We know much about our history from bones and DNA, but these studies do not tell us about the characteristics that are not preserved in the fossil record―the fleshy parts and behaviors. Looking Down the Tree applies evolutionary principles to understand the history of our species and the pressures of natural selection which led to our unique appearance and behaviors. Cruzan draws upon evidence from fossils, genomics, phylogenetics, coalescence theory.

A cutting-edge guide to the psychology and neuroscience of spiritual experiences.

Since 2010, it has been possible to determine a person's genetic makeup in a matter of days at an accessible cost for many millions of people. Along with this technological breakthrough there has emerged a movement to use this information to help prospective parents "eliminate preventable genetic disease". As the prospect of systematically excluding the appearance of unwanted mutations in our children comes within reach, David B. Goldstein examines the possible consequences from these types of choices.

In this Very Short Introduction, Paul B. Wignall looks at the causes and nature of extinctions, past and present, and the factors that can make a species vulnerable. Summarizing what we know about all of the major and minor extinction events, he examines some of the greatest debates in modern science, such as the relative role of climate and humans in the death of the Pleistocene megafauna, including mammoths and giant ground sloths, and the roles that global warming, ocean acidification, and deforestation are playing in present-day extinctions.

Why is the world the way it is? How did we get here? Does everything happen for a reason, or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world.

Ignác Semmelweis is remembered for the now-commonplace notion that doctors must wash their hands before examining patients. In mid-19th century Vienna, however, this was a subversive idea. With deaths from childbed fever exploding, Semmelweis discovered that doctors themselves were spreading the disease. While his simple reforms worked immediately - childbed fever in Vienna all but disappeared - they brought down upon Semmelweis the wrath of the establishment, and led to his tragic end.

How does life work? How does nature produce the right numbers of zebras and lions on the African savanna, or fish in the ocean? How do our bodies produce the right numbers of cells in our organs and bloodstream? In The Serengeti Rules, award-winning biologist and author Sean B. Carroll tells the stories of the pioneering scientists who sought the answers to such simple yet profoundly important questions.

La Terra è il pianeta blu. Ma la nostra conoscenza del mare è spesso approssimativa e superficiale. L'autrice ci guida alla scoperta dei suoi abitanti adottando un punto di vista tutto particolare: il loro! Scopriremo così come si muovono, in che modo si corteggiano e riproducono, come percepiscono quanto li circonda e interagiscono tra loro. Nel mare troviamo un gran numero di specie viventi, molte ancora da scoprire. Conoscere la ricchezza e la fragilità del mondo sommerso significa anche porsi il problema di tutelarlo e difenderlo da un uso sconsiderato delle sue risorse.

Smallpox, the only infectious disease to have been eradicated, was one of the most terrifying of human scourges. It covered the skin with hideous, painful boils, killed a third of its victims, and left the survivors disfigured for life. In this riveting, often terrifying look at the history of smallpox, Jonathan B. Tucker tells the story of this deadly disease, the heroic efforts to eradicate it worldwide, and the looming dangers it still poses today.

Ever since Carl Linnaeus's binomial system of scientific names was adopted in the 18th century, scientists have been eponymously naming organisms in ways that both honor and vilify their namesakes. This charming, informative, and accessible history examines the fascinating stories behind taxonomic nomenclature, from Linnaeus himself naming a small and unpleasant weed after a rival botanist to the recent influx of scientific names based on pop-culture icons-including David Bowie's spider, Frank Zappa's jellyfish, and Beyonce's fly.

Larry S. Sherman, a neuroscientist and lifelong musician, and Dennis Plies, a professional musician and teacher, collaborate to show how our brains and music work in harmony. They consider music in all the ways we encounter it—teaching, learning, practicing, listening, composing, improvising, and performing—in terms of neuroscience as well as music pedagogy, showing how the brain functions and even changes in the process. Every Brain Needs Music draws on leading behavioral, cellular, and molecular neuroscience research as well as surveys of more than a hundred musical people.

Birding for Boomers is a friendly, accessible, and humorous guide to discovering the joys of bird watching. Beginning birders of all ages will get answers to every question they may have, like which birds like feeders, the difference between a finch and a flicker, or which birding app to use. The guide also helps birders plan everything from local explorations to exciting "bird-cations."

We’re Full of Plastic is a deep dive into one of the most urgent and overlooked environmental and health crises of our time: the invasion of microplastics into the human body. According to a landmark study, the average person may ingest up to 5 grams of plastic each week—roughly the size of a credit card. Drawing on cutting-edge scientific studies, this eye-opening book reveals how plastic pollution is no longer just a problem for oceans and landfills—it's a problem inside us.

In the 200 years since we discovered that microbes cause infectious diseases, we've battled to keep them at bay. But a recent explosion of scientific knowledge has led to undeniable evidence that early exposure to these organisms is beneficial to our children's well-being. Our current emphasis on hyper-cleanliness is taking a toll on our children's lifelong health. This engaging and important book explains how the millions of microbes that live in our bodies influence childhood development.

In this series of 24 fascinating lectures, an acclaimed teacher and psychologist gives you a bio-psychological perspective on both the way we humans navigate and react to the world around us and an understanding of the ways in which that process is ever-changing.

While politicians, entrepreneurs, and even school children could tell you that sustainability is an important and nearly universal value, many of them, and many of us, may struggle to define the term, let alone trace its history. What is sustainability? Is it always about the environment? What science do we need to fully grasp what it requires? What does sustainability mean for business? How can governments plan for a sustainable future?

What is life? Many scientists believe life can be reduced to ‘mechanistic’ factors, such as genes and information codes. Yet there is a growing army of scientists, philosophers and artists who reject this view. The gene metaphor is not only too simplistic but deeply misleading. If there is a way to reduce life to a single principle, that principle must acknowledge the creativity of life, turning genetic determinism on its head.

I nostri geni non sono scolpiti nella pietra e i nostri fattori ereditari non sono un' "impronta digitale" fissa e immodificabile. Un essere umano infatti è molto più della somma dei suoi geni. Tutto quello che mangiamo, facciamo e sentiamo, tutto ciò che ci accade può influire sull'attività del DNA, a prescindere dalla configurazione genetica con la quale nasciamo. L'epigenetica, cioè la branca della genetica che si occupa di indagare le variazioni dell'espressione del nostro DNA, ci porta infatti una buona notizia: tali variazioni sono reversibili.
