Cradle Of Life

Download or read book Cradle of Life written by J. William Schopf and published by Princeton University Press. This book was released on 2021-10-12 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the greatest mysteries in reconstructing the history of life on Earth has been the apparent absence of fossils dating back more than 550 million years. We have long known that fossils of sophisticated marine life-forms existed at the dawn of the Cambrian Period, but until recently scientists had found no traces of Precambrian fossils. The quest to find such traces began in earnest in the mid-1960s and culminated in one dramatic moment in 1993 when William Schopf identified fossilized microorganisms three and a half billion years old. This startling find opened up a vast period of time--some eighty-five percent of Earth's history--to new research and new ideas about life's beginnings. In this book, William Schopf, a pioneer of modern paleobiology, tells for the first time the exciting and fascinating story of the origins and earliest evolution of life and how that story has been unearthed. Gracefully blending his personal story of discovery with the basics needed to understand the astonishing science he describes, Schopf has produced an introduction to paleobiology for the interested reader as well as a primer for beginning students in the field. He considers such questions as how did primitive bacteria, pond scum, evolve into the complex life-forms found at the beginning of the Cambrian Period? How do scientists identify ancient microbes and what do these tiny creatures tell us about the environment of the early Earth? (And, in a related chapter, Schopf discusses his role in the controversy that swirls around recent claims of fossils in the famed meteorite from Mars.) Like all great teachers, Schopf teaches the non-specialist enough about his subject along the way that we can easily follow his descriptions of the geology, biology, and chemistry behind these discoveries. Anyone interested in the intriguing questions of the origins of life on Earth and how those origins have been discovered will find this story the best place to start.

Download or read book Cradle of Life written by Vincent Carruthers and published by Penguin Random House South Africa. This book was released on 2019-08-01 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cradle of Humankind World Heritage Site situated in the heart of the Magaliesberg Biosphere Reserve is the jewel in South Africa’s evolutionary crown: an area ‘of outstanding universal value’, it has attracted world-wide interest and furnished key evidence about where, when and how we came to be. The greater Magaliesberg area is peppered with some 200 caves and has a unique geology, history and biodiversity. For decades now, specialists have been combing the area to uncover evidence of our heritage. In his spectacular new title, Vincent Carruthers guides readers along a timeline, from the birth of our planet through to developments of the twenty first century. Along the way he documents the formation of our landscapes and the emergence of life, the rise of hominins, the stone and iron ages, early settlement, migrations, wars and modern developments in the Magaliesberg – the entire evolution of life up to the present, as we know it. Vividly illustrated with photographs, maps and diagrams, Cradle of Life portrays the intrigue and importance of the site, taking readers on a magical journey of discovery. Sales points: Authoritative handling of a complex topic; lavishly illustrated with colourful photos and diagrams; chronological detailing of key events from the beginning of time up to the modern age; accessible and appealing to a wide range of users, from visitors to students, enthusiasts and academics

Download or read book The Cradle of Humanity written by Mark Maslin and published by Oxford University Press. This book was released on 2017 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the fundamental questions of our existence is why we are so smart. There are lots of drawbacks to having a large brain, including the huge food intake needed to keep the organ running, the frequency with which it goes wrong, and our very high infant and mother mortality rates compared with other mammals, due to the difficulty of giving birth to offspring with very large heads. So why did evolution favour the brainy ape? This question has been widely debated among biological anthropologists, and in recent years, Maslin and his colleagues have pioneered a new theory that might just be the answer. Looking back to a crucial period some 1.9 million years ago, when brain capacity increased by as much as 80%, The Cradle of Humanity explores the implications of two adaptive responses by our hominin ancestors to rapid climatic changes - big jaws, and big brains. Maslin argues that the impact of changing landscapes and fluctuating climates that led to the appearance of intermittent freshwater lakes in East Africa may have played a key role in human evolution. Alongside the physical evidence of fossils and tools, he considers social theories of why a large, complex brain would have provided a major advantage when trying to survive in the constantly changing East African landscape.
