{"Image DocumentName": "Clicker Question 4During the Long-Term Evolution Experiment, what interesting phenotype evolved after ~33,000 generations?", "Image ImageDescription": "The E. coli evolved virulence and are now able to infect people. The E. coli evolved the ability to utilize citrate in the presence of oxygen. The E. coli evolved multicellularity. None of the above. Answer: B. In the LTEE, there was no selection for either A or C dictated by the experimental environment, so it is highly unlikely that either of these phenotypes would evolve, not to mention the complexity of attaining these traits would probably take a very a long time to evolve. The massive pool of unused citrate provided an ecological opportunity that was eventually exploited by the Cit+ clade that evolved.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
