Introduction

Every gene has its first day in evolution. Thus it is no surprise that gene origination is viewed as a general evolutionary process. The outcomes of these origination events, in which new genes are created in a genome, add evolutionary novelties in genetics and functions to organisms. New genes have attracted increasing attention among evolutionary biologists and laymen, impacting studies in multiple fields of biology and public understanding of evolution. The studies of new genes have attempted to reveal the origination process, the underlying mechanisms, and the consequences on evolution of species. It has become obvious that with more known about the specifics in evolution and biological properties of new genes, more challenging and interesting scientific problems have been also raised, rendering the studies a more active field.

General Overviews

Many authors have contributed detailed reviews of new gene evolution since the first general overview appeared in Long, et al. 2003, which was updated in Long, et al. 2013. This article attempts to provide literature for an overarching framework for understanding the general concepts and mechanisms of new gene evolution. For detailed reviews of studies of new genes generated by specific mutational processes, see Kaessmann, et al. 2009 (cited under RNA-Based Gene Duplication) and Innan and Kondrashov 2010. For overviews of the consequences of multiple mutational mechanisms of new gene formation, see Kaessmann 2010 and Ding, et al. 2012. Losos, et al. 2013 and Long, et al. 2013 provide comprehensive overviews of new gene evolution and its related issues. Chen, et al. 2013 reviews progress in understanding the role of new genes in phenotypic evolution.
