Species can diverge from one another either gradually over time or suddenly in a punctuated model. In a punctuated model, new species change rapidly as they branch from a parent species and then change little for the rest of their existence, while in a gradual model species diverge from one another more slowly and steadily over time. The document discusses models of gradual versus punctuated evolution and their implications for the fossil record.
