Book Description
The origin of the human mind remains one of the greatest mysteries of all times. The last 150 years since Charles Darwin proposed that species evolve under the influence of natural selection have been marked by great discoveries. However, the discussion of the evolution of the human intellect and specific forces that shaped the underlying brain evolution is as vigorous today as it was in Darwin's times. Using his background in neuroscience, the author offers an elegant, parsimonious theory of the evolution of the human mind and suggests experiments that could be done to test, refute, or validate the hypothesis. The basis of the theory is a simple, yet fundamental question: what happens neurologically when two objects, never before seen together (say, an apple on top of a whale), are imagined together for the first time. The scientific consensus is that a familiar object, such as an apple or a whale, is represented in the brain by thousands of neurons dispersed throughout the posterior cortex. When one sees or recalls such an object, the neurons of that object’s neuronal ensemble tend to activate into synchronous resonant activity. The neuronal ensemble binding mechanism, based on the Hebbian principle “neurons that fire together, wire together,” came to be known as the binding-by-synchrony hypothesis. However, while the Hebbian principle explains how we perceive a familiar object, it does not explain the infinite number of novel objects that humans can voluntarily imagine. The neuronal ensembles encoding those objects cannot jump into spontaneous synchronized activity on their own since the parts forming those novel images have never been seen together. The author argues that to account for imagination, the binding-by-synchrony hypothesis would need to be extended to include the phenomenon of mental synthesis whereby the brain actively and intentionally synchronizes independent neuronal ensembles into one morphed image. Thus, the apple neuronal ensemble is synchronized with the whale neuronal ensemble, and the two disparate objects are perceived together. The synchronization mechanism of mental synthesis is likely responsible for many imaginative and creative traits that scientists have recognized as being uniquely human, despite not having a precise neurological understanding of the process. How did humans acquire mental synthesis? As of 100,000 years ago, hominins had already evolved both a greater control of perception by the prefrontal cortex and a nearly modern speech-production apparatus. However the connections between the prefrontal cortex and the posterior cortex remained asynchronous; the prefrontal cortex was unable to synchronize independent neuronal ensembles, speech remained finite and non-syntactic: one word was only able to communicate one image. At that time, a single mutation delayed the ontogenetic development of the prefrontal cortex and permitted the newly invented syntactic speech to train the synchronous connections between the prefrontal cortex and the posterior cortex. This allowed the acquisition of mental synthesis and propelled humans to behavioral modernity. These behaviorally modern humans excelled at performing mental simulations, which resulted in the dramatic acceleration of technological progress; the human population exploded and humans quickly settled most habitable areas of the planet. Armed with the ability to mentally simulate any plan and then to communicate it to their companions, humans rapidly became the dominant species.

Book Description
An enormous amount of scientific research compels two fundamental conclusions about the human mind: The mind is the product of evolution; and the mind is shaped by culture. These two perspectives on the human mind are not incompatible, but, until recently, their compatibility has resisted rigorous scholarly inquiry. Evolutionary psychology documents many ways in which genetic adaptations govern the operations of the human mind. But evolutionary inquiries only occasionally grapple seriously with questions about human culture and cross-cultural differences. By contrast, cultural psychology documents many ways in which thought and behavior are shaped by different cultural experiences. But cultural inquires rarely consider evolutionary processes. Even after decades of intensive research, these two perspectives on human psychology have remained largely divorced from each other. But that is now changing - and that is what this book is about. Evolution, Culture, and the Human Mind is the first scholarly book to integrate evolutionary and cultural perspectives on human psychology. The contributors include world-renowned evolutionary, cultural, social, and cognitive psychologists. These chapters reveal many novel insights linking human evolution to both human cognition and human culture – including the evolutionary origins of cross-cultural differences. The result is a stimulating introduction to an emerging integrative perspective on human nature.

Book Description
The history of science abounds with momentous theories that disrupted conventional wisdom and yet were eventually proven true. Ajit Varki and Danny Brower's "Mind over Reality" theory is poised to be one such idea-a concept that runs counter to commonly-held notions about human evolution but that may hold the key to understanding why humans evolved as we did, leaving all other related species far behind. At a chance meeting in 2005, Brower, a geneticist, posed an unusual idea to Varki that he believed could explain the origins of human uniqueness among the world's species: Why is there no humanlike elephant or humanlike dolphin, despite millions of years of evolutionary opportunity? Why is it that humans alone can understand the minds of others? Haunted by their encounter, Varki tried years later to contact Brower only to discover that he had died unexpectedly. Inspired by an incomplete manuscript Brower left behind, Denial presents a radical new theory on the origins of our species. It was not, the authors argue, a biological leap that set humanity apart from other species, but a psychological one: namely, the uniquely human ability to deny reality in the face of inarguable evidence-including the willful ignorance of our own inevitable deaths. The awareness of our own mortality could have caused anxieties that resulted in our avoiding the risks of competing to procreate-an evolutionary dead-end. Humans therefore needed to evolve a mechanism for overcoming this hurdle: the denial of reality. As a consequence of this evolutionary quirk we now deny any aspects of reality that are not to our liking-we smoke cigarettes, eat unhealthy foods, and avoid exercise, knowing these habits are a prescription for an early death. And so what has worked to establish our species could be our undoing if we continue to deny the consequences of unrealistic approaches to everything from personal health to financial risk-taking to climate change. On the other hand reality-denial affords us many valuable attributes, such as optimism, confidence, and courage in the face of long odds. Presented in homage to Brower's original thinking, Denial offers a powerful warning about the dangers inherent in our remarkable ability to ignore reality-a gift that will either lead to our downfall, or continue to be our greatest asset.

Book Description
National Book Award Finalist: “This man’s ideas may be the most influential, not to say controversial, of the second half of the twentieth century.”—Columbus Dispatch At the heart of this classic, seminal book is Julian Jaynes's still-controversial thesis that human consciousness did not begin far back in animal evolution but instead is a learned process that came about only three thousand years ago and is still developing. The implications of this revolutionary scientific paradigm extend into virtually every aspect of our psychology, our history and culture, our religion—and indeed our future. “Don’t be put off by the academic title of Julian Jaynes’s The Origin of Consciousness in the Breakdown of the Bicameral Mind. Its prose is always lucid and often lyrical…he unfolds his case with the utmost intellectual rigor.”—The New York Times “When Julian Jaynes . . . speculates that until late in the twentieth millennium BC men had no consciousness but were automatically obeying the voices of the gods, we are astounded but compelled to follow this remarkable thesis.”—John Updike, The New Yorker “He is as startling as Freud was in The Interpretation of Dreams, and Jaynes is equally as adept at forcing a new view of known human behavior.”—American Journal of Psychiatry

Book Description
A closer look at genealogy, incorporating how biological, anthropological, and technical factors can influence human lives We are at a pivotal moment in understanding our remote ancestry and its implications for how we live today. The barriers to what we can know about our distant relatives have been falling as a result of scientific advance, such as decoding the genomes of humans and Neanderthals, and bringing together different perspectives to answer common questions. These collaborations have brought new knowledge and suggested fresh concepts to examine. The results have shaken the old certainties. The results are profound; not just for the study of the past but for appreciating why we conduct our social lives in ways, and at scales, that are familiar to all of us. But such basic familiarity raises a dilemma. When surrounded by the myriad technical and cultural innovations that support our global, urbanized lifestyles we can lose sight of the small social worlds we actually inhabit and that can be traced deep into our ancestry. So why do we need art, religion, music, kinship, myths, and all the other facets of our over-active imaginations if the reality of our effective social worlds is set by a limit of some one hundred and fifty partners (Dunbar’s number) made of family, friends, and useful acquaintances? How could such a social community lead to a city the size of London or a country as large as China? Do we really carry our hominin past into our human present? It is these small worlds, and the link they allow to the study of the past that forms the central point in this book.

Book Description
It is the most complex and mysterious object in the universe. Covered by a dull grey membrane, it resembles a gigantic, convoluted fungus. Its inscrutability has captivated scientists, philosophers and artists for centuries. It is, of course, the human brain. With the help of science we can now begin to understand the extraordinary complexity of the brain's circuits: we can see which nerve cells generate electricity as we fall in love, tell a lie or dream of a lottery win. And inside the 100 billion cells of this rubbery network is something remarkable: you. In this entertaining and accessible book, Robert Winston takes us deep into the workings of the human mind and shows how our emotions and personality are the result of genes and environment. He explains how memories are formed and lost, how the ever-changing brain is responsible for toddler tantrums and teenage angst, plus he reveals the truth behind extra-sensory perception, déjà vu and out-of-body experiences. He also tells us how to boost our intelligence, how to tap into creative powers we never knew we had, how to break old habits and keep our brain fit and active as we enter old age. The human mind is all we have to help us to understand it. Paradoxically, it is possible that science may never quite explain everything about this extraordinary mechanism that makes each of us unique.
