Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1957, The Uniqueness of the Individual is a collection of 9 essays published from the ten years preceding publication. The essays deal with some of the central problems of biology. These are among the questions put and answered from the standpoint of modern experimental biology. What is ageing and how is it measured? What theories have been held to account for it, and with what success? Did ageing evolve, and if so how? Is Lamarckism and adequate explanation of evolutionary process? Does evolution sometimes go wrong? Do human beings evolve in a way peculiar to themselves? Other essays touch upon the problems of scientific method and of growth and transformation. This book will be of interest to natural historians, evolutionists and anthropologists.

Available in PDF, EPUB and Kindle. Book excerpt: "This volume provides a series of essays on open questions in ecology with the overarching goal being to outline to the most important, most interesting or most fundamental problems in ecology that need to be addressed. The contributions span ecological subfields, from behavioral ecology and population ecology to disease ecology and conservation and range in tone from the technical to more personal meditations on the state of the field. Many of the chapters start or end in moments of genuine curiosity, like one which takes up the question of why the world is green or another which asks what might come of a thought experiment in which we "turn-off" evolution entirely"--
Download or read book The World s 20 Greatest Unsolved Problems written by John R. Vacca and published by Prentice-Hall PTR. This book was released on 2005 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Phebe Hedges, a woman in East Hampton, New York, walked into the sea in 1806, she made visible the historical experience of a family affected by the dreaded disorder of movement, mind, and mood her neighbors called St.Vitus's dance. Doctors later spoke of Huntington’s chorea, and today it is known as Huntington's disease. This book is the first history of Huntington’s in America. Starting with the life of Phebe Hedges, Alice Wexler uses Huntington’s as a lens to explore the changing meanings of heredity, disability, stigma, and medical knowledge among ordinary people as well as scientists and physicians. She addresses these themes through three overlapping stories: the lives of a nineteenth-century family once said to “belong to the disease”; the emergence of Huntington’s chorea as a clinical entity; and the early-twentieth-century transformation of this disorder into a cautionary eugenics tale. In our own era of expanding genetic technologies, this history offers insights into the social contexts of medical and scientific knowledge, as well as the legacy of eugenics in shaping both the knowledge and the lived experience of this disease.

Download or read book Unsolved Mysteries of Science written by John Malone and published by Turner Publishing Company. This book was released on 2008-05-02 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: A LIVELY EXPLORATION OF THE BIGGEST QUESTIONS IN SCIENCE How Did the Universe Begin? The Big Bang has been the accepted theory for decades, but does it explain everything? How Did Life on Earth Get Started? What triggered the cell division that started the evolutionary chain? Did life come from outer space, buried in a chunk of rock? What is Gravity? Newton's apple just got the arguments started, Einstein made things more complicated. Just how does gravity fit in with quantum theory? What Is the Inside of the Earth Like? What exactly is happening beneath our feet, and can we learn enough to help predict earthquakes and volcanic eruptions? How Do We Learn Language? Is language acquisition an inborn biological ability, or does every child have to start from scratch? Is There a Missing Link? The story of human evolution is not complete. In addition to hoaxes such as "Piltdown Man" and extraordinary finds such as "Lucy," many puzzles remain. What, in the end, do we mean by a "missing link"?

This book was released on 2008-05-02 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: An in-depth look at the theories behind the most intriguing puzzles in physics, chemistry, biology, earth science, and astronomy In The Five Biggest Ideas in Science, authors Arthur W. Wiggins and Charles M. Wynn discussed science's most important current ideas. Now, they tackle the questions that science has been unable to answer-so far. Choosing one unsolved problem from each discipline, they explore the current scientific thinking behind these questions: How are particle masses determined? How did simple atoms first combine to form complex molecules? What role does the genome play in the development of life? Why is it so difficult to predict the weather? And what is the future of the universe? Featuring cartoons by Sidney Harris, the book includes discussions of recent theories such as the God particle, string theory, "brane" theories, and the Theory of Everything and also explores other science questions. Arthur W. Wiggins (Farmington Hills, MI) is a Professor of Physics at Oakland Community College in Michigan. Charles M. Wynn (Willimantic, CT) is a Professor of Chemistry at Eastern Connecticut State College. They collaborated on The Five Biggest Ideas in Science (0-471-13812-6).

Available in PDF, EPUB and Kindle. Book excerpt: Understanding how simple molecules have given rise to the complex biochemical systems and processes of contemporary biology is widely regarded as one of chemistry’s great unsolved questions. There are numerous theories as to the origins of life, the majority of which draw on the idea that DNA and nucleic acids are the central dogma of biology. The Singularity of Nature: A Convergence of Biology, Chemistry and Physics takes a systems-based approach to the origin and evolution of complex life. Readers will gain a novel understanding of physiologic evolution and the limits to our current understanding: why biology remains descriptive and non-predictive, as well as offering new opportunities for understanding relationships between physics and biology in the origins of biological life at the cellular-molecular level.

Download or read book Calculating the Secrets of Life written by National Research Council and published by National Academies Press. This book was released on 1995-04-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: As researchers have pursued biology's secrets to the molecular level, mathematical and computer sciences have played an increasingly important roleâ€"in genome mapping, population genetics, and even the controversial search for "Eve," hypothetical mother of the human race. In this first-ever survey of the partnership between the two fields, leading experts look at how mathematical research and methods have made possible important discoveries in biology. The volume explores how differential geometry, topology, and differential mechanics have allowed researchers to "wind" and "unwind" DNA's double helix to understand the phenomenon of supercoiling. It explains how mathematical tools are revealing the workings of enzymes and proteins. And it describes how mathematicians are detecting echoes from the origin of life by applying stochastic and statistical theory to the study of DNA sequences. This informative and motivational book will be of interest to researchers, research administrators, and educators and students in mathematics, computer sciences, and biology.

Download or read book Life from an RNA World written by Michael Yarus and published by Harvard University Press. This book was released on 2010 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: A majority of evolutionary biologists believe that we now can envision our biological predecessors--not the first, but nearly the first, living beings on Earth. This book is about these vanished forebears. The era between the first rudimentary life on Earth and the appearance of more complex beings is called the RNA world. It is RNA (ribonucleic acid) long believed to be a mere biologic copier and messenger, that offers a glimpse into our ancient predecessors. To describe early RNA creatures, here called "ribocytes" or RNA cells, the author uses basics of molecular biology. He reviews our current understanding of the tree of life, examines the structure of RNA itself, explains the operation of the genetic code, and more. Courting controversy among those who question the role of ribocytes -- citing the chemical fragility of RNA and the uncertainty about the origin of an RNA synthetic apparatus -- he offers a vision of early life on Earth.
