You've probably seen it before: a human brain dramatically lit from the side, the camera circling it like a helicopter shot of Stonehenge, and a modulated baritone voice exalting the brain's elegant design in reverent tones.

To which this book says: Pure nonsense. In a work at once deeply learned and wonderfully accessible, the neuroscientist David Linden counters the widespread assumption that the brain is a paragon of design--and in its place gives us a compelling explanation of how the brain's serendipitous evolution has resulted in nothing short of our humanity. A guide to the strange and often illogical world of neural function, The Accidental Mind shows how the brain is not an optimized, general-purpose problem-solving machine, but rather a weird agglomeration of ad-hoc solutions that have been piled on through millions of years of evolutionary history. Moreover, Linden tells us how the constraints of evolved brain design have ultimately led to almost every transcendent human foible: our long childhoods, our extensive memory capacity, our search for love and long-term relationships, our need to create compelling narrative, and, ultimately, the universal cultural impulse to create both religious and scientific explanations. With forays into evolutionary biology, this analysis of mental function answers some of our most common questions about how we've come to be who we are.

Popular understanding holds that genetic changes create cancer. James DeGregori uses evolutionary principles to propose a new way of thinking about cancer’s occurrence. Cancer is as much a disease of evolution as it is of mutation, one in which mutated cells outcompete healthy cells in the ecosystem of the body’s tissues. His theory ties cancer’s progression, or lack thereof, to evolved strategies to maximize reproductive success.

Through natural selection, humans evolved genetic programs to maintain bodily health for as long as necessary to increase the odds of passing on our genes—but not much longer. These mechanisms engender a tissue environment that favors normal stem cells over precancerous ones. Healthy tissues thwart cancer cells’ ability to outcompete their precancerous rivals. But as our tissues age or accumulate damage from exposures such as smoking, normal stem cells find themselves less optimized to their ecosystem. Cancer-causing mutations can now help cells adapt to these altered tissue environments, and thus outcompete normal cells. Just as changes in a species’ habitat favor the evolution of new species, changes in tissue environments favor the growth of cancerous cells.

DeGregori’s perspective goes far in explaining who gets cancer, when it appears, and why. While we cannot avoid mutations, it may be possible to sustain our tissues’ natural and effective system of defense, even in the face of aging or harmful exposures. For those interested in learning how cancers arise within the human body, the insights in Adaptive Oncogenesis offer a compelling perspective.

This book offers a unique insider's perspective on the unfolding discovery of a crucial link in our evolution: Proconsul, a fossil ape named whimsically after a performing chimpanzee called Consul.

The Ape in the Tree is written in the voice of Alan Walker, whose involvement with Proconsul began when his graduate supervisor analyzed the tree-climbing adaptations in the arm and hand of this extinct creature. Today, Proconsul is the best-known fossil ape in the world.

The history of ideas is set against the vivid adventures of Walker's fossil-hunting expeditions in remote regions of Africa, where the team met with violent thunderstorms, dangerous wildlife, and people isolated from the Western world. Analysis of the thousands of new Proconsul specimens they recovered provides revealing glimpses of the life of this last common ancestor between apes and humans.

The attributes of Proconsul have profound implications for the very definition of humanness. This book speaks not only of an ape in a tree but also of the ape in our tree.

In this masterwork, Russell H. Tuttle synthesizes a vast research literature in primate evolution and behavior to explain how apes and humans evolved in relation to one another, and why humans became a bipedal, tool-making, culture-inventing species distinct from other hominoids. Along the way, he refutes the influential theory that men are essentially killer apes--sophisticated but instinctively aggressive and destructive beings.

Situating humans in a broad context, Tuttle musters convincing evidence from morphology and recent fossil discoveries to reveal what early primates ate, where they slept, how they learned to walk upright, how brain and hand anatomy evolved simultaneously, and what else happened evolutionarily to cause humans to diverge from their closest relatives. Despite our genomic similarities with bonobos, chimpanzees, and gorillas, humans are unique among primates in occupying a symbolic niche of values and beliefs based on symbolically mediated cognitive processes. Although apes exhibit behaviors that strongly suggest they can think, salient elements of human culture--speech, mating proscriptions, kinship structures, and moral codes--are symbolic systems that are not manifest in ape niches.

This encyclopedic volume is both a milestone in primatological research and a critique of what is known and yet to be discovered about human and ape potential.

In the final decades of the twentieth century, the advent of evolutionary developmental biology (evo-devo) offered a revolutionary new perspective that transformed the classical neo-Darwinian, gene-centered study of evolution. In The Architecture of Evolution, Marco Tamborini demonstrates how this radical innovation was made possible by the largely forgotten study of morphology. Despite the key role morphology played in the development of evolutionary biology since the 1940s, the architecture of organisms was excluded from the Modern Evolutionary Synthesis. And yet, from the beginning of the twentieth century to the 1970s and ’80s, morphologists sought to understand how organisms were built and how organismal forms could be generated and controlled. The generation of organic form was, they believed, essential to understanding the mechanisms of evolution. Tamborini explores how the development of evo-devo and the recent organismal turn in biology involved not only the work of morphologists but those outside the biological community with whom they exchanged their data, knowledge, and practices. Together with architects and engineers, they worked to establish a mathematical and theoretical basis for the study of organic form as a mode of construction, developing and reinterpreting important notions that would play a central role in the development of evolutionary developmental biology in the late 1980s. This book sheds light not only on the interdisciplinary basis for many of the key concepts in current developmental biology but also on contributions to the study of organic form outside the English-speaking world.

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.

The evolutionist Ernst Mayr considered August Weismann “one of the great biologists of all time.” Yet the man who formulated the germ plasm theory—that inheritance is transmitted solely through the nuclei of the egg and sperm cells—has not received an in-depth historical examination. August Weismann reintroduces readers to a towering figure in the life sciences. In this first full-length biography, Frederick Churchill situates Weismann in the swirling intellectual currents of his era and demonstrates how his work paved the way for the modern synthesis of genetics and evolution in the twentieth century.

In 1859 Darwin’s tantalizing new idea stirred up a great deal of activity and turmoil in the scientific world, to a large extent because the underlying biological mechanisms of evolution through natural selection had not yet been worked out. Weismann’s achievement was to unite natural history, embryology, and cell biology under the capacious dome of evolutionary theory. In his major work on the germ plasm (1892), which established the material basis of heredity in the “germ cells,” Weismann delivered a crushing blow to Lamarck’s concept of the inheritance of acquired traits.

In this deeply researched biography, Churchill explains the development of Weismann’s pioneering work based on cytology and embryology and opens up an expanded history of biology from 1859 to 1914. August Weismann is sure to become the definitive account of an extraordinary life and career.
