Digital organisms and evolution

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
