The Future Of Human Heredity

Evolutionary selection has been radically relaxed in the human species as a result of the development of civilization, science in general, and medicine in particular. While these advances have hugely benefited current populations, they have to a significant degree released the species from the biological process which created it and maintains its viability. Formerly, natural selection took place largely as a result of differential mortality, but now that most people survive well beyond their child bearing years, selection is determined largely by differential fertility. Aside from genetic illnesses, this new selection is also characterized by a negative correlation between fertility and intelligencethe core of eugenic concern for over a century. Eugenics views itself as the fourth leg of the chair of civilization, the other three being a) a thrifty expenditure of natural resources, b) mitigation of environmental pollution, and c) maintenance of a human population not exceeding the planets carrying capacity. Eugenics, which can be thought of as human ecology, is thus part and parcel of the environmental movement. Humanity is defined, not as the totality of the currently living population, but as the number of people who will potentially ever live. This is a book about the struggle for human rights and parental responsibility.

Writing for the lay reader, Stock, the director of the Program on Medicine, Technology, and Society at the School of Public Health at UCLA, discusses the science, potential impact, and many controversies surrounding the development of germline engineering, which involves selectively altering human g

Forget worries about cloning people. In the future, technological advances will bring far more meaningful and controversial changes to our offspring. As scientists rapidly improve their ability to identify, screen and manipulate genes, people will want to protect their future children from diseases, help them live longer and even influence their looks and their abilities. Stock, an expert on the implications of recent advances in reproductive biology, clearly shows that neither governments, nor religious groups will be able to stop the coming trend of choosing an embryo's genes, and that there is little point in even trying.

An interdisciplinary exploration of whether modern genetics and bioengineering are leading us to a posthuman future.

"A gifted and thoughtful writer, Metzl brings us to the frontiers of biology and technology, and reveals a world full of promise and peril." — Siddhartha Mukherjee MD, New York Times bestselling author of The Emperor of All Maladies and The Gene A groundbreaking exploration of genetic engineering and its impact on the future of our species from leading geopolitical expert and technology futurist, Jamie Metzl. At the dawn of the genetics revolution, our DNA is becoming as readable, writable, and hackable as our information technology. But as humanity starts retooling our own genetic code, the choices we make today will be the difference between realizing breathtaking advances in human well-being and descending into a dangerous and potentially deadly genetic arms race. Enter the laboratories where scientists are turning science fiction into reality. In this captivating and thought-provoking nonfiction science book, Jamie Metzl delves into the ethical, scientific, political, and technological dimensions of genetic engineering, and shares how it will shape the course of human evolution. Cutting-edge insights into the field of genetic engineering and its implications for humanity's future Explores the transformative power of genetic technologies and their potential to reshape human life Examines the ethical considerations surrounding genetic engineering and the choices we face as a species Engaging narrative that delves into the scientific breakthroughs and real-world applications of genetic technologies Provides a balanced perspective on the promises and risks associated with genetic engineering Raises thought-provoking questions about the future of reproduction, human health, and our relationship with nature Drawing on his extensive background in genetics, national security, and foreign policy, Metzl paints a vivid picture of a world where advancements in technology empower us to take control of our own evolution, but also cautions against the pitfalls and ethical dilemmas that could arise if not properly managed. Hacking Darwin is a must-read for anyone interested in the intersection of science, technology, and humanity's future.

Advances in genetic technology in general and medical genetics in particular will enable us to intervene in the process of human biological development which extends from zygotes and embryos to people. This will allow us to control to a great extent the identities and the length and quality of the lives of people who already exist, as well as those we bring into existence in the near and distant future. Genes and Future People explores two general philosophical questions, one metaphysical, the other moral: (1) How do genes, and different forms of genetic intervention (gene therapy, genetic enhancement, presymptomatic genetic testing of adults, genetic testing of preimplantation embryos), affect the identities of the people who already exist and those we bring into existence? and (2) How do these interventions benefit or harm the people we cause to exist in the near future and those who will exist in the distant future by satisfying or defeating their interest in having reasonably long and disease-free lives?Genes and Future People begins by explaining the connection between genes and disease, placing genetic within a framework of evolutionary biology. It then discusses such topics as how genes and genetic intervention influence personal identity, what genetic testing of individuals and the knowledge resulting from it entails about responsibility to others who may be at risk, as well as how gene therapy and genetic enhancement can affect the identities of people and benefit or harm them. Furthermore, it discusses various moral aspects of cloning human beings and body parts. Finally, it explores the metaphysical and moral implications of genetic manipulation of the mechanisms of aging to extend the human life span.The aim Genes and Future People is to move philosophers, bioethicists, and readers in general to reflect on the extent to which genes determine whether we are healthy or diseased, our identities as persons, the quality of our lives, and our moral obligations to future generations of people.

Genetics and Evolution is a six-volume set that explores the principal fields of modern molecular biology from their origins to the most recent discoveries and technological breakthroughs. A century and a half after evolutionary and genetic science began, biology and medicine are coming together to form a powerful new view of the living world that is having a dramatic effect on human health and society. As well as introducing the basic terms and concepts, the set examines the most significant social and ethical issues surrounding current biomedical research and serves as a valuable guide to the world that science is creating. Human Genetics: Race, Population, and Disease offers a fascinating introduction to the field of human genetics-from its historical roots to recent discoveries in and out of the laboratory-focusing on its applications to medicine, forensic science, and genetic counseling. The book looks at human beings as individuals who arise through an interaction of genes and the environment and explores the rich variety within the human species, including the differences between individuals and groups, the genetic meaning of race, and how genes influence behavior and society. The volume includes information on the application of genetics to solve crime diagnosis and genetic counseling evolutionary psychology the genetics of cancer the "history" of the human genome human diversity modern genetics and human beings stem cell research The book contains more than 30 color photographs and four-color line illustrations, sidebars, a chronology, a glossary, a detailed list of print and Internet resources, and an index. Genetics and Evolution is essential for high school students, teachers, and general readers who wish to learn about the "revolution" of evolutionary research and discovery.
