The Origin of Species by DNA Coding


Book Description

Who are we? Where are we from? These questions have troubled people for centuries. The textbooks have long taught us that human beings evolved from anthropoid apes. Today, a new science, molecular anthropology, tells us this: 7 billion human beings in the world share a common grand, grand…father, the Y-chromosome Adam, and share a common grand, grand…mother, the Mitochondrial Eve. After reading information in this book, you will be convinced that human beings could not be the result of evolution, sudden mutation, or in any way related to the anthropoid apes.







Genetics and the Extinction of Species


Book Description

Darwin's Origin of Species and Dobzhansky's Genetics and the Origin of Species have been the cornerstones of modern evolutionary and population genetic theory for the past hundred years, but in the twenty-first century, biologists will face graver problems of extinction. In this collection, a team of leading biologists demonstrates why the burgeoning field of conservation biology must continue to rely on the insights of population genetics if we are to preserve the diversity of living species. Technological and theoretical developments throughout the 1990s have allowed for important new insights into how populations have evolved in response to past selection pressures, while providing a broad new understanding of the genetic structure of natural populations. The authors explore these advances and argue for the applicability of new genetic methods in conservation biology. The volume covers such topics as the reasons for extinctions, the best ways to measure biodiversity, and the benefits and drawbacks of policies like captive breeding. Genetics and the Extinction of Species is a rich source of information for biologists and policymakers who want to learn more about the host of tools, theories, and approaches available for conserving biodiversity. In addition to the editors, the contributors to the volume are William Amos, Rebecca Cann, Kathryn Rodriguez-Clark, Leslie Douglas, Leonard Freed, Paul Harvey, Kent Holsinger, Russell Lande, and Helen Steers.




Mapping and Sequencing the Human Genome


Book Description

There is growing enthusiasm in the scientific community about the prospect of mapping and sequencing the human genome, a monumental project that will have far-reaching consequences for medicine, biology, technology, and other fields. But how will such an effort be organized and funded? How will we develop the new technologies that are needed? What new legal, social, and ethical questions will be raised? Mapping and Sequencing the Human Genome is a blueprint for this proposed project. The authors offer a highly readable explanation of the technical aspects of genetic mapping and sequencing, and they recommend specific interim and long-range research goals, organizational strategies, and funding levels. They also outline some of the legal and social questions that might arise and urge their early consideration by policymakers.




The Search for Life's Origins


Book Description

The field of planetary biology and chemical evolution draws together experts in astronomy, paleobiology, biochemistry, and space science who work together to understand the evolution of living systems. This field has made exciting discoveries that shed light on how organic compounds came together to form self-replicating molecules-the origin of life. This volume updates that progress and offers recommendations on research programs-including an ambitious effort centered on Mars-to advance the field over the next 10 to 15 years. The book presents a wide range of data and research results on these and other issues: The biogenic elements and their interaction in the interstellar clouds and in solar nebulae. Early planetary environments and the conditions that lead to the origin of life. The evolution of cellular and multicellular life. The search for life outside the solar system. This volume will become required reading for anyone involved in the search for life's beginnings-including exobiologists, geoscientists, planetary scientists, and U.S. space and science policymakers.




Biology for AP ® Courses


Book Description

Biology for AP® courses covers the scope and sequence requirements of a typical two-semester Advanced Placement® biology course. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology for AP® Courses was designed to meet and exceed the requirements of the College Board’s AP® Biology framework while allowing significant flexibility for instructors. Each section of the book includes an introduction based on the AP® curriculum and includes rich features that engage students in scientific practice and AP® test preparation; it also highlights careers and research opportunities in biological sciences.







Evolution of the Genetic Code


Book Description

The genetic code was deciphered experimentally around 1966 and for a number of years scientists considered it to be "universal" for all forms of life. In 1981 researchers shocked the scientific community with the discovery that the code differed in mitochondria and certain other organisms, evidence that the genetic code was still evolving. This book discusses the distribution and origin of the non-universal codes and examines the possible mechanisms of code changes, making it essential reading for all those interested in evolutionary genetics.




Life's Greatest Secret


Book Description

Everyone has heard of the story of DNA as the story of Watson and Crick and Rosalind Franklin, but knowing the structure of DNA was only a part of a greater struggle to understand life's secrets. Life's Greatest Secret is the story of the discovery and cracking of the genetic code, the thing that ultimately enables a spiraling molecule to give rise to the life that exists all around us. This great scientific breakthrough has had farreaching consequences for how we understand ourselves and our place in the natural world, and for how we might take control of our (and life's) future. Life's Greatest Secret mixes remarkable insights, theoretical dead-ends, and ingenious experiments with the swift pace of a thriller. From New York to Paris, Cambridge, Massachusetts, to Cambridge, England, and London to Moscow, the greatest discovery of twentieth-century biology was truly a global feat. Biologist and historian of science Matthew Cobb gives the full and rich account of the cooperation and competition between the eccentric characters -- mathematicians, physicists, information theorists, and biologists -- who contributed to this revolutionary new science. And, while every new discovery was a leap forward for science, Cobb shows how every new answer inevitably led to new questions that were at least as difficult to answer: just ask anyone who had hoped that the successful completion of the Human Genome Project was going to truly yield the book of life, or that a better understanding of epigenetics or "junk DNA" was going to be the final piece of the puzzle. But the setbacks and unexpected discoveries are what make the science exciting, and it is Matthew Cobb's telling that makes them worth reading. This is a riveting story of humans exploring what it is that makes us human and how the world works, and it is essential reading for anyone who'd like to explore those questions for themselves.
