Book Description
To document the world's diversity of species and reconstruct the tree of life we need to undertake some simple but mountainous tasks. Most importantly, we need to tackle species rich groups. We need to collect, name, and classify them, and then position them on the tree of life. We need to do this systematically across all groups of organisms and b

Book Description
The Great Tree of Life is a concise, approachable treatment that surveys the concept of the Tree of Life, including chapters on its historical introduction and cultural connection. The Tree of Life is a metaphor used to describe the relationships between organisms, both living and extinct. It has been widely recognized that the relationship between the roughly 10 million species on earth drives the ecological system. This work covers options on how to build the tree, demonstrating its utility in drug discovery, curing disease, crop improvement, conservation biology and ecology, along with tactics on how to respond to the challenges of climate change. This book is a key aid on the improvement of our understanding of the relationships between species, the increasing and essential awareness of biodiversity, and the power of employing modern biology to build the tree of life. - Provides a single reference describing the properties, history and utility of The Tree of Life - Introduces phylogenetics and its applications in an approachable manner - Written by experts on the Tree of Life - Includes an online companion site containing various original videos to enhance the reader's understanding and experience

Book Description
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).

Book Description
Evolution is a complex process, acting at multiple scales, from DNA sequences and proteins to populations of species. Understanding and reconstructing evolution is of major importance in numerous subfields of biology. For example, phylogenetics and sequence evolution is central to comparative genomics, attempts to decipher genomes, and molecular epidemiology. Phylogenetics is also the focal point of large-scale international biodiversity assessment initiatives such as the 'Tree ofLife' project, which aims to build the evolutionary tree for all extant species.Since the pioneering work in phylogenetics in the 1960s, models have become increasingly sophisticated to account for the inherent complexity of evolution. They rely heavily on mathematics and aim at modelling and analyzing biological phenomena such as horizontal gene transfer, heterogeneity of mutation, and speciation and extinction processes. This book presents these recent models, their biological relevance, their mathematical basis, their properties, and the algorithms to infer them fromdata. A number of subfields from mathematics and computer science are involved: combinatorics, graph theory, stringology, probabilistic and Markov models, information theory, statistical inference, Monte Carlo methods, continuous and discrete algorithmics.This book arises from the Mathematics of Evolution & Phylogenetics meeting at the Mathematical Institute Henri Poincaré, Paris, in June 2005 and is based on the outstanding state-of-the-art reports presented by the conference speakers. Ten chapters - based around five themes - provide a detailed overview of key topics, from the underlying concepts to the latest results, some of which are at the forefront of current research.

Book Description
In December 2004, the National Academy of Sciences sponsored a colloquium on "Systematics and the Origin of Species" to celebrate Ernst Mayr's 100th anniversary and to explore current knowledge concerning the origin of species. In 1942, Ernst Mayr, one of the twentieth century's greatest scientists, published Systematics and the Origin of Species, a seminal book of the modern theory of evolution, where he advanced the significance of population variation in the understanding of evolutionary process and the origin of new species. Mayr formulated the transition from Linnaeus's static species concept to the dynamic species concept of the modern theory of evolution and emphasized the species as a community of populations, the role of reproductive isolation, and the ecological interactions between species. In addition to a preceding essay by Edward O. Wilson, this book includes the 16 papers presented by distinguished evolutionists at the colloquium. The papers are organized into sections covering the origins of species barriers, the processes of species divergence, the nature of species, the meaning of "species," and genomic approaches for understanding diversity and speciation.

Book Description
This is the first book on "phylogenetic supertrees", a recent, but controversial development for inferring evolutionary trees. Rather than analyze the combined primary character data directly, supertree construction proceeds by combining the tree topologies derived from those data. This difference in strategy has allowed for the exciting possibility of larger, more complete phylogenies than are otherwise currently possible, with the potential to revolutionize evolutionarily-based research. This book provides a comprehensive look at supertrees, ranging from the methods used to build supertrees to the significance of supertrees to bioinformatic and biological research. Reviews of many the major supertree methods are provided and four new techniques, including a Bayesian implementation of supertrees, are described for the first time. The far-reaching impact of supertrees on biological research is highlighted both in general terms and through specific examples from diverse clades such as flowering plants, even-toed ungulates, and primates. The book also critically examines the many outstanding challenges and problem areas for this relatively new field, showing the way for supertree construction in the age of genomics. Interdisciplinary contributions from the majority of the leading authorities on supertree construction in all areas of the bioinformatic community (biology, computer sciences, and mathematics) will ensure that this book is a valuable reference with wide appeal to anyone interested in phylogenetic inference.

Book Description
A Fresh Look at Taxonomy The most fundamental of all biological sciences, taxonomy underpins any long term strategies for reconstructing the great tree of life or salvaging as much biodiversity as possible. Initiatives reinventing taxonomy for the Internet age are leading to a resurgence in this once declining discipline. In this volume we witness the emergence of cybertaxonomy, a convergence of descriptive taxonomy with information science and computer engineering. Featuring a new paradigm of international teamwork, The New Taxonomy presents a roadmap for confronting the biodiversity crisis. Some have seen the confusion of pattern and process that followed Huxley's 1940 The New Systematics as the beginning of decline for support of taxonomy. In this answer to Huxley, contemporary taxonomists reclaim the unique mission, goals and importance of taxonomy as an independent science.

Book Description
The birth of bacterial genomics since the mid-1990s brought withit several conceptual modifications and wholly new controversies. Working beyond the scope of the neo-Darwinian evolutionary synthesis, a group of leading microbial evolutionists addresses the following and related issues, often with markedly varied viewpoints: · Did the eukaryotic nucleus, cytoskeleton and cilia also orginate from symbiosis? · Do the current scenarios about he origin of mitochondria and plastids require revision? · What is the extent of lateral gene transfer (between "species") among bacteria? · Does the rDNA phylogenetic tree still stand in the age of genomics? · Is the course of the first 3 billion years of evolution even knowable?

Book Description
Without domestication, civilization as we know it would not exist. Since that fateful day when the first wolf decided to stay close to human hunters, humans and their various animal companions have thrived far beyond nearly all wild species on earth. Tameness is the key trait in the domestication of cats, dogs, horses, cows, and other mammals, from rats to reindeer. Surprisingly, with selection for tameness comes a suite of seemingly unrelated alterations, including floppy ears, skeletal and coloration changes, and sex differences. It’s a package deal known as the domestication syndrome, elements of which are also found in humans. Our highly social nature—one of the keys to our evolutionary success—is due to our own tameness. In Domesticated, Richard C. Francis weaves history and anthropology with cutting-edge ideas in genomics and evo devo to tell the story of how we domesticated the world, and ourselves in the process.
