Group selection as an explanation of the traits of individuals. Examples include bits of code in genetic algorithms, the analogs of genes in artificial-life simulations, and, if the physicist Lee Smolin is correct, the laws and constants of entire universes.
The lake starts out with little nutrients or life, but over time it begins to support a variety or species. For this reason the term "group selection" adds little to what we have always called "history.
