New Analyses Bolster Central Tenets of Evolution Theory

New Analyses Bolster Central Tenets of Evolution Theory: "Richard E. Lenski, a biologist at Michigan State University, has been following 12 cultures of the bacterium Escherichia coli since 1988, comprising more than 25,000 generations. All 12 cultures were genetically identical at the start. For years he gave each the same daily stress: six hours of food (glucose) and 18 hours of starvation. All 12 strains adapted to this by becoming faster consumers of glucose and developing bigger cell size than their 1988 'parents.'"
