Download or read book Do Fish Feel Pain written by Victoria Braithwaite and published by OUP Oxford. This book was released on 2010-03-25 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: While there has been increasing interest in recent years in the welfare of farm animals, fish are frequently thought to be different. In many people's perception, fish, with their lack of facial expressions or recognisable communication, are not seen to count when it comes to welfare. Angling is a major sport, and fishing a big industry. Millions of fish are caught on barbed hooks, or left to die by suffocation on the decks of fishing boats. Here, biologist Victoria Braithwaite explores the question of fish pain and fish suffering, explaining what we now understand about fish behaviour, and examining the related ethical questions about how we should treat these animals. She asks why the question of pain in fish has not been raised earlier, indicating our prejudices and assumptions; and argues that the latest and growing scientific evidence would suggest that we should widen to fish the protection currently given to birds and mammals.
Download or read book Human Brain Evolution written by Stephen Cunnane and published by John Wiley & Sons. This book was released on 2010-06-01 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of the human brain and cognitive ability is one of the central themes of physical/biological anthropology. This book discusses the emergence of human cognition at a conceptual level, describing it as a process of long adaptive stasis interrupted by short periods of cognitive advance. These advances were not linear and directed, but were acquired indirectly as part of changing human behaviors, in other words through the process of exaptation (acquisition of a function for which it was not originally selected). Based on studies of the modem human brain, certain prerequisites were needed for the development of the early brain and associated cognitive advances. This book documents the energy and nutrient constraints of the modern brain, highlighting the significant role of long-chain polyunsaturated fatty acids (LC-PUFA) in brain development and maintenance. Crawford provides further emphasis for the role of essential fatty acids, in particular DHA, in brain development, by discussing the evolution of the eye and neural systems. This is an ideal book for Graduate students, post docs, research scientists in Physical/Biological Anthropology, Human Biology, Archaeology, Nutrition, Cognitive Science, Neurosciences. It is also an excellent selection for a grad student discussion seminar.
Download or read book Evolution of The Brain and Intelligence written by Harry Jerison and published by Elsevier. This book was released on 2012-12-02 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolution of the Brain and Intelligence covers the general principles of behavior and brain function. The book is divided into four parts encompassing 17 chapters that emphasize the implications of the history of the brain for the evolution of behavior in vertebrates. The introductory chapter covers the studies of animal behavior and their implications about the nature of the animal’s world. The following chapters emphasize methodological issues and the meanings of brain indices and brain size, as well as the general anatomy of the brain. Other chapters discuss the history of the brain in the major vertebrate groups that were known about 300 million years ago to determine the fate of these early vertebrate groups. Discussions on broad trends in evolution and their implications for the evolution of intelligence are also included. Substantive matter on the brains, bodies, and associated mechanisms of behavior of vertebrates are covered in the remaining chapters of the book, with an emphasis on evolution “above the species level . This book is of value to anthropologists, behavioral scientists, zoologists, paleontologists, and neurosciences students.
Download or read book Molecular Origins of Brain and Body Geometry written by Antonio Lima-de-Faria and published by Springer. This book was released on 2014-10-07 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: New concepts arise in science when apparently unrelated fields of knowledge are put together in a coherent way. The recent results in molecular biology allow to explain the emergence of body patterns in animals that before could not be understood by zoologists. There are no ”fancy curiosities” in nature. Every pattern is a product of a molecular cascade originating in genes and a living organism arises from the collaboration of these genes with the outer physical environment. Tropical fishes are as startling in their colors and geometric circles as peacocks. Tortoises are covered with the most regular triangles, squares and concentric circles that can be green, brown or yellow. Parallel scarlet bands are placed side by side of black ones along the body of snakes. Zebras and giraffes have patterns which are lessons in geometry, with their transversal and longitudinal stripes, their circles and other geometric figures. Monkeys, like the mandrills, have a spectacularly colored face scarlet nose with blue parallel flanges and yellow beard. All this geometry turns out to be highly molecular. The genes are many and have been DNA sequenced. Besides they not only deal with the coloration of the body but with the development of the brain and the embryonic process. A precise scenario of molecular events unravels in the vertebrates. It may seem far-fetched, but the search for the origin of this geometry made it mandatory to study the evolution of matter and the origin of the brain. It turned out that matter from its onset is pervaded by geometry and that the brain is also a prisoner of this ordered construction. Moreover, the brain is capable of altering the body geometry and the geometry of the environment changes the brain. Nothing spectacular occurred when the brain arrived in evolution. Not only it came after the eye, which had already established itself long ago, but it had a modest origin. It started from sensory cells on the skin that later aggregated into clusters of neurons that formed ganglia. It also became evident that pigment cells, that decide the establishment of the body pattern, originate from the same cell population as neurons (the neural crest cells). This is a most revealing result because it throws light on the power that the brain has to rapidly redirect the coloration of the body and to change its pattern. Recent experiments demonstrate how the brain changes the body geometry at will and within seconds, an event that could be hardly conceived earlier. Moreover, this change is not accidental it is related to the surrounding environment and is also used as a mating strategy. Chameleons know how to do it as well as flat fishes and octopuses. No one would have dared to think that the brain had its own geometry. How could the external geometry of solids or other figures of our environment be apprehended by neurons if these had no architecture of their own? Astonishing was that the so called ”simple cells”, in the neurons of the primary visual cortex, responded to a bar of light with an axis of orientation that corresponded to the axis of the cell’s receptive field. We tend to consider our brain a reliable organ. But how reliable is it? From the beginning the brain is obliged to transform reality. Brain imagery involves: form, color, motion and sleep. Unintentionally these results led to unexpected philosophical implications. Plato’s pivotal concept that ”forms” exist independently of the material world is reversed. Atoms have been considered to be imaginary for 2,000 years but at present they can be photographed, one by one, with electron microscopes. The reason why geometry has led the way in this inquiry is due to the fact that where there is geometry there is utter simplicity coupled to rigorous order that underlies the phenomenon where it is recognized. Order allows variation but imposes at the same time a canalization that is patent in what we call evolution.

Download or read book Your Inner Fish written by Neil Shubin and published by Vintage. This book was released on 2008-01-15 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paleontologist and professor of anatomy who co-discovered Tiktaalik, the “fish with hands,” tells a “compelling scientific adventure story that will change forever how you understand what it means to be human” (Oliver Sacks). By examining fossils and DNA, he shows us that our hands actually resemble fish fins, our heads are organized like long-extinct jawless fish, and major parts of our genomes look and function like those of worms and bacteria. Your Inner Fish makes us look at ourselves and our world in an illuminating new light. This is science writing at its finest—enlightening, accessible and told with irresistible enthusiasm.
Download or read book The Lives of the Brain written by John S. Allen and published by Harvard University Press. This book was released on 2010-02-15 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though we have other distinguishing characteristics (walking on two legs, for instance, and relative hairlessness), the brain and the behavior it produces are what truly set us apart from the other apes and primates. And how this three-pound organ composed of water, fat, and protein turned a mammal species into the dominant animal on earth today is the story John S. Allen seeks to tell. Adopting what he calls a “bottom-up” approach to the evolution of human behavior, Allen considers the brain as a biological organ; a collection of genes, cells, and tissues that grows, eats, and ages, and is subject to the direct effects of natural selection and the phylogenetic constraints of its ancestry. An exploration of the evolution of this critical organ based on recent work in paleoanthropology, brain anatomy and neuroimaging, molecular genetics, life history theory, and related fields, his book shows us the brain as a product of the contexts in which it evolved: phylogenetic, somatic, genetic, ecological, demographic, and ultimately, cultural-linguistic. Throughout, Allen focuses on the foundations of brain evolution rather than the evolution of behavior or cognition. This perspective demonstrates how, just as some aspects of our behavior emerge in unexpected ways from the development of certain cognitive capacities, a more nuanced understanding of behavioral evolution might develop from a clearer picture of brain evolution.

Download or read book The Central Nervous System of Cartilaginous Fishes written by W.J.A.J. Smeets and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although a large body of data about the structure of the central nervous system of cartilaginous fishes has now been accumulated, a systematic survey of the neuromorphology of this, in so many respects, highly interesting group of animals is lacking. The present book is an effort to fill this gap. The information provided is derived partly from the literature and partly from original observations based on our own material. We have attempted to present a complete review of the relevant literature of the last 25 years, but the earlier literature has also been thoroughly scrutinized. Wherever possible we have commented on the functional significance of the various structures. The information available in the literature has been incorporated with our own findings from a detailed study of four species, the sharks Squalus acanthias and Scyliorhinus canicula, the ray Raja clavata and the holocepha Ii an Hydrolagus collei. Although these species do not reflect the total range of cartilaginous fishes they do exemplify the main features of the major groups.
Download or read book Encyclopedia of the Human Brain written by and published by Elsevier. This book was released on 2002-07-04 with total page 3607 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, enormous strides have been made in understanding the human brain. The advent of sophisticated new imaging techniques (e.g. PET, MRI, MEG, etc.) and new behavioral testing procedures have revolutionized our understanding of the brain, and we now know more about the anatomy, functions, and development of this organ than ever before. However, much of this knowledge is scattered across scientific journals and books in a diverse group of specialties: psychology, neuroscience, medicine, etc. The Encyclopedia of the Human Brain places all information in a single source and contains clearly written summaries on what is known of the human brain. Covering anatomy, physiology, neuropsychology, clinical neurology, neuropharmacology, evolutionary biology, genetics, and behavioral science, this four-volume encyclopedia contains over 200 peer reviewed signed articles from experts around the world. The Encyclopedia articles range in size from 5-30 printed pages each, and contain a definition paragraph, glossary, outline, and suggested readings, in addition to the body of the article. Lavishly illustrated, the Encyclopedia includes over 1000 figures, many in full color. Managing both breadth and depth, the Encyclopedia is a must-have reference work for life science libraries and researchers investigating the human brain.
Download or read book Biology Conservation and Sustainable Development of Sturgeons written by Ramón Carmona and published by Springer Science & Business Media. This book was released on 2008-11-09 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sturgeons are considered “living fossils”, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats. This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical distribution. Other relevant species (such as Huso huso, A. oxyrhinchus, A. ruthenus, A. stellatus) and areas (Germany, Russia, North America) are also considered. The contents are organised in three sections: Taxonomy and Biogeography (including the morphological and genetic analyses that clarify the taxonomy and phylogeny of sturgeons, focused on those from Southern Europe), Biology and Aquaculture (where several aspects of the developmental biology, feeding, and reproduction are considered in relation to the improvement of sturgeon farming), and Recovery and Conservation (that collates and analyses different recovery research actions, the ecology of the rivers for restoration as well as the problems related to the trade of caviar).

Download or read book The Nervous System of Cartilaginous Fishes written by K. E. Yopak and published by S. Karger AG (Switzerland). This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cartilaginous fishes are comprised of nearly 1,200 species and occur in diverse ecological niches. Though once thought to have empirically simple brains, cartilaginous fishes possess a battery of highly developed sensory systems, a complex range of innate behaviors, and relatively enlarged and complex brains, which, unlike many other vertebrate systems, continue to grow throughout life. Their nervous system represents an early, yet remarkably complete stage in the evolution of the vertebrate brain, thereby allowing for establishment of the general rules that underlie brain evolution across vertebrates. Using a variety of approaches, ranging from traditional histological methodologies, to immunohistochemistry and electrophysiology, to more novel application of magnetic resonance imaging, this publication explores the diversity in peripheral and central development across this group, while simultaneously defining the neural commonalities that evolved at least as early as the cartilaginous fishes and have been conserved across all vertebrates. This publication will be of interest to a wide variety of evolutionary biologists, neuroanatomists, as well as fish biologists, sensory physiologists, and ecologists.
