in kind -- a controversial view that contradicted religious doctrine. The Descent of Man (1871) looks at the emergence of humans in terms of primate evolution. Darwin presents a strictly mechanistic and materialistic interpretation of our species that is free from superstition and spiritualism. |
