Pages : 486

Book Description
The Instant New York Times Bestseller! Was an advanced civilization lost to history in the global cataclysm that ended the last Ice Age? Graham Hancock, the internationally bestselling author, has made it his life's work to find out--and in America Before, he draws on the latest archaeological and DNA evidence to bring his quest to a stunning conclusion. We’ve been taught that North and South America were empty of humans until around 13,000 years ago – amongst the last great landmasses on earth to have been settled by our ancestors. But new discoveries have radically reshaped this long-established picture and we know now that the Americas were first peopled more than 130,000 years ago – many tens of thousands of years before human settlements became established elsewhere. Hancock's research takes us on a series of journeys and encounters with the scientists responsible for the recent extraordinary breakthroughs. In the process, from the Mississippi Valley to the Amazon rainforest, he reveals that ancient "New World" cultures share a legacy of advanced scientific knowledge and sophisticated spiritual beliefs with supposedly unconnected "Old World" cultures. Have archaeologists focused for too long only on the "Old World" in their search for the origins of civilization while failing to consider the revolutionary possibility that those origins might in fact be found in the "New World"? America Before: The Key to Earth's Lost Civilization is the culmination of everything that millions of readers have loved in Hancock's body of work over the past decades, namely a mind-dilating exploration of the mysteries of the past, amazing archaeological discoveries and profound implications for how we lead our lives today.

Pollinators and Pollination

Pollinators and Pollination PDF Author: Jeff Ollerton
Publisher: Pelagic Publishing Ltd
ISBN: 1784272299
Category : Science
Languages : en
Pages : 425

Book Description
A unique and personal insight into the ecology and evolution of pollinators, their relationships with flowers, and their conservation in a rapidly changing world. The pollination of flowers by insects, birds and other animals is a fundamentally important ecological function that supports both the natural world and human society. Without pollinators to facilitate the sexual reproduction of plants, the world would be a biologically poorer place in which to live, there would be an impact on food security, and human health would suffer. Written by one of the world’s leading pollination ecologists, this book provides an introduction to what pollinators are, how their interactions with flowers have evolved, and the fundamental ecology of these relationships. It explores the pollination of wild and agricultural plants in a variety of habitats and contexts, including urban, rural and agricultural environments. The author also provides practical advice on how individuals and organisations can study, and support, pollinators. As well as covering the natural history of pollinators and flowers, the author discusses their cultural importance, and the ways in which pollinator conservation has been portrayed from a political perspective. The book draws on field work experiences in South America, Africa, Australia, the Canary Islands and the UK. For over 30 years the author has spent his career researching how plants and pollinators evolve relationships, how these interactions function ecologically, their importance for society, and how we can conserve them in a rapidly changing world. This book offers a unique and personal insight into the science of pollinators and pollination, aimed at anyone who is interested in understanding these fascinating and crucial ecological interactions.

Careers in Geology

Careers in Geology PDF Author: Institute For Institute For Career Research
Publisher: Createspace Independent Publishing Platform
ISBN: 9781717285027
Category :
Languages : en
Pages : 38

Book Description
GEOLOGY IS THE SCIENTIFIC STUDY OF THE EARTH, its composition, its processes, and the forces that act upon it. It is a broad subject that covers very specific aspects from glaciers and volcanoes, to gem stones and energy resources, to changing land formations and mass extinctions. It includes every area - the earth's core, ocean floor, deep canyons, mountaintops, and even the atmosphere. Geologists spend most of their time outdoors, often in remote areas. They dig up fossils, take soil samples, create maps, and gather lots of photographic evidence. They study the weather and investigate potential geological activity in order to predict natural disasters and potentially save people from the ravages of tornadoes, earthquakes, tsunamis, or volcanic eruptions. There are dozens of different jobs that a geologist can hold. Each utilizes the knowledge and skills acquired from the same basic training and education. What any one geologist does depends on the job title or area of specialization. For example, environmental geologists are concerned with the safe use of natural resources. They test soil and water for signs of toxins after accidents, help create plans for cleanup, and make sure areas are safe for residents. Hydrogeologists work primarily with water. They study how water moves, how and where it becomes available to communities, ways to increase water supplies, and how to minimize possible pollution. Petroleum geologists search for sources of oil and gas, and develop methods for safe extraction. The minimum educational requirement to become a geologist is a bachelor's degree in geology, though many employers prefer a master's degree. In either case, those entering the field can expect to find jobs waiting for them. In fact, industry leaders predict that some areas will experience shortages of trained professionals as the demand for renewable and safe energy, more accurate hazard weather plans, global environmental safety, and answers to the threat of climate change grows in importance.

Biocode

Biocode PDF Author: Dawn Field
Publisher: American Chemical Society
ISBN: 0199687757
Category : Science
Languages : en
Pages : 209

Book Description
The living world runs on genomic software - what Dawn Field and Neil Davies call the 'biocode' - the sum of all DNA on Earth. In Biocode, they tell the story of a new age of scientific discovery: the growing global effort to read and map the biocode, and what that might mean for the future. The structure of DNA was identified in 1953, and the whole human genome was mapped by 2003. Since then the new field of genomics has mushroomed and is now operating on an industrial scale. Genomes can now be sequenced rapidly and increasingly cheaply. The genomes of large numbers of organisms from mammals to microbes, have been mapped. Getting your genome sequenced is becoming affordable for many. You too can check paternity, find out where your ancestors came from, or whether you are at risk of some diseases. Some check out the pedigree of their pets, while others turn genomes into art. A stray hair is enough to crudely reconstruct the face of the owner. From reading to constructing: the first steps to creating artificial life have already been taken. Some may find the rapidity of developments, and the potential for misuse, alarming. But they also open up unprecedented possibilities. The ability to read DNA has changed how we view ourselves and understand our place in nature. From the largest oceans, to the insides of our guts, we are able to explore the biosphere as never before, from the genome up. Sequencing technology has made the invisible world of microbes visible, and biodiversity genomics is revealing whole new worlds within us and without. The findings are transformational: we are all ecosystems now. Already the first efforts at 'barcoding' entire ecological communities and creating 'genomic observatories' have begun. The future, the authors argue, will involve biocoding the entire planet.

Catching Fire

Catching Fire PDF Author: Richard Wrangham
Publisher: Profile Books
ISBN: 1847652107
Category : Science
Languages : en
Pages : 318

Book Description
In this stunningly original book, Richard Wrangham argues that it was cooking that caused the extraordinary transformation of our ancestors from apelike beings to Homo erectus. At the heart of Catching Fire lies an explosive new idea: the habit of eating cooked rather than raw food permitted the digestive tract to shrink and the human brain to grow, helped structure human society, and created the male-female division of labour. As our ancestors adapted to using fire, humans emerged as "the cooking apes". Covering everything from food-labelling and overweight pets to raw-food faddists, Catching Fire offers a startlingly original argument about how we came to be the social, intelligent, and sexual species we are today. "This notion is surprising, fresh and, in the hands of Richard Wrangham, utterly persuasive ... Big, new ideas do not come along often in evolution these days, but this is one." -Matt Ridley, author of Genome

Thinking in Systems

Thinking in Systems PDF Author: Donella Meadows
Publisher: Chelsea Green Publishing
ISBN: 1603581480
Category : Science
Languages : en
Pages : 242

Book Description
The classic book on systems thinking—with more than half a million copies sold worldwide! "This is a fabulous book... This book opened my mind and reshaped the way I think about investing."—Forbes "Thinking in Systems is required reading for anyone hoping to run a successful company, community, or country. Learning how to think in systems is now part of change-agent literacy. And this is the best book of its kind."—Hunter Lovins In the years following her role as the lead author of the international bestseller, Limits to Growth—the first book to show the consequences of unchecked growth on a finite planet—Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001. Thinking in Systems is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global. Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life. Some of the biggest problems facing the world—war, hunger, poverty, and environmental degradation—are essentially system failures. They cannot be solved by fixing one piece in isolation from the others, because even seemingly minor details have enormous power to undermine the best efforts of too-narrow thinking. While readers will learn the conceptual tools and methods of systems thinking, the heart of the book is grander than methodology. Donella Meadows was known as much for nurturing positive outcomes as she was for delving into the science behind global dilemmas. She reminds readers to pay attention to what is important, not just what is quantifiable, to stay humble, and to stay a learner. In a world growing ever more complicated, crowded, and interdependent, Thinking in Systems helps readers avoid confusion and helplessness, the first step toward finding proactive and effective solutions.

Tree

Tree PDF Author: David Suzuki
Publisher: Greystone Books Ltd
ISBN: 1926685539
Category : Nature
Languages : en
Pages : 200

Book Description
“Only God can make a tree,” wrote Joyce Kilmer in one of the most celebrated of poems. In Tree: A Life Story, authors David Suzuki and Wayne Grady extend that celebration in a “biography” of this extraordinary — and extraordinarily important — organism. A story that spans a millennium and includes a cast of millions but focuses on a single tree, a Douglas fir, Tree describes in poetic detail the organism’s modest origins that begin with a dramatic burst of millions of microscopic grains of pollen. The authors recount the amazing characteristics of the species, how they reproduce and how they receive from and offer nourishment to generations of other plants and animals. The tree’s pivotal role in making life possible for the creatures around it — including human beings — is lovingly explored. The richly detailed text and Robert Bateman’s original art pay tribute to this ubiquitous organism that is too often taken for granted.
