This book was released on 2023-11-21 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Un panorama general, básico y didáctico sobre la singularidad genética y biológica de la especie humana. Tras la creación del universo con el big-bang hace 13.700 millones de años brotó la vida en un planeta idóneo para su expansión y diversificación. En el libro se detallan los mecanismos de la evolución y de la aparición del Homo sapiens a partir de unos ancestros prehomínidos en el centro de África, hasta su expansión por todo el mundo. Se describen los procesos de la hominización y humanización y las especiales características del ser humano. Se explica el significado del “fenómeno humano” y el por qué y el cómo del resurgir de una especie tan singular. La única que asciende al mundo de la racionalidad y que en consecuencia vive su vida de forma consciente, se comunica con sus congéneres, crea la cultura y domina su entorno con un sentido ético y de trascendencia. En el libro se describen los fundamentos genéticos de nuestros rasgos biológicos, los determinantes genéticos y ambientales que influyen en el comportamiento humano, las enfermedades hereditarias y los detalles de nuestro genoma en relación con el de los demás seres vivos. Se distingue entre lo innato y lo adquirido. Se derriban los mitos y se asientan las pruebas de lo que es genuinamente humano y lo que no lo es. También se aborda el futuro de la humanidad en la era de las tecnologías emergentes, con los desafíos éticos de la manipulación genética y las corrientes materialistas que tratan de conducir a nuestra singular especie a la utopía transhumanista y posthumanista.

Available in PDF, EPUB and Kindle. Book excerpt: "THE ULTIMATE DINOSAUR BIOGRAPHY," hails Scientific American: A thrilling new history of the age of dinosaurs, from one of our finest young scientists. "A masterpiece of science writing." —Washington Post A New York Times Bestseller • Goodreads Choice Awards Winner • A BEST BOOK OF THE YEAR: Smithsonian, Science Friday, The Times (London), Popular Mechanics, Science News "This is scientific storytelling at its most visceral, striding with the beasts through their Triassic dawn, Jurassic dominance, and abrupt demise in the Cretaceous." —Nature The dinosaurs. Sixty-six million years ago, the Earth’s most fearsome creatures vanished. Today they remain one of our planet’s great mysteries. Now The Rise and Fall of the Dinosaurs reveals their extraordinary, 200-million-year-long story as never before. In this captivating narrative (enlivened with more than seventy original illustrations and photographs), Steve Brusatte, a young American paleontologist who has emerged as one of the foremost stars of the field—naming fifteen new species and leading groundbreaking scientific studies and fieldwork—masterfully tells the complete, surprising, and new history of the dinosaurs, drawing on cutting-edge science to dramatically bring to life their lost world and illuminate their enigmatic origins, spectacular flourishing, astonishing diversity, cataclysmic extinction, and startling living legacy. Captivating and revelatory, The Rise and Fall of the Dinosaurs is a book for the ages. Brusatte traces the evolution of dinosaurs from their inauspicious start as small shadow dwellers—themselves the beneficiaries of a mass extinction caused by volcanic eruptions at the beginning of the Triassic period—into the dominant array of species every wide-eyed child memorizes today, T. rex, Triceratops, Brontosaurus, and more. This gifted scientist and writer re-creates the dinosaurs’ peak during the Jurassic and Cretaceous, when thousands of species thrived, and winged and feathered dinosaurs, the prehistoric ancestors of modern birds, emerged. The story continues to the end of the Cretaceous period, when a giant asteroid or comet struck the planet and nearly every dinosaur species (but not all) died out, in the most extraordinary extinction event in earth’s history, one full of lessons for today as we confront a “sixth extinction.” Brusatte also recalls compelling stories from his globe-trotting expeditions during one of the most exciting eras in dinosaur research—which he calls “a new golden age of discovery”—and offers thrilling accounts of some of the remarkable findings he and his colleagues have made, including primitive human-sized tyrannosaurs; monstrous carnivores even larger than T. rex; and paradigm-shifting feathered raptors from China. An electrifying scientific history that unearths the dinosaurs’ epic saga, The Rise and Fall of the Dinosaurs will be a definitive and treasured account for decades to come. Includes 75 images, world maps of the prehistoric earth, and a dinosaur family tree.

Download or read book A New Reference Grammar of Modern Spanish written by John Butt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: (abridged and revised) This reference grammar offers intermediate and advanced students a reason ably comprehensive guide to the morphology and syntax of educated speech and plain prose in Spain and Latin America at the end of the twentieth century. Spanish is the main, usually the sole official language of twenty-one countries,} and it is set fair to overtake English by the year 2000 in numbers 2 of native speakers. This vast geographical and political diversity ensures that Spanish is a good deal less unified than French, German or even English, the latter more or less internationally standardized according to either American or British norms. Until the 1960s, the criteria of internationally correct Spanish were dictated by the Real Academia Espanola, but the prestige of this institution has now sunk so low that its most solemn decrees are hardly taken seriously - witness the fate of the spelling reforms listed in the Nuevas normas de prosodia y ortograjia, which were supposed to come into force in all Spanish-speaking countries in 1959 and, nearly forty years later, are still selectively ignored by publishers and literate persons everywhere. The fact is that in Spanish 'correctness' is nowadays decided, as it is in all living languages, by the consensus of native speakers; but consensus about linguistic usage is obviously difficult to achieve between more than twenty independent, widely scattered and sometimes mutually hostile countries. Peninsular Spanish is itself in flux.

Download or read book Biodiversity of Angola written by Brian J. Huntley and published by Springer. This book was released on 2019-02-20 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access multi-authored book presents a 'state of the science' synthesis of knowledge on the biodiversity of Angola, based on sources in peer-reviewed journals, in books and where appropriate, unpublished official reports. The book identifies Angola as one of the most biologically diverse countries in Africa, but notes that its fauna, flora, habitats and the processes that drive the dynamics of its ecosystems are still very poorly researched and documented. This 'state of the science' synthesis is for the use of all students of Angola's biodiversity, and for those responsible for the planning, development and sustainable management of the country's living resources. The volume brings together the results of expeditions and research undertaken in Angola since the late eighteenth century, with emphasis on work conducted in the four decades since Angola's independence in 1975. The individual chapters have been written by leaders in their fields, and reviewed by peers familiar with the region.

Download or read book Oaks Physiological Ecology Exploring the Functional Diversity of Genus Quercus L written by Eustaquio Gil-Pelegrín and published by Springer. This book was released on 2017-12-12 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 500 species distributed all around the Northern Hemisphere, the genus Quercus L. is a dominant element of a wide variety of habitats including temperate, tropical, subtropical and mediterranean forests and woodlands. As the fossil record reflects, oaks were usual from the Oligocene onwards, showing the high ability of the genus to colonize new and different habitats. Such diversity and ecological amplitude makes genus Quercus an excellent framework for comparative ecophysiological studies, allowing the analysis of many mechanisms that are found in different oaks at different level (leaf or stem). The combination of several morphological and physiological attributes defines the existence of different functional types within the genus, which are characteristic of specific phytoclimates. From a landscape perspective, oak forests and woodlands are threatened by many factors that can compromise their future: a limited regeneration, massive decline processes, mostly triggered by adverse climatic events or the competence with other broad-leaved trees and conifer species. The knowledge of all these facts can allow for a better management of the oak forests in the future.

Download or read book Late Cretaceous Paleogene West Antarctica Terrestrial Biota and its Intercontinental Affinities written by Marcelo Reguero and published by Springer Science & Business Media. This book was released on 2012-12-19 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most intriguing paleobiogeographical phenomena involving the origins and gradual sundering of Gondwana concerns the close similarities and, in most cases, inferred sister-group relationships of a number of terrestrial and freshwater vertebrate taxa, e.g., dinosaurs, flying birds, mammals, etc., recovered from uppermost Cretaceous/ Paleogene deposits of West Antarctica, South America, and NewZealand/Australia. For some twenty five extensive and productive investigations in the field of vertebrate paleontology has been carried out in latest Cretaceous and Paleogene deposits in the James Ross Basin, northeast of the Antarctic Peninsula (AP), West Antarctica, on the exposed sequences on James Ross, Vega, Seymour (=Marambio) and Snow Hill islands respectively. The available geological, geophysical and marine faunistic evidence indicates that the peninsular (AP) part of West Antarctica and the western part of the tip of South America (Magallanic Region, southern Chile) were positioned very close in the latest Cretaceous and early Paleogene favoring the “Overlapping” model of South America-Antarctic Peninsula paleogeographic reconstruction. Late Cretaceous deposits from Vega, James Ross, Seymour and Snow Hill islands have produced a discrete number of dinosaur taxa and a number of advanced birds together with four mosasaur and three plesiosaur taxa, and a few shark and teleostean taxa.

Book excerpt: A world-renowned paleontologist reveals groundbreaking science that trumps science fiction: how to grow a living dinosaur. Over a decade after Jurassic Park, Jack Horner and his colleagues in molecular biology labs are in the process of building the technology to create a real dinosaur. Based on new research in evolutionary developmental biology on how a few select cells grow to create arms, legs, eyes, and brains that function together, Jack Horner takes the science a step further in a plan to "reverse evolution" and reveals the awesome, even frightening, power being acquired to recreate the prehistoric past. The key is the dinosaur's genetic code that lives on in modern birds- even chickens. From cutting-edge biology labs to field digs underneath the Montana sun, How to Build a Dinosaur explains and enlightens an awesome new science.

Download or read book Inventing English written by Seth Lerer and published by Columbia University Press. This book was released on 2015-08-25 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: A history of English from the age of Beowulf to the rap of Eminem, “written with real authority, enthusiasm and love for our unruly and exquisite language” (The Washington Post). Many have written about the evolution of grammar, pronunciation, and vocabulary, but only Seth Lerer situates these developments within the larger history of English, America, and literature. This edition of his “remarkable linguistic investigation” (Booklist) features a new chapter on the influence of biblical translation and an epilogue on the relationship of English speech to writing. A unique blend of historical and personal narrative, both “erudite and accessible” (The Globe and Mail), Inventing English is the surprising tale of a language that is as dynamic as the people to whom it belongs. “Lerer is not just a scholar; he's also a fan of English—his passion is evident on every page of this examination of how our language came to sound—and look—as it does and how words came to have their current meanings…the book percolates with creative energy and will please anyone intrigued by how our richly variegated language came to be.”—Publishers Weekly (starred review)

Download or read book T rex and the Crater of Doom written by Walter Alvarez and published by Princeton University Press. This book was released on 2015-09-15 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished. This horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.
