From the author of the acclaimed The Epigenetics Revolution (‘A book that would have had Darwin swooning’ – Guardian) comes another thrilling exploration of the cutting edge of human science. For decades after the structure of DNA was identified, scientists focused purely on genes, the regions of the genome that contain codes for the production of proteins. Other regions – 98% of the human genome – were dismissed as ‘junk’. But in recent years researchers have discovered that variations in this ‘junk’ DNA underlie many previously intractable diseases, and they can now generate new approaches to tackling them. Nessa Carey explores, for the first time for a general audience, the incredible story behind a controversy that has generated unusually vituperative public exchanges between scientists. She shows how junk DNA plays an important role in areas as diverse as genetic diseases, viral infections, sex determination in mammals, human biological complexity, disease treatments, even evolution itself – and reveals how we are only now truly unlocking its secrets, more than half a century after Crick and Watson won their Nobel prize for the discovery of the structure of DNA in 1962.

According to the modern version of Darwin's theory, DNA contains a program for embryo development that is passed down from generation to generation; the program is implemented by proteins encoded by the DNA, and accidental DNA mutations introduce changes in those proteins that natural selection then shapes into new species, organs and body plans. When scientists discovered forty years ago that about 98% of our DNA does not encode proteins, the non-protein-coding portion was labeled “junk” and attributed to molecular accidents that have accumulated in the course of evolution. Recent books by Richard Dawkins, Francis Collins and others have used this “junk DNA” as evidence for Darwinian evolution and evidence against intelligent design (since an intelligent designer would presumably not have filled our genome with so much garbage). But recent genome evidence shows that much of our non-protein-coding DNA performs essential biological functions. The Myth of Junk DNA is written for a general audience by biologist Jonathan Wells, author of Icons of Evolution. Citing some of the abundant evidence from recent genome projects, the book shows that “junk DNA” is not science, but myth.

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.

'An excellent, brisk guide to what is likely to happen as opposed to the fantastically remote.' - Los Angeles Review of Books In 2018 the world woke up to gene editing with a storm of controversy over twin girls born in China with genetic changes deliberately introduced by scientists - changes they will pass on to their own offspring. Genetic modification (GM) has been with us for 45 years now, but the new system known as CRISPR or gene editing can manipulate the genes of almost any organism with a degree of precision, ease and speed that we could only dream of ten years ago. But is it ethical to change the genetic material of organisms in a way that might be passed on to future generations? If a person is suffering from a lethal genetic disease, is it unethical to deny them this option? Who controls the application of this technology, when it makes 'biohacking' - perhaps of one's own genome - a real possibility? Nessa Carey's book is a thrilling and timely snapshot of a cutting-edge technology that will radically alter our futures and the way we prevent disease. 'A focused snapshot of a brave new world.' - Nature 'A brisk, accessible primer on the fast-moving field, a clear-eyed look at a technology that is already driving major scientific advances - and raising complex ethical questions.' - Emily Anthes, Undark

As the Human Genome Project completed its mapping of the entire human genome, hopes ran high that we would rapidly be able to use our knowledge of human genes to tackle many inherited diseases, and understand what makes us unique among animals. But things didn't turn out that way ... but the emerging picture is if anything far more exciting. Parrington gives an outline of the deeper genome, involving layers of regulatory elements controlling and coordinating the switching on and off of genes; the impact of its 3D geometry; the discovery of a variety of new RNAs playing critical roles; the epigenetic changes influenced by the environment and life experiences that can make identical twins different and be passed on to the next generation; and the clues coming out of comparisons with the genomes of Neanderthals as well as that of chimps about the development of our species.

Science need not be dull and bogged down by jargon, as Richard Dawkins proves in this entertaining look at evolution. The themes he takes up are the concepts of altruistic and selfish behaviour; the genetical definition of selfish interest; the evolution of aggressive behaviour; kinshiptheory; sex ratio theory; reciprocal altruism; deceit; and the natural selection of sex differences. 'Should be read, can be read by almost anyone. It describes with great skill a new face of the theory of evolution.' W.D. Hamilton, Science

98% of our DNA is considered by mainstream science to be "genetic gibberish, junk."This very title pokes fun at that notion because deep inside, we know the truth! Open the pages of this book and unlock the hidden secrets.....Our DNA contains everything we needed to know to survive for the past millennia. 5 senses? How about 128 Sensory Channels: perceptions that helped Stone Age mankind survive and could enhance our world today. Auras, electromagnetic fields, radiational and gravitational forces, bio-energetics, sounds, colors, energy centers, endocrine senses, Sun, magnetic reference for people and places, mathematics, God, language, spirits, solar system, and many more. All the healing knowledge we humans need to know about has been embedded and stored in the crystals of our own DNA. Crystals transmit information to us, about survival, about our past and about healing. We have 'forgotten' much - we just need to access, to listen, and be open to the possibilities. So take a step back in time and discover what has been stored in the genes since the earliest moments of creation. Your journey to self awareness starts here. "The double helix presented as never before! Scogna teaches us about life at the crystal level as no research scientist would think to describe it." -Mary Habeeb "The Macro-Micro aspects of the cosmos and humankind. Just like Tesla, some spirits arrive well before their time. Joe Scogna pulled back the veil of time to show us a new understanding of ourselves and instill the courage to embrace what is needed and to heal in these challenging times." -Bruce L. Erickson, Mother Earth Media "Learn about the 128 sense perceptions-not just five!-and how we are each imbued with crystalline structures in our RNA/DNA which are constantly evolving and changing to insure survival, towards our betterment and optimal health. Scogna purported this long before anyone had a clue." -Nancy B. Porter, DN, LISW "Joe Scogna's explanation of how life forms are altered by a natural process supports an evolutionist's position, but the concept of a genetic planning mechanism suggests an intelligent designer at work. Who designed that mechanism?" -Linda Schwank

What’s in Your Genome? describes the functional regions of the human genome, the evidence that 90% of it is junk DNA, and the reasons this evidence has not been widely accepted by the popular press and much of the scientific community. The human genome contains about 25,000 protein-coding and noncoding genes and many other functional elements, such as origins of replication, regulatory elements, and centromeres. Functional elements occupy only about 10 percent of the more than three billion base pairs in the human genome. Much of the rest is composed of ancient fragments of broken genes, transposons, and viruses. Almost all of this is thought to be junk DNA, based on evidence that dates back fifty years. This conclusion is controversial. What’s in Your Genome? describes the arguments on both sides of the debate and attempts to explain the reasoning behind those different points of view. The book corrects a number of false narratives that have arisen in recent years and examines how they have affected the debate over junk DNA. In addition, Laurence A. Moran focuses on scientific misconceptions and misinformation and on how the junk DNA controversy has been incorrectly portrayed in both the scientific literature and the popular press. Tracing the earliest indications of junk DNA back to the 1960s, the book explains the success of nearly neutral theory and the importance of random genetic drift, which gave rise to the view that evolution produces sloppy genomes full of junk DNA. What’s in Your Genome? aims to offer the most accurate and current account of the human genome.

A thought-provoking exploration of deleterious mutations in the human genome and their effects on human health and wellbeing Despite all of the elaborate mechanisms that a cell employs to handle its DNA with the utmost care, a newborn human carries about 100 new mutations, originated in their parents, about 10 of which are deleterious. A mutation replacing just one of the more than three billion nucleotides in the human genome may lead to synthesis of a dysfunctional protein, and this can be inconsistent with life or cause a tragic disease. Several percent of even young people suffer from diseases that are caused, exclusively or primarily, by pre ]existing and new mutations in their genomes, including both a wide variety of genetically simple Mendelian diseases and diverse complex diseases such as birth anomalies, diabetes, and schizophrenia. Milder, but still substantial, negative effects of mutations are even more pervasive. As of now, we possess no means of reducing the rate at which mutations appear spontaneously. However, the recent flood of genomic data made possible by next-generation methods of DNA sequencing, enabled scientists to explore the impacts of deleterious mutations on humans with previously unattainable precision and begin to develop approaches to managing them. Written by a leading researcher in the field of evolutionary genetics, Crumbling Genome reviews the current state of knowledge about deleterious mutations and their effects on humans for those in the biological sciences and medicine, as well as for readers with only a general scientific literacy and an interest in human genetics. Provides an extensive introduction to the fundamentals of evolutionary genetics with an emphasis on mutation and selection Discusses the effects of pre-existing and new mutations on human genotypes and phenotypes Provides a comprehensive review of the current state of knowledge in the field and considers crucial unsolved problems Explores key ethical, scientific, and social issues likely to become relevant in the near future as the modification of human germline genotypes becomes technically feasible Crumbling Genome is must-reading for students and professionals in human genetics, genomics, bioinformatics, evolutionary biology, and biological anthropology. It is certain to have great appeal among all those with an interest in the links between genetics and evolution and how they are likely to influence the future of human health, medicine, and society.
