Download or read book Evolution in the Dark written by Horst Wilkens and published by Springer. This book was released on 2017-05-25 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides fascinating insights into the development and genetics of evolutionary processes on the basis of animals living in the dark, such as the Astyanax cave fish. Biologically functionless traits show high variability, which results from neutral deleterious mutations no longer being eliminated by natural selection, which normally acts to preserve functional capability. These negative mutations accumulate until the traits they are responsible for become rudimentary or even lost. The random genetic basis of regressive evolution is in accordance with Nei’s Neutral Theory of Molecular Evolution, which applies to the molecular level. Such processes are particularly conspicuous in species living in constant darkness, where, for example in Astyanax, all traits depending on the exposure to light, like eyes, pigmentation, visually triggered aggressive behaviour, negative phototaxis, and several peripheral outcomes of circadian rhythmicity, are useless and diminish. In compensation constructive traits like taste, olfaction or the lateral line senses are improved by selection and do not show variability. Regressive and constructive traits inherit independently, proving that the rudimentation process is not driven by pleiotropic linkage between them. All these traits are subject to mosaic evolution and exhibit unproportional epistatic gene effects, which play an important role in evolutionary adaptation and improvement. Offering valuable evolutionary insights and supplemented by a wealth of illustrations, this book will appeal to evolutionary and developmental biologists alike.

Available in PDF, EPUB and Kindle. Book excerpt: After the supposed death of the Dark Queen and the capturing of the Underworld, the Sentinels believe they’ve won the war. When a strange ally of the Dark Queen named Doctor Zero emerges, he announces that he’s discovered how to turn everyone soulless. With him, he brings a fearless army, a dangerous serum, and the powerful Dark Queen by his side. To have a fighting chance against him, Riley Stark frees King Bane and the Renegades from prison. The Dark Queen’s old husband—King Lucius, who resurfaces with a bloodthirsty army of his own—disagrees with Doctor Zero’s plan to turn the world soulless and seeks revenge. When Caleb is injured in the battle, Riley is forced to trust strangers and neglect her own people to save him. As the government crumbles, new monsters come out of hiding, and dangerous groups take to the streets, Riley must protect Caleb, prevent her people from becoming soulless, and ask herself if she can continue to serve the Sentinels when they’ve hidden so much from her.

Book excerpt: A thrilling showdown brings the Dark Matter trilogy to a satsifying close. Shay is trapped at the Multiverse compound while looking for the real Callie, and an unforgiving Kai is her best chance at outsmarting Alex and saving countless lives. Shay has left Kai once again by following Alex to his Multiverse compound. Her goal is to find the real Callie, but Shay discovers that the younger girl has no memory of her past. Their hope is to leave the community. While Shay pretends to be a devoted follower, Alex makes his own plans to use Shay to spread the epidemic he caused with his dark matter experiments. The survivors will be only the most worthy humans--those who evolve special abilities. The opportunistic Freja further poisons Kai's memories of his girlfriend. Angry and hurt, Kai doubles down on his mission to reveal that his former stepfather is behind the epidemic, but he has little luck convincing the authorities--until it's almost too late to save Shay from a fate worse than death.
Download or read book Evolution in the Dark written by Naoyuki Fuse and published by Springer Science & Business Media. This book was released on 2013-09-12 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: How organisms come to possess adaptive traits is a fundamental question for evolutionary biology. Although it is almost impossible to demonstrate evolution in the laboratory, this issue can be approached by using an unusual organism, “Dark-fly”: Drosophila melanogaster kept in complete darkness for 57 years through 1,400 generations, which corresponds to 28,000 years in terms of human generations. Has Dark-fly adapted to an environment of total darkness? If so, what is the molecular nature of the adaptation? In Evolution in the Dark, the remarkable findings from the Dark-fly project performed at Kyoto University are presented. It was found that Dark-fly did not have poor eyesight, but rather exhibited higher phototaxis ability and displayed lengthened bristles on the head that function as tactile receptors. Circadian rhythms were weakened but still retained in Dark-fly. With recent progress in genome science enabling researchers to perform whole genome sequencing for Dark-fly, a large number of mutations were identified including genes encoding a light receptor, olfactory receptors, and enzymes involved in neural development. The Dark-fly project is a simple but very long-term experiment. Combined with advanced techniques in genetics and genomics, it is a valuable tool for understanding the molecular nature of adaptive evolution.
Download or read book Evolution of Darkness written by Hyginus Mathurin and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a world of technological revelations and human genius, organized religions continue to hold on to the element of faith. There are many religious questions that are satisfactorily answered in science, yet conveniently ignored by the faithful. Amidst the numerous scientific breakthroughs of the 21st Century, some still see science as the opposite of religion, even when the evidence is convincing that the two are complementary. Evolution of Darkness invites its readers to step out of the box to consider a few ideas on the dogmas that dominate religious thoughts and influences. On Christmas Eve 2012, I was invited to a candle lighting ceremony when it struck me that the Darkness we were driving out sat at the center of the flames we were holding in our hands. In other words, the Darkness in the center of the candle was responsible for the flame that provided the light in the room. This discovery enhanced my perception that the Darkness we see is the color of the energy that permeates the cosmos. Evolution of Darkness contends that this energy is intelligent and is the only authority capable of creating and sustaining this universe we live in. Every aspect of life, whether animate or inanimate, represents an expression of the Evolution of Darkness. The only legitimate expression of the God of creation is Darkness/Energy. Everything from electromagnetism to righteousness and faith are attributes of Dark Energy. From a realistic perspective, the Creator of this violent system is not a morally good God, but a God who has created a system that satisfies His needs. Everything we see around us is necessary and creates the perfect balance for the constant operation of the universe.

Book excerpt: If exercise is healthy (so good for you!), why do many people dislike or avoid it? These engaging stories and explanations will revolutionize the way you think about exercising—not to mention sitting, sleeping, sprinting, weight lifting, playing, fighting, walking, jogging, and even dancing. “Strikes a perfect balance of scholarship, wit, and enthusiasm.” —Bill Bryson, New York Times best-selling author of The Body • If we are born to walk and run, why do most of us take it easy whenever possible? • Does running ruin your knees? • Should we do weights, cardio, or high-intensity training? • Is sitting really the new smoking? • Can you lose weight by walking? • And how do we make sense of the conflicting, anxiety-inducing information about rest, physical activity, and exercise with which we are bombarded? In this myth-busting book, Daniel Lieberman, professor of human evolutionary biology at Harvard University and a pioneering researcher on the evolution of human physical activity, tells the story of how we never evolved to exercise—to do voluntary physical activity for the sake of health. Using his own research and experiences throughout the world, Lieberman recounts without jargon how and why humans evolved to walk, run, dig, and do other necessary and rewarding physical activities while avoiding needless exertion. Exercised is entertaining and enlightening but also constructive. As our increasingly sedentary lifestyles have contributed to skyrocketing rates of obesity and diseases such as diabetes, Lieberman audaciously argues that to become more active we need to do more than medicalize and commodify exercise. Drawing on insights from evolutionary biology and anthropology, Lieberman suggests how we can make exercise more enjoyable, rather than shaming and blaming people for avoiding it. He also tackles the question of whether you can exercise too much, even as he explains why exercise can reduce our vulnerability to the diseases mostly likely to make us sick and kill us.

Book excerpt: It's a target-rich environment... For both sides of this war. It's been a year and a half since they fled Los Angeles, desperate to escape the unleashed infection. An abandoned base in the isolated tundras of Alaska provides a safe harbor for the survivors. Now, turned infected are organizing. Worse, they've been given horrifying special abilities. As civilization continues to erode around Taylor and her companions, their only hope is to reach The Vault, where the last known transmission from the outside world originated. It's a risk to leave but Taylor's visions are telling them to go. They also hint that one of her companions holds a secret that could release the world from the horrors of the infection if-Taylor can manage to keep her safe. When betrayal sells them into the hands of their enemies, Taylor must use her evolving powers to protect their only hope of salvation or join the dark evolution. For those who enjoy, AG Riddle's Atlantis Gene, Justin Cronin's The Passage, or Max Brook's World War Z this one was written for you.

Book excerpt: The second book in the spine-tingling Dark Matter trilogy. Finding the cause of a deadly epidemic and a cure has never been more urgent--or uncertain. Shay, one of the rare survivors of the epidemic sweeping the UK, has surrendered herself to the Army because she believes she's a carrier of the deadly disease. Along with other survivors, she unwillingly becomes a test subject in an effort to find a cure. When the lab where she's being held is attacked, Shay and a few others escape--with the help of Dr. Alex Cross, Kai's hated stepfather and Callie's father. Alex is the leader of the cult-like group Multiverse. Their agenda is murky, but genetic engineering might be one of their goals. Meanwhile, a heartbroken Kai is determined to find Shay. He's discovered survivors aren't carriers, and Shay sacrificed herself for nothing. Teaming up with other survivors who are being hunted, Kai races to rescue Shay before it's too late. His sister, Callie, the true carrier of the epidemic, continues to hide her secret, and a wave of infection follows in her wake as she travels across the country. As mysteries deepen, the teens must decide whom to trust, and their friendships are tested. Is Callie who she says she is? Should Shay trust the man her mother ran away from--a man Kai hates? Will Kai ever forgive Shay for her betrayal?
Download or read book Why Evolution is True written by Jerry A. Coyne and published by OUP Oxford. This book was released on 2010-01-14 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: For all the discussion in the media about creationism and 'Intelligent Design', virtually nothing has been said about the evidence in question - the evidence for evolution by natural selection. Yet, as this succinct and important book shows, that evidence is vast, varied, and magnificent, and drawn from many disparate fields of science. The very latest research is uncovering a stream of evidence revealing evolution in action - from the actual observation of a species splitting into two, to new fossil discoveries, to the deciphering of the evidence stored in our genome. Why Evolution is True weaves together the many threads of modern work in genetics, palaeontology, geology, molecular biology, anatomy, and development to demonstrate the 'indelible stamp' of the processes first proposed by Darwin. It is a crisp, lucid, and accessible statement that will leave no one with an open mind in any doubt about the truth of evolution.

Download or read book Dispelling The Darkness Voyage In The Malay Archipelago And The Discovery Of Evolution By Wallace And Darwin written by John Van Wyhe and published by World Scientific. This book was released on 2013-05-10 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: “The facts of variability, of the struggle for existence, of adaptation to conditions, were notorious enough; but none of us had suspected that the road to the heart of the species problem lay through them, until Darwin and Wallace dispelled the darkness.”T H Huxley (1887)Darwin is one of the most famous scientists in history. But he was not alone. Comparatively forgotten, Wallace independently discovered evolution by natural selection in Southeast Asia. This book is based on the most thorough research ever conducted on Wallace's voyage. Closely connected, but worlds apart, Darwin and Wallace's stories hold many surprises. Did Darwin really keep his theory a secret for twenty years? Did he plagiarise Wallace? Were their theories really the same? How did Wallace hit on the solution, and on which island? This book reveals for the first time the true story of Darwin, Wallace and the discovery that would change our understanding of life on Earth forever.
Download or read book The Descent of Man and Selection in Relation to Sex written by Charles Darwin and published by Princeton University Press. This book was released on 2008-09-02 with total page 960 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the current resurgence of interest in the biological basis of animal behavior and social organization, the ideas and questions pursued by Charles Darwin remain fresh and insightful. This is especially true of The Descent of Man and Selection in Relation to Sex, Darwin's second most important work. This edition is a facsimile reprint of the first printing of the first edition (1871), not previously available in paperback. The work is divided into two parts. Part One marshals behavioral and morphological evidence to argue that humans evolved from other animals. Darwin shoes that human mental and emotional capacities, far from making human beings unique, are evidence of an animal origin and evolutionary development. Part Two is an extended discussion of the differences between the sexes of many species and how they arose as a result of selection. Here Darwin lays the foundation for much contemporary research by arguing that many characteristics of animals have evolved not in response to the selective pressures exerted by their physical and biological environment, but rather to confer an advantage in sexual competition. These two themes are drawn together in two final chapters on the role of sexual selection in humans. In their Introduction, Professors Bonner and May discuss the place of The Descent in its own time and relation to current work in biology and other disciplines.

Book excerpt: “An unforgettable journey through this twisted miracle of evolution we call ‘our body.’” —Spike Carlsen, author of A Walk Around the Block From blurry vision to crooked teeth, ACLs that tear at alarming rates and spines that seem to spend a lifetime falling apart, it’s a curious thing that human beings have beaten the odds as a species. After all, we’re the only survivors on our branch of the tree of life. The flaws in our makeup raise more than a few questions, and this detailed foray into the many twists and turns of our ancestral past includes no shortage of curiosity and humor to find the answers. Why is it that human mothers have such a life-endangering experience giving birth? Why are there entire medical specialties for teeth and feet? And why is it that human babies can’t even hold their heads up, but horses are trotting around minutes after they’re born? In this funny, wide-ranging and often surprising book, biologist Alex Bezzerides tells us just where we inherited our adaptable, achy, brilliant bodies in the process of evolution.
Download or read book Evolution written by Stephen Baxter and published by Del Rey. This book was released on 2003-01-01 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Magisterial and uplifting . . . A brilliant, grandscale sampling of sixty-five million years of human evolution . . . It shows the sweep and grandeur of life in its unrelenting course.” —The Denver Post Stretching from the distant past into the remote future, from primordial Earth to the stars, Evolution is a soaring symphony of struggle, extinction, and survival; a dazzling epic that combines a dozen scientific disciplines and a cast of unforgettable characters to convey the grand drama of evolution in all its awesome majesty and rigorous beauty. Sixty-five million years ago, when dinosaurs ruled the Earth, there lived a small mammal, a proto-primate of the species Purgatorius. From this humble beginning, Baxter traces the human lineage forward through time. The adventure that unfolds is a gripping odyssey governed by chance and competition, a perilous journey to an uncertain destination along a route beset by sudden and catastrophic upheavals. It is a route that ends, for most species, in stagnation or extinction. Why should humanity escape this fate? Praise for Evolution “Spectacular.”—The New York Times Book Review “Strong imagination, a capacity for awe, and the ability to think rigorously about vast and final things abound in the work of Stephen Baxter. . . . [Evolution] leaves the reader with a haunting portrayal of the distant future.”—Times Literary Supplement “A breath of fresh air . . . The miracle of Evolution is that it makes the triumph of life, which is its story, sound like the real story.”—The Washington Post Book World
Download or read book WTF Evolution written by Mara Grunbaum and published by Workman Publishing Company. This book was released on 2014-10-07 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: We all have our off days. Why should Evolution be any different? Maybe Evolution got carried away with an idea that was just a little too crazy—like having the Regal Horned Lizard defend itself by shooting three-foot streams of blood from its eyes. Or maybe Evolution ran out of steam (Memo to Evolution: The Irrawaddy Dolphin looks like a prototype that should have been left on the drawing board). Or maybe Evolution was feeling cheeky—a fish with hands? Joke’s on you, Red Handfish! Or maybe Evolution simply goofed up: How else to explain the overgrown teeth of the babirusas that curl backward over their face? Oops. Mara Grunbaum is a very smart, very funny science writer who celebrates the best—or, really, the worst—of Evolution’s blunders. Here are more than 100 outlandish mammals, reptiles, insects, fish, birds, and other creatures whose very existence leaves us shaking our heads and muttering WTF?! Ms. Grunbaum’s especially brilliant stroke is to personify Evolution as a well-meaning but somewhat oblivious experimenter whose conversations with a skeptical narrator are hilarious. For almost 4 billion years, Evolution has produced a nonstop parade of inflatable noses, bizarre genitalia, and seriously awkward necks. What a comedian!
