Approximately 99.9% of vertebrate species reproduce sexually. The exceptional 0.1% reproduce via asexual or clonal means, which vary wildly and are fascinating in their own right. In this book, John C. Avise describes the genetics, ecology, natural history, and evolution of the world's approximately 100 species of vertebrate animal that routinely display one form or another of clonal or quasi-clonal reproduction. Approximately 99.9% of vertebrate species reproduce sexually. The exceptional 0.1% reproduce via asexual or clonal means, which vary wildly and are fascinating in their own right. In this book, John C. Avise describes the genetics, ecology, natural history, and evolution of the world's approximately 100 species of vertebrate animal that routinely display one form or another of clonal or quasi-clonal reproduction. By considering the many facets of sexual abstinence and clonal reproduction in vertebrate animals, Avise sheds new light on the biological meaning and ramifications of standard sexuality.
Conceptual Breakthroughs in the Evolutionary Biology of Aging continues the innovative Conceptual Breakthroughs series by providing a comprehensive outline of the major breakthroughs that built the evolutionary biology of aging as a leading scientific field. Following the evolutionary study of aging from its humble origins to the present, the book's chapters treat the fieldâs breakthroughs one at a time. Users will find a concise and accessible analysis of the science of aging viewed through an evolutionary lens. Building upon widely-cited studies conducted by author Michael Rose, this book covers 30 subsequent years of growth and development within the field. The book highlights key publications for those who are not experts in the field, providing an important resource for researchers. Given the prevailing interest in changing the aging process dramatically, it is a powerful tool for readers who have a vested interest in understanding its causes and future control measures.
An introductory tour into the stranger-than-fiction world of genetic engineering, a scientific realm inhabited by eager researchers intent upon fashioning a prodigious medley of genetically modified (GM) organisms to serve human needs.
Hundreds of animal species provide the cast of characters for these newly composed bio-limericks, arranged into 17 chapters by taxonomic group (such as Birds, Fishes, Insects) or biological subject (such as Ecology, Genetics, and Anthropology). Sometimes multiple verses on one organism or topic provide an extended story-line across successive poems. In addition, several stylistic vignettes recur throughout the book, such as: (a) "On the Farm", which ranges from barnyards to fish farms to oyster farms; and (b) "Let's Play Jeopardy", where the reader guesses an animal from poetic clues the author provides. Each little jingle can be read as a stand-alone offering a quick chuckle or biological insight. But watch out-these poetic tidbits can be as addictive as popcorn, such that some readers will feel compelled to consume each chapter and indeed the entire book at one sitting! Covering nearly every creature that any amateur or professional biologist has ever heard of, these pun-filled limericks provide humorous insight into each critter or its peculiar habits, in a sharply witty and cutely informative way.
"Conceptual Breakthroughs in Evolutionary Genetics" is a pithy, lively book occupying a special niche-the conceptual history of evolutionary genetics- not inhabited by any other available treatment. Written by a world-leading authority in evolutionary genetics, this work encapsulates and ranks 70 of the most significant paradigm shifts in evolutionary biology and genetics during the century-and-a-half since Darwin and Mendel. The science of evolutionary genetics is central to all of biology, but many students and other practitioners have little knowledge of its historical roots and conceptual developments. This book fills that knowledge gap in a thought-provoking and readable format. This fascinating chronological journey along the many conceptual
pathways to our modern understanding of evolutionary and genetic
principles is a wonderful springboard for discussions in
undergraduate or graduate seminars in evolutionary biology and
genetics. But more than that, anyone interested in the history and
philosophy of science will find much of value between its
covers.
Humanity's physical design flaws have long been apparent--we get hemorrhoids and impacted wisdom teeth, for instance--but do the imperfections extend down to the level of our genes? Inside the Human Genome is the first book to examine the philosophical question of why, from the perspectives of biochemistry and molecular genetics, flaws exist in the biological world. Distinguished evolutionary geneticist John Avise offers a panoramic yet penetrating exploration of the many gross deficiencies in human DNA--ranging from mutational defects to built-in design faults--while at the same time offering a comprehensive treatment of recent findings about the human genome. The author shows that the overwhelming scientific evidence for genomic imperfection provides a compelling counterargument to intelligent design. He also develops a case that theologians should welcome rather than disavow these discoveries. The evolutionary sciences can help mainstream religions escape the shackles of Intelligent Design, and thereby return religion to its rightful realm--not as the secular interpreter of the biological minutiae of our physical existence, but rather as a respectable philosophical counselor on grander matters of ultimate concern.
This visually appealing book recounts the history of molecular ecology and evolution as seen through the personal lens of one of its most prolific practitioners, who has studied a panorama of creatures ranging from corals, sponges, and other invertebrates to a wide variety of vertebrate animals including numerous birds, mammals, herps, and fishes. The sketches are of two types: evocative drawings of the animals themselves, and more than 230 written abstracts summarizing the author's eclectic research on ecological-genetic topics spanning the microevolutionary to macroevolutionary. With the abstracts arranged by organismal group and placed in chronological order, the chapters in this book lead readers on a fascinating historical journey into the realm of molecular genetics as applied across the past four decades to intriguing questions in ecology, evolution, animal behavior, and natural history.
Award-winning geneticist John C. Avise guides this delightful
voyage around the planet in search of answers to nature's
mysteries. He demonstrates how scientists directly examine DNA to
address long-standing questions about wild animals, plants, and
microbes. Through dozens of stories that span the world, nature
emerges as a realm where truth can be far stranger than fiction.
From a 100-ton mushroom to egg-swapping birds, extinct ground
sloths to microbes inside our bodies, Avise examines a cornucopia
of natural-history topics and explains how today's modern genetic
techniques offer novel insights.
Phylogeography is a discipline concerned with various relationships between gene genealogies--phylogenetics--and geography. The word "phylogeography" was coined in 1987, and since then the scientific literature has reflected an exploding interest in the topic. Yet, to date, no book-length treatment of this emerging field has appeared. "Phylogeography: The History and Formation of Species" fills that gap. The study of phylogeography grew out of the observation that mitochondrial DNA lineages in natural populations often display distinct geographic orientations. In recent years, the field has expanded to include assessments of nuclear as well as cytoplasmic genomes and the relationships among gene trees, population demography, and organismal history, often formalized as coalescent theory. Phylogeography has connections to molecular evolutionary genetics, natural history, population biology, paleontology, historical geography, and speciation analysis. "Phylogeography" captures the conceptual and empirical richness of the field, and also the sense of genuine innovation that phylogeographic perspectives have brought to evolutionary studies. This book will be essential reading for graduate students and professionals in evolutionary biology and ecology as well as for anyone interested in the emergence of this new and integrative discipline.
Reconstructing phylogenetic trees from DNA sequences has become a popular exercise in many branches of biology, and here the well-known geneticist John Avise explains why. Molecular phylogenies provide a genealogical backdrop for interpreting the evolutionary histories of many other types of biological traits (anatomical, behavioral, ecological, physiological, biochemical and even geographical). Guiding readers on a natural history tour along dozens of evolutionary pathways, the author describes how creatures ranging from microbes to elephants came to possess their current phenotypes. Essential reading for college students, professional biologists and anyone interested in natural history and biodiversity, this book is packed with fascinating examples of evolutionary puzzles from across the animal kingdom; how the toucan got its enormous bill, how reptiles grow back lost limbs and why Arctic fish don't freeze.
They mastermind our lives, shaping our features, our health, and our behavior, even in the sacrosanct realms of love and sex, religion, aging, and death. Yet we are the ones who house, perpetuate, and give the promise of immortality to these biological agents, our genetic gods. The link between genes and gods is hardly arbitrary, as the distinguished evolutionary geneticist John Avise reveals in this compelling book. In clear, straightforward terms, Avise reviews recent discoveries in molecular biology, evolutionary genetics, and human genetic engineering, and discusses the relevance of these findings to issues of ultimate concern traditionally reserved for mythology, theology, and religious faith. The book explains how the genetic gods figure in our development--not just our metabolism and physiology, but even our emotional disposition, personality, ethical leanings, and, indeed, religiosity. Yet genes are physical rather than metaphysical entities. Having arisen via an amoral evolutionary process--natural selection--genes have no consciousness, no sentient code of conduct, no reflective concern about the consequences of their actions. It is Avise's contention that current genetic knowledge can inform our attempts to answer typically religious questions--about origins, fate, and meaning. The Genetic Gods challenges us to make the necessary connection between what we know, what we believe, and what we embody.
John Avise is one of the most distinguished evolutionary biologists of our time. His groundbreaking work with mitochondrial DNA created the entire discipline of phylogeography and his work on the Pleistocene refugia hypothesis redirected scientific thinking about patterns of distribution. Spanning a remarkable thirty-five-year career, the essays gathered here were rewritten from his previously published articles and represent the first single-volume collection of Avise's work. Moving through various questions in evolutionary biology, these eclectic essays reveal Avise's unique perspectives on major topics in the field. From how to define a species to the folly of faulty applications of cladistics to connections between conservation and evolutionary biology, On Evolution takes the reader on a personal journey into the mind of one of the world's leading evolutionists.
