The Power of Music
Elena Mannes - 2011
Only recently has science sought in earnest to understand and explain this impact. One remarkable recent study, analyzing the cries of newborns, shows that infants' cries contain common musical intervals, and children tease each other in specific, singsong ways no matter where in the world they live. Physics experiments show that sound waves can physically change the structure of a material; musician and world-famous conductor Daniel Barenboim believes musical sound vibrations physically penetrate our bodies, shifting molecules as they do. The Power of Music follows visionary researchers and accomplished musicians to the crossroads of science and culture, to discover: how much of our musicality is learned and how much is innate? Can examining the biological foundations of music help scientists unravel the intricate web of human cognition and brain function? Why is music virtually universal across cultures and time-does it provide some evolutionary advantage? Can music make people healthier? Might music contain organizing principles of harmonic vibration that underlie the cosmos itself?
Supernormal Stimuli: How Primal Urges Overran Their Evolutionary Purpose
Deirdre Barrett - 2010
Our instincts—for food, sex, or territorial protection— evolved for life on the savannahs 10,000 years ago, not in today’s world of densely populated cities, technological innovations, and pollution. We now have access to a glut of larger-than-life objects, from candy to pornography to atomic weapons—that gratify these gut instincts with often-dangerous results. Animal biologists coined the term “supernormal stimuli” to describe imitations that appeal to primitive instincts and exert a stronger pull than real things, such as soccer balls that geese prefer over eggs. Evolutionary psychologist Deirdre Barrett applies this concept to the alarming disconnect between human instinct and our created environment, demonstrating how supernormal stimuli are a major cause of today’s most pressing problems, including obesity and war. However, Barrett does more than show how unfettered instincts fuel dangerous excesses. She also reminds us that by exercising self-control we can rein them in, potentially saving ourselves and civilization. 55 illustrations.
Shrinking the Cat: Genetic Engineering Before We Knew About Genes
Sue Hubbell - 2001
Focusing on four specific examples — corn, silkworms, domestic cats, and apples — she traces the histories of species that have been fundamentally altered over the centuries by the whims and needs of people.
Does Altruism Exist?: Culture, Genes, and the Welfare of Others
David Sloan Wilson - 2015
From an evolutionary viewpoint, Wilson argues, altruism is inextricably linked to the functional organization of groups. “Groups that work” undeniably exist in nature and human society, although special conditions are required for their evolution. Humans are one of the most groupish species on earth, in some ways comparable to social insect colonies and multi-cellular organisms. The case that altruism evolves in all social species is surprisingly simple to make. Yet the implications for human society are far from obvious. Some of the most venerable criteria for defining altruism aren’t worth caring much about, any more than we care much whether we are paid by cash or check. Altruism defined in terms of thoughts and feelings is notably absent from religion, even though altruism defined in terms of action is notably present. The economic case for selfishness can be decisively rejected. The quality of everyday life depends critically on people who overtly care about the welfare of others. Yet, like any other adaptation, altruism can have pathological manifestations. Wilson concludes by showing how a social theory that goes beyond altruism by focusing on group function can help to improve the human condition.
The Second Intelligent Species: How Humans Will Become as Irrelevant as Cockroaches
Marshall Brain - 2015
We currently see no evidence of any kind indicating that extraterrestrials exist outside of our solar system. But at this moment, millions of engineers, scientists, corporations, universities and entrepreneurs are racing to create the second intelligent species right here on planet earth. And we can see the second intelligent species coming from all directions in the form of self-driving cars, automated call centers, chess-playing and Jeopardy-playing computers that beat all human players, airport kiosks, restaurant tablet systems, etc. The frightening thing is that these robots will soon be eliminating human jobs in startling numbers. The first wave of unemployed workers is likely to be a million truck drivers who are replaced by self-driving trucks. Pilots will be eliminated soon as well. Then, as new computer vision systems come online, we will see tens of millions of workers in retail stores, fast food restaurants and construction sites replaced by robots. Unless we take steps now to change the economy, we will soon have tens of millions of workers who are unemployed and seeking welfare because they will have no other choice. Marshall Brain's new book "The Second Intelligent Species: How Humans Will Become as Irrelevant as Cockroaches" explores how the future will unfold as the second intelligent species emerges. The book answers questions like: - How will new computer vision systems affect the job market? - How many people will become unemployed by the second intelligent species? - What will happen to millions of newly unemployed workers? - How can modern society and modern economies cope with run-away unemployment caused by robots? - What will happen when the first sentient, conscious computer appears? - What moral and ethical principles will guide the second intelligent species? - Why do we see no extraterrestrials in our universe? "The Second Intelligent Species" offers a unique and fascinating look at the future of the human race, and the choices we will need to make to avoid massive unemployment and poverty worldwide as intelligent machines start eliminating millions of jobs.
Twilight of the Mammoths: Ice Age Extinctions and the Rewilding of America
Paul S. Martin - 2005
In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age. Part paleontological adventure and part memoir, Twilight of the Mammoths presents in detail internationally renowned paleoecologist Paul Martin's widely discussed and debated "overkill" hypothesis to explain these mysterious megafauna extinctions. Taking us from Rampart Cave in the Grand Canyon, where he finds himself "chest deep in sloth dung," to other important fossil sites in Arizona and Chile, Martin's engaging book, written for a wide audience, uncovers our rich evolutionary legacy and shows why he has come to believe that the earliest Americans literally hunted these animals to death.As he discusses the discoveries that brought him to this hypothesis, Martin relates many colorful stories and gives a rich overview of the field of paleontology as well as his own fascinating career. He explores the ramifications of the overkill hypothesis for similar extinctions worldwide and examines other explanations for the extinctions, including climate change. Martin's visionary thinking about our missing megafauna offers inspiration and a challenge for today's conservation efforts as he speculates on what we might do to remedy this situation—both in our thinking about what is "natural" and in the natural world itself.
Deep: Freediving, Renegade Science, and What the Ocean Tells Us about Ourselves
James Nestor - 2014
This man was a freediver, and his amphibious abilities inspired Nestor to seek out the secrets of this little-known discipline. In Deep, Nestor embeds with a gang of extreme athletes and renegade researchers who are transforming not only our knowledge of the planet and its creatures, but also our understanding of the human body and mind. Along the way, he takes us from the surface to the Atlantic’s greatest depths, some 28,000 feet below sea level. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and seals who dive to depths below 2,400 feet for up to eighty minutes—deeper and longer than scientists ever thought possible. As strange as these phenomena are, they are reflections of our own species’ remarkable, and often hidden, potential—including echolocation, directional sense, and the profound physiological changes we undergo when underwater. Most illuminating of all, Nestor unlocks his own freediving skills as he communes with the pioneers who are expanding our definition of what is possible in the natural world, and in ourselves.
End of the Megafauna: The Fate of the World's Hugest, Fiercest, and Strangest Animals
Ross D.E. MacPhee - 2018
These great beasts, or “megafauna,” lived on every habitable continent and on many islands. With a handful of exceptions, all are now gone.What caused the disappearance of these prehistoric behemoths? No one event can be pinpointed as a specific cause, but several factors may have played a role. Paleomammalogist Ross D. E. MacPhee explores them all, examining the leading extinction theories, weighing the evidence, and presenting his own conclusions. He shows how theories of human overhunting and catastrophic climate change fail to account for critical features of these extinctions, and how new thinking is needed to elucidate these mysterious losses.Along the way, we learn how time is determined in earth history; how DNA is used to explain the genomics and phylogenetic history of megafauna—and how synthetic biology and genetic engineering may be able to reintroduce these giants of the past. Until then, gorgeous four-color illustrations by Peter Schouten re-create these megabeasts here in vivid detail.
The Living Shore: Rediscovering a Lost World
Rowan Jacobsen - 2009
He saw amazing sights, from the wildest, most breathtaking coasts to the smallest of marine creatures. Along the western side of Vancouver Island, Kingzett nosed into an isolated pocket beach where he found something unusual. Amid the mussels, barnacles, and clams were round oysters―Olympias. Kingzett noted their presence and paddled on. A decade later when he met Betsy Peabody, executive director of the Puget Sound Restoration Fund (PSRF), he learned that this once ubiquitous native oyster was in steep decline, and he knew that together they would return to this remote spot.Rowan Jacobsen, along with Kingzett, Peabody, and a small group of scientists from PSRF and the Nature Conservancy, set out last July to see if the Olys were still surviving―and if they were, what they could learn from them. The goal: to use their pristine natural beds, which have probably been around for millennia, as blueprints for the habitat restoration efforts in Puget Sound. The implications are vast. If Peabody and her team can bring good health back to Puget Sound by restoring the intertidal zones―the areas of land exposed during low tide and submerged during high tide, where oysters live―their research could serve as a model for saving the world's oceans.During a time when the fate of the oceans seems uncertain, Rowan Jacobsen has found hope in the form of a small shelled creature living in the lost world where all life began.
