This book review evaluates Derek A. Roff's "Life History Evolution," which integrates life history theory with empirical research. The author provides a comprehensive framework for analyzing life history traits, covering quantitative and population genetics, fitness measures, and trade-offs. Roff discusses evolution in various environmental contexts, including constant, stochastic, and predictable environments. The book is praised for its clear and accessible presentation of theory, linking it to empirical studies. However, the reviewer notes that the book's long chapters can make it challenging to find specific topics, and suggests expanding on the relationship between intrinsic rate of increase and matrix formulations. Overall, the book is highly recommended for its synthesis of theory and literature, and its identification of future research topics.This book review evaluates Derek A.
