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.

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.

Now in paperback for the first time since its original publication, the material gathered here is perfect for anyone who needs a detailed and accessible introduction to the important semantic theories. Designed for a wide audience, it will be of great value to linguists, cognitive scientists, philosophers, and computer scientists working on natural language. The book covers theories of lexical semantics, cognitively oriented approaches to semantics, compositional theories of sentence semantics, and discourse semantics. This clear, elegant explanation of the key theories in semantics research is essential reading for anyone working in the area.
