Evolutionary Perspectives On Infancy

This unique volume is one of the first of its kind to examine infancy through an evolutionary lens, identifying infancy as a discrete stage during which particular types of adaptations arose as a consequence of certain environmental pressures. Infancy is a crucial time period in psychological development, and evolutionary psychologists are increasingly recognizing that natural selection has operated on all stages of development, not just adulthood. The volume addresses this crucial change in perspective by highlighting research across diverse disciplines including developmental psychology, evolutionary developmental psychology, anthropology, sociology, nutrition, and primatology. Chapters are grouped into four sections: Theoretical Underpinnings Brain and Cognitive Development Social/Emotional Development Life and Death Evolutionary Perspectives on Infancy sheds new light on our understanding of the human brain and the environments responsible for shaping the brain during early stages of development. This book will be of interest to evolutionary psychologists and developmental psychologists, biologists, and anthropologists, as well as scholars more broadly interested in infancy.

Originally published in 1974, this volume is primarily devoted to what is known about human infancy from an ethological, evolutionary viewpoint. Included are discussions of pan-specific traits, presumably shared by all infants; individual genetic variations on these behaviours (as judged by twin-studies); sex differences, presumably shared by infants of all ethnic groups; and genetically based ethnic differences. However, the author favours neither biological determinism nor cultural determinism, and does not consider ‘interactionism’ to be a viable solution. Instead, a monistic position is taken, stressing the inseparability of the innate and the acquired, of genetics and environment, and of biology and culture. The heredity-environment issue is tackled head-on throughout the volume. The interaction between the two (an implied dualism) is described as a statistical abstraction from measured populations, while the position here is that heredity and environment are not separable in any single organism. In the same vein, the author argues that on logical grounds everything one does, every ‘cultural’ act, has within it some biological component.

Originally published in 1984, this book is a developmental psychology text with substantial evolutionary and cross-cultural work. It presents cognitive developmental issues, as well as personality, social and socialization issues, with an emphasis on culture. It also includes education-related research, such as material on schools, reading, mathematics, and IQ.

Natural selection has operated as strongly or more so on the early stages of the lifespan as on adulthood. One evolved feature of human childhood is high levels of behavioral, cognitive, and neural plasticity, permitting children to adapt to a wide range of physical and social environments. Taking an evolutionary perspective on infancy and childhood provides a better understanding of contemporary human development, predicting and understanding adult behavior, and explaining how changes in the early development of our ancestors produced contemporary Homo sapiens.

The story of human evolution has been told hundreds of times, each time with a focus that seems most informative of the teller. No matter how it is told the primary characters are rarely mothers and infants. Darwin argued survival, but today we know that reproduction is what evolution is all about. Centering on this, Trevathan focuses on birth, which gives the study of human evolution a crucial new dimension.Unique among mammals, humans are bipedal. The evolution of bipedalism required fundamental changes in the pelvis and resulted in a narrow birth canal. Humans are also large-brained animals, which means that birth is much more challenging for our species than for most other animals. The result of this mismatch of large head and narrow pelvis is that women are highly dependent on assistance at birth and their babies are born in an unusually undeveloped state when the brain is still small. Human Birth discusses how the birth process has evolved and ways in which human birth differs from birth in all other mammals.Human Birth is also concerned with mother-infant interaction immediately after birth. While working as a midwife trainee, Trevathan carefully documented the births of more than one hundred women and recorded maternal and infant behaviors during the first hour after birth. She suggests ways in which the interactions served not only to enhance mother-infant bonding, but also to ensure survival in the evolutionary past. With clarity and compelling logic Trevathan argues that modern birth practices often fail to meet evolved needs of women and infants and suggests changes that could lead to better birth experiences. This paperback edition includes a new introduction by the author.

Evolutionary Perspectives on Human Development's Comprehensive coverage on current thinking about the impact of evolutionary theory on human development provides students with the most thorough grounding available in this area. Contributions by leading scholars and researchers expose students first-hand to the thinking of widely recognized experts and the exciting contributions they have been making to this field. To ensure accessibility in classroom settings, chapters have been written according to uniform guidelines for length and format, with cross-references between chapters and a style appropriate to upper-division undergraduate and beginning graduate psychology students. To further facilitate the use of Evolutionary Perspectives on Human Development as supplemental classroom reading, the volume editors provide an introductory overview chapter and a concluding chapter that sums up the book.

This collection is the first to specifically address our current understanding of the evolution of human childhood, which in turn significantly affects our interpretations of the evolution of family formation, social organization, cultural transmission, cognition, ontogeny, and the physical and socioemotional needs of children. Moreover, the importance of studying the evolution of childhood has begun to extend beyond academic modeling and into real-world applications for maternal and child health and well-being in contemporary populations around the world. Combined, the chapters show that what we call childhood is culturally variable yet biologically based and has been critical to the evolutionary success of our species; the significance of integrating childhood into models of human life history and evolution cannot be overstated. This volume further demonstrates the benefits of interdisciplinary investigation and is sure to spur further interest in the field.

It presents LCHD as an innovative field with a sound theoretical framework for understanding wellness and disease from a lifespan perspective, replacing previous medical, biopsychosocial, and early genomic models of health. Interdisciplinary chapters discuss major health concerns (diabetes, obesity), important less-studied conditions (hearing, kidney health), and large-scale issues (nutrition, adversity) from a lifespan viewpoint. In addition, chapters address methodological approaches and challenges by analyzing existing measures, studies, and surveys. The book concludes with the editors’ research agenda that proposes priorities for future LCHD research and its application to health care practice and health policy. Topics featured in the Handbook include: The prenatal period and its effect on child obesity and metabolic outcomes. Pregnancy complications and their effect on women’s cardiovascular health. A multi-level approach for obesity prevention in children. Application of the LCHD framework to autism spectrum disorder. Socioeconomic disadvantage and its influence on health development across the lifespan. The importance of nutrition to optimal health development across the lifespan. The Handbook of Life Course Health Development is a must-have resource for researchers, clinicians/professionals, and graduate students in developmental psychology/science; maternal and child health; social work; health economics; educational policy and politics; and medical law as well as many interrelated subdisciplines in psychology, medicine, public health, mental health, education, social welfare, economics, sociology, and law.
