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.

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”.

Die CRISPR-Methode und die Zukunft der Medizin. Was macht die Natur, wenn ein neuer Feind auftaucht? Sie findet eine neue Strategie. Wenn eine Bakterie von einem Virus attackiert wird, verteidigt sie sich beispielsweise, indem sie ihre genetische Struktur ändert. Doch wie können diese Mechanismen nachgewiesen werden? Und welchen Nutzen hat dieses Wissen für die Medizin? Der Amerikanerin Jennifer Doudna und der Französin Emmanuelle Charpentier sind bahnbrechende Erkenntnisse im Bereich der Biochemie gelungen.

«Nos encantaría descubrir que cada especie tiene un reloj biológico en sus células, porque, de existir ese reloj y si fuéramos capaces de dar con él, quizá pudiéramos pararlo y de ese modo volvernos eternos», le plantea Arsuaga a Millás en este libro en el que la ciencia se entrelaza con la literatura. El paleontólogo desvela aspectos esenciales de nuestra existencia al escritor, y se debate sobre la conveniencia de transmitir su visión azarosa de la vida a un Millás a dieta que descubre que la vejez es un país en el que todavía se siente extranjero.

The possibility of life elsewhere in the cosmos is one of the most profound subjects that human beings can ponder. Astrophysicist Andrew May gives an expert overview of our current state of knowledge, looking at how life started on Earth, the tell-tale ‘signatures’ it produces and how such signatures might be detected elsewhere in the solar system or on the many ‘exoplanets’ now being discovered by the Kepler and TESS missions.

In November 1987, a young couple on an overnight trip to Seattle vanished without a trace. A week later, the bodies of Tanya Van Cuylenborg and her boyfriend Jay Cook were found in rural Washington. It was a brutal crime, and it was the perfect crime: With few clues and no witnesses, an international manhunt turned up empty, and the sensational case that shocked the Pacific Northwest gradually slipped from the headlines.

An almost limitless archive of our history lies hidden inside our bodies, and this book traces the ancient story of Scotland from that scientific viewpoint. The mushrooming of genetic studies, of DNA analysis, is rewriting history in spectacular fashion. In Scotland: A Genetic Journey, Alistair Moffat explores the history that is printed on our genes, and in a remarkable new approach, uncovers the detail of where Scots are from, where they have journeyed, and who they are - and in so doing, vividly colors in a DNA map of Scotland.

The field of biotechnology has evolved over the past four decades, developing medicines which are curing diseases. But this journey of success has been tough and arduous, built upon the shoulders of major failures.

We’ve come a long way. The earliest human had a brain as small as a child’s fist; ours are four times bigger, with spectacular abilities and potential we are only just beginning to understand. This is How the Mind Changed, a seven-million-year journey through our own heads, packed with vivid stories, groundbreaking science, and thrilling surprises. Discover how memory has almost nothing to do with the past.

Viruses are the world's most abundant life form, and now, when humanity is in the midst of a close encounter with their immense power, perhaps the most feared. But do we understand viruses? Possibly the most enigmatic of living things, they are sometimes not considered a life form at all. Everything about them is extreme, including the reactions they evoke. However, for every truism about viruses, the opposite is also often true.
