Overview

From Darwin onward, it has been second nature for evolutionary biologists to think comparatively because comparisons establish the generality of evolutionary phenomena. Do large genomes slow down development? What lifestyles select for large brains? Are extinction rates related to body size? These are all questions for the comparative method, and this book is about how such questions can be answered. The first chapter elaborates on suitable questions for the comparative approach and shows how it complements other approaches to problem-solving in evolution such as optimality theory, population genetic models, and experimentation. The second chapter identifies the biological causes of similarity among closely related species for almost any observed character. The third chapter discusses methods for reconstructing phylogenetic trees and ancestral character states, emphasizing the importance on the underlying assumptions about evolutionary processes in arriving at the results. The fourth chapter sets out to develop statistical tests that will determine whether different characters that exist in discrete states (such as warning colouration and distastefulness in caterpillars) show evidence for correlated evolution. Chapter 5 turns to comparative analyses of continuously varying characters. Chapter 6 looks at allometry to exemplify application of the themes and methods earlier, while the last chapter looks to future development of the comparative approach in both molecular and organism biology.
