What defines who we are? For decades, the answer has seemed obvious: our genes, the "blueprint of life." In The Master Builder, biologist Alfonso Martinez Arias argues we've been missing the bigger picture. It's not our genes that define who we are, but our cells.

The author of Seven Daughters of Eve returns with a lively account of how all dogs are descended from a mere handful of wolves.

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.

Blending history, science, and culture, a stunning and highly engaging evolutionary story exploring how walking on two legs allowed humans to become the planet’s dominant species.

Tucked away in Siberia, there are furry, four-legged creatures with wagging tails and floppy ears that are as docile and friendly as any lapdog. But, despite appearances, these are not dogs - they are foxes. They are the result of the most astonishing experiment in breeding ever undertaken - imagine speeding up thousands of years of evolution into a few decades. In 1959, biologists Dmitri Belyaev and Lyudmila Trut set out to do just that, by starting with a few dozen silver foxes from fox farms in the USSR and attempting to recreate the evolution of wolves into dogs in real time.

What is human consciousness, and how is it possible? This question fascinates thinking people from poets and painters to physicists, psychologists, and philosophers. From Bacteria to Bach and Back is Daniel C. Dennett's brilliant answer, extending perspectives from his earlier work in surprising directions, exploring the deep interactions of evolution, brains, and human culture.

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

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.

In this extraordinary follow-up to the critically acclaimed The Lucifer Principle, Howard Bloom - one of today's preeminent thinkers - offers us a bold rewrite of the evolutionary saga. Global Brain is more than just a brilliantly original contribution to the ongoing debate on the inner workings of evolution; it is a "grand vision," says the eminent evolutionary biologist David Sloan Wilson, a work that transforms our very view of who we are and why.

The entirety of the human brain’s 4-billion-year story can be summarised as the culmination of five evolutionary breakthroughs, starting from the very first brains, all the way to the modern human brains. Each breakthrough emerged from new sets of brain modifications, and equipped animals with a new suite of intellectual faculties. These five breakthroughs are the organising map to this book, and they make up our itinerary for our adventure back in time. Each breakthrough also has fascinating corollaries to breakthroughs in AI.

In A Story of Us, they present this rich narrative and explain how the evolution of our genes relates to the evolution of our cultures. Newson and Richerson take listeners through seven stages of human evolution, beginning seven million years ago with the apes that were the ancestors of humans and today's chimps and bonobos. The story ends in the present day and offers a glimpse into the future.

When we see a bird flying from branch to branch happily chirping, it is easy to imagine they lead a simple life of freedom, flight, and feathers. What we don't see is the arduous, life-threatening challenges they face at every moment. Beaks, Bones and Bird Songs guides the listener through the myriad, and often almost miraculous, things that birds do every day to merely stay alive. Like the goldfinch, which manages extreme weather changes by doubling the density of its plumage in winter.

Charles Darwin's foremost biographer, Janet Browne, delivers a vivid and accessible introduction to the book that permanently altered our understanding of what it is to be human. A sensation on its publication in 1859, The Origin of the Species profoundly shocked Victorian readers by calling into question the belief in a Creator with its description of evolution through natural selection. And Darwin's seminal work is nearly as controversial today.

With warmth and compassion, Denworth weaves together past and present, field biology and cutting-edge neuroscience, to show how our bodies and minds are designed to make friends, the process by which social bonds develop, and how a drive for friendship underpins human (and nonhuman) society. With its refreshingly optimistic vision of the evolution of human nature, this book puts friendship at the center of our lives.

Posiblemente uno de los ensayos científicos más conocidos y con más predicamento en todo el planeta, "El origen de las especies" es un texto capital a la hora de entender la teoría de la evolución y la selección natural tal y como las conocemos hoy en día. En él, Charles Darwin recogió sus conclusiones a través de pruebas fósiles encontradas a lo largo de un extenso viaje a bordo de la expedición del HMS Beagle. El resultado fue una de las teorías científicas más asentadas en el mundo hoy en día.

Mary Anning was only 12 years old when, in 1811, she discovered the first dinosaur skeleton - of an ichthyosaur - while fossil hunting on the cliffs of Lyme Regis, England. Until Mary's incredible discovery, it was widely believed that animals did not become extinct.

In Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.

In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies, as well as their feats of skill and endurance. The results have been momentous. Scientists have identified more than 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.

Some 73,000 years ago, the Mount Toba supervolcano in toda's Indonesia erupted, releasing the energy of a million tons of explosives. So much ash and debris was injected into the stratosphere that it partially blocked the sun's radiation and caused global temperatures to drop for a decade. In this book, Donald R. Prothero presents the controversial argument that the Toba catastrophe nearly wiped out the human race, leaving only about a thousand to ten thousand breeding pairs of humans worldwide.

Feathers are an evolutionary marvel: Aerodynamic, insulating, beguiling. They date back more than 100 million years. Yet their story has never been fully told. In Feathers, biologist Thor Hanson details a sweeping natural history, as feathers have been used to fly, protect, attract, and adorn through time and place. Applying the research of paleontologists, ornithologists, biologists, engineers, and even art historians, Hanson asks: What are feathers? How did they evolve? What do they mean to us?
