Book Synopsis Cambrian Ocean World by : John Foster
Download or read book Cambrian Ocean World written by John Foster and published by Indiana University Press. This book was released on 2014-06-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, aimed at the general reader, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth’s history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies. Grazing, predation, and multi-tiered ecosystems with animals living in, on, or above the sea floor became common. The cascade of interaction led to an ever-increasing diversification of animal body types. By the end of the period, the ancestors of sponges, corals, jellyfish, worms, mollusks, brachiopods, arthropods, echinoderms, and vertebrates were all in place. The evidence of this Cambrian "explosion" is preserved in rocks all over the world, including North America, where the seemingly strange animals of the period are preserved in exquisite detail in deposits such as the Burgess Shale in British Columbia. Cambrian Ocean World tells the story of what is, for us, the most important period in our planet’s long history.

Book excerpt: The Cambrian Period records one of the most extraordinary transitions in the history of life. Although animals may have first appeared nearly 700 million years ago, with the earliest sponges, their initial diversifications appear to have been modest until a richly diverse fossil fauna appeared abruptly about 170 million years later. In The Cambrian Explosion, Erwin and Valentine synthesize research from many fields to explain why there was such remarkable novelty of animal forms.
Book Synopsis The Cambrian Period by : Charles River
Download or read book The Cambrian Period written by Charles River and published by . This book was released on 2020-10-16 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: *Includes pictures *Includes a bibliography for further reading The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. The current view of science is that Earth is around 4.6 billion years old, and the first 4 billion years of its development are known as the Precambrian period. For the first billion years or so, there was no life in Earth. Then the first single-celled life-forms, early bacteria and algae, began to emerge. It's unclear where they came from or even if they originated on this planet at all, but this gradual development continued until around four billion years ago when suddenly (in geological terms) more complex forms of life began to emerge. Scientists call this time of an explosion of new forms of life the Paleozoic Era, and it stretched from around 541-250 million years ago (Mya). In the oceans and then on land, new creatures and plants began to appear in bewildering variety, and by the end of this period, life on Earth had diversified into a myriad of complex forms that filled virtually every habitat and niche available in the seas and on the planet's only continent, Pangea. Despite all of the scientific advances made in the past few centuries, including an enhanced understanding of Earth's geological past, very little is known about the planet's early history. It is generally accepted that the planet formed somewhere in the region of 4.5 billion years ago, and at some point, the first life appeared in the form of tiny, single-celled creatures, but scientists are unsure of what this life looked like. One of the problems for those seeking to trace the history of life on Earth is that modern scholars are almost entirely dependent on fossil records, but the earliest types of life left few fossils. The best fossils are formed from the bones and hard body parts of dead creatures, but the earliest types of life were so small that they had no bones or cartilage and thus left no fossils. Thus, even though the Precambrian Period (4,600-541 millions of years ago (Mya)) covers over 80% of the entire history of the planet, scientists have very little idea of what forms of life existed then. Then, as Earth entered the Cambrian Period, there was a relatively sudden increase in life form diversity throughout the oceans. Completely new forms of life, more complex and more diverse than anything that had been seen before, began to spread. This acceleration in the evolution of new forms of life was so dramatic that this has come to be known as the "Cambrian explosion." Although new species in the Cambrian explosion developed almost entirely in the oceans, the land was not entirely devoid of life. Though there were no plants or animals, mats of cyanobacteria and other types of microbes covered large terrestrial areas. Scientists have discovered the tracks of a creature that were left in mud that existed 551 Mya, and those tracks were left by leg-like appendages. Was this a fish-like creature that temporarily invaded the land, or was it something completely different than anything that exists today? There is no general consensus, but the Cambrian Period left a rich fossil record that provides a clear idea of the development of life during this time. At the same time, new discoveries are continually being made, and the more scientists discover about this mysterious period, the more their understanding of ancient Earth changes. The Cambrian Period: The History and Legacy of the Start of Complex Life on Earth looks at the development of the era, the extinction event that preceded it, and how life began to evolve during it. Along with pictures depicting important people, places, and events, you will learn about the Cambrian Period like never before.
Book Synopsis Darwin's Doubt by : Stephen C. Meyer
Download or read book Darwin's Doubt written by Stephen C. Meyer and published by Harper Collins. This book was released on 2013-06-18 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Charles Darwin finished The Origin of Species, he thought that he had explained every clue, but one. Though his theory could explain many facts, Darwin knew that there was a significant event in the history of life that his theory did not explain. During this event, the “Cambrian explosion,” many animals suddenly appeared in the fossil record without apparent ancestors in earlier layers of rock. In Darwin’s Doubt, Stephen C. Meyer tells the story of the mystery surrounding this explosion of animal life—a mystery that has intensified, not only because the expected ancestors of these animals have not been found, but because scientists have learned more about what it takes to construct an animal. During the last half century, biologists have come to appreciate the central importance of biological information—stored in DNA and elsewhere in cells—to building animal forms. Expanding on the compelling case he presented in his last book, Signature in the Cell, Meyer argues that the origin of this information, as well as other mysterious features of the Cambrian event, are best explained by intelligent design, rather than purely undirected evolutionary processes.

Book Synopsis Darwin's Lost World by : Martin Brasier
Download or read book Darwin's Lost World written by Martin Brasier and published by OUP Oxford. This book was released on 2010-03-11 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin made a powerful argument for evolution in the Origin of Species, based on all the evidence available to him. But a few things puzzled him. One was how inheritance works - he did not know about genes. This book concerns another of Darwin's Dilemmas, and the efforts of modern palaeontologists to solve it. What puzzled Darwin is that the most very ancient rocks, before the Cambrian, seemed to be barren, when he would expect them to be teeming with life. Darwin speculated that this was probably because the fossils had not been found yet. Decades of work by modern palaeontologists have indeed brought us amazing fossils from far beyond the Cambrian, from the depths of the Precambrian, so life was certainly around. Yet the fossils are enigmatic, and something does seem to happen around the Cambrian to speed up evolution drastically and produce many of the early forms of animals we know today. In this book, Martin Brasier, a leading palaeontologist working on early life, takes us into the deep, dark ages of the Precambrian to explore Darwin's Lost World. Decoding the evidence in these ancient rocks, piecing together the puzzle of what happened over 540 million years ago to drive what is known as the Cambrian Explosion, is very difficult. The world was vastly different then from the one we know now, and we are in terrain with few familiar landmarks. Brasier is a master storyteller, and combines the account of what we now know of the strange creatures of these ancient times with engaging and amusing anecdotes from his expeditions to Siberia, Outer Mongolia, Barbuda, and other places, giving a vivid impression of the people, places, and challenges involved in such work. He ends by presenting his own take on the Cambrian Explosion, based on the picture emerging from this very active field of research. A vital clue involves worms - burrowing worms are one of the key signs of the start of the Cambrian. This is fitting: Darwin was inordinately fond of worms.
Book Synopsis Why Evolution is True by : Jerry A. Coyne
Download or read book Why Evolution is True written by Jerry A. Coyne and published by OUP Oxford. This book was released on 2010-01-14 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: For all the discussion in the media about creationism and 'Intelligent Design', virtually nothing has been said about the evidence in question - the evidence for evolution by natural selection. Yet, as this succinct and important book shows, that evidence is vast, varied, and magnificent, and drawn from many disparate fields of science. The very latest research is uncovering a stream of evidence revealing evolution in action - from the actual observation of a species splitting into two, to new fossil discoveries, to the deciphering of the evidence stored in our genome. Why Evolution is True weaves together the many threads of modern work in genetics, palaeontology, geology, molecular biology, anatomy, and development to demonstrate the 'indelible stamp' of the processes first proposed by Darwin. It is a crisp, lucid, and accessible statement that will leave no one with an open mind in any doubt about the truth of evolution.
Book Synopsis The Story of Life by : Richard Southwood
Download or read book The Story of Life written by Richard Southwood and published by OUP Oxford. This book was released on 2003-01-16 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did life begin? What was 'snowball earth'? Why did the dinosaurs become extinct? Are we all descended from 'African Eve'? Will humans be responsible for the next major extinction? These and many other fundamental questions are addressed in this masterly account of The Story of Life, by eminent biologist and teacher Richard Southwood. The story unfolds with the formation of the earth around four thousand million years ago. Life first emerged a hundred million years later, and it took another fifteen million years for more complex life-forms to appear. Periods of relative calm were punctuated by five major extinctions, with innumerable minor jolts along the way. Then, five million years ago, an able ape evolved that gradually came to dominate and control the other animals and plants. The future now lies in the hands of this single species, Homo sapiens. In this carefully crafted story, Southwood's love of his subject, and for the life he describes, shines through, to engage and inform scientist and general reader alike.
Book Synopsis The Trilobite Book by : Riccardo Levi-Setti
Download or read book The Trilobite Book written by Riccardo Levi-Setti and published by University of Chicago Press. This book was released on 2014-05-21 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: A scientist recounts his global adventure documenting trilobite fossils in this full-color book perfect for armchair paleontologists. Distant relatives of modern lobsters, horseshoe crabs, and spiders, trilobites swam the planet’s prehistoric seas for 300 million years, from the Lower Cambrian to the end of the Permian eras—and they did so very capably. Trilobite fossils have been unearthed on every continent, with more than 20,000 species identified by science. One of the most arresting animals of our pre-dinosaur world, trilobites are also favorites among the fossil collectors of today, their crystalline eyes often the catalyst for a lifetime of paleontological devotion. And there is no collector more devoted—or more venerated—than Riccardo Levi-Setti. With The Trilobite Book, a much-anticipated follow-up to his classic Trilobites, Levi-Setti brings us a glorious and revealing guide to these surreal arthropods of ancient Earth. Featuring specimens from Bohemia to Newfoundland, California to the Tucson Gem and Mineral Show, and Wales to the Anti-Atlas Mountains of Morocco, Levi-Setti’s magnificent book reanimates these “butterflies of the seas” in 235 astonishing full-color photographs. All original, Levi-Setti’s images serve as the jumping-off point for tales of his global quests in search of these highly sought-after fossils; for discussions of their mineralogical origins, as revealed by their color; and for unraveling the role of the now-extinct trilobites in our planetary history. Sure to enthrall paleontologists with its scientific insights and amateur enthusiasts with its beautiful and informative images, The Trilobite Book combines the best of science, technology, aesthetics, and personal adventure. It will inspire new collectors for eras to come. Praise for The Trilobite Book “[The Trilobite Book]marries the intertwined story of [Levi-Setti’s] global hunt for specimens and trilobites’ place in prehistory with 235 superb color photographs of select fossils. Perhaps most astounding is the array found by Arkadiy Evdokimov in Russia: their preservation is exquisite, down to the rococo flourishes of curving spines and protuberant, complex eyes.” —Barbara Kiser, Nature “This gorgeous, well-researched book is a must-have for anyone interested in these prehistoric creatures.” —Carla Sinclair, Boing Boing

Book Synopsis Life on a Young Planet by : Andrew H. Knoll
Download or read book Life on a Young Planet written by Andrew H. Knoll and published by Princeton University Press. This book was released on 2015-03-22 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australopithecines, dinosaurs, trilobites--such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making. In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.
Download or read book The Cambrian Way written by George Tod and published by Cicerone Press Limited. This book was released on 2022-03-17 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dubbed 'the mountain connoisseurs' walk', the Cambrian Way stretches 479km between the mighty castles of Cardiff in the south and Conwy on the north coast. Traversing the heartland of Wales, the challenging route crosses the Brecon Beacons, the Cambrian Mountains and Snowdonia, passing through two national parks and visiting many of the country's iconic summits, including Pen y Fan, Pumlumon, Cadair Idris and Snowdon itself. It can be walked in three weeks (or in shorter sections) and is suitable for experienced hillwalkers with sound navigational skills. The guide presents the route in 21 stages, offering comprehensive route description illustrated with OS 1:50,000 mapping and elevation profiles. Details of accommodation and facilities are provided, along with a helpful trek planner showing their distribution along the route: although the trail passes through remote areas, it is possible to stay under a roof every night - though camping is also a possibility, should you prefer. There are background notes on Wales's history and geology and local points of interest, and a glossary of Welsh place-names, useful contacts and accommodation listings can be found in the appendices. From the Black Mountains to the Rhinogau, Glyderau and Carneddau, the route takes in lofty ridges, striking peaks and picturesque lakes. There are also fascinating glimpses into the country's ancient and more recent past: Iron Age hillforts, Norman castles, a Cistercian abbey, the Chartist Cave and relics from the mining industry. Offering superlative scenery, the Cambrian Way is a celebration of some of the best mountain walking Wales has to offer and promises a unique opportunity to immerse yourself in these celebrated landscapes.
