Where did I come from? Why do I have two arms but just one head? How is my left leg the same size as my right one? Why are the fingerprints of identical twins not identical? How did my brain learn to learn? Why must I die? Questions like these remain biology's deepest and most ancient challenges. They force us to confront a fundamental biological problem: How can something as large and complex as a human body organize itself from the simplicity of a fertilized egg?

The Log from the Sea of Cortez is the exciting day-by-day account of Steinbeck's trip to the Gulf of California with biologist Ed Ricketts. Drawn from the longer Sea of Cortez, it is a wonderful combination of science, philosophy, and high-spirited adventure.

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.

Cat Bohannon answers questions scientists should have been addressing for decades. With boundless curiosity and sharp wit, she covers the past 200 million years to explain the specific science behind the development of the female sex. Eve is not only a sweeping revision of human history, it's an urgent and necessary corrective for a world that has focused primarily on the male body for far too long. Bohannon's findings will completely change what you think you know about evolution.

Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals?

Named one of the top books of 2009 by the Times Literary Supplement (London), this controversial and compelling audiobook from Dr. Stephen C. Meyer presents a convincing new case for intelligent design (ID) based on revolutionary discoveries in science and DNA. Along the way Meyer argues that Charles Darwin's theory of evolution as expounded in The Origin of Species did not, in fact, refute ID.

At first glance, human history is full of remarkable feats of intelligence. We invented writing. Produced incredible achievements in music, the arts, and the sciences. We’ve built sprawling cities and traveled across oceans—and space—and expanded to every part of the globe. Yet, human exceptionalism can be a double-edged sword. With our unique cognitive prowess comes severe consequences, including existential angst, violence, discrimination, and the creation of a world teetering towards climate catastrophe. Understood side-by-side, human exceptionalism begins to look more like a curse.

On September 6, 2007, an African Grey parrot named Alex died prematurely at age 31. His last words to his owner, Irene Pepperberg, were "You be good. I love you." What would normally be a quiet, very private event was, in Alex's case, headline news. Over the 30 years they had worked together, Alex and Irene had become famous - two pioneers who opened an unprecedented window into the hidden yet vast world of animal minds.

While plenty of entertaining books have been written about the history of alcohol and other intoxicants, none have offered a comprehensive, convincing answer to the basic question of why humans want to get high in the first place. Drunk elegantly cuts through the tangle of urban legends and anecdotal impressions that surround our notions of intoxication to provide the first rigorous, scientifically grounded explanation for our love of alcohol.

What if animals and humans could speak to one another? Tom Mustill—the nature documentarian who went viral when a thirty-ton humpback whale breached onto his kayak—asks this question in his thrilling investigation into whale science and animal communication.

Published in 2005, The Biology of Belief transformed our understanding of what shapes human life. In this series of unscripted talks, Dr. Bruce H. Lipton unpacks the most salient points of his groundbreaking book to reveal how we can change our perceptions, our behaviors, and even our health to live the life we really want.

David Quammen's book, The Song of the Dodo, is a brilliant, stirring work, breathtaking in its scope, far-reaching in its message - a crucial book in precarious times, which radically alters the way in which we understand the natural world and our place in that world. It's also a book full of entertainment and wonders. In The Song of the Dodo, we follow Quammen's keen intellect through the ideas, theories, and experiments of prominent naturalists of the last two centuries.

Does science discredit the Bible, God, religious faith? Absolutely not, says Dr. Michael Guillen, former Harvard physics instructor and Emmy-winning ABC News science editor. In Amazing Truths, he uses his entertaining, down-to-earth storytelling skills to reveal 10 astonishing truths affirmed by both ancient Scripture and modern science.

In the tradition of Rachel Carson’s groundbreaking environmental classic Silent Spring, an award-winning entomologist and conservationist explains the importance of insects to our survival and offers a clarion call to avoid a looming ecological disaster of our own making.

It seems likely that scientists will someday discover how life can emerge on habitable planets like the early Earth and Mars. In Origin of Life: What Everyone Needs to Know, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections.

Jellyfish are an enigma. They have no centralized brain, but they see and feel and react to their environment in complex ways. They look simple, yet their propulsion systems are so advanced that engineers are just learning how to mimic them. They produce some of the deadliest toxins on the planet and still remain undeniably alluring. Long ignored by science, they may be a key to ecosystem stability. Juli Berwald's journey into the world of jellyfish is a personal one.

"El cerebro vive en un cuarto oscuro". "Tal es el gran misterio al que nos enfrentamos", afirma Arsuaga en este libro en el que el sapiens y el neandertal afrontan el mayor desafío de su proyecto en común, el más complejo, el que supone abrir una puerta a lo ignorado. Vivimos con la paradoja de que, pese a los avances de la neurociencia en los últimos años, el cerebro, que rige nuestra conexión con el mundo, continúa siendo el gran desconocido.

Hay fever. Peanut allergies. Eczema. Either you have an allergy or you know someone who does. Billions of people worldwide—an estimated 30 to 40 percent of the global population—have some form of allergy. Even more concerning, over the last decade the number of people diagnosed with an allergy has been steadily increasing, placing an ever-growing medical burden on individuals, families, communities, and healthcare systems. Medical anthropologist Theresa MacPhail, herself an allergy sufferer whose father died of a bee sting, set out to understand why.

The Strange Order of Things is a pathbreaking investigation into homeostasis, the condition that regulates human physiology within the range that makes possible not only the survival but also the flourishing of life. Antonio Damasio makes clear that we descend biologically, psychologically, and even socially from a long lineage that begins with single living cells; that our minds and cultures are linked by an invisible thread to the ways and means of ancient unicellular life and other primitive life-forms.

Since the dawn of recorded history, humans have felt a kinship with the sleek and beautiful dolphin, an animal whose playfulness, sociability, and intelligence seem like an aquatic mirror of mankind. In recent decades, we have learned that dolphins recognize themselves in reflections, count, grieve, adorn themselves, feel despondent, rescue one another (and humans), deduce, infer, seduce, form cliques, throw tantrums, and call themselves by name.
