El origen de las especies es un libro de Charles Darwin publicado el 24 de noviembre de 1859, considerado uno de los trabajos precursores de la literatura científica y el fundamento de la teoría de la biología evolutiva. Presentó pruebas de que la diversidad de la vida surgió de la descendencia común a través de un patrón ramificado de evolución. Darwin incluyó las pruebas que reunió en su expedición en el viaje del Beagle en la década de 1830 y sus descubrimientos posteriores mediante la investigación, la correspondencia y la experimentación.

If fresh water is to be treasured, the Great Lakes are the mother lode. No bodies of water can compare to them. One of them, Superior, is the largest lake on earth, and the five lakes together contain a fifth of the world's supply of standing fresh water. Their surface area of 95,000 square miles is greater than New York, New Jersey, Connecticut, Massachusetts, Vermont, New Hampshire, and Rhode Island combined. They are so vast that they dominate much of the geography, climate, and history of North America. In one way or another, they affect the lives of tens of millions.

In What Makes Olga Run? Bruce Grierson explores what the wild success of a 94-year-old track star can tell us about how our bodies and minds age. Olga Kotelko is not your average 94-year-old. She not only looks and acts like a much younger woman, she holds over 23 world records in track and field, 17 in her current 90 to 95 category. Convinced that this remarkable woman could help unlock many of the mysteries of aging, Grierson set out to uncover what it is that's driving Olga.

Studying zoology made Lucy Cooke feel like a sad freak. Not because she loved spiders or would root around in animal feces: All her friends shared the same curious kinks. The problem was her sex. Being female meant she was, by nature, a loser. Since Charles Darwin, evolutionary biologists have been convinced that the males of the animal kingdom are the interesting ones—dominating and promiscuous, while females are dull, passive, and devoted. But Cooke tells a new story.

We play games to learn about the world, to understand our minds and the minds of others, and to make predictions about the future. Games are an essential aspect of humanity and a powerful tool for modeling reality. They’re also a lot of fun. But games can be dangerous, especially when we mistake the model worlds of games for reality itself and let gamification co-opt human decision making. Playing with Reality explores the riveting history of games since the Enlightenment.

The extraordinary Siddhartha Mukherjee has written a biography of the gene as deft, brilliant, and illuminating as his extraordinarily successful biography of cancer. Weaving science, social history, and personal narrative to tell us the story of one of the most important conceptual breakthroughs of modern times, Mukherjee animates the quest to understand human heredity and its surprising influence on our lives, personalities, identities, fates, and choices.

With its quaint villages, local restaurants serving up lobster rolls, and miles and miles of warm, sandy beaches, Cape Cod, Massachusetts, is famous for being America’s carefree seaside getaway. But in August 2012, the first confirmed shark attack in almost eighty years occurred in the region. As shark sightings quickly began to increase on Cape Cod and elsewhere and large beachside billboards warning about the growing shark population became a common sight, a boogie boarder died after being attacked by a great white shark in Cape Cod’s shallow waters.

There are many routes to mental well-being. In this groundbreaking book, neuroscientist Camilla Nord offers a fascinating tour of the scientific developments that are revolutionizing the way we think about mental health, showing why and how events—and treatments—can affect people in such different ways. In The Balanced Brain, Nord explains how our brain constructs our sense of mental health—actively striving to maintain balance in response to our changing circumstances.

With stories that entertain as much as they inform, renowned evolutionist David Sloan Wilson outlines the basic principles of evolution and shows how, when properly understood, they can illuminate the length and breadth of creation, from the origin of life to the nature of religion.

Author Brian Switek is a charming and enthusiastic osteological raconteur. In this natural and cultural history of bone, he explains where our skeletons came from, what they do inside us, and what others can learn about us when these wondrous assemblies of mineral and protein are all we've left behind.

Journalist Jeff Bercovici spent extensive time with professional and Olympic athletes, coaches, and doctors to find how today's sports superstars seemed to be able to defy the limits of physical aging that inevitably sideline their competitors. Through fascinating profiles and first-person anecdotes, Bercovici illuminates the science and strategies extending the careers of elite older athletes, uncovers the latest advances in fields from nutrition to brain science to virtual reality, and offers empowering insights about how the rest of us can find peak performance at any age.

The story of the "Lentil Underground" begins on a 280-acre homestead rooted in America's Great Plains: the Oien family farm. Forty years ago, corporate agribusiness told small farmers like the Oiens to "get big or get out." But 27-year-old David Oien decided to take a stand, becoming the first in his conservative Montana county to plant a radically different crop: organic lentils. Unlike the chemically dependent grains American farmers had been told to grow, lentils make their own fertilizer and tolerate variable climates, so their farmers aren't beholden to industrial methods.

Revealing how panspermia offers answers to some of humanity’s longstanding questions about the origins of life, the authors discuss the impact this shift in understanding will have on our relationship with the Earth and on culture, history, and religion. And perhaps the most dramatic ramification of all is that acceptance of panspermia means acceptance that Earth is not unique - that other life-filled planets exist and intelligent life is common in the Universe. Not only did we come from space, but we are not alone.

Having worked on numerous high-profile genetic investigations, including one focused on the famed Iceman of the Italian Alps, Bryan Sykes has become a premier authority on human genetics. In DNA USA, Sykes examines the unique fabric of the population of the United States - one of the world’s most genetically variegated countries. His fascinating discoveries offer new insights into the biological profile of the great melting pot.

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.

A significant number of Americans, especially evangelical Christians, believe Earth and humankind were created in their present form sometime in the last 10,000 years or so - the rationale being that this is (presumably) the story told in the book of Genesis. Within that group, any threatening scientific evidence that suggests otherwise is rejected or, when possible, retrofitted into a creationist worldview.

Sy Montgomery's popular 2011 Orion magazine piece, "Deep Intellect", about her friendship with a sensitive, sweet-natured octopus named Athena and the grief she felt at her death, went viral, indicating the widespread fascination with these mysterious, almost alien-like creatures. Since then Sy has practiced true immersion journalism, from New England aquarium tanks to the reefs of French Polynesia and the Gulf of Mexico, pursuing these wild, solitary shape-shifters.

When ecologist Carl Safina and his wife, Patricia, took in a near-death baby owl, they expected that, like other wild orphans they'd rescued, she'd be a temporary presence. But Alfie's feathers were not growing correctly, requiring prolonged care. As Alfie grew and gained strength, she became a part of the family, joining a menagerie of dogs and chickens and making a home for herself in the backyard.
