Her name was Henrietta Lacks, but scientists know her as HeLa. She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells - taken without her knowledge - became one of the most important tools in medicine: The first “immortal” human cells grown in culture, which are still alive today, though she has been dead for more than 60 years. HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects.

We humans like to think of ourselves as highly evolved creatures. But if we are supposedly evolution's greatest creation, why do we have such bad knees? Why do we catch head colds so often - 200 times more often than a dog does? How come our wrists have so many useless bones? And are we really supposed to swallow and breathe through the same narrow tube? Surely there's been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last.

Charles Darwin’s theory of evolution now forms the basis for all the life sciences, but it ignited widespread controversy upon its 1859 publication. The idea that humans and animals might have evolved from a common source came as a shock to readers at the time, and people struggle with the implications of Darwin’s theory to this day. But Darwin foresaw this resistance and argued his case with extensive examples and rigorous logic - and his theory continues to push us toward a deeper understanding of life on Earth.

Survival of the Beautiful is a revolutionary new examination of the interplay of beauty, art, and culture in evolution. Taking inspiration from Darwin's observation that animals have a natural aesthetic sense, philosopher and musician David Rothenberg probes why animals, humans included, have innate appreciation for beauty - and why nature is, indeed, beautiful.

Susan Casey is our premiere chronicler of the aquatic world. For The Underworld she traversed the globe, joining scientists and explorers on dives to the deepest places on the planet, interviewing the marine geologists, marine biologists, and oceanographers who are searching for knowledge in this vast unseen realm. She takes us on a fascinating journey through the history of deep-sea exploration, from the myths and legends of the ancient world to storied shipwrecks we can now reach on the bottom.

Symbiosis, the sustained and intimate associations between unrelated life forms, is now recognized as a ubiquitous phenomenon, one that has shaped evolution since the origin of life and that continues to affect all species. This overview of symbiosis starts with a quick history of relevant early discoveries and researchers, and considers why symbiosis was so long neglected as a respectable topic of biological research and why it was a controversial topic. Today, symbiosis is widely appreciated as being everywhere in nature and as a pervasive influence on ecological communities.

Perfect for fans of horror and science alike, Rise of the Zombie Bugs offers a chilling yet enlightening look at the hidden world of parasites. It's a must-listen for anyone curious about the true terrors lurking in nature's undergrowth and the unnerving beauty of evolution's darker side.

Synthetic Biology: Life’s Extraordinary New Worlds is an introduction to synthetic biology for non-scientists, covering the exciting field that is transforming health care, agriculture, environmental science, and many other areas. Using the molecules of life to answer scientific questions and manipulate life for human benefit, synthetic biology encompasses a wide range of applications—from gene editing and metabolic engineering to food synthesis and green technologies.

Ants number in the ten quadrillions, and they have been here since the Jurassic era. Inside an anthill, you'll find high drama worthy of a royal court; and between colonies, high-stakes geopolitical intrigue is afoot. Just like us, ants grow crops, raise livestock, tend their young and infirm, and make vaccines. And, just like us, ants have a dark side: They wage war, despoil environments, and enslave rivals - but also rebel against their oppressors.

Morange covers everything from the first cell theory to the origins of the concept of ecosystems, and offers perspectives on areas that are often neglected by historians of biology, such as ecology, ethology, and plant biology. He highlights the contributions of technology, the important role of hypothesis and experimentation, and the cultural contexts in which some of the most breathtaking discoveries in biology were made. Unrivaled in scope and written by a world-renowned historian of science, A History of Biology is an ideal introduction for students and experts alike.

At once elegant and riveting, Sync tells the story of the dawn of a new science. Steven Strogatz, a leading mathematician in the fields of chaos and complexity theory, explains how enormous systems can synchronize themselves, from the electrons in a superconductor to the pacemaker cells in our hearts. He shows that although these phenomena might seem unrelated on the surface, at a deeper level there is a connection, forged by the unifying power of mathematics.

We human beings share 98 percent of our genes with chimpanzees. Yet humans are the dominant species on the planet - having founded civilizations and religions, developed intricate and diverse forms of communication, learned science, built cities, and created breathtaking works of art - while chimps remain animals concerned primarily with the basic necessities of survival. What is it about that two percent difference in DNA that has created such a divergence between evolutionary cousins?

By identifying the structure of DNA, the molecule of life, Francis Crick and James Watson revolutionized biochemistry and won themselves a Nobel Prize. At the time, Watson was only 24, a young scientist hungry to make his mark. His uncompromisingly honest account of the heady days of their thrilling sprint against other world-class researchers to solve one of science's greatest mysteries gives a dazzlingly clear picture of a world of brilliant scientists with great gifts, very human ambitions, and bitter rivalries.

Before there were mammals on land, there were dinosaurs. And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth's first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean's former top predator became its most delicious snack. Cephalopods had to step up their game.

In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field is horizontal gene transfer (HGT), or the movement of genes across species lines. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection - a type of HGT. In The Tangled Tree David Quammen chronicles these discoveries through the lives of the researchers who made them.

"Ants are the most warlike of all animals, with colony pitted against colony.... Their clashes dwarf Waterloo and Gettysburg", writes Edward O. Wilson in his most finely observed work in decades. In a myrmecological tour to such far-flung destinations as Mozambique and New Guinea, the Gulf of Mexico's Dauphin Island and even his parents' overgrown yard back in Alabama, Wilson thrillingly evokes his nine-decade-long scientific obsession with more than 15,000 ant species.

In Survival of the Prettiest, Nancy Etcoff, a faculty member at Harvard Medical School and a practicing psychologist at Massachusetts General Hospital, argues that beauty is neither a cultural construction, an invention of the fashion industry, nor a backlash against feminism - it's in our biology.

First coined by Richard Dawkins in The Selfish Gene, a meme is any idea, behavior, or skill that can be transferred from one person to another by imitation. Susan Blackmore shows that once our distant ancestors acquired the crucial ability to imitate, a second kind of natural selection began, a survival of the fittest amongst competing ideas and behaviors. Ideas and behaviors that proved most adaptive-making tools, for example, or using language - survived and flourished, replicating themselves in as many minds as possible.

Growth has been both an unspoken and an explicit aim of our individual and collective striving. It governs the lives of microorganisms and galaxies; it shapes the capabilities of our extraordinarily large brains and the fortunes of our economies. Growth is manifested in annual increments of continental crust, a rising gross domestic product, a child's growth chart, the spread of cancerous cells. In this magisterial book, Vaclav Smil offers systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations.

Cuando se encierra a un lobo, comienza a dar vueltas en su jaula, se activan sus mecanismos de defensa, su astucia natural se agudiza con el objetivo de escapar y, finalmente, aúlla. Si confinan a un zoólogo documentalista, se pondrá, de inmediato, a investigar acerca del motivo de su aislamiento; pero, cuando le digan que un pangolín y un murciélago son la causa de todo, se dará cuenta de que algo no encaja.
