Acquisition of evolutionary novelties is a fundamental process for adapting to the external environment and invading new niches and results in the diversification of life, which we can see in the world today. How such novel phenotypic traits are acquired in the course of evolution and are built up in developing embryos has been a central question in biology. Whole-genome duplication (WGD) is a process of genome doubling that supplies raw genetic materials and increases genome complexity. Recently, it has been gradually revealed that WGD and subsequent fate changes of duplicated genes can facilitate phenotypic evolution. Here, we review the current understanding of the relationship between WGD and the acquisition of evolutionary novelties. We show some examples of this link and discuss how WGD and subsequent duplicated genes can facilitate phenotypic evolution as well as when such genomic doubling can be advantageous for adaptation.
