Lamarck's Revenge


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.




The Epigenetics Revolution


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.

Evolutionary Genetics


Book Description

Evolutionary genetics is the study of how genetic variation leads to evolutionary change. With the recent explosion in the availability of whole genome sequence data, vast quantities of genetic data are being generated at an ever-increasing pace with the result that programming has become an essential tool for researchers. Most importantly, a thorough understanding of evolutionary principles is essential for making sense of this genetic data. This up-to-date textbook covers all the major components of modern evolutionary genetics, carefully explaining fundamental processes such as mutation, natural selection, genetic drift, and speciation, together with their consequences. The book 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. Furthermore, at the end of each chapter, study questions are provided to motivate the reader to think and reflect on the concepts introduced. Practical experience is essential when it comes to developing an understanding of how to use genetic and genomic data to analyze and address interesting questions in the life sciences and how to 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 the analysis of evolutionary genetic data. The R environment stands out as an ideal all-purpose, open 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 introduce readers to the plethora of molecular and analytical methods that have only recently become available.




30-Second Genetics


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!




Modern Prometheus


Book Description

This book tells the dramatic story of Crispr and the potential impact of this gene-editing technology.




Environmental DNA


Book Description

Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water, feces, or air) without the prior isolation of any target organism. The analysis of environmental DNA has the potential of providing high-throughput information on taxa and functional genes in a given environment, and is easily amenable to the study of both aquatic and terrestrial ecosystems. It can provide an understanding of past or present biological communities as well as their trophic relationships, and can thus offer useful insights into ecosystem functioning. There is now a rapidly-growing interest amongst biologists in applying analysis of environmental DNA to their own research. However, good practices and protocols dealing with environmental DNA are currently widely dispersed across numerous papers, with many of them presenting only preliminary results and using a diversity of methods. In this context, the principal objective of this practical handbook is to provide biologists (both students and researchers) with the scientific background necessary to assist with the understanding and implementation of best practices and analyses based on environmental DNA.




Coming To Life


Book Description

Christiane Nusslein-Volhard, winner of The Nobel Prize in Medicine, gives a concise and illustrative overview of genetics, evolution, and cellular processes as well as a discussing of current ethical issues in human biology. Coming to Life is a remarkable journey through developmental biology that reveals miraculous processes in the microscopic world of cells. Through an accounting of groundbreaking discoveries, Christiane Nusslein-Volhard tells us many answers to historical and contemporary questions in science. For example, she brings us the newest knowledge about embryonic forms, explains the genetic mechanisms that influence adult development of all animals, and shares insights into the ethical standards society moist uphold in the face of new scientific discoveries. As the author leads us from laboratory research to its applications in human beings, we also come to understand why children look like their parents, how an embryonic cell knows to become an eye rather than an eyelash, and other incredible influences hat result in variety in life. Complete with her own hand-drawn illustrations, Coming to Life gives a rare opportunity to understand a Nobel Prize-winner's passion for science in concise, understandable language. 55 b/w illustrations.




Mendel's Legacy


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.
