 There's a silent epidemic in Western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis.

Now in a third edition, Robert M. Sapolsky's acclaimed and successful Why Zebras Don't Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress. As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear-and the ones that plague us now-are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer.

Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

We are capable of savage acts of violence but also spectacular feats of kindness: is one side of our nature destined to win out over the other? Every act of human behaviour has multiple layers of causation, spiralling back seconds, minutes, hours, days, months, years, even centuries, right back to the dawn of time and the origins of our species. In the epic sweep of history, how does our biology affect the arc of war and peace, justice and persecution? How have our brains evolved alongside our cultures?

The existence of free will - our ability to choose between one course of action and another, to determine our own destiny - is a foundation stone of Western society, dictating our notions of fairness and justice, punishment and reward, our very identity as individuals and humans. But as world-renowned scientist Robert Sapolsky shows, there is not a shred of evidence to suggest that free will exists, even while everything in our biology leads us to believe that it does.

Feeling stressed? You're not alone. Stress is an inherent aspect of life that can have tremendous negative effects on your mental and physical health. This makes coping with stress a critical part of how well we live.Once you understand the inner workings of your stress response system, you'll possess powerful knowledge that will help you understand and better deal with this common aspect of your busy life.

When are we responsible for our own actions, and when are we in the grip of biological forces beyond our control? What determines who we fall in love with? The intensity of our spiritual lives? The degree of our aggressive impulses? These questions fall into the scientific province of behavioral biology, the field that explores interactions between the brain, mind, body, and environment that have a surprising influence on how we behave.

Discover this remarkable account of 21 years in remote Kenya with a troop of Savannah baboons from the New York Times best-selling author of Behave. Brooklyn-born Robert Sapolsky grew up wishing he could live in the primate diorama in the Museum of Natural History. At school he wrote fan letters to primatologists and even taught himself Swahili, all with the hope of one day joining his primate brethren in Africa. But when, at the age of 21, Sapolky's dream finally comes true, he discovers that the African bush bears little resemblance to the tranquillity of a museum. 

Un examen minucioso del comportamiento humano y una respuesta a la pregunta: ¿por qué hacemos las cosas que hacemos? Sapolsky analiza los factores en juego, desde el momento previo hasta los factores arraigados en la historia de nuestra especie y su legado evolutivo. Partiendo de una explicación neurobiológica -¿qué sucedió en el cerebro de una persona un segundo antes de que se comportara así?, ¿qué visión, sonido u olor hicieron que el sistema nervioso produjera ese comportamiento?-, pasamos a pensar en el mundo sensorial y la endocrinología.

En la tradición de Jane Goodall y Dian Fossey, Robert Sapolsky, uno de los divulgadores científicos más reconocidos en la actualidad, cuenta la fascinante historia de cómo dejó las comodidades de la universidad para compartir durante más de dos décadas su trabajo de campo con una tropa de traviesos babuinos en la sabana africana. Sólo un joven idealista podía aterrizar en el corazón de Kenia esperando encontrar ahí una versión animada de lo que había visto y estudiado hasta entonces en el Museo de Ciencias Naturales de Nueva York.
