Graph: evolution genomic sequence of bacteria when plotting distance from ancestor on the vertical axis vs. time
Charts: In vivo versus in silico- Two graphs showing evolution of digital organisms diversifying at different rates over time, depending on whether they are "fed" diverse resources. Background of slide is a photo of petri dishes showing actual bacterial colonies diversifying at different rates over time depending upon media upon which they are grown.
Caption: By running experiments on microbes for thousands of generations, researchers are exploring the roles of chance and history in evolution
