Evolving Ourselves: How Unnatural Selection and Nonrandom Mutation are Changing Life on Earth


Juan Enriquez - 2015
    We will directly and indirectly determine what lives, what dies, where, and when. We are in a different phase of evolution; the future of life is now in our hands.”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.

Dr. Hardy continues with insights into diet, nutrition myths, biochemistry demystified, intestinal fine-tuning, the chronic stress connection with disease, and then passes the baton to Marty Gallagher, who unleashes a plethora of exercise and training tips that are centered around five basic exercise categorie

The Developing Genome: An Introduction to Behavioral Epigenetics


David S. Moore - 2015
    But recent discoveries about how genes work have revealed a new way to understand the developmental origins of our characteristics. These discoveries have emerged from the new science of behavioral epigenetics--and just as the whole world has now heard of DNA, "epigenetics" will be a household word in the near future.Behavioral epigenetics is important because it explains how our experiences get under our skin and influence the activity of our genes. Because of breakthroughs in this field, we now know that the genes we're born with don't determine if we'll end up easily stressed, likely to fall ill with cancer, or possessed of a powerful intellect. Instead, what matters is what our genes do. And because research in behavioral epigenetics has shown that our experiences influence how our genes function, this work has changed how scientists think about nature, nurture, and human development. Diets, environmental toxins, parenting styles, and other environmental factors all influence genetic activity through epigenetic mechanisms; this discovery has the potential to alter how doctors treat diseases, and to change how mental health professionals treat conditions from schizophrenia to post-traumatic stress disorder. These advances could also force a reworking of the theory of evolution that dominated twentieth-century biology, and even change how we think about human nature itself.In spite of the importance of this research, behavioral epigenetics is still relatively unknown to non-biologists. The Developing Genome is an introduction to this exciting new discipline; it will allow readers without a background in biology to learn about this work and its revolutionary implications.

Inside the Cell: The Dark Side of Forensic DNA


Erin E. Murphy - 2015
    He was five inches shorter and 65 pounds lighter than the suspect described by the victim, but at trial a lab analyst testified that his DNA was found at the crime scene. His case looked like many others -- arrest, swab, match, conviction. But there was just one problem -- Sutton was innocent. We think of DNA forensics as an infallible science that catches the bad guys and exonerates the innocent. But when the science goes rogue, it can lead to a gross miscarriage of justice. Erin Murphy exposes the dark side of forensic DNA testing: crime labs that receive little oversight and produce inconsistent results; prosecutors who push to test smaller and poorer-quality samples, inviting error and bias; law-enforcement officers who compile massive, unregulated, and racially skewed DNA databases; and industry lobbyists who push policies of "stop and spit." DNA testing is rightly seen as a transformative technological breakthrough, but we should be wary of placing such a powerful weapon in the hands of the same broken criminal justice system that has produced mass incarceration, privileged government interests over personal privacy, and all too often enforced the law in a biased or unjust manner. Inside the Cell exposes the truth about forensic DNA, and shows us what it will take to harness the power of genetic identification in service of accuracy and fairness.

Everyone Is African: How Science Explodes the Myth of Race


Daniel J. Fairbanks - 2015
    Both geneticists and anthropologists now generally agree that the human species originated in sub-Saharan Africa and darkly pigmented skin was the ancestral state of humanity. Moreover, worldwide human diversity is so complex that discrete races cannot be genetically defined. And for individuals, ancestry is more scientifically meaningful than race.Separate chapters are devoted to controversial topics: skin color and the scientific reasons for the differences; why ancestry is more important to individual health than race; intelligence and human diversity; and evolutionary perspectives on the persistence of racism.This is an enlightening book that goes a long way toward dispelling the irrational notions at the heart of racism.

Measuring Manhood: Race and the Science of Masculinity, 1830–1934


Melissa N. Stein - 2015
    Measuring Manhood shows where they got their start.Melissa N. Stein analyzes how race became the purview of science in nineteenth- and early twentieth-century America and how it was constructed as a biological phenomenon with far-reaching social, cultural, and political resonances. She tells of scientific “experts” who advised the nation on its most pressing issues and exposes their use of gender and sex differences to conceptualize or buttress their claims about racial difference. Stein examines the works of scientists and scholars from medicine, biology, ethnology, and other fields to trace how their conclusions about human difference did no less than to legitimize sociopolitical hierarchy in the United States.Covering a wide range of historical actors from Samuel Morton, the infamous collector and measurer of skulls in the 1830s, to NAACP leader and antilynching activist Walter White in the 1930s, this book reveals the role of gender, sex, and sexuality in the scientific making?and unmaking?of race.

Orphan: The Quest to Save Children with Rare Genetic Disorders


Philip R. Reilly - 2015
    Many are burdened with diseases that carry mysterious names, some of which you can read about for the first time in this book, along with compelling stories about the physicians, scientists, and parents who have taken them on. The diseases include phenylketonuria, sickle cell anemia, dystrophic epidermolysis bullosa, X-linked hypohidrotic ectodermal dysplasia, and Friedreich's ataxia-just a few of the more than 1000 genetic disorders that are well-described and many more that are not. Many manifest in infancy. Some show up in mid-childhood, others later in childhood, and still others among adults. They touch almost every extended family. Orphan is more than a book about disease and research--it gives voice to thousands of people who, all too often, have endured terrible illnesses, bravely faced arduous clinical trials, and, sometimes, have gained victories, almost always in silence. This book recounts extraordinary breakthroughs and hopes for the future. Many of the disorders that will end our lives are in some part genetically influenced. We really are all orphans, and this book is for all of us.
