(PhysOrg.com) -- Gene duplications are arguably the driving force of organismal evolution – and if they survive, such duplicate genes will diverge in both regulatory and coding genomic regions. Coding divergences, in ...
Plants are DNA hoarders. Adhering to the maxim of never throwing anything out that might be useful later, they often duplicate their entire genome and hang on to the added genetic baggage. All those extra genes are then free ...

(PhysOrg.com) -- Roughly 10 million years ago, a major genetic change occurred in a common ancestor of gorillas, chimpanzees, and humans. Segments of DNA in its genome began to form duplicate copies at a greater rate than ...
