Acclaimed biologist Lewis Wolpert eloquently narrates the basics of human life through the lens of its smallest component: the cell. Everything about our existence— imagination and reproduction, birth and death—is governed by our cells. They are the basis of all life in the universe, from the tiniest of bacteria to the most complex of animals. Genes in developing embryos determine the makeup of individuals, and the rapid firing between nerve cells creates the spirit of who we are. When we age, our cells cannot repair the damage they have undergone; when we get ill, it is because cells are so damaged they stop working and die. In the tradition of Lewis Thomas’s science classic The Lives of a Cell, Wolpert, an internationally acclaimed embryologist, draws on the recent discoveries of genetics to demonstrate how human life derives from a single cell and then grows into a body: an incredibly complex society made up of billions of cells. Wolpert sensitively examines the science behind often controversial research topics that are much discussed by rarely understood—stem cell research, cloning, DNA, and mutating cancer cells—all the while illuminating how the intricacies of cellular behavior bear directly on human behavior. Wolpert isn’t afraid to tackle the tough questions, including how and why single cells evolved into complex organisms and, first and foremost, what gave rise to the original cell, the origin of all life. Lively and passionate, How We Live and Why We Die is both an accessible guide to understanding the human body and a deeply reverent meditation on life itself.

Why are there two sexes? How different are they and why? Why can't a woman be more like a man? Or should the question be: why can't a man be more like a woman? Controversy rages around sex and gender, but just what are the differences and how are they determined? Lewis Wolpert, distinguished scientist, broadcaster and author, has tackled depression, religion and old age from a developmental biologist's perspective. Now he enters the gender debate, starting with his argument that men are fundamentally modified females - if the genes present at fertilisation did not do their job properly, we would all be women - and journeying through MRI techniques, the nature of sexual attraction, 'neurosexism' and whether men are really better at maths. With fresh and persuasive research and with his customary intelligence and curiosity, Lewis Wolpert sets out to make his mark on this controversial topic - and makes some surprising discoveries along the way.

All living things on Earth are composed of cells. A cell is the simplest unit of a self-contained living organism, and the vast majority of life on Earth consists of single-celled microbes, mostly bacteria. These consist of a simple 'prokaryotic' cell, with no nucleus. The bodies of more complex plants and animals consist of billions of 'eukaryotic' cells, of varying kinds, adapted to fill different roles - red blood cells, muscle cells, branched neurons. Each cell is an astonishingly complex chemical factory, the activities of which we have only begun to unravel in the past fifty years or so through modern techniques of microscopy, biochemistry, and molecular biology. In this Very Short Introduction, Terence Allen and Graham Cowling describe the nature of cells - their basic structure, their varying forms, their division, their differentiation from initially highly flexible stem cells, their signalling, and programmed death. Cells are the basic constituent of life, and understanding cells and how they work is central to all biology and medicine.
