How did the human brain with all its manifold capacities evolve from basic functions in simple organisms that lived nearly a billion years ago? John Allman addresses this question in Evolving Brains, a provocative study of brain evolution that introduces readers to some of the most exciting developments in science in recent years.

Religions and mythologies from around the world teach that God or gods created humans. Atheist, humanist, and materialist critics, meanwhile, have attempted to turn theology on its head, claiming that religion is a human invention. In this book, E. Fuller Torrey draws on cutting-edge neuroscience research to propose a startling answer to the ultimate question. Evolving Brains, Emerging Gods locates the origin of gods within the human brain, arguing that religious belief is a by-product of evolution. Based on an idea originally proposed by Charles Darwin, Torrey marshals evidence that the emergence of gods was an incidental consequence of several evolutionary factors. Using data ranging from ancient skulls and artifacts to brain imaging, primatology, and child development studies, this book traces how new cognitive abilities gave rise to new behaviors. For instance, autobiographical memory, the ability to project ourselves backward and forward in time, gave Homo sapiens a competitive advantage. However, it also led to comprehension of mortality, spurring belief in an alternative to death. Torrey details the neurobiological sequence that explains why the gods appeared when they did, connecting archaeological findings including clothing, art, farming, and urbanization to cognitive developments. This book does not dismiss belief but rather presents religious belief as an inevitable outcome of brain evolution. Providing clear and accessible explanations of evolutionary neuroscience, Evolving Brains, Emerging Gods will shed new light on the mechanics of our deepest mysteries.

"Integrates a multiplicity of evolutionary developments involving genetics, response, to climate variations, social organization, the nervous system, environment, and behavior."--Jacket.

In The Descent of Man, Charles Darwin proposed that an ant’s brain, no larger than a pin’s head, must be sophisticated to accomplish all that it does. Yet today many people still find it surprising that insects and other arthropods show behaviors that are much more complex than innate reflexes. They are products of versatile brains which, in a sense, think. Fascinating in their own right, arthropods provide fundamental insights into how brains process and organize sensory information to produce learning, strategizing, cooperation, and sociality. Nicholas Strausfeld elucidates the evolution of this knowledge, beginning with nineteenth-century debates about how similar arthropod brains were to vertebrate brains. This exchange, he shows, had a profound and far-reaching impact on attitudes toward evolution and animal origins. Many renowned scientists, including Sigmund Freud, cut their professional teeth studying arthropod nervous systems. The greatest neuroanatomist of them all, Santiago Ramón y Cajal—founder of the neuron doctrine—was awed by similarities between insect and mammalian brains. Writing in a style that will appeal to a broad readership, Strausfeld weaves anatomical observations with evidence from molecular biology, neuroethology, cladistics, and the fossil record to explore the neurobiology of the largest phylum on earth—and one that is crucial to the well-being of our planet. Highly informative and richly illustrated, Arthropod Brains offers an original synthesis drawing on many fields, and a comprehensive reference that will serve biologists for years to come.

Aimed at advanced undergraduate and graduate students, this textbook describes some of the basic principles affecting brain evolution. The author refers to data from a wide array of vertebrates while minimizing technical jargon. Particular attention has been paid to the ways in which changes in brain structure impact function and behavior. The volume concludes with a discussion on how mammal brains diverged from other brains and how Homo sapiens evolved a very large and special brain.

"Much is conserved in vertebrate evolution, but significant changes in the nervous system occurred at the origin of vertebrates and in most of the major vertebrate lineages. This book examines these innovations and relates them to evolutionary changes in other organ systems, animal behavior, and ecological conditions at the time. The resulting perspective clarifies what makes the major vertebrate lineages unique and helps explain their varying degrees of ecological success. One of the book's major conclusions is that vertebrate nervous systems are more diverse than commonly assumed, at least among neurobiologists. Examples of important innovations include not only the emergence of novel brain regions, such as the cerebellum and neocortex, but also major changes in neuronal circuitry and functional organization. A second major conclusion is that many of the apparent similarities in vertebrate nervous systems resulted from convergent evolution, rather than inheritance from a common ancestor. For example, brain size and complexity increased numerous times, in many vertebrate lineages. In conjunction with these changes, olfactory inputs to the telencephalic pallium were reduced in several different lineages, and this reduction was associated with the emergence of pallial regions that process non-olfactory sensory inputs. These conclusions cast doubt on the widely held assumption that all vertebrate nervous systems are built according to a single, common plan. Instead, the book encourages readers to view both species similarities and differences as fundamental to a comprehensive understanding of nervous systems.

The main topic of the book is a reconstruction of the evolution of nervous systems and brains as well as of mental-cognitive abilities, in short “intelligence” from simplest organisms to humans. It investigates to which extent the two are correlated. One central topic is the alleged uniqueness of the human brain and human intelligence and mind. It is discussed which neural features make certain animals and humans intelligent and creative: Is it absolute or relative brain size or the size of “intelligence centers” inside the brains, the number of nerve cells inside the brain in total or in such “intelligence centers” decisive for the degree of intelligence, of mind and eventually consciousness? And which are the driving forces behind these processes? Finally, it is asked what all this means for the classical problem of mind-brain relationship and for a naturalistic theory of mind.

A new theory of Intelligence, from a renowned and highly respected writer on brains and evolution What constitutes consciousness or intelligence? This is a question that has proved to philosophers to be an intellectual dead-end. Now William Calvin, by looking closely at animal and human intelligence and a wide range of evolutionary evidence, has broken new ground that will help us understand mental illness and illuminate the whole notion of what it is to be a person. Calvin begins by asking what intelligence is. He moves to the Why of intelligence, where evidence from chimpanzees is important, before coming to the all-important How of intelligence, the cerebral codes and Darwinian processes that operate within seconds to produce intelligent thought and action.

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.
