The past 25 years has seen the emergence of a wealth of data suggesting that novel biological functions of known proteins play important roles in biology and medicine. This ability of proteins to exhibit more than one unique biological activity is known as protein moonlighting. Moonlighting proteins can exhibit novel biological functions, thus extending the function of the proteome, and are also implicated in the pathology of a growing number of idiopathic and infectious diseases.

This book summarizes the knowledge in the field of methods to identify signatures of natural selection. A number of mathematical models and methods have been designed to identify the fingerprints of natural selection on genes and genomes. Such methods are provided in a simple and direct way so that students of different disciplines can navigate through molecular fitness landscapes using complex methods with a basic knowledge on bioinformatics.

A collection of the main methods to detect selection in protein-coding genes and amino acid sequences is given at different levels of...
