"This book is necessary reading for anyone working in sleep medicine. The reader will understand better why today, despite the abundant research reported in this book, we are far from understanding the entire function of sleep in humans. Yet at the same time, a good understanding can be gained about the evolutionary threads that can be perceived through phylogenetic analyses. We can use investigations of many different models to improve our knowledge of both animal and human sleep, and design protocols to pursue our quest to understand one of our vital functions.

This edited volume consists of a collection of essays from experts on the phylogeny, biology, and expression of sleep states in a broad range of animal species, from insects to mammals. An introductory chapter summarizes the history of the study of the evolutionary origins of sleep and basic concepts in sleep science, and a concluding set of chapters is devoted to synthesizing patterns documented in the previous chapters.
