Every character of a living being has its function: the teeth are there to chew, the lungs to breathe, the eyes to see, etc. But what is the function of aging, if there even is one?If it is true that the living being is modelled by natural selection, what are the evolutionary needs that bring about limited longevity or variable longevity according to the species? Why does a mouse live less than two years, a tortoise many tens of years and Pinus Aristata not seem to age at all? Are these differences casual or is evolution somehow at the origin of it all, as A. Weismann hypothesized back in the last century?The results are beyond all expectations: it is possible to provide an explanation for the "why of senescence in evolutionary terms.Another important topic is the meaning of disease phenomenon in the context of evolutionary theory. Illness is a set of phenomena that is perfectly anticipated and rationally classifiable by evolutionary theory.This book, printed in Italian in 1983, broached these and other questions with a rigorous evolutionary approach, using mathematical models in its arguments for the graphic expression and the confirmation of the models.

A revolutionary examination of why we age, what it means for our health, and how we just might be able to fight it. In Cracking the Aging Code, theoretical biologist Josh Mitteldorf and award-winning writer and ecological philosopher Dorion Sagan reveal that evolution and aging are even more complex and breathtaking than we originally thought. Using meticulous multidisciplinary science, as well as reviewing the history of our understanding about evolution, this book makes the case that aging is not something that “just happens,” nor is it the result of wear and tear or a genetic inevitability. Rather, aging has a fascinating evolutionary purpose: to stabilize populations and ecosystems, which are ever-threatened by cyclic swings that can lead to extinction. When a population grows too fast it can put itself at risk of a wholesale wipeout. Aging has evolved to help us adjust our growth in a sustainable fashion as well as prevent an ecological crisis from starvation, predation, pollution, or infection. This dynamic new understanding of aging is provocative, entertaining, and pioneering, and will challenge the way we understand aging, death, and just what makes us human.

While the health of aging men has been a focus of biomedical research for years, evolutionary biology has not been part of the conversation—until now. How Men Age is the first book to explore how natural selection has shaped male aging, how evolutionary theory can inform our understanding of male health and well-being, and how older men may have contributed to the evolution of some of the very traits that make us human. In this informative and entertaining book, renowned biological anthropologist Richard Bribiescas looks at all aspects of male aging through an evolutionary lens. He describes how the challenges males faced in their evolutionary past influenced how they age today, and shows how this unique evolutionary history helps explain common aspects of male aging such as prostate disease, loss of muscle mass, changes in testosterone levels, increases in fat, erectile dysfunction, baldness, and shorter life spans than women. Bribiescas reveals how many of the physical and behavioral changes that we negatively associate with male aging may have actually facilitated the emergence of positive traits that have helped make humans so successful as a species, including parenting, long life spans, and high fertility. Popular science at its most compelling, How Men Age provides new perspectives on the aging process in men and how we became human, and also explores future challenges for human evolution—and the important role older men might play in them.

Believe it or not, our DNA is almost exactly the same as that of our ancestors. While scientific advances in agriculture, medicine, and technology have protected man, to some degree, from dangers such as starvation, illness, and exposure, the fact remains that our cave-dwelling cousins were considerably healthier than we are. Our paleolithic ancestors did not suffer from heart disease, diabetes, high blood pressure, or obesity. In fact, a good deal of what we view as normal aging is a modern condition that is more akin to disease than any natural state of growing older. Disease-free and strikingly fit, 72-year-old Arthur De Vany--grandfather of the "Paleo lifestyle movement--is living proof that it pays to live like a caveman. In The New Evolution Diet, De Vany offers you a roadmap back to better health. The plan is built on three principles: eat three meals a day made up of nonstarchy vegetables, fruits, and lean proteins skip meals occasionally to promote a low fasting blood insulin level exercise less, not more, in shorter, high-intensity bursts By cutting out modern foods--including carbohydrates, dairy, and all processed foods--anyone can lose weight, gain muscle, and enjoy a longer, better life.

The pineal is regarded as an ontogenic and evolutionary point of departure for research on the causes of senescence, suppported by in vivo experimental evidence, such as pineal cross-transplantation. Among the findings reported here, that reinforce the concept of the central clock, is the unique ability of melatonin to keep dangerous hydroxyl radicals under control. In addition, studies on the effect of caloric restriction and nutritional factors are building blocks in the understanding of how and why we age and develop cancer, together with other studies such as: the role of ubiquitous zinc and of extra-pineal melatonin; the disruption of biological rhythms; ultra-structure in brain diseases and dementia; the transacting factors as key regulatory proteins that mediate families of stress response genes; the aging antigen; the mother steroid DHEA during aging; the role of protein kinase C; the loss of D2 dopamine receptors during aging; brain amyloid formation; the role of cell cycles and cyclic AMP; the pineal peptides; and the decay of central neuro-endocrine-immune functions during aging.

This book considers the branch of heredity known as "epigenetics" and its implications for a variety of diseases in humans and animals. After background information on the growth in understanding genetics and the mechanisms of the epigenetic control of gene expression, the book moves into its main focus: the gathering body of evidence connecting genetics to a range of significant illnesses, including cancer, autism, Alzheimer's disease, diabetes and others. Areas of uncertainty are stressed as well as the scientific debate concerning the role of environmental factors. The final chapters discuss the implications for society. Extensive notes provide additional details and personal anecdotes.
