The genetic code appeared on Earth with the first cells. The codes of cultural evolution arrived almost four billion years later. These are the only codes that are recognized by modern biology. In this book, however, Marcello Barbieri explains that there are many more organic codes in nature, and their appearance not only took place throughout the history of life but marked the major steps of that history. A code establishes a correspondence between two independent 'worlds', and the codemaker is a third party between those 'worlds'. Therefore the cell can be thought of as a trinity of genotype, phenotype and ribotype. The ancestral ribotypes were the agents which gave rise to the first cells. The book goes on to explain how organic codes and organic memories can be used to shed new light on the problems encountered in cell signalling, epigenesis, embryonic development, and the evolution of language.

Building on a range of disciplines – from biology and anthropology to philosophy and linguistics – this book draws on the expertise of leading names in the study of organic, mental and cultural codes brought together by the emerging discipline of biosemiotics. The volume represents the first multi-authored attempt to deal with the range of codes relevant to life, and to reveal the ubiquitous role of coding mechanisms in both organic and mental evolution.

This book is the study of all codes of life with the standard methods of science. The genetic code and the codes of culture have been known for a long time and represent the historical foundation of this book. What is really new in this field is the study of all codes that came after the genetic code and before the codes of culture. The existence of these organic codes, however, is not only a major experimental fact. It is one of those facts that have extraordinary theoretical implications. The first is that most events of macroevolution were associated with the origin of new organic codes, and this gives us a completely new reconstruction of the history of life. The second implication is that codes involve meaning and we need therefore to introduce in biology not only the concept of information but also the concept of biological meaning. The third theoretical implication comes from the fact that the organic codes have been highly conserved in evolution, which means that they are the greatest invariants of life. The study of the organic codes, in short, is bringing to light new mechanisms that have operated in the history of life and new fundamental concepts in biology.

"Outstanding . . . a wide-ranging invitation to think through the moral ramifications of our eating habits." —The New Yorker One of the New York Times Book Review's Ten Best Books of the Year and Winner of the James Beard Award Author of This is Your Mind on Plants, How to Change Your Mind and the #1 New York Times Bestseller In Defense of Food and Food Rules What should we have for dinner? Ten years ago, Michael Pollan confronted us with this seemingly simple question and, with The Omnivore’s Dilemma, his brilliant and eye-opening exploration of our food choices, demonstrated that how we answer it today may determine not only our health but our survival as a species. In the years since, Pollan’s revolutionary examination has changed the way Americans think about food. Bringing wide attention to the little-known but vitally important dimensions of food and agriculture in America, Pollan launched a national conversation about what we eat and the profound consequences that even the simplest everyday food choices have on both ourselves and the natural world. Ten years later, The Omnivore’s Dilemma continues to transform the way Americans think about the politics, perils, and pleasures of eating.
