Darwinian theory, with genes at its center, still frames our discussion of evolution. Yet now the picture within the frame-a portrait rendered in detail at the cellular and molecular level-contains the real stuff of today's big questions about living organisms. Genetics and molecular biology have revealed a new realm of complexity in life, with major implications for how we understand evolution.

Genetics and the Logic of Evolution provides a much-needed overview and analysis of general principles and patterns of evolution in light of contemporary biology. Taking a functional approach to explain how genes are used across the diverse range of species, the authors consider:

• Basic concepts and principles of biological complexity
• Alternative and supplemental principles to Darwinian theory
• Building blocks of life: how DNA, RNA, and genes work in single-cell and multi-cellular organisms
• Communication within an organism
• Detection and perception of the environment
• Evolutionary order and disorder and the sometimes fluid relationships between phenotypes and genotypes

Working outwards from the molecular level, Genetics and the Logic of Evolution moves its discourse towards a broader sense of life and how organisms live it. Written to be both scientifically rigorous and accessible to the layman, this treatment offers students and practitioners a refreshingly grand tour of the most important generalizations to emerge from recent biological research.
