But this view [random mutation] is being revised by discoveries of molecular mechanisms of mutation in bacteria, now translated across the tree of life.
These mechanisms reveal a picture of highly regulated mutagenesis, up-regulated temporally by stress responses and activated when cells/organisms are maladapted to their environments—when stressed—potentially accelerating adaptation.
