Dean Falk

"Falk explains how the act of walking upright permitted brain size to begin increasing dramatically in our early ancestors. Her "radiator theory" demonstrates that once they developed the ability to cool cranial blood through vascular changes associated with bi-pedalism, the constraint that limited brain size disappeared. And what did 2 million years of bigger brains produce? The last chapter summarizes Falk's ideas on human cognitive and conscious capacities for the future."--BOOK JACKET.

"With wit and authority, Falk tells the parallel stories of two fossil discoveries that surprised the world, revealing the larger significance of these finds. Her lively recounting combines new historical research with her first-hand involvement in controversial interpretations."—Pat Shipman, author of The Animal Connection and The Man Who Found the Missing Link “An absorbing and engagingly personal account, by a leading participant, of two of the major “brain wars” that have raged along the path to our current understanding of human evolution.”--Ian Tattersall, author of The Fossil Trail and Human Origins “In The Fossil Chronicles, Falk engages us with a ‘tale of two brains’. While navigating the surfaces of these ancient brains, she reveals the convolutions of scientific controversies and how personalities and paleopolitics shape the ways we think about human evolution.”—Nina G. Jablonski, author of Skin: A Natural History

How Two Controversial Discoveries Changed Our View of Human Evolution

The Fossil Chronicles

Eve Penelope Schofield

In this unusual book an evolutionary anthropologist and her coauthor/granddaughter, who has Asperger syndrome, examine the emergence and spread of Asperger syndrome and other forms of high-functioning autism. The authors speak to readers with autism, parents, teachers, clinicians, psychologists, psychiatrists, other health-care providers, autism researchers, evolutionary biologists, geneticists, paleoanthropologists, and people who simply enjoy reading about science. Using the latest findings regarding brain evolution and the neurological, genetic, and cognitive underpinnings of autistic individuals at the high end of the spectrum, Falk theorizes that many characteristics associated with Asperger syndrome are by-products of the evolution of advanced mental processing. She explores the origins of autism, whether it is currently evolving, how it differs in males and females, and whether it is a global phenomenon. Additionally, Eve Schofield, who was diagnosed with Asperger syndrome as a child, provides firsthand accounts of what it is like to grow up as an "Aspie."

Primate Diversity

Este Armstrong

Given the past decade's explosion of neurobiological and paleontologi cal data and their increasingly sophisticated analyses, interdisciplinary syntheses between these two broad disciplines are of value and interest to many different scientists. The collected papers of this volume will appeal to students of primate and hominid evolution, neuroscientists, sociobiolo gists, and other behaviorists who seek a better understanding of the substrates of primate, including human, behavior. Each species of living primates represents an endpoint in evolution, but comparative neurologists can produce approximate evolutionary se quences by careful analyses of representative series. Because nervous tissue does not fossilize, only a comparison of structures and functions among extant primates can be used to investigate the fine details of primate bra~n evolution. Paleoneurologists, who directly examine the fossil record via endocasts or cranial capacities of fossil skulls, can best provide information about gross details, such as changes in brain size or sulcal patterns, and determine when they occurred. Physical anthropologists and paleontologists have traditionally relied more on paleoneurology, whereas neuroscientists and psychologists have relied more on comparative neurology. This division has been a detriment to the advancement of these fields and to the conceptual bases of primate brain evolution. Both methods are important and a synthesis is desirable. To this end, two symposia were held in 1980--one at the meeting of the American Association of Physical Anthro pologists in Niagara Falls, U. S. A. , and one at the precongressional meeting of the International Primatological Society in Torino, Italy.

Methods and Concepts

Primate Brain Evolution

Kathleen R. Gibson

Studies of brain evolution have moved rapidly in recent years, building on the pioneering research of Harry J. Jerison. This book provides reviews of primate (including human) brain evolution. The book is divided into two sections, the first gives new perspectives on the developmental, physiological, dietary and behavioural correlates of brain enlargement. It has long been recognized, however, that brains do not merely enlarge globally as they evolve, but that their cortical and internal organization also changes in a process known as reorganization. Species-specific adaptations therefore have neurological substrates that depend on more than just overall brain size. The second section explores these neurological underpinnings for the senses, adaptations and cognitive abilities that are important for primates. With a prologue by Stephen J. Gould and an epilogue by Harry J. Jerison, this is an important reference work for all those working on brain evolution in primates.

Evolutionary Anatomy of the Primate Cerebral Cortex

Scientists have long theorized that abstract, symbolic thinking evolved to help humans negotiate such classically male activities as hunting, tool making, and warfare, and eventually developed into spoken language. In Finding Our Tongues, Dean Falk overturns this established idea, offering a daring new theory that springs from a simple observation: parents all over the world, in all cultures, talk to infants by using baby talk or ''Motherese.'' Falk shows how Motherese developed as a way of reassuring babies when mothers had to put them down in order to do work. The melodic vocalizations of early Motherese not only provided the basis of language but also contributed to the growth of music and art. Combining cutting-edge neuroscience with classic anthropology, Falk offers a potent challenge to conventional wisdom about the emergence of human language.

Mothers, Infants and the Origins of Language

Finding Our Tongues

Two discoveries of early human relatives, one in 1924 and one in 2003, radically changed scientific thinking about our origins. Dean Falk, a pioneer in the field of human brain evolution, offers this fast-paced insider’s account of these discoveries, the behind-the-scenes politics embroiling the scientists who found and analyzed them, and the academic and religious controversies they generated. The first is the Taung child, a two-million-year-old skull from South Africa that led anatomist Raymond Dart to argue that this creature had walked upright and that Africa held the key to the fossil ancestry of our species. The second find consisted of the partial skeleton of a three-and-a-half-foot-tall woman, nicknamed Hobbit, from Flores Island, Indonesia. She is thought by scientists to belong to a new, recently extinct species of human, but her story is still unfolding. Falk, who has studied the brain casts of both Taung and Hobbit, reveals new evidence crucial to interpreting both discoveries and proposes surprising connections between this pair of extraordinary specimens.
