In From Darwin to Derrida, evolutionary biologist David Haig explains how a physical world of matter in motion gave rise to a living world of purpose and meaning. Natural selection, a process without purpose, gives rise to purposeful beings who find meaning in the world. The key to this, Haig proposes, is the origin of mutable “texts”―genes―that preserve a record of what has worked in the world. These texts become the specifications for the intricate mechanisms of living beings.

More than half a billion years ago, our world was completely covered by glaciers, a "Snowball Earth" that persisted for millions of years. Incredibly, this unimaginable cold led to the remarkable diversification of life on earth known as the Cambrian explosion. With a geologist's eye and a knack for storytelling, Graham Shields explores when and how such inhospitable conditions enabled animals to evolve, radiate, and diversify into our earliest ancestors.

Among scientists who write, no one illuminates as well as Stephen Jay Gould does the wonderful workings of the natural world. Now in a new volume of collected essays—his sixth since Ever Since Darwin—Gould speaks of the importance of unbroken connections within our own lives and to our ancestral generations. Along with way, he opens to us the mysteries of fish tails, frog calls, and other matters, and shows once and for all why we must take notice when a seemingly insignificant creature is threatened, like the land snail Partula from Moorea, whose extinction he movingly relates.

Homo sapiens emerged as a species about 200,000 years ago and soon—with fire, simple tools, and an egalitarian social system—we inhabited every continent. But now our infinitely elaborated tools and our highly non-egalitarian social system threaten sustainability. Many at the bottom lose the desire to live, committing suicide or succumbing to drugs, alcohol, and obesity. What is Health? explains from the bottom up—molecules to society—how we reached this point.

The language of genes has become common parlance. We know they make your eyes blue, your hair curly or your nose straight. The media tells us that our genes control the risk of cancer, heart disease, alcoholism or Alzheimer's. The cost of DNA sequencing has plummeted from billions of pounds to a few hundred, and gene-based advances in medicine hold huge promise. So we've all heard of genes, but how do they actually work?

In 2010, scientists led by J. Craig Venter became the first to successfully create "synthetic life" - putting humankind at the threshold of the most important and exciting phase of biological research, one that will enable us to actually write the genetic code for designing new species to help us adapt and evolve for long-term survival. The science of synthetic genomics will have a profound impact on human existence, including chemical and energy generation, health, clean water and food production, environmental control, and possibly even our evolution.

We've all asked ourselves the question. It's impossible to look up at the stars and NOT think about it: Are we alone in the universe? Books, movies, and television shows proliferate that attempt to answer this question and explore it. In Out There, Space.com senior writer Dr. Michael Wall treats that question as merely the beginning, touching off a wild ride of exploration into the final frontier. He considers, for instance, the myriad of questions that would arise once we do discover life beyond Earth (an eventuality which, top NASA officials told Wall, is only drawing closer).

Unravelling the Double Helix covers the most colourful period in the history of DNA, from the discovery of 'nuclein' in the late 1860s to the publication of Watson's The Double Helix in 1968. This is a saga packed with awful mistakes as well as brilliant science, with a wonderful cast of heroes and villains. Surprisingly, much of it is unfamiliar because the early history is largely neglected by books which focus on the episode of the double helix.

How is it that Homo sapiens formed such a special relationship with what, on the face of it, is a most unlikely ally? It is more than just a story of domestication but an astonishing example of the co-evolution of two species, man and wolf, to each other's mutual benefit. This co-evolution was a vital step in helping Homo sapiens overcome competition from other human species and to expand in numbers from relative obscurity on the margins towards the overwhelming numerical superiority and influence that we enjoy today.

Orphan is about the struggle to save the lives of children who, because of an unlucky roll of the genetic dice, are born with any one of several thousand rare genetic disorders. Many are burdened with diseases that carry mysterious names, some of which you will hear about for the first time in this audiobook, along with compelling stories about the physicians, scientists, and parents who have taken them on.

In Unfit for Purpose, biologist and broadcaster Adam Hart explores the mismatch between our fundamental biology and the modern world we have created. In each chapter Adam reveals the many ways in which biological adaptations that evolved to help us survive and thrive now work against us. For example, in the modern world stress is a killer, but how did 'fight or flight' instincts turn from life-savers to life-takers? Obesity might be a disease now, but is it really just a troublesome side-effect of our complex evolutionary past?

This lively history traces the evolution of the idea of evolution, showing how it has changed and been changed by different societies over time. It will put 'Darwin’s Dangerous Idea' into its proper context, showing how it built on what went before and how it was developed in the 20th century, through an understanding of genetics and the biochemical basis evolution. None of this diminishes the achievement of Darwin himself, but his contribution was one link in a chain that extends back into antiquity and is still being forged today.

50 Great Myths of Human Evolution uses common misconceptions to explore basic theory and research in human evolution and strengthen critical thinking skills for lay audiences, listeners, and students. Includes myths such as: "Humans lived at the same time as dinosaurs"; "Lucy was so small because she was a child"; "Our ancestors have always made fire"; and "There is a strong relationship between brain size and intelligence."

Binary is the ultimate guide for understanding and dismantling the sex spectrum, the new cultural belief that sex exists on a continuum and that male and female are social constructs. By analyzing its 10 most popular arguments, Zachary A. Elliott reveals how the tenets of the sex spectrum deny evolution, development, and genetics. Using the primary biology literature, the book provides the listener with a comprehensive scientific understanding of how the two sexes are universal phenomena and how complex genetic networks consistently result in a simple yet profound outcome: male or female.

Dépression, syndrome d'anniversaire, empêchement, angoisse... Et si ces difficultés faisaient partie d'un héritage familial inconscient ? Sans le savoir, sans le vouloir, nous recevons de nos ancêtres la mémoire d'événements cachés survenus avant notre naissance. Ces traumatismes invisibles, non-dits, secrets de famille, peuvent produire leurs effets néfastes sur plusieurs générations. Ce livre vous aidera à les identifier, pour rompre avec le destin répétitif de votre histoire familiale, vous apaiser et reconquérir votre liberté. Un des grands classiques de la transgénéalogie.

Before Charles Darwin, other luminaries planted the seeds that would one day evolve into the theory that would make him famous. Author Rick Coste begins by shining a spotlight on the writers, philosophers, and scientists who planted the seeds that would blossom into the theory of evolution by natural selection, from Aristotle’s big ideas to young Mary Anning’s discovery of the first ichthyosaur skeleton. After exploring the contributions of Charles Darwin and Alfred Russel Wallace, Evolution Talk investigates the very beginnings of life itself.

Today, with relatively easy access to our DNA ancestry, we have more data about ourselves and family history than previous generations could have imagined. In the 12 fascinating lessons of Identity in the Age of Ancestral DNA, Anita Foeman, PhD, professor of communication and media, and founder and primary investigator of the DNA Discussion Project at West Chester University, takes us behind the scenes to examine what really happens when individuals receive their personal DNA ancestry results.

Vital research is starting to challenge long-standing assumptions about gender identity and biological sex, such as work that indicates the brain is a “mosaic” of traits rather than a “male” and “female” brain. Growing knowledge of the genetic complexities of sexual determination is changing the way the medical community treats intersex individuals, and in this audiobook, The New Science of Sex and Gender, we not only examine the latest studies in biology, medicine, and psychology but also, more importantly, their bearing on healthcare, identity, and access.

Around 250,000 people have had their genomes sequenced, and scientists expect that number to rise to one billion by 2025. Professor Steven J. Heine argues that the first thing we will do on receiving our DNA test results is to misinterpret them completely. Despite breathless (often lightly researched) media coverage about newly discovered "cancer" or "divorce" or "IQ" genes, the prospect of a DNA test forecasting how your life is going to turn out is vanishingly small.

There is a human genetic fluke that is surprisingly common, due to a change in a key pair of chromosomes. In the normal condition the two look the same, but in this disorder one is malformed and shrunken beyond recognition. The result is a shortened life span, higher mortality at all ages, an inability to reproduce, premature hair loss, and brain defects variously resulting in attention deficit, hyperactivity, conduct disorder, hypersexuality, and an enormous excess of both outward and self-directed aggression. It is called maleness.
