Ahmedabad: Evolution is considered a process that spans thousands of years, but what if one can observe DNA-level changes happening in a species in real time?
An international study helmed by researchers from Stanford University, University of Pennsylvania, and Ahmedabad University observed drosophila (fruit fly) over a period of four months. In that period, the flies were subjected to different extremes such as lack of food, water, and high temperatures. The experiment underlined evolution in the flies generation after generation, in which every surviving batch was making the next more resilient.
