“Astounding diversity” of methods for gene creation

In sum, recent work in genomics has laid bare

an astounding diversity of mechanisms underlying the birth of more recent genes. Almost any imaginable pathway toward new gene birth seems to have been documented by now, even those previously deemed highly unlikely or impossible. Thus, new genes have arisen from copies of old ones, protein and RNA genes were composed from scratch, protein-coding genes metamorphosed into RNA genes, parasitic genome sequences were domesticated, and, finally, all of the resulting components also readily mixed to yield new chimeric genes with unprecedented functions.
