Gene duplication is the major source of genetic novelties, because a duplicate copy may be free to change to a new function. Indeed, genome sequencing and statistical analyses have revealed that each eukaryotic genome contain numerous duplicate genes. Furthermore, there is evidence that a genome duplication occurred in the common ancestor of vertebrates and this might has been important for the diversification and organismal complexity of vertebrates.
