Evolutionary genomics: new genes for new jobs.
Whole genome sequence analyses have confirmed that gene duplication and divergence play major roles in genome evolution. But the details of how young, functionally redundant gene duplicates escape mutational degradation have remained elusive. Several recent studies show that new genes survive because they evolve new, and sometimes essential, functions.
