Summary

What happens to wild isolates of Escherichia coli bacteria from all walks of life when you put them in a laboratory and starve them? In their Perspective, Rosenberg and Hastings discuss just such a scenario and explain the increased rate of stress-induced mutagenesis--a strategy that may hasten evolution--in starved, aging bacterial colonies derived from wild isolates ( Bjedov et al.).
