Genome evolution (source code)

= Genome evolution

<Genome evolution> is change in the sequence, content and organization of <genomes> across generations. <Mutation>, <gene duplication>, deletion, <genetic recombination> and <natural selection> can change both individual sites and large regions. A duplicated <gene> can retain its original function, acquire a new role or lose function. Comparing related <genomes> helps distinguish these histories, but the history of one <gene> need not match the history of the whole <species>. <Talking Glossary of Genomic and Genetic Terms by NHGRI>[Genome; Evolution entry]{ref}
