Given below are two statements.

Statement I: Different-aged rock sediments contain fossils of different life forms.

Statement II: Life forms varied over time and certain life forms are restricted to certain geological timespans.

In the light of the above statements, choose the most appropriate answer from the options given below.

Rocks from different geological time periods contain different types of fossils. This is because life on Earth has evolved and changed over time, with different organisms dominating at different points in history.

Life on Earth has not remained static but has evolved and diversified over time. Certain groups of organisms are typically associated with specific geological time periods, meaning that they are restricted to particular times in Earth’s history. For example, trilobites were dominant in the Paleozoic Era, while dinosaurs were prevalent in the Mesozoic Era.
