Book Description
A riveting explanation of epigenetics, offering startling insights into our inheritable traits. In the 1700s, Jean-Baptiste Lamarck first described epigenetics to explain the inheritance of acquired characteristics; however, his theory was supplanted in the 1800s by Darwin's theory of evolution by natural selection through heritable genetic mutations. But natural selection could not adequately explain how rapidly species re-diversified and repopulated after mass extinctions. Now advances in the study of DNA and RNA have resurrected epigenetics, which can create radical physical and physiological changes in subsequent generations by the simple addition of a single small molecule, thus passing along a propensity for molecules to attach in the same places in the next generation. Epigenetics is a complex process, but paleontologist and astrobiologist Peter Ward breaks it down for general readers, using the epigenetic paradigm to reexamine how the history of our species-from deep time to the outbreak of the Black Plague and into the present-has left its mark on our physiology, behavior, and intelligence. Most alarming are chapters about epigenetic changes we are undergoing now triggered by toxins, environmental pollutants, famine, poor nutrition, and overexposure to violence. Lamarck's Revenge is an eye-opening and provocative exploration of how traits are inherited, and how outside influences drive what we pass along to our progeny.

Book Description
Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the twenty-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics. Nessa Carey, a leading epigenetics researcher, connects the field's arguments to such diverse phenomena as how ants and queen bees control their colonies; why tortoiseshell cats are always female; why some plants need cold weather before they can flower; and how our bodies age and develop disease. Reaching beyond biology, epigenetics now informs work on drug addiction, the long-term effects of famine, and the physical and psychological consequences of childhood trauma. Carey concludes with a discussion of the future directions for this research and its ability to improve human health and well-being.

Book Description
This whistlestop guide teaches you everything you need to know about the fascinating science of genetics! Genetics is the study of heredity, and reveals how the characteristics of living organisms are determined by the genes passed down the generations. In humans, it can determine how we think,who we are, and how long we live. The human genome was mapped in 2003, and this enhanced ability to study our genes is transforming medicine, from CRISPR, the gene editing technology that allows us to alter the course of hereditary disease, to using genetics to identify the types of bacteria that populate our bodies. Stripping the subject to its bare necessities,30-Second Genetics charts the most extraordinary discoveries, from the fundamentals of cell biology to the almost unbelievable advances in DNA sequencing and stem cell technology. Each subject, concept or term is explored in a mere 30 seconds, 300 words, and one image, making this the perfect book to understand the field of genetics at lightening speed! Authors (and identical twin brothers) Jonathan and Matthew Weitzman are both expert professors in the field, and they write with clarity, exploring these complicated terms in easy to understand language. From advances in stem cell therapy to animal cloning, genetically modified crops and genetically tailored treatments, the Weitzman brothers demystify this essential science which is shaping our future, today!

Book Description
With recent technological advances, vast quantities of genetic and genomic data are being generated at an ever-increasing pace. The explosion in access to data has transformed the field of evolutionary genetics. A thorough understanding of evolutionary principles is essential for making sense of this, but new skill sets are also needed to handle and analyze big data. This contemporary textbook covers all the major components of modern evolutionary genetics, carefully explaining fundamental processes such as mutation, natural selection, genetic drift, and speciation. It also draws on a rich literature of exciting and inspiring examples to demonstrate the diversity of evolutionary research, including an emphasis on how evolution and selection has shaped our own species. Practical experience is essential for developing an understanding of how to use genetic and genomic data to analyze and interpret results in meaningful ways. In addition to the main text, a series of online tutorials using the R language serves as an introduction to programming, statistics, and analysis. Indeed the R environment stands out as an ideal all-purpose source platform to handle and analyze such data. The book and its online materials take full advantage of the authors' own experience in working in a post-genomic revolution world, and introduces readers to the plethora of molecular and analytical methods that have only recently become available. Evolutionary Genetics is an advanced but accessible textbook aimed principally at students of various levels (from undergraduate to postgraduate) but also for researchers looking for an updated introduction to modern evolutionary biology and genetics.

Book Description
This latest book by Elof Carlson (The Unfit) is a first history of classical genetics, the era in which the chromosome theory of heredity was proposed and developed. Highly illustrated and based heavily on early 20th century original sources, the book traces the roots of genetics in breeding analysis and studies of cytology, evolution, and reproductive biology that began in Europe but were synthesized in the United States through new Ph.D. programs and expanded academic funding. Carlson argues that, influenced largely by new technologies and instrumentation, the life sciences progressed though incremental change rather than paradigm shifts, and he describes how molecular biology emerged from the key ideas and model systems of classical genetics. Readable and original, this narrative will interest historians and science educators as well as today's practitioners of genetics.

Book Description
Bonduriansky and Day challenge the premise that genes alone mediate the transmission of biological information across generations and provide the raw material for natural selection. They explore the latest research showing that what happens during our lifetimes--and even our parents' and grandparents' lifetimes--can influence the features of our descendants. Based on this evidence, Bonduriansky and Day develop an extended concept of heredity that upends ideas about how traits can and cannot be transmitted across generations, opening the door to a new understanding of inheritance, evolution, and even human health. --Adapted from publisher description.

Book Description
The triumphant memoir of the man behind one of the greatest feats in scientific history Of all the scientific achievements of the past century, perhaps none can match the deciphering of the human genetic code, both for its technical brilliance and for its implications for our future. In A Life Decoded, J. Craig Venter traces his rise from an uninspired student to one of the most fascinating and controversial figures in science today. Here, Venter relates the unparalleled drama of the quest to decode the human genome?a goal he predicted he could achieve years earlier and more cheaply than the government-sponsored Human Genome Project, and one that he fulfilled in 2001. A thrilling story of detection, A Life Decoded is also a revealing, and often troubling, look at how science is practiced today.

Book Description
What are the genomic signatures of adaptations in DNA? How often does natural selection dictate changes to DNA? How does the ebb and flow in the abundance of individuals over time get marked onto chromosomes to record genetic history? Molecular population genetics seeks to answer such questions by explaining genetic variation and molecular evolution from micro-evolutionary principles. It provides a way to learn about how evolution works and how it shapes species by incorporating molecular details of DNA as the heritable material. It enables us to understand the logic of how mutations originate, change in abundance in populations, and become fixed as DNA sequence divergence between species. With the revolutionary advances in genomic data acquisition, understanding molecular population genetics is now a fundamental requirement for today's life scientists. These concepts apply in analysis of personal genomics, genome-wide association studies, landscape and conservation genetics, forensics, molecular anthropology, and selection scans. This book introduces, in an accessible way, the bare essentials of the theory and practice of molecular population genetics.
