Question

Quizplus · Accepted Answer

The graph on the left shows that after only 500 generations, the fitness of the evolving strains had already increased compared to the ancestor strain, supporting statement A.

The graph on the right shows that the average fitness of the evolving strains increased substantially over the first 2000 to 3000 generations, supporting statement C. Therefore, the correct answer is E, as both statements A and C are true according to the data presented in the graphs. Statement B is not supported by the graphs as average fitness did not decrease substantially over the first 2000 to 3000 generations.
