Hvem er jeg? En dna-kode oversat til kød og blod er det hurtige svar, men hvad betyder det? Bestemmer den nedarvede kode alt fra min hårfarve over partnervalg til jobsituation eller har "jeg" noget at skulle have sagt her? Er der i det hele taget et frit og ubundet "jeg", eller gennemspiller "jeg" bare et computerprogram i dna-kode, der dikterer mit liv og min død? Lone Frank har i "Mit smukke genom" sat sig for at finde ud af så meget om sine egne gener som muligt.

The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures—including our own ancestors.

Parents and parents-to-be are bombarded with information, from what to expect to what to do (and not to do) when it happens. But what they may not realize is that from the chemistry of pregnancy tests to the vacuum physics of breastfeeding, there is fascinating science at the heart of every aspect of creating and raising a new human.

Presenting scientific evidence from diverse fields, including anthropology, biology, and psychology, Fuentes devises a myth-busting toolkit to dismantle persistent fallacies about the validity of biological races, the innateness of aggression and violence, and the nature of monogamy, sex, and gender. This revised and expanded edition provides up-to-date references, data, and analyses, and addresses new topics, including the popularity of home DNA testing kits and the lies behind ‘"incel" culture.

Hace unos 4.000 millones de años apareció la vida en la Tierra. ¿Cuál es la historia de su evolución? ¿Era inevitable la vida? ¿Y la raza humana? ¿La habría habitado algún otro ser inteligente, si no hubiera habido humanos? ¿Qué patrones usa el mecanismo evolutivo? ¿La evolución avanza hacia adelante como una flecha?

En este nuevo libro, Jorge Dotto, médico patólogo y genetista, autor también de Genética. Cómo puede cambiar nuestras vidas, nos explica de modo ameno y entretenido, de qué manera los genes participan en nuestras situaciones de placer, al tiempo que subraya la importancia de los factores ambientales y la propia voluntad de las personas para lograr un mejor vínculo con las distintas formas de recompensarse.

Everywhere there are characteristics of animals that do not want to fit into the theory of evolution anywhere. And man? Are we really the most adapted life-form on this planet? Today, more and more scientists who contradict the previous theory of evolution speak out. The theory fits the changes within the species, but it can no longer be reconciled with the inner workings of the cell. Some other influence that has so far escaped us is affecting evolution. It is called "Intelligent Design." Intelligent planning is suspected behind this.

The world is in crisis! What is the solution? Ultimately, we have to find the redeeming, and thus transforming, understanding of our psychologically troubled human condition. And it is precisely that dreamed-of insight, and its now desperately needed transformation of our lives, that Australian biologist Jeremy Griffith presents in this book.

Minding the Climate investigates this problem in the neuroscience of decision-making. Ann-Christine Duhaime, MD, points to the evolution of the human brain during eons of resource scarcity. The brain adapted to prioritize short-term survival over more uncertain long-term outcomes. But the resulting behavioral architecture is poorly suited to the present, when scarcity is a lesser concern and slow-moving challenges like environmental issues present the greatest danger.

In this book, two distinguished scientists tackle common misconceptions about race, human biology, and racism. Using an accessible question-and-answer format, Joseph L. Graves Jr. and Alan H. Goodman explain the differences between social and biological notions of race. Although there are many meaningful human genetic variations, they do not map onto socially constructed racial categories. Drawing on evidence from both natural and social science, Graves and Goodman dismantle the malignant myth of gene-based racial difference.

Our senses are at the heart of how we navigate the world. Whittling this high-powered and deliciously varied palette down to just five does a great disservice to the sensory experience, Sensational argues. In fact, we could have as many as fifty-three—and they could explain such mysteries as why we kiss, in what way music is a form of emotional currency, and how a dairy-rich diet strained initial Euro-Japanese relations. Ashley Ward embarks on a sensory expedition to answer all these questions and more.

Our ability to think about the future is one of the most powerful tools at our disposal. In The Invention of Tomorrow, cognitive scientists Thomas Suddendorf, Jonathan Redshaw, and Adam Bulley argue that its emergence transformed humans from unremarkable primates to creatures that hold the destiny of the planet in their hands. Drawing on their own cutting-edge research, the authors break down the science of foresight, showing us where it comes from, how it works, and how it made our world.

Immer mehr Einzelheiten werden darüber bekannt, wie epigenetische Prozesse die Aktivität von Genen steuern. Bisher wurde vor allem diskutiert, welchen Einfluss die Umwelt so auf unser Erbgut nehmen kann - mit Langzeitfolgen über Generationen hinweg. Doch inzwischen diskutieren Forschende, inwieweit sich diese Erkenntnisse auch gezielt medizinisch nutzen lassen.

You're invited to discover the wonder and drama of the history of the cosmos. Follow the journey of one proton who comes into existence at the beginning of creation and makes it all the way through history to today. By becoming a part of atoms and molecules that turn up at some of the universe's most important moments, our friend Proton witnesses emerging galaxies, the origin of life, evolution, the first human beings, the birth and life of Jesus, the beginnings of the Christian church, all the way up to the present day. Through it all, the plans of the Creator continue to unfold.

From a renowned historian comes a ground-breaking narrative of humanity’s creation and evolution, a number one international best seller that explores the ways in which biology and history have defined us and enhanced our understanding of what it means to be “human”.

The historical Jesus of Nazareth is arguably the most influential person ever to walk on the face of the planet Earth. For the past 2,000 years, thousands of books have been written about him, and yet no book has been written about the mechanism by which the eternally existing God—the Christ—became Jesus, the man in the flesh. This book precisely explains this mystery by looking through the prism of the scientific discipline of genetics.

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.

Es ist eine Frage, die sich Menschen seit Tausenden von Jahren stellen: Woher kommen wir? Nach Antworten suchen Fachleute auch in unserer DNA – und hier decken sie einige Sensationen auf. Im Erbgut von Homo sapiens befinden sich nämlich Abschnitte, die gar nicht von den Ahnen unserer Spezies stammen. Neandertaler, Denisovianer und weitere, noch unbekannte Vettern der Gattung Homo haben sich offenbar mit unseren Vorfahren gepaart und so zu unserem Genom beigetragen. Und auch unsere jüngere evolutionäre Vergangenheit hat markante Spuren in unseren Genen hinterlassen.

Just over 125,000 years ago, humanity was going extinct until a dramatic shift occurred—Homo sapiens started tracking the tides in order to eat the nearby oysters. Before long, they’d pulled themselves back from the brink of extinction. The human brain, and its evolutionary journey, is unlike anything else in history. In A History of the Human Brain, Bret Stetka takes listeners through that far-reaching journey. He also tackles the question of where the brain will take us next, exploring the burgeoning con­cepts of epigenetics and new technologies like CRISPR.

When attorney Chris Hansen learned that the U.S. government was issuing patents for human genes to biotech companies, his first thought was, How can a corporation own what makes us who we are? Then he discovered that women were being charged exorbitant fees to test for hereditary breast and ovarian cancers, tests they desperately needed—all because Myriad Genetics had patented the famous BRCA genes. So he sued them.

A new gene editing technology, invented just seven years ago, has turned humanity into gods. Enabling us to manipulate the genes in virtually any organism with exquisite precision, CRISPR has given scientists a degree of control that was undreamt of even in science fiction. But CRISPR is just the latest, giant leap in a long journey to master genetics. The Genetic Age shows the astonishing, world-changing potential of the new genetics and the possible threats it poses, sifting between fantasy and the reality when it comes to both benefits and dangers.

In his acclaimed Cosmosapiens, renowned scientist John Hands looked back on how we humans evolved from the origin of the universe to the present day. Building on that work, The Future of Humankind: Why We Should Be Optimistic looks ahead to our ultimate destiny. Listeners embark on a fascinating journey in which Hands evaluates current major predictions for our future in three categories—extinction, survival, and transformation—before making his own unique and astonishing forecast.

The puzzling lack of evidence for the peculiar but widespread belief that birds have no sense of smell irked evolutionary biologist Danielle Whittaker. Exploring the science behind the myth led her on an unexpected quest investigating mysteries from how juncos win a fight to why cowbirds smell like cookies. In The Secret Perfume of Birds―part science, part intellectual history, and part memoir―Whittaker blends humor, clear writing, and a compelling narrative to describe how scent is important not just for birds but for all animals, including humans.

In 2018, scientists manipulated the DNA of human babies for the first time. As biologist and historian Matthew Cobb shows in As Gods, this achievement was one many scientists have feared from the start of the genetic age. Four times in the last fifty years, geneticists, frightened by their own technology, have called a temporary halt to their experiments. They ought to be frightened.

Evolutionary science has long been regarded as conservative, a tool for enforcing regressive ideas, particularly about race and gender. But in A Voice in the Wilderness, evolutionary biologist Joseph L. Graves Jr.—once styled as the “Black Darwin”—argues that his field is essential to social justice. He shows, for example, why biological races do not exist. He dismantles recent work in “human biodiversity” seeking genes to explain the achievements of different ethnic groups. He decimates homophobia, sexism, and classism as well.

Among all life on Earth, we alone experience rich moral emotions, follow complex rules governing how we treat one another, and engage in moral dialogue. But how did human morality evolve? And can humans become morally evolved? In A Better Ape, Victor Kumar and Richmond Campbell draw on the latest research in the biological and social sciences to explain the key role that morality has played in human evolution.

No hay ningún plan de alimentación funcional para todo el mundo: lo que a unos les sienta bien, a otros puede hacerles daño. ¿Cómo se explica? Por el código genético, que es absolutamente único en cada persona.

A tiny mutation on the X chromosome can shape a family’s history. Passed down from a “carrier” parent to a child, fragile X syndrome is the most common inherited cause of intellectual disability and autism. Beyond that—and a rarity among genetic disorders—some fragile X carriers not only transmit the mutation, but also experience related conditions themselves.

For centuries, people have been returning to the same tired nature-versus-nurture debate, trying to determine what we learn and what we inherit. In Dancing Cockatoos and the Dead Man Test, biologist Marlene Zuk goes beyond the binary and instead focuses on interaction, or the way that genes and environment work together. Driving her investigation is a simple but essential question: How does behavior evolve?

In 10 riveting episodes, paleoanthropologist Elen Feuerriegel takes you on an unrivaled tour of the human fossil record in search of the biological and behavioral underpinnings of our very “humanness”.
