Scientists are confident that there is alien life across the universe yet we have not moved beyond our perception of 'aliens' as Hollywood stereotypes. The time has come to abandon our fixation on alien monsters and place our expectations on solid scientific footing.Using his own expert understanding of life on Earth and Darwin's theory of evolution - which applies throughout the universe - Cambridge zoologist Dr Arik Kershenbaum explains what alien life must be like: how these creatures will move, socialise and communicate.For example, by observing fishes whose electrical pulses indicate social status, we can see that other planets might allow for communication by electricity. As there was evolutionary pressure to wriggle along a sea floor, Earthling animals tend to have left/right symmetry; on planets where creatures evolved mid-air or in soupy tar they might be lacking any symmetry at all.Might there be an alien planet with supersonic animals? Will they scream with fear, act honestly, or have technology? Is the universe swarming with robots? Dr Kershenbaum uses cutting-edge science to paint an entertaining and compelling picture of extra-terrestrial life.The Zoologist's Guide to the Galaxy is the story of how life really works, on Earth and in space.***'If you don't want to be surprised by extraterrestrial life, look no further than this lively overview of the laws of evolution that have produced life on earth' - Frans de Waal, author of Mama's Last Hug - Animal Emotions and What They Tell Us about Ourselves'A fun, and thoroughly biological, exploration of possible and impossible alien beings. If you'd love to know what real aliens from other planets might really be like, this is the book for you' - Susan Blackmore, author of Seeing Myself'Surveying the deep-time of evolution on Earth and his own cutting-edge research into animal communication, Kershenbaum provides a fascinating insight into the deepest of questions: what might an alien actually look like'- Lewis Dartnell, author of Origins'Arik Kershenbaum takes us on a joyous voyage of animal diversity and illustrates the singular importance of natural selection in explaining life - here on Earth - and what will likely be discovered throughout the galaxy.

    A deep vibration shook the entire island. Jets of steam and ash emanated from the summit, followed by an explosion louder than any sound heard by Homo sapiens since our species evolved on Earth. The eruption of the Toba supervolcano released the energy of a million tons of explosives; seven hundred cubic miles of magma spewed outward in an explosion forty times larger than the largest hydrogen bomb and more than a thousand times as powerful as the Krakatau eruption in 1883. So much ash and debris was injected into the stratosphere that it partially blocked the sun's radiation and caused global temperatures to drop by five to nine degrees. It took a full decade for Earth to recover to its pre-eruption temperatures.When Humans Nearly Vanished presents the controversial argument that the Toba catastrophe nearly wiped out the human race, leaving only about a thousand to ten thousand breeding pairs of humans worldwide. Human genes today show evidence of a "genetic bottleneck," an effect seen when a population of organisms becomes so small that their genetic diversity is greatly reduced. This group of survivors could be the ancestors of all humans alive today. Donald R. Prothero explores the geological and biological evidence supporting the Toba bottleneck theory; reveals how the explosion itself was discovered; and offers insight into how the world changed afterward and what might happen if such an eruption occurred today. Prothero's riveting account of this calamitous supervolcanic explosion is not to be missed.

    Exploring the history of cannibalism, the neurology of people who are sexually attracted to animals, the evolution of human body fluids, the science of homosexuality, and serious questions about life and death, Bering astutely covers a generous expanse of our kaleidoscope of quirks and origins.With his characteristic irreverence and trademark cheekiness, Bering leaves no topic unturned or curiosity unexamined, and he does it all with an audaciously original voice. Whether you're interested in the psychological history behind the many facets of sexual desire or the evolutionary patterns that have dictated our current mystique and phallic physique, Why Is the Penis Shaped Like That? is bound to create lively discussion and debate for years to come.

    But in The Music of Life, world renowned physiologist Denis Noble argues that, to truly understand life, we must look beyondthe selfish gene to consider life on a much wider variety of levels. Life, Noble asserts, is a kind of music, a symphonic interplay between genes, cells, organs, body, and environment. He weaves this musical metaphor throughout this personal and deeply lyrical work, illuminating ideas that might otherwise be daunting to non-scientists. In elegant prose, Noblesets out a cutting-edge alternative to the gene's eye view, offering a radical switch of perception in which genes are seen as prisoners and the organism itself is a complex system of many interacting levels. In his more expansive view, life emerges as a process, the ebb and flow of activity in anintricate web of connections. He introduces readers to the realm of systems biology, a field that has been growing in strength in the past decade. Noble, himself one of the founders of this field, argues modern systems biology may be the view we need to adopt to gain a deeper understanding of thenature of life. Drawing on his experiences in his research on the heartbeat, and on evolutionary biology, development, medicine, philosophy, linguistics, and Chinese culture, Noble presents us with a profound and very modern reflection on the nature of life.

    She puts the English national character under her anthropological microscope, and finds a strange and fascinating culture, governed by complex sets of unspoken rules and byzantine codes of behaviour. The rules of weather-speak. The ironic-gnome rule. The reflex apology rule. The paranoid-pantomime rule. Class indicators and class anxiety tests. The money-talk taboo and many more ...Through a mixture of anthropological analysis and her own unorthodox experiments (using herself as a reluctant guinea-pig), Kate Fox discovers what these unwritten behaviour codes tell us about Englishness.

    But things didn't turn out that way. For a start, we turned out to have far fewer genes than originally thought - just over 20,000, the same sort of number as a fruit fly or worm. What's more, the proportionof DNA consisting of genes coding for proteins was a mere 2%. So, was the rest of the genome accumulated 'junk'?Things have changed since those early heady days of the Human Genome Project. But the emerging picture is if anything far more exciting. In this book, John Parrington explains the key features that are coming to light - some, such as the results of the international ENCODE programme, still much debated and controversial in their scope. He gives an outline of the deeper genome, involving layers of regulatory elements controlling and coordinating the switching on and off of genes; the impact ofits 3D geometry; the discovery of a variety of new RNAs playing critical roles; the epigenetic changes influenced by the environment and life experiences that can make identical twins different and be passed on to the next generation; and the clues coming out of comparisons with the genomes ofNeanderthals as well as that of chimps about the development our species. We are learning more about ourselves, and about the genetic aspects of many diseases. But in its complexity, flexibility, and ability to respond to environmental cues, the human genome is proving to be far more subtle than we ever imagined.

    The majority view is that life began with replicating molecules, the precursors of modern genes. The minority belief is that random populations of molecules evolved metabolic activities before exact replication existed and that natural selection drove the evolution of cells toward greater complexity for a long time without the benefit of genes. Dyson analyzes both of these theories with reference to recent important discoveries by geologists and chemists, aiming to stimulate new experiments that could help decide which theory is correct. This second edition covers the impact revolutionary discoveries such as the existence of ribozymes, enzymes made of RNA; the likelihood that many of the most ancient creatures are thermophilic, living in hot environments; and evidence of life in the most ancient of all terrestrial rocks in Greenland have had on our ideas about how life began. It is a clearly written, fascinating book that will appeal to anyone interested in the origins of life.

    Two scientists explore the potential of a revolutionary genetics technology capable of easily and affordably manipulating DNA in human embryos to prevent specific diseases, addressing key concerns about related ethical and societal repercussions.

    Mainstream science--as well as religious and cultural institutions--has maintained that men and women evolved in families in which a man's possessions and protection were exchanged for a woman's fertility and fidelity. But this narrative is collapsing. Fewer and fewer couples are getting married, and divorce rates keep climbing as adultery and flagging libido drag down even seemingly solid marriages.How can reality be reconciled with the accepted narrative? It can't be, according to renegade thinkers Christopher Ryan and Cacilda Jethá. While debunking almost everything we "know" about sex, they offer a bold alternative explanation in this provocative and brilliant book.Ryan and Jethá's central contention is that human beings evolved in egalitarian groups that shared food, child care, and, often, sexual partners. Weaving together convergent, frequently overlooked evidence from anthropology, archaeology, primatology, anatomy, and psychosexuality, the authors show how far from human nature monogamy really is. Human beings everywhere and in every era have confronted the same familiar, intimate situations in surprisingly different ways. The authors expose the ancient roots of human sexuality while pointing toward a more optimistic future illuminated by our innate capacities for love, cooperation, and generosity.With intelligence, humor, and wonder, Ryan and Jethá show how our promiscuous past haunts our struggles over monogamy, sexual orientation, and family dynamics. They explore why long-term fidelity can be so difficult for so many; why sexual passion tends to fade even as love deepens; why many middle-aged men risk everything for transient affairs with younger women; why homosexuality persists in the face of standard evolutionary logic; and what the human body reveals about the prehistoric origins of modern sexuality.In the tradition of the best historical and scientific writing, Sex at Dawn unapologetically upends unwarranted assumptions and unfounded conclusions while offering a revolutionary understanding of why we live and love as we do.

    Widely praised and much-discussed, this classic book explores how cooperation can emerge in a world of self-seeking egoists—whether superpowers, businesses, or individuals—when there is no central authority to police their actions. The problem of cooperation is central to many different fields. Robert Axelrod recounts the famous computer tournaments in which the “cooperative” program Tit for Tat recorded its stunning victories, explains its application to a broad spectrum of subjects, and suggests how readers can both apply cooperative principles to their own lives and teach cooperative principles to others.

    Lehninger Principles of Biochemistry, Fourth Edition brings clarity and coherence to an often unwieldy discipline, while incorporating the field's most important recent developments and applications.

    The Lucifer Priciple is a revolutionary work that explores the intricate relationships among genetics, human behavior, and culture to put forth the thesis that “evil” is a by-product of nature’s strategies for creation and that it is woven into our most basic biological fabric.

    Nature’s many innovations—some uncannily perfect—call for natural principles that accelerate life’s ability to innovate.”Darwin’s theory of natural selection explains how useful adaptations are preserved over time. But the biggest mystery about evolution eluded him. As genetics pioneer Hugo de Vries put it, “natural selection may explain the survival of the fittest, but it cannot explain the arrival of the fittest.”Can random mutations over a mere 3.8 billion years really be responsible for wings, eyeballs, knees, camouflage, lactose digestion, photosynthesis, and the rest of nature’s creative marvels? And if the answer is no, what is the mechanism that explains evolution’s speed and efficiency?In Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over fifteen years of research to present the missing piece in Darwin's theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take.Consider the Arctic cod, a fish that lives and thrives within six degrees of the North Pole, in waters that regularly fall below 0 degrees. At that temperature, the internal fluids of most organisms turn into ice crystals. And yet, the arctic cod survives by producing proteins that lower the freezing temperature of its body fluids, much like antifreeze does for a car’s engine coolant. The invention of those proteins is an archetypal example of nature’s enormous powers of creativity. Meticulously researched, carefully argued, evocatively written, and full of fascinating examples from the animal kingdom, Arrival of the Fittest offers up the final puzzle piece in the mystery of life’s rich diversity.
