Description : Read Now Evolution S Witness by Ivan R Schwab and you can download with pub, pdf, txt, doc, and more file format with free account. with predation and carnivory as catalysts, the first known eye appeared in a trilobite during the cambrian explosion approximately 543 million years ago. this period was a crucible of evolution and teemed with anatomic creativity although the journey to formed vision actually began billions of years before that. the cambrian period, however, spawned nearly all morphologic forms of the eye, followed by descent over hundreds of millions of years providing an unimaginable variety of eyes with at least ten different designs. some eyes display spectacular creativity with mirror, scanning or telephoto optics. some of these ocular designs are merely curiosities, while others offer the finest visual potential packed into a small space, limited only by the laws of diffraction or physiological optics. for example, some spiders developed tiny, well-formed eyes with scanning optics and three visual pigments; scallops have 40-100 eyes circling their mantle, each of which has mirror optics and contains two separate retinae per eye; deep ocean fish have eyes shaped like tubes containing yellow lenses to break camouflage; and some birds have vision five times better than ours; but this is only part of the story. each animal alive today has an eye that fits is niche perfectly demonstrating the intimacy of the evolutionary process as no other organ could. the evolution of the eye is one of the best examples of darwinian principles. although few eyes fossilize in any significant manner, many details of this evolution are known and understood. from initial photoreception 3.75 billion years ago to early spatial recognition in the first cupped eyespot in euglena to fully formed camera style eyes the size of beach balls in ichthyosaurs, animals have processed light to compete and survive in their respective niches. it is evolution's greatest gift and its greatest triumph. this is the story of the evolution of the eye.

Byram Karasu and you can download with pub, pdf, txt, doc, and more file format with free account. in life witness: evolution of the psychotherapist, t. byram karasu demonstrates how a young therapist can become an expert clinician by transcending his own school of therapy. every young therapist attempts to perfect his skills by anchoring onto a single paradigm and becoming an expert technician of that particular school. within the first five to ten years of practice the so-called experiential evolution phase the therapist finds that no single paradigm is suitable for treating all psychopathology. the therapist thus begins to appropriate techniques from other schools of psychotherapy, and by shifting paradigms, synchronizes himself with the patient s mind. it is from this synchronization that all his techniques begin to evolve and an expert clinician can evolve into a master psychotherapist. the therapist who has transcended his school of psychotherapy now must transcend the field of psychotherapy itself. if he wants to address the patient s existential issues as well, the therapist first has to come to terms with those issues himself. after all, the therapist can take the patient only so far as he himself has come. life witness demonstrates that this formative evolution phase of a therapist encompasses a broad education in literature, philosophy, and spirituality. karasu ultimately concludes that therapists must find the meaning and purpose of life before they can cultivate an authentic self and become someone whose presence is itself therapeutic. once this occurs, all "therapeutic messages" will naturally emanate from within."

Description : Read Now Darwin S Devices by John Long and you can download with pub, pdf, txt, doc, and more file format with free account. what happens when we let robots play the game of life? the challenge of studying evolution is that the history of life is buried in the past—we can’t witness the dramatic events that shaped the adaptations we see today. but biorobotics expert john long has found an ingenious way to overcome this problem: he creates robots that look and behave like extinct animals, subjects them to evolutionary pressures, lets them compete for mates and resources, and mutates their ‘genes’. in short, he lets robots play the game of life. in darwin’s devices, long tells the story of these evolving biorobots—how they came to be, and what they can teach us about the biology of living and extinct species. evolving biorobots can replicate creatures that disappeared from the earth long ago, showing us in real time what happens in the face of unexpected environmental challenges. biomechanically correct models of backbones functioning as part of an autonomous robot, for example, can help us understand why the first vertebrates evolved them. but the most impressive feature of these robots, as long shows, is their ability to illustrate the power of evolution to solve difficult technological challenges autonomously—without human input regarding what a workable solution might be. even a simple robot can create complex behavior, often learning or evolving greater intelligence than humans could possibly program. this remarkable idea could forever alter the face of engineering, design, and even warfare. an amazing tour through the workings of a fertile mind, darwin’s devices will make you rethink everything you thought you knew about evolution, robot intelligence, and life itself.

Description : Read Now Nothing Created Everything by Ray Comfort and you can download with pub, pdf, txt, doc, and more file format with free account. richard dawkins is arguably the modern poster boy for charles darwin. however, a key difference radically separates the two men. darwin believed in the existence of god and calls god the "creator" seven times in "the origin of species." dawkins, in contrast, claims, "the more you understand the significance of evolution, the more you are pushed...towards atheism." it seems professor dawkins thinks charles darwin didn't understand his own theory. just months after the 2009 discovery of the supposed "missing link," author ray comfort turns the tables on evolutionists. in "nothing created everything," he examins the evidence for evolution and shows it is lacking. he demonstrates that when it comes to explaining how life began, atheists and evolutionists offer faith not facts. ironically, atheists insist nothing created everything, a scientific impossibility. in a conversational tone, comfort speaks to both atheists and believers and urges this discussion be based on hard evidence. and when it is, he insists, people will realize evolution is a theory that can't be tested or measured and therefore can't be scientific.

Description : Read Now The Human Instinct by Kenneth R. Miller and you can download with pub, pdf, txt, doc, and more file format with free account. from one of america’s best-known biologists, a revolutionary new way of thinking about evolution that shows “why, in light of our origins, humans are still special” (edward j. larson, pulitzer prize–winning author of evolution). once we had a special place in the hierarchy of life on earth—a place confirmed by the literature and traditions of every human tribe. but then the theory of evolution arrived to shake the tree of human understanding to its roots. to many of the most passionate advocates for darwin’s theory, we are just one species among multitudes, no more significant than any other. even our minds are not our own, they tell us, but living machines programmed for nothing but survival and reproduction. in the human instinct, brown university biologist kenneth r. miller “confronts both lay and professional misconceptions about evolution” (publishers weekly, starred review), showing that while evolution explains how our bodies and brains were shaped, that heritage does not limit or predetermine human behavior. in fact, miller argues in this “highly recommended” (forbes) work that it is only thanks to evolution that we have the power to shape our destiny. equal parts natural science and philosophy, the human instinct makes an “absorbing, lucid, and engaging…case that it was evolution that gave us our humanity” (ursula goodenough, professor of biology at washington university in st. louis).

Description : Read Now Evolving Ourselves by Juan Enriquez and you can download with pub, pdf, txt, doc, and more file format with free account. "futurist juan enriquez and scientist steve gullans conduct a sweeping tour of how humans are changing the course of evolution for all species--sometimes intentionally, sometimes not. for example: what if life forms are limited only by the bounds of our imagination? are designer babies and pets, de-extinction, even entirely newspecies fair game?; as humans, animals, and plants become ever more resistant to disease and aging, what will become the leading causes of death?; man-machine interfaces may allow humans to live much longer. what will happen when we transfer parts of our 'selves' into clones, into stored cells and machines? though these harbingers of change are deeply unsettling, the authors argue we are also in an epoch of tremendous opportunity. future humans, perhaps a more diverse, resilient, gentler, and intelligent species, may become better caretakers of the planet--but only if we make the right choices now."--provided by publisher.
