GENETICS:
Can Organisms Speed Their Own Evolution?

Marina Chicurel

Intriguing hints from cell and molecular biologists suggest that in times of stress, organisms may be able to crank up their mutation rates, helping accelerate their own evolution. But evolutionary biologists caution that the evolutionary origins and effects of the newly discovered processes remain uncertain.
