Summarizes a study of yeast under stress and the utility of whole chromosome duplication to population survival.

My question - did the stressor cause the duplication, or was the duplication just the kind of background level variation that happens all the time?

Last para contains a quote from someone at Baylor College of Medicine "who researches the molecular basis of genome instability and evolution". Waterloo!
