Neurophysiologist John Allman draws on the wealth of new findings in molecular genetics and paleoanthropology to trace the history of brain evolution from the simplest of animals to human beings. In doing so, he explores the forces and mechanisms that have influenced evolutionary development, including climatic change, the energy requirements of large brains and the invention of the extended family in early humans.

What's the big deal about big brains? They're a costly enhancement, says neurobiologist John Allman in Evolving Brains. "Animals with big brains are rare," he stresses. "If brains enable animals to adapt to changing environments, why is it that so few animals have large brains? The reason is that big brains are very expensive." He examines the whys and wherefores of large-brain evolution, and draws out the connections between large brains and long lives; shows why major evolutionary advances are often made by small predators; makes you appreciate why mammals, burdened by the cost of warm-bloodedness, were unable to unseat the dinosaurs; and more. So, while large brains such as the ones we humans enjoy may give survival advantages to individuals, some species have done (and did) just fine for millions of years with pea brains.
Rather than talking only about cells, circuits, neurotransmitters, and genes, or gliding up to the ethereal regions of psychology and philosophy, Allman looks at the whole organism--the "middle-sized, middle-distanced objects," as Willard Van Orman Quine said. Evolving Brains is full of interesting scientific tidbits, only rarely becoming tangled in the thicket of jargon. --Mary Ellen CurtinAbout the Author:
John Morgan Allman is Hixon Professor of Biology at the California Institute of Technology. He received his doctoral degree in anthropology and played a key role in the discovery that the visual cortex in primates comprises many areas that serve a multitude of functions. Dr. Allman received the Golden Brain Award from the Minerva Foundation for his research on how the brain represents visual information.
