Final answer:
Two examples of events in history that demonstrate continuity are the long periods of stability and prosperity in Ancient Egypt and the ongoing process of evolution.
Step-by-step explanation:
Two examples of events in history that demonstrate continuity are the long periods of stability and prosperity in Ancient Egypt interrupted by occasional invasions and disasters, and the ongoing process of evolution. In Ancient Egypt, there were cultural, spiritual, and intellectual traditions that remained unchanged throughout the entire historical period, especially in terms of the identity and role of the king and the significance of scribes. Similarly, evolution as an ongoing process shows continuity in the biological world, with certain patterns and periodicities being observed. For example, some scientists believe in a 26-million-year periodicity in the extinction record of marine species. While there may be some disagreement, the evidence suggests that evolution continues to shape life on Earth.
