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.

Traditionally a scientific theory is viewed as based on universal laws of nature that serve as axioms for logical deduction. In analyzing the logical structure of evolutionary biology, Elisabeth Lloyd argues that the semantic account is more appropriate and powerful. This book will be of interest to biologists and philosophers alike.

Darwin’s nineteenth-century writings laid the foundations for modern studies of evolution, and theoretical developments in the mid-twentieth century fostered the Modern Synthesis. Since that time, a great deal of new biological knowledge has been generated, including details of the genetic code, lateral gene transfer, and developmental constraints. Our improved understanding of these and many other phenomena have been working their way into evolutionary theory, changing it and improving its correspondence with evolution in nature. And while the study of evolution is thriving both as a basic science to understand the world and in its applications in agriculture, medicine, and public health, the broad scope of evolution—operating across genes, whole organisms, clades, and ecosystems—presents a significant challenge for researchers seeking to integrate abundant new data and content into a general theory of evolution. This book gives us that framework and synthesis for the twenty-first century. The Theory of Evolution presents a series of chapters by experts seeking this integration by addressing the current state of affairs across numerous fields within evolutionary biology, ranging from biogeography to multilevel selection, speciation, and macroevolutionary theory. By presenting current syntheses of evolution’s theoretical foundations and their growth in light of new datasets and analyses, this collection will enhance future research and understanding.

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.

This volume provides a scientific justification for the optimal formula of social justice through a critical analysis of the basic principles of Marxism. While interest in Marxism is particularly prevalent in China today, the theory developed here concerning the origins and evolution of man will be of interest to everyone, and will help to contextualise questions of social justice within a scientific framework. By providing a new interpretation of Hegelian thought, alongside a synthesis of the thinking of Darwin and Marx, the book details a law of the development of society, using notable events from world history, particularly the collapse of the USSR, to verify it.
