The narrowing of the genomic regions controlling adaptations has employed mainly three different approaches termed forward genetics, reverse genetics and candidate gene (Stinchcombe & Hoekstra 2007 Nadeau & Jiggins 2010). This has and will continue to contribute to answering important questions about how evolution proceeds: Do adaptations arise gradually through many small mutations, via large leaps of major effect or both? Is the evolution of similar traits in different lineages the product of mutations in the same genes? Are particular kinds of adaptive mutations more likely than others, such as gene regulatory or protein-coding mutations? Here, we will focus on the methods used to address these questions. Consequently, much of modern research in evolution is devoted to identifying the genes shaping adaptive phenotypes (Hoekstra & Coyne 2007 Stern & Orgogozo 2009 Nadeau & Jiggins 2010 Jones et al. Until recently, addressing this question was methodologically limited, but the recent and increasing development of molecular and genomic tools has now equipped us better to face the challenge. Understanding how diversity arises and is maintained in nature has been a major question in evolutionary biology since ancient times (Lewontin 1974 Mayr 1982).
