Available in PDF, EPUB and Kindle. Book excerpt: Research in biology and all basic sciences has undergone profound transformations in recent decades. We have seen the development of extremely sophisticated techniques, allowing us to study, in an objective manner, questions that were still considered science fiction at the end of the 20th century. All of this has allowed us to develop an in-depth knowledge of vast subjects, such as the biology of the brain, for example. Fifty Years of Evolution in Biological Research presents a panorama of these different technical advances. However, at the same time, there has been an increase in the number of constraints on researchers, a monetization of research and a correlative pressure to continually publish in more prestigious journals. This has resulted in a certain degradation of the quality of research activity. This book analyzes this evolution and proposes solutions.

Available in PDF, EPUB and Kindle. Book excerpt: A new edition of Peter and Rosemary Grant’s classic account of their groundbreaking forty-year study of Darwin’s finches 40 Years of Evolution is a landmark study of the finches first made famous by Charles Darwin, one that documents as never before the evolution of species through natural selection. In this now-legendary study, renowned evolutionary biologists Peter and Rosemary Grant draw on a vast and unparalleled range of ecological, behavioral, and genetic data to continuously measure changes in finch populations over a period of four decades on the small island of Daphne Major in the Galápagos archipelago. In the years since the book’s publication, the field of genomics has developed greatly. In this newly revised edition of 40 Years of Evolution, the Grants combine the results of their historic field study with genomic analyses of their primary findings, resolve unanswered questions from the field, and provide invaluable insights into the genetic basis of beak and body size variation and the history of this iconic adaptive radiation.

Available in PDF, EPUB and Kindle. Book excerpt: A fiftieth birthday is a good one to celebrate-old enough to be ex perienced and mature, but not so old as to be an antique. And if the fifty years have spanned as much change in scientific affairs as has occurred during the lifetime of Biological Abstracts it is surely time for a stocktaking. The leaders of biology in 1926 simply could not have imagined the condi tions of 1976. And few biologists active in 1976 can imagine what 1926 was like. That was before the explosive growth of federal funds for research and development, before the huge swelling of graduate enrollments and degrees, before World War II, even before the Great Depression! A few old-timers can remember 1926, and Bill Steere will forgive me for calling him an old-timer. After all, he provides the evidence himself; as a graduate student he met the first editor when Biological Abstracts was only three years old, and he has known all its later editors and administra tive officers. What he does not say is that tn length of service to BIOSIS, in seniority, he stands among only a few past and present members of the board of trustees; nor does he mention that at least as frequently as any other biologist he has been called upon to serve on governmental and associational councils and committees dealing with policy and strategy concerning the abstracting, classification, and dissemination of scientific knowledge. Surely he was the right choice to write this history.

Download or read book Tempo and Mode in Evolution written by for the National Academy of Sciences and published by National Academies Press. This book was released on 1995-01-26 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since George Gaylord Simpson published Tempo and Mode in Evolution in 1944, discoveries in paleontology and genetics have abounded. This volume brings together the findings and insights of today's leading experts in the study of evolution, including Ayala, W. Ford Doolittle, and Stephen Jay Gould. The volume examines early cellular evolution, explores changes in the tempo of evolution between the Precambrian and Phanerozoic periods, and reconstructs the Cambrian evolutionary burst. Long-neglected despite Darwin's interest in it, species extinction is discussed in detail. Although the absence of data kept Simpson from exploring human evolution in his book, the current volume covers morphological and genetic changes in human populations, contradicting the popular claim that all modern humans descend from a single woman. This book discusses the role of molecular clocks, the results of evolution in 12 populations of Escherichia coli propagated for 10,000 generations, a physical map of Drosophila chromosomes, and evidence for "hitchhiking" by mutations.

Available in PDF, EPUB and Kindle. Book excerpt: An important look at a groundbreaking forty-year study of Darwin's finches Renowned evolutionary biologists Peter and Rosemary Grant have produced landmark studies of the Galápagos finches first made famous by Charles Darwin. In How and Why Species Multiply, they offered a complete evolutionary history of Darwin's finches since their origin almost three million years ago. Now, in their richly illustrated new book, 40 Years of Evolution, the authors turn their attention to events taking place on a contemporary scale. By continuously tracking finch populations over a period of four decades, they uncover the causes and consequences of significant events leading to evolutionary changes in species. The authors used a vast and unparalleled range of ecological, behavioral, and genetic data—including song recordings, DNA analyses, and feeding and breeding behavior—to measure changes in finch populations on the small island of Daphne Major in the Galápagos archipelago. They find that natural selection happens repeatedly, that finches hybridize and exchange genes rarely, and that they compete for scarce food in times of drought, with the remarkable result that the finch populations today differ significantly in average beak size and shape from those of forty years ago. The authors' most spectacular discovery is the initiation and establishment of a new lineage that now behaves as a new species, differing from others in size, song, and other characteristics. The authors emphasize the immeasurable value of continuous long-term studies of natural populations and of critical opportunities for detecting and understanding rare but significant events. By following the fates of finches for several generations, 40 Years of Evolution offers unparalleled insights into ecological and evolutionary changes in natural environments.

Book excerpt: “This brilliant book is a virtual Voyage of the Beagle! Carl Zimmer shows, with the benefit of a hundred and fifty years of hindsight, how right Darwin was.” —Steve Jones, author of Darwin’s Ghost Darwin’s The Origin of Species was breathtaking—beautifully written, staunchly defended, defiantly radical. Yet it emerged long before modern genetics, molecular biology, and contemporary findings in paleontology. In this remarkable book, a rich and up-to-date view of evolution is presented that explores the far-reaching implications of Darwin’s theory. At a time when controversies surrounding creationism and education are bursting into public consciousness, this book’s emphasis on the power, significance, and relevance of evolution will make it a catalyst for public debate. Evolution marks a turning point in the 150-year debate and will be an indispensable asset to any serious reader with an interest in the life sciences, a passion for truth in education, or a concern for the future of the planet. “The evolution of life over four billion years is a grand narrative, full of plots, intrigues, surprises and deaths. Carl Zimmer tells the tale with zest and style.” —Matt Ridley, New York Times–bestselling author “Proceeding from the flurry of preparations for Darwin’s famous voyage, Carl Zimmer leads us off on a journey of our own, tracking the development—and the implications—of one of the most powerful ideas in the biological sciences.” —Scientific American “Science writer Zimmer does a superb job of providing a sweeping overview of most of the topics critical to understanding evolution, presenting his material from both a historical and a topical perspective.” —Publishers Weekly “Popular science that will truly be popular.” —Booklist

Download or read book Fifty Years of Invasion Ecology written by David M. Richardson and published by John Wiley & Sons. This book was released on 2011-01-18 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasion ecology is the study of the causes and consequences of the introduction of organisms to areas outside their native range. Interest in this field has exploded in the past few decades. Explaining why and how organisms are moved around the world, how and why some become established and invade, and how best to manage invasive species in the face of global change are all crucial issues that interest biogeographers, ecologists and environmental managers in all parts of the world. This book brings together the insights of more than 50 authors to examine the origins, foundations, current dimensions and potential trajectories of invasion ecology. It revisits key tenets of the foundations of invasion ecology, including contributions of pioneering naturalists of the 19th century, including Charles Darwin and British ecologist Charles Elton, whose 1958 monograph on invasive species is widely acknowledged as having focussed scientific attention on biological invasions.

Download or read book Ontogeny and Phylogeny written by Stephen Jay Gould and published by Harvard University Press. This book was released on 1985-01-17 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Ontogeny recapitulates phylogeny” was Haeckel’s answer—the wrong one—to the most vexing question of nineteenth-century biology: what is the relationship between individual development (ontogeny) and the evolution of species and lineages (phylogeny)? In this, the first major book on the subject in fifty years, Stephen Jay Gould documents the history of the idea of recapitulation from its first appearance among the pre-Socratics to its fall in the early twentieth century. Mr. Gould explores recapitulation as an idea that intrigued politicians and theologians as well as scientists. He shows that Haeckel’s hypothesis—that human fetuses with gill slits are, literally, tiny fish, exact replicas of their water-breathing ancestors—had an influence that extended beyond biology into education, criminology, psychoanalysis (Freud and Jung were devout recapitulationists), and racism. The theory of recapitulation, Gould argues, finally collapsed not from the weight of contrary data, but because the rise of Mendelian genetics rendered it untenable. Turning to modern concepts, Gould demonstrates that, even though the whole subject of parallels between ontogeny and phylogeny fell into disrepute, it is still one of the great themes of evolutionary biology. Heterochrony—changes in developmental timing, producing parallels between ontogeny and phylogeny—is shown to be crucial to an understanding of gene regulation, the key to any rapprochement between molecular and evolutionary biology. Gould argues that the primary evolutionary value of heterochrony may lie in immediate ecological advantages for slow or rapid maturation, rather than in long-term changes of form, as all previous theories proclaimed. Neoteny—the opposite of recapitulation—is shown to be the most important determinant of human evolution. We have evolved by retaining the juvenile characters of our ancestors and have achieved both behavioral flexibility and our characteristic morphology thereby (large brains by prolonged retention of rapid fetal growth rates, for example). Gould concludes that “there may be nothing new under the sun, but permutation of the old within complex systems can do wonders. As biologists, we deal directly with the kind of material complexity that confers an unbounded potential upon simple, continuous changes in underlying processes. This is the chief joy of our science.”

Available in PDF, EPUB and Kindle. Book excerpt: Year 2009 was the triumph of Darwin as a global superstar, spinning from the pop icon to the actual understanding to what make him a great innovator, able to give a turn to whole modern culture. Does all this activity mean evolution has lost its ability to excite fear and opposition? After such a deluge of books, conferences, reviews, gadgets, what is today our vision on theory of Evolution and its Impact? These are the questions asked at an inter-academy conference held in Torino (May 27-29, 2010) among the Accademia delle Scienze di Torino, the Accademia Nazionale dei Lincei and the Berlin-Brandenburgische Akademie der Wissenschaften. The present book collects the contributions from the meeting, mixing styles, arguments, topics, history and philosophy of science, modern biology and epistemology . This kind of inter-disciplinary approach may appear erratic, but it conveys flashes of lights on the changing scene where the theory of evolution plays. This is in line with the idea to reopen the file of the Two Cultures, looking at shared problems, which are not yet really the Third Culture invoked by Charles Percy Snow half a century ago, but they can foster it, at least in such a pivotal domain as evolution. According to the philosopher Michael Ruse, the conclusion is “that in fifty years or a hundred years we will still have the theory of the Origin around. Great, precisely because it does not stand still, but remakes itself and grows and changes by virtue of the fact that it gives such a terrific foundation. Is Darwinism past its sell-by date? Not by a long chalk yet!”
