A diagram shows two models for the tempo of speciation. Model a shows a punctuated model. The species changes the most as it branches from its parent species. It changes very little for the rest of its existence. A line from left to right shows the passage of time. Model b is a gradual model. It shows how species diverge from a parent species more slowly and steadily over time
