Genes And Behavior

Provides a broad snapshot of recent findings showing how the environment and genes influence behavior The great debate of nature versus nurture rages on — but our understanding of the genetic basis of many behaviors has expanded over the last decade, and there is now very good evidence showing that seemingly complex behaviours can have relatively simple genetic underpinnings, but also that most behaviours have very complicated genetic and environmental architecture. Studies have also clearly shown that behaviors, and other traits, are influenced not just by genes and the environment, but also by the statistical interaction between the two. This book aims to end the nature versus nurture argument by showing that behaviors are nature and nurture and the interaction between the two, and by illustrating how single genes can explain some of the variation in behaviors even when they are seemingly complex. Genes and Behaviour: Beyond Nature-Nurture puts to rest the nature versus nurture dichotomy, providing an up-to-date synopsis of where we are, how far we've come and where we are headed. It considers the effects of a dual-inheritance of genes and culture, and genes and social environment, and highlights how indirect genetic effects can affect the evolution of behavior. It also examines the effect of non-self genes on the behavior of hosts, shines a light on the nature and nurturing of animal minds and invites us to embrace all the complexity nature and nurture generates, and more. Explores exciting new findings about behavior and where we go from here Features contributions by top scholars of the subject Seeks to end the nature versus nurture debate forever Genes and Behaviour: Beyond Nature-Nurture is a unique, and eye-opening read that will appeal to Ph.D. Students, post-doctoral fellows, and researchers in evolution and behavior. Additionally, the book will also be of interest to geneticists, sociologists and philosophers.

Over the past century, we have made great strides in reducing rates of disease and enhancing people's general health. Public health measures such as sanitation, improved hygiene, and vaccines; reduced hazards in the workplace; new drugs and clinical procedures; and, more recently, a growing understanding of the human genome have each played a role in extending the duration and raising the quality of human life. But research conducted over the past few decades shows us that this progress, much of which was based on investigating one causative factor at a time—often, through a single discipline or by a narrow range of practitioners—can only go so far. Genes, Behavior, and the Social Environment examines a number of well-described gene-environment interactions, reviews the state of the science in researching such interactions, and recommends priorities not only for research itself but also for its workforce, resource, and infrastructural needs.

Genes, Brain Function, and Behavior offers a concise description of the nervous system that processes sensory input and initiates motor movements. It reviews how behaviors are defined and measured, and how experts decide when a behavior is perturbed and in need of treatment. Behavioral disorders that are clearly related to a defect in a specific gene are reviewed, and the challenges of understanding complex traits such as intelligence, autism and schizophrenia that involve numerous genes and environmental factors are explored. New methods of altering genes offer hope for treating or even preventing difficulties that arise in our genes. This book explains what genes are, what they do in the nervous system, and how this impacts both brain function and behavior. Presents essential background, facts, and terminology about genes, brain function, and behavior Builds clear explanations on this solid foundation while minimizing technical jargon Explores in depth several single-gene and chromosomal neurological disorders Derives lessons from these clear examples and highlights key lessons in boxes Examines the intricacies of complex traits that involve multiple genetic and environmental factors by applying lessons from simpler disorders Explains diagnosis and definition Includes a companion website with Powerpoint slides and images for each chapter for instructors and links to resources

In this major new book, eminent scientist Professor Sir Michael Rutter gets behind the hype of the behavioral genetics debate to provide a balanced and authoritative overview of the genetic revolution and its implications for understanding human behavior. Written by one of the world's leading figures in child psychology and psychiatry, Professor Sir Michael Rutter Provides non-technical explanation of genetics to diffuse the sensational debates surrounding the topic Sets out in layman's terms what genes do, how much is nature and how much is nurture Argues that nature and nurture are not truly separate and gives examples of how the two interact Looks at the implications of genetic findings for policy and practice The book will inform public debate about the implications of the Human Genome Project and, more broadly, the field of genetic science

This book is a unique introduction to behavioral genetics, which offers unparalleled insights into how the topic is probed using evidence from humans and the major model organisms. It also demonstrates the major impact that neurobiology is having on our understanding of the field, to give a true depiction of behavioral genetics in the 21st century.

How tiny variations in our personal DNA can determine how we look, how we behave, how we get sick, and how we get well. News stories report almost daily on the remarkable progress scientists are making in unraveling the genetic basis of disease and behavior. Meanwhile, new technologies are rapidly reducing the cost of reading someone's personal DNA (all six billion letters of it). Within the next ten years, hospitals may present parents with their newborn's complete DNA code along with her footprints and APGAR score. In Genetic Twists of Fate, distinguished geneticists Stanley Fields and Mark Johnston help us make sense of the genetic revolution that is upon us. Fields and Johnston tell real life stories that hinge on the inheritance of one tiny change rather than another in an individual's DNA: a mother wrongly accused of poisoning her young son when the true killer was a genetic disorder; the screen siren who could no longer remember her lines because of Alzheimer's disease; and the president who was treated with rat poison to prevent another heart attack. In an engaging and accessible style, Fields and Johnston explain what our personal DNA code is, how a few differences in its long list of DNA letters makes each of us unique, and how that code influences our appearance, our behavior, and our risk for such common diseases as diabetes or cancer.

How Genes Influence Behavior takes a personal and lively approach to the study of behavioral genetics, providing an up-to-date and accessible introduction to a variety of approaches and their application to a wide range of disorders, and modeling a critical approach to both methods andresults.This second edition includes additional biology content to help students understand the biological foundations of the field, while maintaining an appropriate focus on the main issues of relevance to psychology students; updates coverage of genomic technologies and their applications; and covers awider range of disorders, including autism spectrum disorder, eating disorders, and intellectual disability. A new final chapter guides students through a range of quantitative approaches using worked examples that relate directly to cases and examples used earlier in the text, and addresses currentissues arising from debates around reproducibility.The online resources that accompany this book include:For students* Multiple choice questions for students to check their threshold knowledge* Data sets for students to manipulate, so that they can apply what they have learnedFor lecturers* Figures and tables from the book, ready to download

Books such as Richard Dawkins's The Selfish Gene have aroused fierce controversy by arguing for the powerful influence of genes on human behavior. But are we entirely at the mercy of our chromosomes? In Are We Hardwired?, scientists William R. Clark and Michael Grunstein say the answer is both yes--and no. The power and fascination of Are We Hardwired? lie in their explanation of that deceptively simple answer. Using eye-opening examples of genetically identical twins who, though raised in different families, have had remarkably parallel lives, the authors show that indeed roughly half of human behavior can be accounted for by DNA. But the picture is quite complicated. Clark and Grunstein take us on a tour of modern genetics and behavioral science, revealing that few elements of behavior depend upon a single gene; complexes of genes, often across chromosomes, drive most of our heredity-based actions. To illustrate this point, they examine the genetic basis, and quirks, of individual behavioral traits--including aggression, sexuality, mental function, eating disorders, alcoholism, and drug abuse. They show that genes and environment are not opposing forces; heredity shapes how we interpret our surroundings, which in turn changes the very structure of our brain. Clearly we are not simply puppets of either influence. Perhaps most interesting, the book suggests that the source of our ability to choose, to act unexpectedly, may lie in the chaos principle: the most minute differences during activation of a single neuron may lead to utterly unpredictable actions. This masterful account of the nature-nurture controversy--at once provocative and informative--answers some of our oldest questions in unexpected new ways
