| tusklessness problem or solution: Biotic Homogenization Julie L. Lockwood, Michael L. McKinney, 2001-05-31 Biological homogenization is the dominant process shaping the future global biosphere. As global transportation becomes faster and more frequent, it is inevitable that biotic intermixing will increase. Unique local biotas will become extinct only to be replaced by already widespread biotas that can tolerate human activities. This process is affecting all aspects of our world: language, economies, and ecosystems alike. The ultimate outcome is the loss of uniqueness and the growth of uniformity. In this way, fast food restaurants exist in Moscow and Java Sparrows breed on Hawaii. Biological homogenization qualifies as a global environmental catastrophe. The Earth has never witnessed such a broad and complete reorganization of species distributions. |
| tusklessness problem or solution: The Beak of the Finch Jonathan Weiner, 2014-05-14 PULITZER PRIZE WINNER • A dramatic story of groundbreaking scientific research of Darwin's discovery of evolution that spark[s] not just the intellect, but the imagination (Washington Post Book World). “Admirable and much-needed.... Weiner’s triumph is to reveal how evolution and science work, and to let them speak clearly for themselves.”—The New York Times Book Review On a desert island in the heart of the Galapagos archipelago, where Darwin received his first inklings of the theory of evolution, two scientists, Peter and Rosemary Grant, have spent twenty years proving that Darwin did not know the strength of his own theory. For among the finches of Daphne Major, natural selection is neither rare nor slow: it is taking place by the hour, and we can watch. In this remarkable story, Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself. The Beak of the Finch is an elegantly written and compelling masterpiece of theory and explication in the tradition of Stephen Jay Gould. |
| tusklessness problem or solution: World Wildlife Crime Report 2020 United Nations Publications, 2021-03-31 The report presents the latest assessment of global trends in wildlife crime. It includes discussions on illicit rosewood, ivory, rhino horn, pangolin scales, live reptiles, tigers and other big cats, and European eel. The COVID-19 (coronavirus) pandemic has highlighted that wildlife crime is a threat not only to the environment and biodiversity, but also to human health, economic development and security. Zoonotic diseases - those caused by pathogens that spread from animals to humans - represent up to 75% of all emerging infectious diseases. Trafficked wild species and the resulting products offered for human consumption, by definition, escape any hygiene or sanitary control, and therefore pose even greater risks of infection. |

| tusklessness problem or solution: Earth System Law: Standing on the Precipice of the Anthropocene Timothy Cadman, Margot Hurlbert, Andrea C. Simonelli, 2021-12-13 This book systematically explores the emerging legal discipline of Earth System Law (ESL), challenging the closed system of law and marking a new era in law and society scholarship. Law has historically provided stability, certainty, and predictability in the ordering of social relations (predominantly between humans). However, in recent decades the Earth’s relationship in law has changed with increasing recognition of the standing of Mother Earth, inherent rights of the environment (such as flora and fauna, rivers), and now recognition of the multiple relations of the Anthropocene. This book questions the fundamental assumption that ‘the law’ only applies to humans, and that the earth, as a system, has intrinsic rights and responsibilities. In the last ten years the planet has experienced its hottest period since human evolution, and by the year 2100, unless substantive action is taken, many species will be lost, and planetary conditions will be intolerable for human civilisation as it currently exists. Relationships between humans, the biosphere, and all planetary systems must change. The authors address these challenging topics, setting the groundwork of ESL to ensure sustainable development of the coupled socio-ecological system that the Earth has become. Earth System Law is an interdisciplinary and transdisciplinary research project, and, as such, this book will be of great interest to researchers and stakeholders from a wide range of disciplines, including political science, anthropology, economics, law, ethics, sociology, and psychology. |

It combines empirical findings with theoretical arguments in order to review evidence on the prevalence rates of same-sex attraction and determine its genetic and environmental basis. Among the topics addressed: Attitudes towards same-sex attraction across human history Assessing the weak selection pressures hypothesis of attraction Assessing the male choice hypothesis of attraction Evolution of same-sex attraction in men versus women The Evolution of Same-Sex Attraction will be of interest to academics and students of evolutionary and psychological sciences, filling a gap in literature on the origins of specifically same-sex attraction. |
| tusklessness problem or solution: Of Moths and Men Judith Hooper, 2002 In this revelatory work, Judith Hooper uncovers the intellectual rivalries, petty jealousies, and flawed science behind one of the most famous experiments in evolutionary biology. Bernard Kettlewell's 1953 experiment on the peppered moths of England made him a media star on the order of Jonas Salk -- but also an unlikely tragic hero. As Hooper recounts in this rollicking scientific detective story, the truth can be subverted when the stakes are very high. Book jacket. |
| tusklessness problem or solution: Tiger Bone & Rhino Horn Richard Ellis, 2013-02-22 In parts of Korea and China, moon bears, black but for the crescent-shaped patch of white on their chests, are captured in the wild and brought to bear farms where they are imprisoned in squeeze cages, and a steel catheter is inserted into their gall bladders. The dripping bile is collected as a cure for ailments ranging from an upset stomach to skin burns. The bear may live as long as fifteen years in this state. Rhinos are being illegally poached for their horns, as are tigers for their bones, thought to improve virility. Booming economies and growing wealth in parts of Asia are increasing demand for these precious medicinals. Already endangered species are being sacrificed for temporary treatments for nausea and erectile dysfunction. Richard Ellis, one of the world's foremost experts in wildlife extinction, brings his alarm to the pages of Tiger Bone & Rhino Horn, in the hope that through an exposure of this drug trade, something can be done to save the animals most direly threatened. Trade in animal parts for traditional Chinese medicine is a leading cause of species endangerment in Asia, and poaching is increasing at an alarming rate. Most of traditional Chinese medicine relies on herbs and other plants, and is not a cause for concern. Ellis illuminates those aspects of traditional medicine, but as wildlife habitats are shrinking for the hunted large species, the situation is becoming ever more critical. One hundred years ago, there were probably 100,000 tigers in India, South China, Sumatra, Bali, Java, and the Russian Far East. The South Chinese, Caspian, Balinese, and Javan species are extinct. There are now fewer than 5,000 tigers in all of India, and the numbers are dropping fast. There are five species of rhinoceros--three in Asia and two in Africa--and all have been hunted to near extinction so their horns can be ground into powder, not for aphrodisiacs, as commonly thought, but for ailments ranging from arthritis to depression. In 1930, there were 80,000 black rhinos in Africa. Now there are fewer than 2,500. Tigers, bears, and rhinos are not the only animals pursued for the sake of alleviating human ills--the list includes musk deer, sharks, saiga antelope, seahorses, porcupines, monkeys, beavers, and sea lions--but the dwindling numbers of those rare species call us to attention. Ellis tells us what has been done successfully, and contemplates what can and must be done to save these animals or, sadly, our children will witness the extinction of tigers, rhinos, and moon bears in their lifetime. |

| tusklessness problem or solution: Elephants on the Edge G. A. Bradshaw, 2009-10-06 “At times sad and at times heartwarming . . . Helps us to understand not only elephants, but all animals, including ourselves” (Peter Singer, author of Animal Liberation). Drawing on accounts from India to Africa and California to Tennessee, and on research in neuroscience, psychology, and animal behavior, G. A. Bradshaw explores the minds, emotions, and lives of elephants. Wars, starvation, mass culls, poaching, and habitat loss have reduced elephant numbers from more than ten million to a few hundred thousand, leaving orphans bereft of the elders who would normally mentor them. As a consequence, traumatized elephants have become aggressive against people, other animals, and even one another; their behavior is comparable to that of humans who have experienced genocide, other types of violence, and social collapse. By exploring the elephant mind and experience in the wild and in captivity, Bradshaw bears witness to the breakdown of ancient elephant cultures. But, she reminds us, all is not lost. People are working to save elephants by rescuing orphaned infants and rehabilitating adult zoo and circus elephants, using the same principles psychologists apply in treating humans who have survived trauma. Bradshaw urges us to support these and other models of elephant recovery and to solve pressing social and environmental crises affecting all animals—humans included. “This book opens the door into the soul of the elephant. It will really make you think about our relationship with other animals.” —Temple Grandin, author of Animals in Translation |

| tusklessness problem or solution: Evolutionary History Edmund Russell, 2011-04-11 We tend to see history and evolution springing from separate roots, one grounded in the human world and the other in the natural world. Human beings have, however, become probably the most powerful species shaping evolution today, and human-caused evolution in other species has probably been the most important force shaping human history. This book introduces readers to evolutionary history, a new field that unites history and biology to create a fuller understanding of the past than either can produce on its own. Evolutionary history can stimulate surprising new hypotheses for any field of history and evolutionary biology. How many art historians would have guessed that sculpture encouraged the evolution of tuskless elephants? How many biologists would have predicted that human poverty would accelerate animal evolution? How many military historians would have suspected that plant evolution would convert a counter-insurgency strategy into a rebel subsidy? With examples from around the globe, this book will help readers see the broadest patterns of history and the details of their own life in a new light. |

| tusklessness problem or solution: Conservation Genetics in Mammals Jorge Ortega, Jesus E. Maldonado, 2020-01-24 This book focuses on the use of molecular tools to study small populations of rare and endangered mammals, and presents case studies that apply an evolutionary framework to address innovative questions in the emerging field of mammalian conservation genomics using a highly diverse set of novel molecular tools. Novel and more precise molecular technologies now allow experts in the field of mammology to interpret data in a more contextual and empirical fashion and to better describe the evolutionary and ecological processes that are responsible for the patterns they observe. The book also demonstrates how recent advances in genetic/genomic technologies have been applied to assess the impact of environmental/anthropogenic changes on the health of small populations of mammals. It examines a range of issues in the field of mammalian conservation genomics, such as the role that the genetic diversity of the immune system plays in disease protection and local adaptation; the use of noninvasive techniques and genomic banks as a resource for monitoring and restoring populations; the structuring of population by physical barriers; and genetic diversity. Further, by integrating research from a variety of areas – including population genetics, molecular ecology, systematics, and evolutionary and conservation biology – it enables readers to gain a deeper understanding of the conservation biology of mammals that are at increasing risk of extinction at local, regional and global scales. As such, it offers a unique resource for a broad readership interested in the conservation biology of mammals and conservation management strategies to better preserve biodiversity. |
| tusklessness problem or solution: Mammal Teeth Peter S. Ungar, 2010-10-01 Winner, 2010 PROSE Award for Excellence in the Biological Sciences. Professional and Scholarly Publishing division of the Association of American Publishers In this unique book, Peter S. Ungar tells the story of mammalian teeth from their origin through their evolution to their current diversity. Mammal Teeth traces the evolutionary history of teeth, beginning with the very first mineralized vertebrate structures half a billion years ago. Ungar describes how the simple conical tooth of early vertebrates became the molars, incisors, and other forms we see in mammals today. Evolutionary adaptations changed pointy teeth into flatter ones, with specialized shapes designed to complement the corresponding jaw. Ungar explains tooth structure and function in the context of nutritional needs. The myriad tooth shapes produced by evolution offer different solutions to the fundamental problem of how to squeeze as many nutrients as possible out of foods. The book also highlights Ungar's own path-breaking studies that show how microwear analysis can help us understand ancient diets. The final part of the book provides an in-depth examination of mammalian teeth today, surveying all orders in the class, family by family. Ungar describes some of the more bizarre teeth, such as tusks, and the mammal diversity that accompanies these morphological wonders. Mammal Teeth captures the evolution of mammals, including humans, through the prism of dental change. Synthesizing decades of research, Ungar reveals the interconnections among mammal diet, dentition, and evolution. His book is a must-read for paleontologists, mammalogists, and anthropologists. |
| tusklessness problem or solution: Ethiopia Mary Anne Fitzgerald , Philip Marsden, 2017-11-20 A lavishly illustrated photographic journey through the history and traditions of the ancient churches of Ethiopia. The ancient Aksumite Kingdom, now a part of Ethiopia, was among the first in the world to adopt Christianity as the official state religion. In AD 340 King Ezana commissioned the construction of the imposing basilica of St. Mary of Tsion. It was here, the Ethiopians say, that Menelik, son of King Solomon and the Queen of Sheba, brought the Ark of the Covenant containing the Ten Commandments. By the fifth century, nine saints from Byzantium were spreading the faith deep into the mountainous countryside, and over the next ten centuries a series of spectacular churches were either built or excavated out of solid rock, all of them in regular use to this day. Lalibela, a UNESCO World Heritage Site, has the best known cluster, but the northern region of Tigray, less well known and more remote, has many churches that are architectural masterpieces of the basilical type. Ethiopia: The Living Churches of an Ancient Kingdom traces the broad sweep of ecclesiastic history, legend, art, and faith in this sub-Saharan African kingdom as seen through the prism of sixty-six breathtaking churches, unveiling the secrets of their medieval murals, their colorful history, and the rich panoply of their religious festivals, all illustrated with more than eight hundred superb color photographs by some of the most celebrated international photographers of traditional cultures. This magnificent, large-format, full-color volume is the most comprehensive celebration yet published of Ethiopia’s extraordinary Christian heritage. Ethiopia is the third book on iconic places of worship published by Ludwig Publishing and the American University in Cairo Press, following the bestselling success of The Churches of Egypt and The History and Religious Heritage of Old Cairo. |
| tusklessness problem or solution: Quick Answers to Social Issues Bryan Osborne, 2020-03-03 The collapse of the Christian worldview in America and the West is happening, to the utter shock of Christians. Why? They’ve been blind to the enemy’s stealth attack on biblical history and authority, which has led multiple generations to abandon God’s Word as their foundation. When our culture asks the questions dealt with in this book — and our kids parrot these questions and ideas heard from schools, libraries, movies, books, music, YouTube, social media, etc. — it must be remembered they’re not innocent, unintentional questions. They stem fundamentally from a rejection of biblical authority. Quick Answers to Social Issues provides answers for some of the toughest questions of the day regarding: Marriage and sexuality from God’s Word Response to the LGBTQ+ community Animal rights and the green movement The biblical response to racism It’s imperative that Christians be ready to give answers to today’s questions! Thus, the passion and purpose of this book is to equip you with clear, concise biblical answers to effectively stand on God’s Word and boldly proclaim the gospel of Jesus Christ on the frontlines of today’s battle! |

| tusklessness problem or solution: CRISPR People Henry T. Greely, 2022-03-01 What does the birth of babies whose embryos had gone through genome editing mean--for science and for all of us? In November 2018, the world was shocked to learn that two babies had been born in China with DNA edited while they were embryos—as dramatic a development in genetics as the 1996 cloning of Dolly the sheep. In this book, Hank Greely, a leading authority on law and genetics, tells the fascinating story of this human experiment and its consequences. Greely explains what Chinese scientist He Jiankui did, how he did it, and how the public and other scientists learned about and reacted to this unprecedented genetic intervention. The two babies, nonidentical twin girls, were the first “CRISPR'd” people ever born (CRISPR, Clustered Regularly Interspaced Short Palindromic Repeats, is a powerful gene-editing method). Greely not only describes He's experiment and its public rollout (aided by a public relations adviser) but also considers, in a balanced and thoughtful way, the lessons to be drawn both from these CRISPR'd babies and, more broadly, from this kind of human DNA editing—“germline editing” that can be passed on from one generation to the next. Greely doesn't mince words, describing He's experiment as grossly reckless, irresponsible, immoral, and illegal. Although he sees no inherent or unmanageable barriers to human germline editing, he also sees very few good uses for it—other, less risky, technologies can achieve the same benefits. We should consider the implications carefully before we proceed. |

| tusklessness problem or solution: The Biology and Identification of the Coccidia (Apicomplexa) of Turtles of the World Donald W. Duszynski, Johnica J. Morrow, 2014-08-04 The Biology and Identification of the Coccidia (Apicomplexa) of Turtles of the World is an invaluable resource for researchers in protozoology, coccidia, and parasitology, veterinary sciences, animal sciences, zoology, and biology. This first-of-its-kind work offers a taxonomic guide to apicomplexan parasites of turtles that enables easy parasite identification, with a summary of virtually everything known about the biology of each known parasite species. It is an important documentation of this specific area, useful to a broad base of readers, including researchers in biology, parasitology, animal husbandry, diseases of wild and domestic animals, veterinary medicine, and faculty members in universities with graduate programs in these areas. There are about 330 turtle species on Earth; many are endangered, a growing number of species are kept as pets, and some are still used as food by humans. Turtles, like other vertebrate animals have many different kinds of parasites (viruses, bacteria, protozoa, worms, arthropods, and others). Coccidiosis in turtles has prevented large-scale turtle breeding, and represents a serious problem in need of control. This succinct and highly focused book will aid in that effort. - Offers line drawings and photomicrographs of each parasite from each hosts species - Provides methods of identification and treatment - Presents a complete historical rendition of all known publications on coccidia (and their closest relatives) from all turtle species on Earth, and evaluates the scientific and scholarly merit of each - Provides a complete species analysis of the known biology of every coccidian described from turtles - Reviews the most current taxonomy of turtles and their phylogenetic relationships needed to help assess host-specificity and evaluate what little cross-transmission work is available |

| tusklessness problem or solution: Harvesting the Biosphere Vaclav Smil, 2012-12-21 An interdisciplinary and quantitative account of human claims on the biosphere's stores of living matter, from prehistoric hunting to modern energy production. The biosphere—the Earth's thin layer of life—dates from nearly four billion years ago, when the first simple organisms appeared. Many species have exerted enormous influence on the biosphere's character and productivity, but none has transformed the Earth in so many ways and on such a scale as Homo sapiens. In Harvesting the Biosphere, Vaclav Smil offers an interdisciplinary and quantitative account of human claims on the biosphere's stores of living matter, from prehistory to the present day. Smil examines all harvests—from prehistoric man's hunting of megafauna to modern crop production—and all uses of harvested biomass, including energy, food, and raw materials. Without harvesting of the biomass, Smil points out, there would be no story of human evolution and advancing civilization; but at the same time, the increasing extent and intensity of present-day biomass harvests are changing the very foundations of civilization's well-being. In his detailed and comprehensive account, Smil presents the best possible quantifications of past and current global losses in order to assess the evolution and extent of biomass harvests. Drawing on the latest work in disciplines ranging from anthropology to environmental science, Smil offers a valuable long-term, planet-wide perspective on human-caused environmental change. |
