(More customer reviews)One would expect an introductory textbook by these three scientists to be good, and it is. It covers behavioural and molecular methods, using examples from the authors' own work in psychiatric genetics. The field is put in historical context, with the false turnings explored, as well as the major breakthroughs. The authors take us on a journey through family, adoption and twin studies, on to the history of molecular psychiatric genetics, starting with the early, and usually unreplicated, linkage studies, through genome wide association studies and animal models using rodents and drosophila. Concepts are explained with a minimum of technical and statistical detail, making the book accessible to a wide readership. What sets this book apart from others on this topic are the personal and often witty accounts of doing research. Kendler's anecdote of a family study of schizophrenia in Ireland is particularly engaging, including an encounter with an elderly grandmother who expressed indignation that he should be driving around all over the place interviewing people to find out if mental illness ran in families. "'Why everybody knows that! Take the O'Donnells for example. They are as mad as can be and it goes back generations." (p. 12). One also gets a sense of the hard graft involved in doing research in this area: Kendler estimated that his study took 18 person years just to gather the data, and evidently required persistence and a willingness to work heroically antisocial hours by the research team.
Anyone contemplating a research career in molecular genetics would do well to read the paragraph on p 34-35 debunking popular assumptions about life in the laboratory: "A combination of intelligence and technology applied to taxing but interesting biological problems leads to ground-breaking discoveries that could cure disease or change our understanding of the universe." Well, no. The work is dull, repetitive, and usually unsuccessful. And if after years of work you do find something interesting, your laboratory head will ask: "Why is this finding wrong?". In fact, I suspect only really good laboratory heads do that - the bad ones rush gleefully into print, which is why the field is littered with nonreplicable findings. But as Flint et al point out, you need to ask it because it's embarrassing to publishing something that is wrong, your peers will do their best to find flaws in the work, and, most importantly, "it's only by publishing findings that are robust to any possible criticism that we'll make any progress". A refreshingly old-fashioned take on the scientific process that is all-too-often forgotten in the current climate where we're all encouraged to publish as much as we possibly can, and where a dramatic but non-replicable result may get you two papers in a high-impact journal: one for the original finding, and the other for the failure to replicate.

How important are genetic influences on behavior?How many genes influence an individual behavior, and how much influence does a single gene have? How do genes interact with the environment to influence the development of behavioral traits?What are the differences between humans and 'simpler' organisms when it comes to the genetic control of behavior? How Genes Influence Behavior is a unique introduction to behavioral genetics, which combines conceptual rigor with accessibility to answer questions such as these--answers that carry important implications for the nature of who we are. Offering unparalleled insights into how behavioral genetics is probed through real-world research, it considers evidence from humans and the major model organisms of mouse, fruit-fly and nematode worm to demonstrate how much of our current understanding of the genetic basis of human behavior stems from our exploration of other animals. Further, it uses these studies to connect the key themes of the book--the nature of gene action, and the inter-relationship of genetic and environmental influences on behavior-across organisms, highlighting key commonalities and differences.The book also shows 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. However, care is taken throughout not to overwhelm the reader with scientific detail. Instead, the authors make the book fun to read without sacrificing accuracy or devaluing the complexity of the subject matter: they 'personalize' the science, mixing more standard narrative with biographical details to make the subject come alive. With the media filled with talk of the discovery of genes 'for' an array of human behaviors, there has never been a more pressing need for today's students--tomorrow's researchers--to be equipped with a clear, balanced view of the field. How Genes Influence Behavior is the perfect guide for all students, delivered in the words of three researchers who have witnessed first-hand the emergence of this fascinating field, and whose own investigations have been central to our current understanding of it.Online Resource CentreFor Instructors* Figures from the book, available to downloadFor students* Hyperlinks to primary literature cited in the text
