By focusing on the cellular mechanisms that underlie ontogeny, phylogeny and regeneration of complex physiologic traits, Evolution, the Logic of Biology demonstrates the use of homeostasis, the fundamental principle of physiology and medicine, as the unifying mechanism for evolution as all of biology. The homeostasis principle can be used to understand how environmental stressors have affected physiologic mechanisms to generate condition-specific novelty through cellular mechanisms.

Evolution, the Logic of Biology allows the reader to understand the vertebrate life-cycle as an intergenerational continuum in support of effective, on-going environmental adaptation. By understanding the principles of physiology from their fundamental unicellular origins, culminating in modern-day metazoans, the reader as student, researcher or practitioner will be encouraged to think in terms of the prevention of disease, rather than in the treatment of disease as the eradication of symptoms.

By tracing the ontogeny and phylogeny of this and other phenotypic homologies, one can perceive and understand how complex physiologic traits have mechanistically evolved from their simpler ancestral and developmental origins as cellular structures and functions, providing a logic of biology for the first time.

Evolution, the Logic of Biology will be an invaluable resource for graduate students and researchers studying evolutionary development, medicine and biology, anthropology, comparative and developmental biology, genetics and genomics, and physiology.

Why We Sleep: Unlocking the Power of Sleep and Dreams [EPUB]
Why We Sleep: Unlocking the Power of Sleep and Dreams by Matthew Walker

The first sleep book by a leading scientific expert—Professor Matthew Walker, Director of UC Berkeley’s Sleep and Neuroimaging Lab—reveals his groundbreaking exploration of sleep, explaining how we can harness its transformative power to change our lives for the better.

Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don't sleep. Compared to the other basic drives in life—eating, drinking, and reproducing—the purpose of sleep remained elusive.

An explosion of scientific discoveries in the last twenty years has shed new light on this fundamental aspect of our lives. Now, preeminent neuroscientist and sleep expert Matthew Walker gives us a new understanding of the vital importance of sleep and dreaming. Within the brain, sleep enriches our ability to learn, memorize, and make logical decisions. It recalibrates our emotions, restocks our immune system, fine-tunes our metabolism, and regulates our appetite. Dreaming mollifies painful memories and creates a virtual reality space in which the brain melds past and present knowledge to inspire creativity.

Walker answers important questions about sleep: how do caffeine and alcohol affect sleep? What really happens during REM sleep? Why do our sleep patterns change across a lifetime? How do common sleep aids affect us and can they do long-term damage? Charting cutting-edge scientific breakthroughs, and synthesizing decades of research and clinical practice, Walker explains how we can harness sleep to improve learning, mood, and energy levels; regulate hormones; prevent cancer, Alzheimer’s, and diabetes; slow the effects of aging; increase longevity; enhance the education and lifespan of our children, and boost the efficiency, success, and productivity of our businesses. Clear-eyed, fascinating, and accessible, Why We Sleep is a crucial and illuminating book.

Brief History of Everyone Who Ever Lived: The Human Story Retold Through Our Genes [EPUB]

A Brief History of Everyone Who Ever Lived: The Human Story Retold Through Our Genes by Adam Rutherford

In our unique genomes, every one of us carries the story of our species—births, deaths, disease, war, famine, migration, and a lot of sex.

But those stories have always been locked away—until now.

Who are our ancestors? Where did they come from? Geneticists have suddenly become historians, and the hard evidence in our DNA has blown the lid off what we thought we knew. Acclaimed science writer Adam Rutherford explains exactly how genomics is completely rewriting the human story—from 100,000 years ago to the present.

A Brief History of Everyone Who Ever Lived will upend your thinking on Neanderthals, evolution, royalty, race, and even redheads. (For example, we now know that at least four human species once roamed the earth.) Plus, here is the remarkable, controversial story of how our genes made their way to the Americas—one that’s still being written, as ever more of us have our DNA sequenced.

Rutherford closes with “A Short Introduction to the Future of Humankind,” filled with provocative questions that we’re on the cusp of answering: Are we still in the grasp of natural selection? Are we evolving for better or worse? And . . . where do we go from here?
