In parallel interviews, the biologists Niles Eldredge and Armand Marie Leroi discuss Eldredge's theory of Punctuated Equilibria (the idea that species evolve in sudden jumps) and Leroi's Darwinian study of revolutions in the history of pop music. Taking in Eldredge’s work on trilobite fossils, his vast collection of brass musical instruments, and Leroi's algorithmic cultural genealogies, the film reflects on the analogies and differences between biological evolution and cultural change.
