"By definition, orthologs are genes that are related by vertical descent from a common ancestor and encode proteins with the same function in different species. By contrast, paralogs are homologous genes that have evolved by duplication and code for protein with similar, but not identical functions." What is the evolutionary significance of orthologous genes?...
