Epigenes versus Genes
Coyne discusses the evolution’s impact on genes, calling them “vestigial genes” and “pseudogenes” because they are silenced after the organisms with the selective advantage to have them off survive (66-73). However, in class, we briefly discussed the effects of epigenes on a few generations in a family of organisms. Briefly discuss a few common examples of epigenes on organisms’ selective advantages. To what extent do epigenes influence microevolution and evolution over a long period of time? Finally, how do you think recent developments in the field of epigenetics may influence pseudogenes, genes, and evolution? Provide examples of such developments.
