Description de l’éditeur
How do we move, think and remember? Why do we get ill, age and die? Distinguished biologist Lewis Wolpert explains how cells provide the answers to the fundamental questions about our lives.
Cells are the basis of all life in the universe. Our bodies are made up of billions of them: an incredibly complex society that governs everything, from movement to memory and imagination. When we age, it is because our cells slow down; when we get ill, it is because our cells mutate or stop working.
In How We Live and Why We Die, Wolpert provides a clear explanation of the science that underpins our lives. He explains how our bodies function and how we derive from a single cell - the egg. He examines the science behind the topics that are much discussed but rarely understood - stem-cell research, cloning, DNA - and explains how all life evolved from just one cell. Lively and passionate, How We Live and Why We Die is an accessible guide to understanding the human body and, essentially, life itself.
PUBLISHERS WEEKLY
Wolpert, professor emeritus of biology at University College London (Six Impossible Things Before Breakfast), conceives bodies as complex societies of cells, with each individual cell and cell type fulfilling a very specific role. As Wolpert explains, cells are incredibly complicated, representing evolution in action. Indeed, Wolpert asserts, "However clever one thinks cells are, they almost always turn out to exceed one's expectations." He provides basic biological information about cell structure, genetics and reproduction, and then discusses the roles cells play in disease, aging, death, reproduction, memory, emotion and much more. In focusing on the process of human development, he marvels at how a single cell, a fertilized egg, can grow into a complex organism. Along the way, Wolpert lightly touches on some hot-button topics like the ethics of stem cell research; when a developing fetus might be considered human; and the ethics of cloning. His range is so great that he has little time to delve beneath the surface of any of the subjects he raises, making this a cursory introduction for the novice in basic cell biology and its implications.
