“Surprising. Impressive. Cannibalism restores my faith in humanity.” —Sy Montgomery, The New York Times Book Review For centuries scientists have written off cannibalism as a bizarre phenomenon with little biological significance. Its presence in nature was dismissed as a desperate response to starvation or other life-threatening circumstances, and few spent time studying it. A taboo subject in our culture, the behavior was portrayed mostly through horror movies or tabloids sensationalizing the crimes of real-life flesh-eaters. But the true nature of cannibalism--the role it plays in evolution as well as human history--is even more intriguing (and more normal) than the misconceptions we’ve come to accept as fact. In Cannibalism: A Perfectly Natural History,zoologist Bill Schutt sets the record straight, debunking common myths and investigating our new understanding of cannibalism’s role in biology, anthropology, and history in the most fascinating account yet written on this complex topic. Schutt takes readers from Arizona’s Chiricahua Mountains, where he wades through ponds full of tadpoles devouring their siblings, to the Sierra Nevadas, where he joins researchers who are shedding new light on what happened to the Donner Party--the most infamous episode of cannibalism in American history. He even meets with an expert on the preparation and consumption of human placenta (and, yes, it goes well with Chianti). Bringing together the latest cutting-edge science, Schutt answers questions such as why some amphibians consume their mother’s skin; why certain insects bite the heads off their partners after sex; why, up until the end of the twentieth century, Europeans regularly ate human body parts as medical curatives; and how cannibalism might be linked to the extinction of the Neanderthals. He takes us into the future as well, investigating whether, as climate change causes famine, disease, and overcrowding, we may see more outbreaks of cannibalism in many more species--including our own.Cannibalism places a perfectly natural occurrence into a vital new context and invites us to explore why it both enthralls and repels us.

In 1980, the science world was stunned when a maverick team of researchers proposed that a massive meteor strike had wiped the dinosaurs and other fauna from the Earth 66 million years ago. Scientists found evidence for this theory in a “crater of doom” on the Yucatán Peninsula, showing that our planet had once been a target in a galactic shooting gallery. In Cataclysms, Michael R. Rampino builds on the latest findings from leading geoscientists to take “neocatastrophism” a step further, toward a richer understanding of the science behind major planetary upheavals and extinction events.
Rampino recounts his conversion to the impact hypothesis, describing his visits to meteor-strike sites and his review of the existing geological record. The new geology he outlines explicitly rejects nineteenth-century “uniformitarianism,” which casts planetary change as gradual and driven by processes we can see at work today. Rampino offers a cosmic context for Earth’s geologic evolution, in which cataclysms from above in the form of comet and asteroid impacts and from below in the form of huge outpourings of lava in flood-basalt eruptions have led to severe and even catastrophic changes to the Earth’s surface. This new geology sees Earth’s position in our solar system and galaxy as the keys to understanding our planet’s geology and history of life. Rampino concludes with a controversial consideration of dark matter’s potential as a triggering mechanism, exploring its role in heating Earth’s core and spurring massive volcanism throughout geologic time.

The passenger pigeon, the great auk, the Tasmanian tiger—the memory of these vanished species haunts the fight against extinction. Seeking to save other creatures from their fate in an age of accelerating biodiversity loss, wildlife advocates have become captivated by a narrative of heroic conservation efforts. A range of technological and policy strategies, from the traditional, such as regulations and refuges, to the novel—the scientific wizardry of genetic engineering and synthetic biology—seemingly promise solutions to the extinction crisis.
In The Fall of the Wild, Ben A. Minteer calls for reflection on the ethical dilemmas of species loss and recovery in an increasingly human-driven world. He asks an unsettling but necessary question: Might our well-meaning efforts to save and restore wildlife pose a threat to the ideal of preserving a world that isn’t completely under the human thumb? Minteer probes the tension between our impulse to do whatever it takes and the risk of pursuing strategies that undermine our broader commitment to the preservation of wildness. From collecting wildlife specimens for museums and the wilderness aspirations of zoos to visions of “assisted colonization” of new habitats and high-tech attempts to revive long-extinct species, he explores the scientific and ethical concerns vexing conservation today. The Fall of the Wild is a nuanced treatment of the deeper moral issues underpinning the quest to save species on the brink of extinction and an accessible intervention in debates over the principles and practice of nature conservation.

The key ideas in Psychology explained, with colour illustrations, in half a minute. Pavlov's Dogs, Psychoanalysis, Milgram's Obedience Study, and Beck's Cognitive Therapy? Sure, you know what they all mean. That is, you've certainly heard of them. But do you know enough about these psychology theories to join a dinner party debate or dazzle the bar with your knowledge? 30-Second Psychology takes the top 50 strands of thinking in this fascinating field, and explains them to the general reader in half a minute, using nothing more than two pages, 300 words, and one picture. The inner workings of the human mind will suddenly seem a lot more fun, and along the way we meet many of the luminaries in the field, including William James, Aaron Beck, and (of course) Sigmund Freud. From Behaviorism to Cognitivism, what better way to get a handle on your inner demons?
