Graph: evolution genomic sequence of bacteria when plotting distance from ancestor on the vertical axis vs. time
Caption: 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.
