In The Disappearing Spoon, bestselling author Sam Kean unlocked the mysteries of the periodic table. In THE VIOLINIST'S THUMB, he explores the wonders of the magical building block of life: DNA.
There are genes to explain crazy cat ladies, why other people have no fingerprints, and why some people survive nuclear bombs. Genes illuminate everything from JFK's bronze skin (it wasn't a tan) to Einstein's genius. They prove that Neanderthals and humans bred thousands of years more recently than any of us would feel comfortable thinking. They can even allow some people, because of the exceptional flexibility of their thumbs and fingers, to become truly singular violinists.
Kean's vibrant storytelling once again makes science entertaining, explaining human history and whimsy while showing how DNA will influence our species' future.
FINANCIAL TIMES (LONDON)
World renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a ROOTS for the human species, a lucid and riveting account of how humans got to be the way we are. It shows with humor and drama that many of our key traits--self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics--are rooted in the deep past, and illuminated by our kinship with other animals. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, SHADOWS OF FORGOTTEN ANCESTORS is a triumph of popular science.

Why are rates of conditions like autism, asthma, obesity, and allergies exploding at an unprecedented pace? Why are humans living longer, getting smarter, and having far fewer kids? How might your lifestyle affect your unborn children and grandchildren? How will gene-editing technologies like CRISPR steer the course of human evolution? If Darwin were alive today, how would he explain this new world? Could our progeny eventually become a different species—or several?
In Evolving Ourselves, futurist Juan Enriquez and scientist Steve Gullans conduct a sweeping tour of how humans are changing the course of evolution—sometimes intentionally, sometimes not. For example:
• Globally, rates of obesity in humans nearly doubled between 1980 and 2014. What’s more, there’s evidence that other species, from pasture-fed horses to lab animals to house cats, are also getting fatter.
• As reported by U.S. government agencies, the rate of autism rose by 131 percent from 2001 to 2010, an increase that cannot be attributed simply to increases in diagnosis rates.
• Three hundred years ago, almost no one with a serious nut allergy lived long enough to reproduce. Today, despite an environment in which food allergies have increased by 50 percent in just over a decade, 17 million Americans who suffer from food allergies survive, thrive, and pass their genes and behaviors on to the next generation.
• In the pre-Twinkie era, early humans had quite healthy mouths. As we began cooking, bathing, and using antibiotics, the bacteria in our bodies changed dramatically and became far less diverse. Today the consequences are evident not only in our teeth but throughout our bodies and minds.
Though these harbingers of change are deeply unsettling, the authors argue that we are also in an epoch of tremendous opportunity. New advances in biotechnology help us mitigate the cruel forces of natural selection, from saving prematurely born babies to gene therapies for sickle cell anemia and other conditions. As technology like CRISPR enables us to take control of our genes, we will be able to alter our own species and many others—a good thing, given that our eventual survival will require space travel and colonization, enabled by a fundamental redesign of our bodies.
Future humans could become great caretakers of the planet, as well as a more diverse, more resilient, gentler, and more intelligent species—but only if we make the right choices now.
Intelligent, provocative, and optimistic, Evolving Ourselves is the ultimate guide to the next phase of life on Earth.

But what does it mean?
Arguably the most significant scientific discovery of the new century, the mapping of the twenty-three pairs of chromosomes that make up the human genome raises almost as many questions as it answers. Questions that will profoundly impact the way we think about disease, about longevity, and about free will. Questions that will affect the rest of your life.
Genome offers extraordinary insight into the ramifications of this incredible breakthrough. By picking one newly discovered gene from each pair of chromosomes and telling its story, Matt Ridley recounts the history of our species and its ancestors from the dawn of life to the brink of future medicine. From Huntington's disease to cancer, from the applications of gene therapy to the horrors of eugenics, Matt Ridley probes the scientific, philosophical, and moral issues arising as a result of the mapping of the genome. It will help you understand what this scientific milestone means for you, for your children, and for humankind.
“A smart and important book.”—Gretchen Reynolds, author of The First 20 Minutes

Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies and becoming a healthy human is impossible without them.
In this riveting, shocking, and beautifully written book, biologist Alanna Collen draws on the latest scientific research to show how our personal colony of microbes influences our weight, our immune system, our mental health, and even our choice of partner. She argues that so many of our modern diseases—obesity, autism, mental illness, digestive disorders, allergies, autoimmunity afflictions, and even cancer—have their root in our failure to cherish our most fundamental and enduring relationship: that with our personal colony of microbes.
Many of the questions about modern diseases left unanswered by the Human Genome Project are illuminated by this new science. And the good news is that unlike our human cells, we can change our microbes for the better. Collen's book is a revelatory and indispensable guide. It is science writing at its most relevant: life—and your body—will never seem the same again.
Stepping effortlessly from myth to cutting-edge science, Mutants gives a brilliant narrative account of our genetic code and the captivating people whose bodies have revealed it—a French convent girl who found herself changing sex at puberty; children who, echoing Homer’s Cyclops, are born with a single eye in the middle of their foreheads; a village of long-lived Croatian dwarves; one family, whose bodies were entirely covered with hair, was kept at the Burmese royal court for four generations and gave Darwin one of his keenest insights into heredity. This elegant, humane, and engaging book “captures what we know of the development of what makes us human” (Nature).
A leading epigenetics researcher, Nessa Carey also connects the field’s arguments to such diverse phenomena as how ants and queen bees control their colonies, why tortoiseshell cats are always female, why some plants need cold weather before they can flower, and how we age and develop disease. She concludes with future directions for research and the ability for epigenetics to improve human health and well-being. Published in the United Kingdom in 2011 and widely praised on both sides of the Atlantic, this new book is sure to become a classic in modern biology.
What can we learn from the genes of our closest evolutionary relatives? Neanderthal Man tells the story of geneticist Svante Pääbo's mission to answer that question, beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in his sequencing of the Neanderthal genome in 2009. From Pääbo, we learn how Neanderthal genes offer a unique window into the lives of our hominin relatives and may hold the key to unlocking the mystery of why humans survived while Neanderthals went extinct. Drawing on genetic and fossil clues, Pääbo explores what is known about the origin of modern humans and their relationship to the Neanderthals and describes the fierce debate surrounding the nature of the two species' interactions.
A riveting story about a visionary researcher and the nature of scientific inquiry, Neanderthal Man offers rich insight into the fundamental question of who we are.
Eight-year-old Corey Haas was nearly blind from a hereditary disorder when his sight was restored through a delicate procedure that made medical history. Like something from a science fiction novel, doctors carefully injected viruses bearing healing genes into the DNA of Corey's eyes—a few days later, Corey could see, his sight restored by gene therapy.
THE FOREVER FIX is the first book to tell the fascinating story of gene therapy: how it works, the science behind it, how patients (mostly children) have been helped and harmed, and how scientists learned from each trial to get one step closer to its immense promise, the promise of a "forever fix," - a cure that, by fixing problems at their genetic root, does not need further surgery or medication.
Told through the voices of the children and families who have been the inspiration, experimental subjects, and successes of genetic science, THE FOREVER FIX is compelling and engaging narrative science that tells explores the future of medicine as well as the families and scientists who are breaking new ground every day.
By identifying the structure of DNA, the molecule of life, Francis Crick and James Watson revolutionized biochemistry and won themselves a Nobel Prize. At the time, Watson was only twenty-four, a young scientist hungry to make his mark. His uncompromisingly honest account of the heady days of their thrilling sprint against other world-class researchers to solve one of science’s greatest mysteries gives a dazzlingly clear picture of a world of brilliant scientists with great gifts, very human ambitions, and bitter rivalries.
With humility unspoiled by false modesty, Watson relates his and Crick’s desperate efforts to beat Linus Pauling to the Holy Grail of life sciences, the identification of the basic building block of life. Never has a scientist been so truthful in capturing in words the flavor of his work.

The common ancestry of all humanity
The role of genes in sickness and health
Debates over the use of genetic technology
Written in an engaging, narrative manner, this concise introduction is an ideal starting point for anyone who wants to know more about genes, DNA, and the genetic ties that bind us all.
The most disruptive force on the planet resides in DNA. Biotech companies and academic researchers are just beginning to unlock the potential of piecing together life from scratch. Champions of synthetic biology believe that turning genetic code into Lego-like blocks to build never-before-seen organisms could solve the thorniest challenges in medicine, energy, and environmental protection. But as the hackers who cracked open the potential of the personal computer and the Internet proved, the most revolutionary discoveries often emerge from out-of-the-way places, forged by brilliant outsiders with few resources besides boundless energy and great ideas.
In Biopunk, Marcus Wohlsen chronicles a growing community of DIY scientists working outside the walls of corporations and universities who are committed to democratizing DNA the way the Internet did information. The "biohacking" movement, now in its early, heady days, aims to unleash an outbreak of genetically modified innovation by making the tools and techniques of biotechnology accessible to everyone. Borrowing their idealism from the worlds of open-source software, artisinal food, Internet startups, and the Peace Corps, biopunks are devoted advocates for open-sourcing the basic code of life. They believe in the power of individuals with access to DNA to solve the world's biggest problems.
You'll meet a new breed of hackers who aren't afraid to get their hands wet, from entrepreneurs who aim to bring DNA-based medical tools to the poorest of the poor to a curious tinkerer who believes a tub of yogurt and a jellyfish gene could protect the world's food supply. These biohackers include:
-A duo who started a cancer drug company in their kitchen
-A team who built an open-source DNA copy machine
-A woman who developed a genetic test in her apartment for a deadly disease that had stricken her family
Along with the potential of citizen science to bring about disruptive change, Wohlsen explores the risks of DIY bioterrorism, the possibility of genetic engineering experiments gone awry, and whether the ability to design life from scratch on a laptop might come sooner than we think.
Conventional wisdom dictates that our genetic destiny is fixed at conception. But Dr. Moalem's groundbreaking book shows us that the human genome is far more fluid and fascinating than your ninth grade biology teacher ever imagined. By bringing us to the bedside of his unique and complex patients, he masterfully demonstrates what rare genetic conditions can teach us all about our own health and well-being.
In the brave new world we're rapidly rocketing into, genetic knowledge has become absolutely crucial. INHERITANCE provides an indispensable roadmap for this journey by teaching you:
-Why you may have recovered from the psychological trauma caused by childhood bullying-but your genes may remain scarred for life.
-How fructose is the sugar that makes fruits sweet-but if you have certain genes, consuming it can buy you a one-way trip to the coroner's office.
-Why ingesting common painkillers is like dosing yourself repeatedly with morphine-if you have a certain set of genes.
-How insurance companies legally use your genetic data to predict the risk of disability for you and your children-and how that impacts the coverage decisions they make for your family.
-How to have the single most important conversation with your doctor-one that can save your life.
-Why people with rare genetic conditions hold the keys to medical problems affecting millions.
In this trailblazing book, Dr. Moalem employs his wide-ranging and entertaining interdisciplinary approach to science and medicine-- explaining how art, history, superheroes, sex workers, and sports stars all help us understand the impact of our lives on our genes, and our genes on our lives. INHERITANCE will profoundly alter how you view your genes, your health--and your life.
Science journalist Jessica Wapner reconstructs more than forty years of crucial breakthroughs, clearly explains the science behind them, and pays tribute—with extensive original reporting, including more than thirty-five interviews—to the dozens of researchers, doctors, and patients with a direct role in this inspirational story. Their curiosity and determination would ultimately lead to a lifesaving treatment unlike anything before it.
The Philadelphia Chromosome chronicles the remarkable change of fortune for the more than 70,000 people worldwide who are diagnosed with CML each year. It is a celebration of a rare triumph in the battle against cancer and a blueprint for future research, as doctors and scientists race to uncover and treat the genetic roots of a wide range of cancers.
On May 20, 2010, headlines around the world announced one of the most extraordinary accomplishments in modern science: the creation of the world’s first synthetic lifeform. In Life at the Speed of Light, scientist J. Craig Venter, best known for sequencing the human genome, shares the dramatic account of how he led a team of researchers in this pioneering effort in synthetic genomics—and how that work will have a profound impact on our existence in the years to come. This is a fascinating and authoritative study that provides readers an opportunity to ponder afresh the age-old question “What is life?” at the dawn of a new era of biological engineering.
In Regenesis, Harvard biologist George Church and science writer Ed Regis explore the possibilities—and perils—of the emerging field of synthetic biology. Synthetic biology, in which living organisms are selectively altered by modifying substantial portions of their genomes, allows for the creation of entirely new species of organisms. These technologies—far from the out-of-control nightmare depicted in science fiction—have the power to improve human and animal health, increase our intelligence, enhance our memory, and even extend our life span. A breathtaking look at the potential of this world-changing technology, Regenesis is nothing less than a guide to the future of life.
Brenda Maddox tells a powerful story of a remarkably single-minded, forthright, and tempestuous young woman who, at the age of fifteen, decided she was going to be a scientist, but who was airbrushed out of the greatest scientific discovery of the twentieth century.
As the old adage goes, where there's smoke, there's fire. Where there is effect, there must be cause. The planet Neptune was found in 1846 because the mathematics of Newton's laws, when applied to the orbit of Uranus, said some massive body had to be there. Astronomers eventually found it, using the best telescopes available to peer into the sky. This same logic is applied to the search for the Higgs boson. One consequence of the prevailing theory of physics, called the Standard Model, is that there has to be some field that gives particles their particular masses. With that there has to be a corresponding particle, made by creating waves in the field, and this is the Higgs boson, the so-called God particle. This book chronicles the ongoing search – and demonstrates the power of a good theory. Based on the Standard Model, physicists believed something had to be there, but it wasn't until the Large Hadron Collider was built that anyone could see evidence of the Higgs – and finally in July 2012, they did. A Higgs-like particle was found near the energies scientists expected to find it. Now, armed with better evidence and better questions, the scientific process continues. This book gathers the best reporting and analysis from Scientific American to explain that process – the theories, the search, the ongoing questions. In essence, everything you need to know to separate Higgs from hype.
Fewer ideas have been more toxic or harmful than the idea of the biological reality of race, and with it the idea that humans of different races are biologically different from one another. For this understandable reason, the idea has been banished from polite academic conversation. Arguing that race is more than just a social construct can get a scholar run out of town, or at least off campus, on a rail. Human evolution, the consensus view insists, ended in prehistory.
Inconveniently, as Nicholas Wade argues in A Troublesome Inheritance, the consensus view cannot be right. And in fact, we know that populations have changed in the past few thousand years—to be lactose tolerant, for example, and to survive at high altitudes. Race is not a bright-line distinction; by definition it means that the more human populations are kept apart, the more they evolve their own distinct traits under the selective pressure known as Darwinian evolution. For many thousands of years, most human populations stayed where they were and grew distinct, not just in outward appearance but in deeper senses as well.
Wade, the longtime journalist covering genetic advances for The New York Times, draws widely on the work of scientists who have made crucial breakthroughs in establishing the reality of recent human evolution. The most provocative claims in this book involve the genetic basis of human social habits. What we might call middle-class social traits—thrift, docility, nonviolence—have been slowly but surely inculcated genetically within agrarian societies, Wade argues. These “values” obviously had a strong cultural component, but Wade points to evidence that agrarian societies evolved away from hunter-gatherer societies in some crucial respects. Also controversial are his findings regarding the genetic basis of traits we associate with intelligence, such as literacy and numeracy, in certain ethnic populations, including the Chinese and Ashkenazi Jews.
Wade believes deeply in the fundamental equality of all human peoples. He also believes that science is best served by pursuing the truth without fear, and if his mission to arrive at a coherent summa of what the new genetic science does and does not tell us about race and human history leads straight into a minefield, then so be it. This will not be the last word on the subject, but it will begin a powerful and overdue conversation.

Darwin’s theory of natural selection explains how useful adaptations are preserved over time. But the biggest mystery about evolution eluded him. As genetics pioneer Hugo de Vries put it, “natural selection may explain the survival of the fittest, but it cannot explain the arrival of the fittest.”
Can random mutations over a mere 3.8 billion years really be responsible for wings, eyeballs, knees, camouflage, lactose digestion, photosynthesis, and the rest of nature’s creative marvels? And if the answer is no, what is the mechanism that explains evolution’s speed and efficiency?
In Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over fifteen years of research to present the missing piece in Darwin's theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take.
Consider the Arctic cod, a fish that lives and thrives within six degrees of the North Pole, in waters that regularly fall below 0 degrees. At that temperature, the internal fluids of most organisms turn into ice crystals. And yet, the arctic cod survives by producing proteins that lower the freezing temperature of its body fluids, much like antifreeze does for a car’s engine coolant. The invention of those proteins is an archetypal example of nature’s enormous powers of creativity.
Meticulously researched, carefully argued, evocatively written, and full of fascinating examples from the animal kingdom, Arrival of the Fittest offers up the final puzzle piece in the mystery of life’s rich diversity.
Examining the hidden secrets of human evolution in our genetic code, Spencer Wells reveals how developments in the revolutionary science of population genetics have made it possible to create a family tree for the whole of humanity. Replete with marvelous anecdotes and remarkable information, from the truth about the real Adam and Eve to the way differing racial types emerged, The Journey of Man is an enthralling, epic tour through the history and development of early humankind.
The "study "of human biology is different from the study of the biology of other species. In the simplest terms, people's lives and welfare may depend upon it, in a sense that they may not depend on the study of other scientific subjects. Where science is used to validate ideas--four out of five scientists preferring a brand of cigarettes or toothpaste--there is a tendency to accept the judgment as authoritative without asking the kinds of questions we might ask of other citizens' pronouncements.
In "Human Biodiversity, "Marks has attempted to distill from a centuries-long debate what has been learned and remains to be learned about the biological differences within and among human groups. His is the first such attempt by an anthropologist in years, for genetics has undermined the fundamental assumptions of racial taxonomy. The history of those assumptions from Linnaeus to the recent past--the history of other, more useful assumptions that derive from Buffon and have reemerged to account for genetic variation--are the poles of Marks's exploration.
The book covers topics from introductory level right up to cutting edge research. High-profile cases are addressed throughout the text, near the sections dealing with the science or issues behind these cases. Ten new chapters have been added to accommodate the explosion of new information since the turn of the century. These additional chapters cover statistical genetic analysis of DNA data, an emerging field of interest to DNA research. Several chapters on statistical analysis of short tandem repeat (STR) typing data have been contributed by Dr. George Carmody, a well-respected professor in forensic genetics. Specific examples make the concepts of population genetics more understandable.
This book will be of interest to researchers and practitioners in forensic DNA analysis, forensic scientists, population geneticists, military and private and public forensic laboratories (for identifying individuals through remains), and students of forensic science.

Using DNA collected from remains as a genetic blueprint, scientists aim to engineer extinct traits--traits that evolved by natural selection over thousands of years--into living organisms. But rather than viewing de-extinction as a way to restore one particular species, Shapiro argues that the overarching goal should be the revitalization and stabilization of contemporary ecosystems. For example, elephants with genes modified to express mammoth traits could expand into the Arctic, re-establishing lost productivity to the tundra ecosystem.
Looking at the very real and compelling science behind an idea once seen as science fiction, How to Clone a Mammoth demonstrates how de-extinction will redefine conservation's future.

Scientists have long believed that the “great leap forward” that occurred some 40,000 to 50,000 years ago in Europe marked end of significant biological evolution in humans. In this stunningly original account of our evolutionary history, top scholars Gregory Cochran and Henry Harpending reject this conventional wisdom and reveal that the human species has undergone a storm of genetic change much more recently. Human evolution in fact accelerated after civilization arose, they contend, and these ongoing changes have played a pivotal role in human history. They argue that biology explains the expansion of the Indo-Europeans, the European conquest of the Americas, and European Jews' rise to intellectual prominence. In each of these cases, the key was recent genetic change: adult milk tolerance in the early Indo-Europeans that allowed for a new way of life, increased disease resistance among the Europeans settling America, and new versions of neurological genes among European Jews.
Ranging across subjects as diverse as human domestication, Neanderthal hybridization, and IQ tests, Cochran and Harpending's analysis demonstrates convincingly that human genetics have changed and can continue to change much more rapidly than scientists have previously believed. A provocative and fascinating new look at human evolution that turns conventional wisdom on its head, The 10,000 Year Explosion reveals the ongoing interplay between culture and biology in the making of the human race.
With The Longevity Seekers, science writer Ted Anton takes readers inside this tale that began with worms and branched out to snare innovative minds from California to Crete, investments from big biotech, and endorsements from TV personalities like Oprah and Dr. Oz. Some of the research was remarkable, such as the discovery of an enzyme in humans that stops cells from aging. And some, like an oft-cited study touting the compound resveratrol, found in red wine—proved highly controversial, igniting a science war over truth, credit, and potential profit. As the pace of discovery accelerated, so too did powerful personal rivalries and public fascination, driven by the hope that a longer, healthier life was right around the corner. Anton has spent years interviewing and working with the scientists at the frontier of longevity science, and this book offers a behind-the-scenes look at the state-of-the-art research and the impact it might have on global public health, society, and even our friends and family.
With spectacular science and an unforgettable cast of characters, The Longevity Seekers has all the elements of a great story and sheds light on discoveriesthat could fundamentally reshape human life.

According to American Demographics, 113 million Americans have begun to trace their roots, making genealogy the second most popular hobby in the country (after gardening). Enthusiasts clamor for new information from dozens of subscription-based websites, email newsletters, and magazines devoted to the subject. For these eager roots-seekers looking to take their searches to the next level, DNA testing is the answer.
After a brief introduction to genealogy and genetics fundamentals, the authors explain the types of available testing, what kind of information the tests can provide, how to interpret the results, and how the tests work (it doesn't involve digging up your dead relatives). It's in expensive, easy to do, and the results are accurate: It's as simple as swabbing the inside of your cheek and popping a sample in the mail.
There are several types of genealogical scenarios you can pursue, such as:Family lore has it that a branch of our family emigrated to Argentina and now I've found some people there with our name. Can testing tell us whether we're from the same family?My mother was adopted and doesn't know her ethnicity. Are there any tests available to help her learn about her heritage?I just discovered someone else with my highly unusual surname. How can we find out if we have a common ancestor?
The authors reveal exactly what is--and what is not--possible with genetic testing. They include case studies of both famous historial mysteries and examples of ordinary folks whose exploration of genetic genealogy has enabled them to trace their roots.
Aging, cancer, stem cells, cloning - the themes of Merchants of Immortality are the stuff of today's headlines, yet they reflect some of humankind's most ancient hopes and fears. Stephen S. Hall delves behind the headlines to reveal just how close scientists are to fulfilling hopes of longer, healthier lives. Merchants of Immortality tackles profound social questions: How close are we to cloning humans? Can stem cell therapies tame illnesses such as heart attacks, Parkinson's disease, and diabetes? How long might our children live?
Hall's account of life-extension research is as dramatic as it is authoritative. The story follows a close-knit but fractious band of scientists and entrepreneurs who work in the shadowy area between profit and the public good. Hall tracks the science of aging back to its father figure, the iconoclastic Leonard Hayflick, who was the first to show that cells age and whose epic legal battles with the federal government cleared the path for today's biotech visionaries. Chief among those is the charismatic Michael West, a former creationist who founded the first biotech company devoted to aging research. West has won both ardent admirers and committed foes in his relentless quest to promote stem cells, therapeutic cloning, and other technologies of "practical immortality." Merchants of Immortality breathes scintillating life into the most momentous science of our day, assesses the political and bioethical controversies it has spawned, and explores its potentially dramatic effect on the length and quality of our lives.
Vegan, low fat, low carb, slow carb: Every diet seems to promise a one-size-fits-all solution to health. But they ignore the diversity of human genes and how they interact with what we eat.
In Food, Genes, and Culture, renowned ethnobotanist Gary Nabhan shows why the perfect diet for one person could be disastrous for another. If your ancestors were herders in Northern Europe, milk might well provide you with important nutrients, whereas if you're Native American, you have a higher likelihood of lactose intolerance. If your roots lie in the Greek islands, the acclaimed Mediterranean diet might save your heart; if not, all that olive oil could just give you stomach cramps.
Nabhan traces food traditions around the world, from Bali to Mexico, uncovering the links between ancestry and individual responses to food. The implications go well beyond personal taste. Today's widespread mismatch between diet and genes is leading to serious health conditions, including a dramatic growth over the last 50 years in auto-immune and inflammatory diseases.
Readers will not only learn why diabetes is running rampant among indigenous peoples and heart disease has risen among those of northern European descent, but may find the path to their own perfect diet.
Maxwell J. Mehlman considers the promises and perils of using genetic engineering in an effort to direct the future course of human evolution. He addresses scientific and ethical issues without choosing sides in the dispute between transhumanists and their challengers. However, Transhumanist Dreams and Dystopian Nightmares reveals that radical forms of genetic engineering could become a reality much sooner than many people think, and that we need to encourage risk-management efforts.
Whether scientists are dubious or optimistic about the prospects for directed evolution, they tend to agree on two things. First, however long it takes to perfect the necessary technology, it is inevitable that humans will attempt to control their evolutionary future, and second, in the process of learning how to direct evolution, we are bound to make mistakes. Our responsibility is to learn how to balance innovation with caution.-- Michael A. Goldman
The first part of the book introduces the essential underpinnings of molecular ecology and gives a review of genetics and discussion of the molecular markers that are most frequently used in ecological research, and a chapter devoted to the newly emerging field of ecological genomics. The second half of the book covers specific applications of molecular ecology, covering phylogeography, behavioural ecology and conservation genetics.
The new edition provides a thoroughly up-to-date introduction to the field, emphasising new types of analyses and including current examples and techniques whilst also retaining the information-rich, highly readable style which set the first edition apart.Incorporates both theoretical and applied perspectives Highly accessible, user-friendly approach and presentation Includes self-assessment activities with hypothetical cases based on actual species and realistic data sets Uses case studies to place the theory in context Provides coverage of population genetics, genomics, phylogeography, behavioural ecology and conservation genetics.
