After having read this book you will never see birds in the same way again. The unexpected patterns displayed by a bird’s body have been seen as bizarre events that demanded little attention or were described as ‘amazing curiosities’. None of these surprising features seem to be fortuitous. They appear to be an integral part of a rigid order and a coherent geometry, which is directed by simple gene interactions and molecular cascades occurring at various cellular levels, and at different times, during the organism’s development. A novel geometry unfolds in front of your eyes, giving the body configurations another meaning. Lima-de-Faria is Professor Emeritus of Molecular Cytogenetics at Lund University, Lund, Sweden. This is his sixth book dealing with the molecular organization of the chromosome and its implications for the understanding of the mechanisms responsible for biological evolution.

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.

Introducing a new holistic paradigm that provides a clear new pair of lens - for the mind. This new concept depolarizes our perceptions on reality by reconciling the ancient and deeply compelling paradox known as dualism. As it unravels the greatest mystery of our existential lives, that great enigma that in spirituality led us from “all good”, to good & evil; and in science, leads to two laws that we cannot reconcile. However, with this new pair of depolarizing lens, we are able to conceive something quite remarkable, space, time and how existing things are formed in it. This book is very relevant because it is antidote to the social and political ills of our societies. The polarization inherent in our present paradigm creates social diseases such as sexism, racism, wars, and the myriad forms of hate we tend to indulge in. We daily confront the ravages of political neglect that we are forced to bear, as we try to cope with these corrupted ways of being. The benefit of this new holistic paradigm is that it provides a logical, science-based understanding that is so obvious and universal, we are essentially oblivious to it; and, it resolves the greatest paradoxes we face as spiritual beings in a materialistic world. This book promotes well-being for the soul in the evolution of the mind. • Reveals the origin of the invisible field we call Space(Time) • Explains how existing things emerge and form into being • Sheds whole new light on the meaning of GOD • Reconciles the divides between Eastern and Western traditions in religion, science, and philosophy • Bridges Dualism (Separation & Polarization) • Self Actualization Meditations (“I AM ‘Mind’, I AM ‘Consciousness’”)

The essential text for ornithology courses, this book will leave students with a lifelong understanding and appreciation of the biology and ecology of birds. Aves, the birds, is the wildlife group that people most frequently encounter. With over 10,000 species worldwide, these animals are part of our everyday experience. They are also the focus of intense research, and their management and conservation is a subject of considerable effort throughout the world. But what are the defining attributes that make a bird a bird? Aimed at undergraduate and graduate students, Ornithology provides a solid modern foundation for understanding the life and development of birds. Written by renowned experts from around the globe, this comprehensive textbook draws on the latest research to create an innovative learning experience. Moving beyond bones, muscle, and feathers, it provides the core information needed to “build” the bird, linking anatomy and physiology with ecology and behavior. As it reviews the major orders of birds, the book highlights their wide diversity and critically evaluates ornithological concepts and theories. Incorporating brief biographies of leaders in the field, the text describes their contributions in the context of key historical events in bird science. Each chapter ends with a summary of the material covered, a discussion of potential management and conservation applications, and suggested study questions that will stimulate thought and discussion.

Nearly a decade ago I began planning this book with the goal of summarizing the existing body of knowledge on ecology of freshwater fishes in a way similar to that of H. B. N. Hynes' comprehensive treatise Ecology of Running Waters for streams. The time seemed appropriate, as there had been several recent volumes that synthesized much information on a range of topics important in fish ecology, from biogeographic to local scales. For example, the "Fish Atlas" (Lee et aI. , 1980) had provided range maps and basic entry to the original literature for all freshwater fishes in North America, and in 1986 Hocutt and Wiley's Zoogeography of North American Fishes provided a detailed synthesis of virtually everything known about distributional ecology of fishes on that continent. Tim Berra (1981) had summarized in convenient map form the worldwide distribution of all freshwater fish families, and Joe Nelson's 1976 and 1984 editions of Fishes of the World had appeared. To complement these "big picture" views of fish distributions, the volume on Community and Evolutionary Ecology of North American Freshwater Fishes, edited by David Heins and myself (Matthews and Heins, 1987), had provided an opportunity for more than 30 individuals or groups to summarize their work on stream fishes (albeit mostly for warmwater systems).

A Dictionary of Birds enlists contributions from over 280 ornithologists and other specialists from around the world. Major, authoritative articles cover the field of modern ornithology and related subjects, many of them running to several thousand words. In addition there are articles on all the bird families, almost all of which are illustrated by a representative species. There are also numerous short entries defining special terms, application of names, etc. The total gives a text of over 800,000 words, supported by more than 500 photographs, drawings and diagrams. The photographs have been selected under the guidance of Eric Hosking to illustrate different activities of birds, and Robert Gillmor has assembled a collection of over 200 drawings of birds, almost all of which were specially drawn for the Dictionary. Compiled for the British Ornithologists' Union, this new work is in line of succession from Newton's A Dictionary of Birds of 1896 and Landsborough Thomson's A New Dictionary of Birds published in 1964 (2nd impression 1965) and now long out of print. This dictionary, encyclopedic in treatment, is destined to be a major reference in any ornithologist's library; and its editors and contributors, most of whom gave their time and knowledge freely, have earned the thanks and acclaim of users for many years to come.
