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.

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.

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.

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.

How and why did humans get to be so clever and thoughtful? The beginning of the Stone Age, marked by the invention of stone tools, has traditionally dominated discussions about the origin and evolution of human intelligence. However, feminist anthropologists have long theorized that the first tools were actually nests, slings, and baskets that would not have survived in the archaeological record.In The Botanic Age, leading evolutionary anthropologist Dean Falk argues that millions of years of weaving botanical materials and woodworking preceded the Stone Age, facilitating the basic neurological underpinnings for humankind’s later creative and technological inventions. She further suggests that mothers and infants may hold the key to understanding a series of events that eventually kindled the emergence of advanced cognitive abilities, including language and music.The Botanic Age takes readers millions of years into the past to a time before our relatives began living full-time on the ground. From stationary hominin sleeping trees in Africa to beached trees on the shores of Indonesia, the impact of the Botanic Age on hominin evolution was far-reaching. Only from this vantage point "in the trees" can we really begin to understand how and why our ancestors evolved – and how we became human.
