Genetic Reconstruction of the Past describes how DNA analysis can be used to make inferences not only in criminal cases but also about the ancient past. Part One focuses on forensic genetics and crime scenes. It gives an in-depth account of how we developed PCR, and used it on DNA evidence for the first time in a US court case in 1986; the first post-conviction exoneration; and the first identification of a missing person. Part Two discusses how the same DNA technology and data can also illuminate the ancient past, the history of human origins and migrations.

The same DNA technology that allows the analysis of a hair or tiny blood spot at a crime scene also enables sequencing the DNA of a bone fragment from a Neanderthal skeleton. Comparing the DNA sequences of different samples and comparing the frequency of specific genetic variants in different populations is a critical part of both forensic and evolutionary investigations. These two fields share a common goal: solving historical mysteries. The book discusses the intrinsic human curiosity about our origins and the desire to solve crimes and seek justice and how the recent emergence of DNA analysis has transformed our ability to address these universal human aspirations. The unifying theme of the book is the recently developed capacity to use DNA sequence information to make inferences about historical events. Part One is a discussion of how DNA analysis can reconstruct the recent past, in particular, the events that transpired at the scene of a crime. Part Two is a discussion of the application of DNA analysis to reconstructing the ancient past, using DNA sequences from human samples as well as from fossil remains to study the evolution of the human species and the historical relationships among contemporary and extinct human populations. Erlich discuss how he, along with his colleagues at Cetus Corp in the mid-1980s developed the PCR (polymerase chain reaction) technology of specific DNA amplification, a method of synthesizing millions of copies of a specific targeted DNA sequence and applied it to address forensic and evolutionary questions. It is this capacity, that has transformed both forensic science and evolutionary biology and has led to both the identification-and exoneration-of criminal suspects and a deeper understanding of human evolution. These techniques, now widely used, were applied in the first DNA criminal case, the first exoneration case, and the first identification of a missing person. Discussions on the history and the many remaining contentious issues in forensic DNA analysis in Part One are organized around several specific criminal cases, while the book tries to convey the spirit of "doing science."

This is a detailed history of one of the most important and dramatic episodes in modern science, recounted from the novel vantage point of the dawn of the information age and its impact on representations of nature, heredity, and society. Drawing on archives, published sources, and interviews, the author situates work on the genetic code (1953-70) within the history of life science, the rise of communication technosciences (cybernetics, information theory, and computers), the intersection of molecular biology with cryptanalysis and linguistics, and the social history of postwar Europe and the United States. Kay draws out the historical specificity in the process by which the central biological problem of DNA-based protein synthesis came to be metaphorically represented as an information code and a writing technologyand consequently as a book of life. This molecular writing and reading is part of the cultural production of the Nuclear Age, its power amplified by the centuries-old theistic resonance of the book of life metaphor. Yet, as the author points out, these are just metaphors: analogies, not ontologies. Necessary and productive as they have been, they have their epistemological limitations. Deploying analyses of language, cryptology, and information theory, the author persuasively argues that, technically speaking, the genetic code is not a code, DNA is not a language, and the genome is not an information system (objections voiced by experts as early as the 1950s). Thus her historical reconstruction and analyses also serve as a critique of the new genomic biopower. Genomic textuality has become a fact of life, a metaphor literalized, she claims, as human genome projects promise new levels of control over life through the meta-level of information: control of the word (the DNA sequences) and its editing and rewriting. But the author shows how the humbling limits of these scriptural metaphors also pose a challenge to the textual and material mastery of the genomic book of life.

From the first dog to the first beefalo, from farming to CRISPR, the human history of remaking nature When the 2020 Nobel Prize was awarded to the inventors of CRISPR, the revolutionary gene-editing tool, it underlined our amazing and apparently novel powers to alter nature. But as biologist Beth Shapiro argues in Life as We Made It, this phenomenon isn’t new. Humans have been reshaping the world around us for ages, from early dogs to modern bacteria modified to pump out insulin. Indeed, she claims, reshaping nature—resetting the course of evolution, ours and others’—is the essence of what our species does. In exploring our evolutionary and cultural history, Shapiro finds a course for the future. If we have always been changing nature to help us survive and thrive, then we need to avoid naive arguments about how we might destroy it with our meddling, and instead ask how we can meddle better. Brilliant and insightful, Life as We Made It is an essential book for the decades to come.

In this New York Times bestseller and longlist nominee for the National Book Award, “our greatest living chronicler of the natural world” (The New York Times), David Quammen explains how recent discoveries in molecular biology affect our understanding of evolution and life’s history. In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field—the study of life’s diversity and relatedness at the molecular level—is horizontal gene transfer (HGT), or the movement of genes across species lines. It turns out that HGT has been widespread and important; we now know that roughly eight percent of the human genome arrived sideways by viral infection—a type of HGT. In The Tangled Tree, “the grandest tale in biology….David Quammen presents the science—and the scientists involved—with patience, candor, and flair” (Nature). We learn about the major players, such as Carl Woese, the most important little-known biologist of the twentieth century; Lynn Margulis, the notorious maverick whose wild ideas about “mosaic” creatures proved to be true; and Tsutomu Wantanabe, who discovered that the scourge of antibiotic-resistant bacteria is a direct result of horizontal gene transfer, bringing the deep study of genome histories to bear on a global crisis in public health. “David Quammen proves to be an immensely well-informed guide to a complex story” (The Wall Street Journal). In The Tangled Tree, he explains how molecular studies of evolution have brought startling recognitions about the tangled tree of life—including where we humans fit upon it. Thanks to new technologies, we now have the ability to alter even our genetic composition—through sideways insertions, as nature has long been doing. “The Tangled Tree is a source of wonder….Quammen has written a deep and daring intellectual adventure” (The Boston Globe).

Hailed as a breakthrough in the understanding of human evolution, The History and Geography of Human Genes offers the first full-scale reconstruction of where human populations originated and the paths by which they spread throughout the world. By mapping the worldwide geographic distribution of genes for over 110 traits in over 1800 primarily aboriginal populations, the authors charted migrations and devised a clock by which to date evolutionary history. This monumental work is now available in a more affordable paperback edition without the myriad illustrations and maps, but containing the full text and partial appendices of the authors' pathbreaking endeavor.

An exciting and accessible new view of the evolution of human and animal life on Earth. From the author of national bestseller, Your Inner Fish, this extraordinary journey of discovery spans centuries, as explorers and scientists seek to understand the origins of life's immense diversity. “Fossils, DNA, scientists with a penchant for suits of armor—what’s not to love?”—BBC Wildlife Magazine Over billions of years, ancient fish evolved to walk on land, reptiles transformed into birds that fly, and apelike primates evolved into humans that walk on two legs, talk, and write. For more than a century, paleontologists have traveled the globe to find fossils that show how such changes have happened. We have now arrived at a remarkable moment—prehistoric fossils coupled with new DNA technology have given us the tools to answer some of the basic questions of our existence: How do big changes in evolution happen? Is our presence on Earth the product of mere chance? This new science reveals a multibillion-year evolutionary history filled with twists and turns, trial and error, accident and invention. In Some Assembly Required, Neil Shubin takes readers on a journey of discovery spanning centuries, as explorers and scientists seek to understand the origins of life's immense diversity.
