Acquiring Genomes

Acquiring Genomes PDF Author: Lynn Margulis
Publisher: Basic Books
ISBN: 0786722606
Category : Science
Languages : en
Pages : 262

Book Description
In this groundbreaking book, Lynn Margulis and Dorion Sagan present an answer to one of the enduring mysteries of evolution -- the source of inherited variation that gives rise to new species. Random genetic mutation, long believed to be the main source of variation, is only a marginal factor. As the authors demonstrate in this book, the more important source of speciation, by far, is the acquisition of new genomes by symbiotic merger. The result of thirty years of delving into a vast, mostly arcane literature, this is the first book to go beyond -- and reveal the severe limitations of -- the "Modern Synthesis" that has dominated evolutionary biology for almost three generations. Lynn Margulis, whom E. O. Wilson called "one of the most successful synthetic thinkers in modern biology," and her co-author Dorion Sagan have written a comprehensive and scientifically supported presentation of a theory that directly challenges the assumptions we hold about the variety of the living world.

Book Description
How do species originate? This groundbreaking book presents an answer to the one enduring mystery of evolution that Darwin never solved: the source of the inherited variation that gives rise to new species. Random mutation, claimed to be the main source of genetic variation, is of only limited importance. Much more significant is the acquisition & integration of new genomes by symbiotic merger. The result of 30 years of delving into a vast arcane literature, this is the first book to reveal the extent of the dogmatic thinking that has dominated evolutionary biology since the early 20th cent. Presents a comprehensive & scientifically accurate theory that directly challenges popular assumptions about revolution & the diversity in the living world. Illustrations.

Symbiotic Planet

Symbiotic Planet PDF Author: Lynn Margulis
Publisher: Basic Books
ISBN: 078672448X
Category : Science
Languages : en
Pages : 158

Book Description
Although Charles Darwin's theory of evolution laid the foundations of modern biology, it did not tell the whole story. Most remarkably, The Origin of Species said very little about, of all things, the origins of species. Darwin and his modern successors have shown very convincingly how inherited variations are naturally selected, but they leave unanswered how variant organisms come to be in the first place. In Symbiotic Planet, renowned scientist Lynn Margulis shows that symbiosis, which simply means members of different species living in physical contact with each other, is crucial to the origins of evolutionary novelty. Ranging from bacteria, the smallest kinds of life, to the largest -- the living Earth itself -- Margulis explains the symbiotic origins of many of evolution's most important innovations. The very cells we're made of started as symbiotic unions of different kinds of bacteria. Sex -- and its inevitable corollary, death -- arose when failed attempts at cannibalism resulted in seasonally repeated mergers of some of our tiniest ancestors. Dry land became forested only after symbioses of algae and fungi evolved into plants. Since all living things are bathed by the same waters and atmosphere, all the inhabitants of Earth belong to a symbiotic union. Gaia, the finely tuned largest ecosystem of the Earth's surface, is just symbiosis as seen from space. Along the way, Margulis describes her initiation into the world of science and the early steps in the present revolution in evolutionary biology; the importance of species classification for how we think about the living world; and the way "academic apartheid" can block scientific advancement. Written with enthusiasm and authority, this is a book that could change the way you view our living Earth.

Genomes and What to Make of Them

Genomes and What to Make of Them PDF Author: Barry Barnes
Publisher: University of Chicago Press
ISBN: 0226172961
Category : Science
Languages : en
Pages : 282

Book Description
The announcement in 2003 that the Human Genome Project had completed its map of the entire human genome was heralded as a stunning scientific breakthrough: our first full picture of the basic building blocks of human life. Since then, boasts about the benefits—and warnings of the dangers—of genomics have remained front-page news, with everyone agreeing that genomics has the potential to radically alter life as we know it. For the nonscientist, the claims and counterclaims are dizzying—what does it really mean to understand the genome? Barry Barnes and John Dupré offer an answer to that question and much more in Genomes and What to Make of Them, a clear and lively account of the genomic revolution and its promise. The book opens with a brief history of the science of genetics and genomics, from Mendel to Watson and Crick and all the way up to Craig Venter; from there the authors delve into the use of genomics in determining evolutionary paths—and what it can tell us, for example, about how far we really have come from our ape ancestors. Barnes and Dupré then consider both the power and risks of genetics, from the economic potential of plant genomes to overblown claims that certain human genes can be directly tied to such traits as intelligence or homosexuality. Ultimately, the authors argue, we are now living with a new knowledge as powerful in its way as nuclear physics, and the stark choices that face us—between biological warfare and gene therapy, a new eugenics or a new agricultural revolution—will demand the full engagement of both scientists and citizens. Written in straightforward language but without denying the complexity of the issues, Genomes and What to Make of Them is both an up-to-date primer and a blueprint for the future.

The Tangled Tree

The Tangled Tree PDF Author: David Quammen
Publisher: Simon & Schuster
ISBN: 1476776636
Category : Science
Languages : en
Pages : 480

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).

Genomes 4

Genomes 4 PDF Author: T. A. Brown
Publisher: Garland Science
ISBN: 1351851292
Category : Science
Languages : en
Pages : 520

Book Description
Genomes 4 has been completely revised and updated. It is a thoroughly modern textbook about genomes and how they are investigated. As with Genomes 3, techniques come first, then genome anatomies, followed by genome function, and finally genome evolution. The genomes of all types of organism are covered: viruses, bacteria, fungi, plants, and animals including humans and other hominids. Genome sequencing and assembly methods have been thoroughly revised including a survey of four genome projects: human, Neanderthal, giant panda, and barley. Coverage of genome annotation emphasizes genome-wide RNA mapping, with CRISPR-Cas 9 and GWAS methods of determining gene function covered. The knowledge gained from these techniques forms the basis of the three chapters that describe the three main types of genomes: eukaryotic, prokaryotic (including eukaryotic organelles), and viral (including mobile genetic elements). Coverage of genome expression and replication is truly genomic, concentrating on the genome-wide implications of DNA packaging, epigenome modifications, DNA-binding proteins, non-coding RNAs, regulatory genome sequences, and protein-protein interactions. Also included are applications of transcriptome analysis, metabolomics, and systems biology. The final chapter is on genome evolution, focusing on the evolution of the epigenome, using genomics to study human evolution, and using population genomics to advance plant breeding. Established methods of molecular biology are included if they are still relevant today and there is always an explanation as to why the method is still important. Each chapter has a set of short-answer questions, in-depth problems, and annotated further reading. There is also an extensive glossary. Genomes 4 is the ideal text for upper level courses focused on genomes and genomics.
