Book excerpt: The evolutionary history of life includes two primary components: phylogeny and timescale. Phylogeny refers to the branching order (relationships) of species or other taxa within a group and is crucial for understanding the inheritance of traits and for erecting classifications. However, a timescale is equally important because it provides a way to compare phylogeny directly with the evolution of other organisms and with planetary history such as geology, climate, extraterrestrial impacts, and other features. The Timetree of Life is the first reference book to synthesize the wealth of information relating to the temporal component of phylogenetic trees. In the past, biologists have relied exclusively upon the fossil record to infer an evolutionary timescale. However, recent revolutionary advances in molecular biology have made it possible to not only estimate the relationships of many groups of organisms, but also to estimate their times of divergence with molecular clocks. The routine estimation and utilization of these so-called 'time-trees' could add exciting new dimensions to biology including enhanced opportunities to integrate large molecular data sets with fossil and biogeographic evidence (and thereby foster greater communication between molecular and traditional systematists). They could help estimate not only ancestral character states but also evolutionary rates in numerous categories of organismal phenotype; establish more reliable associations between causal historical processes and biological outcomes; develop a universally standardized scheme for biological classifications; and generally promote novel avenues of thought in many arenas of comparative evolutionary biology. This authoritative reference work brings together, for the first time, experts on all major groups of organisms to assemble a timetree of life. The result is a comprehensive resource on evolutionary history which will be an indispensable reference for scientists, educators, and students in the life sciences, earth sciences, and molecular biology. For each major group of organism, a representative is illustrated and a timetree of families and higher taxonomic groups is shown. Basic aspects of the evolutionary history of the group, the fossil record, and competing hypotheses of relationships are discussed. Details of the divergence times are presented for each node in the timetree, and primary literature references are included. The book is complemented by an online database (www.timetree.net) which allows researchers to both deposit and retrieve data.

Download or read book The Tangled Tree written by David Quammen and published by Simon & Schuster. This book was released on 2019-08-06 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this New York Times bestseller and longlist nominee for the National Book Award, “our greatest living chronicler of the natural world” (The New York Times), David Quammen explains how recent discoveries in molecular biology affect our understanding of evolution and life’s history. In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field—the study of life’s diversity and relatedness at the molecular level—is horizontal gene transfer (HGT), or the movement of genes across species lines. It turns out that HGT has been widespread and important; we now know that roughly eight percent of the human genome arrived sideways by viral infection—a type of HGT. In The Tangled Tree, “the grandest tale in biology….David Quammen presents the science—and the scientists involved—with patience, candor, and flair” (Nature). We learn about the major players, such as Carl Woese, the most important little-known biologist of the twentieth century; Lynn Margulis, the notorious maverick whose wild ideas about “mosaic” creatures proved to be true; and Tsutomu Wantanabe, who discovered that the scourge of antibiotic-resistant bacteria is a direct result of horizontal gene transfer, bringing the deep study of genome histories to bear on a global crisis in public health. “David Quammen proves to be an immensely well-informed guide to a complex story” (The Wall Street Journal). In The Tangled Tree, he explains how molecular studies of evolution have brought startling recognitions about the tangled tree of life—including where we humans fit upon it. Thanks to new technologies, we now have the ability to alter even our genetic composition—through sideways insertions, as nature has long been doing. “The Tangled Tree is a source of wonder….Quammen has written a deep and daring intellectual adventure” (The Boston Globe).

Download or read book Squirrel Hill written by Mark Oppenheimer and published by Knopf. This book was released on 2021-10-05 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: A piercing portrait of the struggles and triumphs of one of America's renowned Jewish neighborhoods in the wake of unspeakable tragedy that highlights the hopes, fears, and tensions all Americans must confront on the road to healing. Squirrel Hill, Pittsburgh, is one of the oldest Jewish neighborhoods in the country, known for its tight-knit community and the profusion of multigenerational families. On October 27, 2018, a gunman killed eleven Jews who were worshipping at the Tree of Life synagogue in Squirrel Hill--the most deadly anti-Semitic attack in American history. Many neighborhoods would be understandably subsumed by despair and recrimination after such an event, but not this one. Mark Oppenheimer poignantly shifts the focus away from the criminal and his crime, and instead presents the historic, spirited community at the center of this heartbreak. He speaks with residents and nonresidents, Jews and gentiles, survivors and witnesses, teenagers and seniors, activists and historians. Together, these stories provide a kaleidoscopic and nuanced account of collective grief, love, support, and revival. But Oppenheimer also details the difficult dialogue and messy confrontations that Squirrel Hill had to face in the process of healing, and that are a necessary part of true growth and understanding in any community. He has reverently captured the vibrancy and caring that still characterize Squirrel Hill, and it is this phenomenal resilience that can provide inspiration to any place burdened with discrimination and hate.

Download or read book The Advent of PhyloCode written by Michel Laurin and published by CRC Press. This book was released on 2023-08-03 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nomenclature is an essential tool for storing and retrieving biological information. Yet traditional nomenclature poorly reflects evolutionary theory. Current biological nomenclature is one of the few fields promoting deliberately vague usage of technical terms. A new code based on evolutionary studies and phylogenetic results (the PhyloCode) will be a major milestone in biological nomenclature. Unfortunately, The PhyloCode and the companion volume are highly technical publications intended for practicing systematists. This book will reach a broader readership of those using nomenclature but who remain unaware of its theoretical foundations. Key Features Responds to the biodiversity crisis and the recent implementation of the PhyloCode Summarizes the spectacular progress of phylogenetics which makes it both increasingly easy and crucially important to define precisely taxon names Provides a 300-year historical perspective featuring high-profile characters, such as Linnaeus and Darwin Summarizes for a broad readership a widely scattered, highly technical and underappreciated scientific literature Documents the activities of the International Society for Phylogenetic Nomenclature, a scholarly society in which the author has played a prominent role

Download or read book Climate Change Ecology and Systematics written by Trevor R. Hodkinson and published by Cambridge University Press. This book was released on 2011-04-28 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change has shaped life in the past and will continue to do so in the future. Understanding the interactions between climate and biodiversity is a complex challenge to science. With contributions from 60 key researchers, this book examines the ongoing impact of climate change on the ecology and diversity of life on earth. It discusses the latest research within the fields of ecology and systematics, highlighting the increasing integration of their approaches and methods. Topics covered include the influence of climate change on evolutionary and ecological processes such as adaptation, migration, speciation and extinction, and the role of these processes in determining the diversity and biogeographic distribution of species and their populations. This book ultimately illustrates the necessity for global conservation actions to mitigate the effects of climate change in a world that is already undergoing a biodiversity crisis of unprecedented scale.

Download or read book Cosmosapiens written by John Hands and published by Abrams. This book was released on 2017-10-31 with total page 711 pages. Available in PDF, EPUB and Kindle. Book excerpt: “A critical overview of scientific orthodoxy in an attempt to answer the fundamental questions “what are we?” and “why are we here?” (Kirkus Reviews). Specialist scientific fields are developing at incredibly swift speeds, but what can they really tell us about how the universe began and how we as humans evolved to play such a dominant role on Earth? John Hands’s extraordinarily ambitious book merges scientific knowledge from multiple disciplines and evaluates without bias or preconception all the theories and evidence about the origin and evolution of matter, consciousness, and mankind. The result, a “pearl of dialectical reasoning” (Publishers Weekly, starred review), provides the most comprehensive account yet of current ideas such as cosmic inflation, dark energy, the selfish gene, and neurogenetic determinism. In the clearest possible prose, it differentiates the firmly established from the speculative and examines the claims of various fields to approach a unified theory of everything. In doing so it challenges the orthodox consensus in those branches of cosmology, biology, and neuroscience that have ossified into dogma. Its “shocking and invigorating” analysis (Daily Telegraph, A Best Science Book of 2015) reveals underlying patterns of cooperation, complexification, and convergence that lead to the unique emergence in humans of a self-reflective consciousness that enables us to determine our future evolution. This groundbreaking book is destined to become a classic of scientific thinking. Praise for Cosmosapiens “This is a truly exceptional piece of work.” —Tim Crane, Knightsbridge Professor of Philosophy, The University of Cambridge “A game-changer. In the tradition of Thomas Kuhn’s The Structure of Scientific Revolutions, this lucidly written, penetrating analysis challenges us to rethink many things we take for granted about ourselves, our society, and our universe. It will become a classic.” —Peter Dreier, E P Clapp Distinguished Professor of Politics, Occidental College “Hands is an astute observer of recent trends in scientific ideas bold enough to point out what he sees as sense and nonsense and intelligently explain why. Even in cases where one might disagree, the arguments are thought-provoking.” —Paul Steinhardt, Albert Einstein Professor in Science, Princeton University

Download or read book The Biophysics of Photosynthesis written by John Golbeck and published by Springer. This book was released on 2014-08-07 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume is intended as an introduction to the physical principles governing the main processes that occur in photosynthesis, with emphasis on the light reactions and electron transport chain. A unique feature of the photosynthetic apparatus is the fact that the molecular structures are known in detail for essentially all of its major components. The availability of this data has allowed their functions to be probed at a very fundamental level to discover the design principles that have guided evolution. Other volumes on photosynthesis have tended to focus on single components or on a specific set of biophysical techniques, and the authors’ goal is to provide new researchers with an introduction to the overall field of photosynthesis. The book is divided into sections, each dealing with one of the main physical processes in photosynthetic energy conversion. Each section has several chapters each describing the role that a basic physical property, such as charge or spin, plays in governing the process being discussed. The chapters proceed in an orderly fashion from a quantum mechanical description of early processes on an ultrafast timescale to a classical treatment of electron transfer and catalysis on a biochemical timescale culminating in evolutionary principles on a geological timescale.

Download or read book The Monkey s Voyage written by Alan de Queiroz and published by Basic Books. This book was released on 2014-01-07 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the world, closely related species are found on landmasses separated by wide stretches of ocean. What explains these far-flung distributions? Why are such species found where they are across the Earth? Since the discovery of plate tectonics, scientists have conjectured that plants and animals were scattered over the globe by riding pieces of ancient supercontinents as they broke up. In the past decade, however, that theory has foundered, as the genomic revolution has made reams of new data available. And the data has revealed an extraordinary, stranger-than-fiction story that has sparked a scientific upheaval. In The Monkey's Voyage, biologist Alan de Queiroz describes the radical new view of how fragmented distributions came into being: frogs and mammals rode on rafts and icebergs, tiny spiders drifted on storm winds, and plant seeds were carried in the plumage of sea-going birds to create the map of life we see today. In other words, these organisms were not simply constrained by continental fate; they were the makers of their own geographic destiny. And as de Queiroz shows, the effects of oceanic dispersal have been crucial in generating the diversity of life on Earth, from monkeys and guinea pigs in South America to beech trees and kiwi birds in New Zealand. By toppling the idea that the slow process of continental drift is the main force behind the odd distributions of organisms, this theory highlights the dynamic and unpredictable nature of the history of life. In the tradition of John McPhee's Basin and Range, The Monkey's Voyage is a beautifully told narrative that strikingly reveals the importance of contingency in history and the nature of scientific discovery.

Download or read book The Bare Bones written by Matthew F. Bonnan and published by Indiana University Press. This book was released on 2016-02-15 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Bonnan combines wit and passion with the sensibilities of a talented instructor in this encyclopedic tour of the vertebrate skeleton.” —Publishers Weekly What can we learn about the evolution of jaws from a pair of scissors? How does the flight of a tennis ball help explain how fish overcome drag? What do a spacesuit and a chicken egg have in common? Highlighting the fascinating twists and turns of evolution across more than 540 million years, paleobiologist Matthew Bonnan uses everyday objects to explain the emergence and adaptation of the vertebrate skeleton. What can camera lenses tell us about the eyes of marine reptiles? How does understanding what prevents a coffee mug from spilling help us understand the posture of dinosaurs? The answers to these and other intriguing questions illustrate how scientists have pieced together the history of vertebrates from their bare bones. With its engaging and informative text, plus more than 200 illustrative diagrams created by the author, The Bare Bones is an unconventional and reader-friendly introduction to the skeleton as an evolving machine. “No bones about it, a text like The Bare Bones was sorely needed in the popular literature of vertebrate paleontology. Matthew Bonnan’s tome on the evolution, form, and function of the vertebrate skeleton may seem daunting in size, but it is written in an enjoyable and readable fashion that will absolutely delight all sorts of readers from expert to soon-to-be-expert.” —Palaeontologia Electronica “A remarkably fun book to read . . . his conversational style and wit make this an unintimidating yet highly informative book that would work wonderfully in college courses.” —The Quarterly Review of Biology
