Originally published in 1985, The Semantic Theory of Evolution addresses the notion that life is not shaped by the single law of natural selection, but instead by a plurality of laws that resemble grammatical rules in language. This remarkable work presents a semantic theory centering on the concept of the ribotype. Supported by both sound facts and logical arguments, this analysis reaches beyond the established cadre of biological thought to unravel many of life’s mysteries and paradoxes, including the origin of the cell and the nucleus and the evolution of ribosomes.

Combining research approaches from biology, philosophy and linguistics, the field of Biosemiotics proposes that animals, plants and single cells all engage in semiosis – the conversion of objective signals into conventional signs. This has important implications and applications for issues ranging from natural selection to animal behavior and human psychology, leaving biosemiotics at the cutting edge of the research on the fundamentals of life.

Drawing on an international expertise, the book details the history and study of biosemiotics, and provides a state-of-the-art summary of the current work in this new field. And, with relevance to a wide range of disciplines – from linguistics and semiotics to evolutionary phenomena and the philosophy of biology – the book provides an important text for both students and established researchers, while marking a vital step in the evolution of a new biological paradigm.

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 book’s 18 chapters present a range of experimental evidence which suggests that the genetic code was only the first in a long series of organic codes, and that it has been the appearance of new codes – organic, mental and cultural – that paved the way for the major transitions in the history of life.

While the existence of many organic codes has been proposed since the 1980s, this 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 creates the conditions for a synthesis of biology and linguistics that finally overcomes the old divide between nature and culture.

The book will appeal to all those interested in the origins and evolution of life, including biologists (from molecular and cellular biologists to evolutionary and developmental biologists), ecologists, anthropologists, psychologists, philosophers of science, linguists, and researchers interested in the history of science, the origins of life, artificial life and intelligence, and information theory and communication technology.

This text builds upon the over 1500 papers published in peer-reviewed journals revealing that there are more than 200 biological codes in living systems.  The author claims this experimental fact is bound to change biology forever. This book shows how this very discovery reveals that coding is a new mechanism of life, just as the discovery of electromagnetism revealed the existence of a new physical force in the universe. The existence of many biological codes, furthermore, Barbieri argues, is one of those experimental facts that have extraordinary theoretical consequences. It implies that coding is not only a mechanism that constantly operates in all living systems, but also a mechanism of evolution, more precisely a mechanism that gave origin to the absolute novelties of the history of life. This amounts to saying that evolution took place by two distinct mechanisms, by natural selection and by natural conventions, two mechanisms that are fundamentally different because natural selection is the result of copying and deals with information whereas natural conventions are the result of coding and deal with meaning.  This volume appeals to students and researchers working in the fields of semiotics, philosophy, biology and mathematics.

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.
