WebJan 26, 2015 · The evolution of opsin genes has received ample scrutiny, yet several other gene families deserve mention because of their likely role in phenotypic diversification. One of the most spectacular examples comprises the large and diverse family of olfactory receptor genes, which vary widely in number across vertebrate genomes ( 13 ). WebGene evolution is revealed by the study of genes that recently emerged in the evolutionary history of a taxon, so-called new genes. The interest in study gene evolution differs from conventional molecular evolution that has been focused on small-scale changes such as nucleotide substitutions, insertions, and deletions (Long et al., 2003 ...
