Synthesized answer
Based solely on the provided passages, I can explain that the book's key concepts involve a critical examination of biological determinism. The author, Richard Lewontin, identifies a "pervasive error that confuses the genetic state of an organism with its total physical and psychic nature as a human being" [3]. The book argues against the temptation to look to biology for explanations of everything about our physical, mental, and social lives [2].
The passages also indicate that the book provides "lucid expositions of the exact state of current scientific knowledge—not only what we do know, but what we don't and maybe won't anytime soon" [2]. Subjects discussed include heredity, natural selection, evolutionary psychology, and the Human Genome Project [2]. However, the passages do not provide a detailed explanation of these concepts themselves, only that the book offers sharp criticisms of overreaching scientific claims related to them [3].

enetically modified food and the completion of the Human Genome Project. It is an indispensable guide to the most controversial issues in the life sciences today.
with lucid expositions of the exact state of current scientific knowledge—not only what we do know, but what we don't and maybe won't anytime soon. Among the subjects he discusses are heredity and natural selection, evolutionary psychology and altruism, nineteenth-century naturalist novels, sex surveys, cloning, and the Human Genome Project. In each case he casts an ever-vigilant and deflationary eye on the temptation to look to biology for explanations of everything we want to know about our physical, mental, and social lives. These essays—several of them updated with epilogues that take…
Title: It Ain't Necessarily So by Richard Lewontin Description: Is our nature—as individuals, as a species—determined by our evolution and encoded in our genes? If we unravel the protein sequences of our DNA, will we gain the power to cure all of our physiological and psychological afflictions and even to solve the problems of our society? Today biologists—especially geneticists—are proposing answers to questions that have long been asked by philosophy or faith or the social sciences. Their work carries the weight of scientific authority and attracts widespread public attention, but it is…
