Showing titles in Evolution & Genetics

Looked at objectively, beneath the superficial appearance of design, the human body, with its inefficiencies, vulnerabilities, and vestigial features, is best explained through the lens of evolution. Far from reflecting intelligent design, our anatomy and physiology reveal a history of incremental changes shaped by natural selection and constrained by pre-existing structures. These imperfections underscore the reality of evolution as a tinkering process, producing functional but far-from-perfect outcomes. In this light, the human body stands as a powerful testament to our evolutionary ...

Vor 100.000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70.000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens.

Tim Flannery’s first major book since The Weather Makers charts the history of life on our planet. Here on Earth, which draws its points of departure from Darwin and Wallace, Lovelock and Dawkins, is an extraordinary exploration of evolution and sustainability. Our success as a species has had disastrous effects on many of the Earth’s ecosystems and could lead to our downfall. But equally, Flannery argues, we are now equipped as never before to explore our true relationship with the planet on which our biological, economic and cultural futures depend.

We humans have an extraordinary capacity for compassion—much of it in response to the atrocities we inflict on the planet, its animals, and each other. The popular explanation for this paradox is that we evolved as carnivorous “killer apes,” who gradually curbed our lust for violence (with frequent exceptions) by implementing humane social norms. This explanation is so well worn, especially in the American psyche, that it epitomizes cliché. So, we could be forgiven for believing it, when nearly every word is fiction.

Why are conditions like autism, asthma, obesity, and allergies exploding at unprecedented rates? Why are we living longer, getting smarter, having far fewer kids? If Darwin were alive today, how would he explain this new world?

Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built - and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.

Between what can be learned from evolutionary psychology and cognitive science a picture emerges. In Sex, Murder, and the Meaning of Life, social psychologist Douglas Kenrick fuses these two fields to create a coherent story of human nature. In his analysis, many ingrained, apparently irrational behaviors—one-night stands, prejudice, conspicuous consumption, even art and religious devotion—are quite explicable and (when desired) avoidable.

Most claims of Native American ancestry rest on the mother's ethnicity. This can be verified by a DNA test determining what type of mitochondrial DNA she passed to you. A hundred participants in DNA Consultants multi-phase Cherokee DNA Study did just that. What they had in common is they were previously rejected - by commercial firms, genealogy groups, government agencies and tribes. Their mitochondrial DNA was not classified as Native American. These are the "anomalous" Cherokee.

We evolved to eat berries rather than bagels, to live in mud huts rather than condos, to sprint barefoot rather than play football - or did we? Are our bodies and brains truly at odds with modern life? Although it may seem as though we have barely had time to shed our hunter-gatherer legacy, biologist Marlene Zuk reveals that the story is not so simple. Popular theories about how our ancestors lived - and why we should emulate them - are often based on speculation, not scientific evidence. Armed with a razor-sharp wit and brilliant, eye-opening research, Zuk takes us to the cutting edge of biology to show that evolution can work much faster than was previously realized.

Weaving together family history, genetic discovery, and scenes from her life, Ami McKay tells the compelling, true-science story of her own family's unsettling legacy of hereditary cancer while exploring the challenges that come from carrying the mutation that not only killed many people you loved, but might also kill you.

Growing up in California, J. Craig Venter didn't appear to have much of a future. An unremarkable student, he nearly flunked out of high school. After being drafted into the army, he enlisted in the Navy and went to Vietnam, where the life-and-death struggles he encountered as a medic piqued his interest in science and medicine. After pursuing his advanced degrees, Venter quickly established himself as a brilliant and outspoken scientist.

What is animal welfare? This concise and accessible guide is for anyone who is interested in animals and who has wondered how we can assess their welfare scientifically. It defines animal welfare as "health and animals having what they want", a definition that can be easily understood by scientists and non-scientists alike, expresses in simple words what underlies many existing definitions, and shows what evidence we need to collect to improve animal welfare in practice. Above all, it puts the animal's own point of view at the heart of an assessment of its welfare.

The DNA Restart, by world-renowned neurogeneticist and New York Times best-selling author Dr. Sharon Moalem, walks you through revolutionary steps to a diet and lifestyle perfect for your individual genetic makeup. The DNA Restart plan utilizes decades of in-depth scientific research into genetics, epigenetics, nutrition, and longevity to explain the pivotal role genes play in the journey to ideal weight and health status.

Most people know that Gregor Mendel, the Moravian monk who patiently grew his peas in a monastery garden, shaped our understanding of inheritance. But people might not know that Mendel's work was ignored in his own lifetime, even though it contained answers to the most pressing questions raised by Charles Darwin's revolutionary book, On Origrin of the Species, published only a few years earlier. Mendel's single chance of recognition failed utterly, and he died a lonely and disappointed man.

A fascinating survey of the forces that shape who we are and how we act - from the author of The Calculus Diaries. Following her previous tours through the worlds of physics ( Black Bodies and Quantum Cats) and calculus ( The Calculus Diaries), acclaimed science writer Jennifer Ouellette now turns her attention to the mysteries of human identity and behavior with Me, Myself, and Why.

Few people know much about stem cell research beyond the ethical questions raised by using embryos. But in the last decade, stem cell research has made huge advances toward eliminating some of our most intractable diseases. Now this sweeping and accessible book introduces us to this cutting-edge science, which will revolutionize medicine and change the way we think about and treat disease.

Are the ways we look at menopause all wrong? Historian Susan Mattern says yes, and The Slow Moon Climbs reveals just how wrong we have been. Taking listeners from the rainforests of Paraguay to the streets of Tokyo, Mattern draws on historical, scientific, and cultural research to reveal how our perceptions of menopause developed from prehistory to today. For most of human history, people had no word for menopause and did not view it as a medical condition. Rather, in traditional foraging and agrarian societies, it was a transition to another important life stage.

In How We Do It, primatologist Robert Martin draws on 40 years of research to locate the roots of everything from our sex cells to the way we care for newborns. He examines the procreative history of humans as well as that of our primate kin to reveal what's really natural when it comes to making and raising babies, and distinguish which behaviors we ought to continue - and which we should not. Although it's not realistic to raise our children like our ancestors did, Martin’s investigation reveals surprising consequences of - and suggests ways to improve upon - the way we do things now.

For an era in which Darwin is more talked about than read, Daniel Duzdevich offers a clear, modern English rendering of Darwin's first edition. Neither an abridgement nor a summary, this version might best be described as a "translation" for contemporary English listeners. A monument to reasoned insight, the Origin illustrates the value of extensive reflection, carefully gathered evidence, and sound scientific reasoning.

Leading archaeogeneticist Johannes Krause and journalist Thomas Trappe investigate what DNA can tell us about how we got where we are and what our future might be. They show how the first humans were defeated again and again and suffered fatal setbacks, and how Homo sapiens succeeded in conquering continents, overcoming natural borders, and bringing other species under its control. But the genetic blueprint that enabled us to get to the place where we are today had one flaw: it didn't factor in planetary boundaries.
