Book Description
If Darwin were to examine the evidence today using modern science, would his conclusions be the same? Charles Darwin’s On the Origin of Species, published over 150 years ago, is considered one of history’s most influential books and continues to serve as the foundation of thought for evolutionary biology. Since Darwin’s time, however, new fields of science have immerged that simply give us better answers to the question of origins. With a Ph.D. in cell and developmental biology from Harvard University, Dr. Nathaniel Jeanson is uniquely qualified to investigate what genetics reveal about origins. The Origins Puzzle Comes Together If the science surrounding origins were a puzzle, Darwin would have had fewer than 15% of the pieces to work with when he developed his theory of evolution. We now have a much greater percentage of the pieces because of modern scientific research. As Dr. Jeanson puts the new pieces together, a whole new picture emerges, giving us a testable, predictive model to explain the origin of species. A New Scientific Revolution Begins Darwin’s theory of evolution may be one of science’s “sacred cows,” but genetics research is proving it wrong. Changing an entrenched narrative, even if it’s wrong, is no easy task. Replacing Darwin asks you to consider the possibility that, based on genetics research, our origins are more easily understood in the context of . . . In the beginning . . . God, with the timeline found in the biblical narrative of Genesis. There is a better answer to the origins debate than what we have been led to believe. Let the revolution begin! About the Author Dr. Nathaniel Jeanson is a scientist and a scholar, trained in one of the most prestigious universities in the world. He earned his B.S. in Molecular Biology and Bioinformatics from the University of Wisconsin-Parkside and his PhD in Cell and Developmental Biology from Harvard University. As an undergraduate, he researched the molecular control of photosynthesis, and his graduate work involved investigating the molecular and physiological control of adult blood stem cells. His findings have been presented at regional and national conferences and have been published in peer-reviewed journals, such as Blood, Nature, and Cell. Since 2009, he has been actively researching the origin of species, both at the Institute for Creation Research and at Answers in Genesis.

Book Description
The evolutionary history of life includes two primary components: phylogeny and timescale. Phylogeny refers to the branching order (relationships) of species or other taxa within a group and is crucial for understanding the inheritance of traits and for erecting classifications. However, a timescale is equally important because it provides a way to compare phylogeny directly with the evolution of other organisms and with planetary history such as geology, climate, extraterrestrialimpacts, and other features.The Timetree of Life is the first reference book to synthesize the wealth of information relating to the temporal component of phylogenetic trees. In the past, biologists have relied exclusively upon the fossil record to infer an evolutionary timescale. However, recent revolutionary advances in molecular biology have made it possible to not only estimate the relationships of many groups of organisms, but also to estimate their times of divergence with molecular clocks. The routineestimation and utilization of these so-called 'time-trees' could add exciting new dimensions to biology including enhanced opportunities to integrate large molecular data sets with fossil and biogeographic evidence (and thereby foster greater communication between molecular and traditional systematists). Theycould help estimate not only ancestral character states but also evolutionary rates in numerous categories of organismal phenotype; establish more reliable associations between causal historical processes and biological outcomes; develop a universally standardized scheme for biological classifications; and generally promote novel avenues of thought in many arenas of comparative evolutionary biology.This authoritative reference work brings together, for the first time, experts on all major groups of organisms to assemble a timetree of life. The result is a comprehensive resource on evolutionary history which will be an indispensable reference for scientists, educators, and students in the life sciences, earth sciences, and molecular biology. For each major group of organism, a representative is illustrated and a timetree of families and higher taxonomic groups is shown. Basic aspects ofthe evolutionary history of the group, the fossil record, and competing hypotheses of relationships are discussed. Details of the divergence times are presented for each node in the timetree, and primary literature references are included. The book is complemented by an online database(www.timetree.net) which allows researchers to both deposit and retrieve data.

Book Description
What teeth can tell us about human evolution, development, and behavior. Our teeth have intriguing stories to tell. These sophisticated time machines record growth, diet, and evolutionary history as clearly as tree rings map a redwood's lifespan. Each day of childhood is etched into tooth crowns and roots—capturing birth, nursing history, environmental clues, and illnesses. The study of ancient, fossilized teeth sheds light on how our ancestors grew up, how we evolved, and how prehistoric cultural transitions continue to affect humans today. In The Tales Teeth Tell, biological anthropologist Tanya Smith offers an engaging and surprising look at what teeth tell us about the evolution of primates—including our own uniqueness. Humans' impressive set of varied teeth provides a multipurpose toolkit honed by the diet choices of our mammalian ancestors. Fossil teeth, highly resilient because of their substantial mineral content, are all that is left of some long-extinct species. Smith explains how researchers employ painstaking techniques to coax microscopic secrets from these enigmatic remains. Counting tiny daily lines provides a way to estimate age that is more powerful than any other forensic technique. Dental plaque—so carefully removed by dental hygienists today—records our ancestors' behavior and health in the form of fossilized food particles and bacteria, including their DNA. Smith also traces the grisly origins of dentistry, reveals that the urge to pick one's teeth is not unique to humans, and illuminates the age-old pursuit of “dental art.” The book is generously illustrated with original photographs, many in color.

Book Description
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).

Book Description
Scientists have recently begun to question one of the pillars of modern thought--Charles Darwin's theory of evolution. Certainly evolution occurs; but if it is a slow, continuous process by which one species gradually modifies itself into a new one, as Darwin believed, why are there so many missing links in the fossil records? Two eminent scientists, Niles Eldredge and Stephen Jay Gould, startled the world by challenging Darwin's cherished beliefs proposing instead that once a species has evolved it rarely undergoes change, and that the evolution of new species occurs only periodically, in relatively rapid spurts. In Time Frames Niles Eldredge explains how his own work with trilobite fossils led him to this unexpected conclusion, and describes the fascinating development of the new theory of punctuated equilibria. Originally published in 1989. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

"Beautifully written, eloquently reasoned…Mr. Buonomano takes us off and running on an edifying scientific journey." —Carol Tavris, Wall Street Journal In Your Brain Is a Time Machine, leading neuroscientist Dean Buonomano embarks on an "immensely engaging" exploration of how time works inside the brain (Barbara Kiser, Nature). The human brain, he argues, is a complex system that not only tells time, but creates it; it constructs our sense of chronological movement and enables "mental time travel"—simulations of future and past events. These functions are essential not only to our daily lives but to the evolution of the human race: without the ability to anticipate the future, mankind would never have crafted tools or invented agriculture. This virtuosic work of popular science will lead you to a revelation as strange as it is true: your brain is, at its core, a time machine.
