What process does the fossil record primarily demonstrate?

• A. Genetic Variation
• B. Natural Selection
• C. Extinction and Evolution
• D. Ecological Balance

Answer: (C)

The fossil record primarily demonstrates extinction and evolution, showcasing the history of life on Earth over millions of years. Fossils provide direct evidence of the existence of various organisms at different points in geological time, illustrating how species have changed and diversified through evolutionary processes. By examining the sequence and distribution of fossils, scientists can infer how life forms have adapted to their environments, how new species have emerged, and how others have vanished from existence. This body of evidence highlights the dynamic nature of life and the process of evolution through natural selection, while also marking instances of extinction events that have significantly shaped biodiversity. The fossil record serves as a timeline, connecting past life forms with contemporary species, thereby enriching our understanding of both extinction and the mechanisms of evolutionary change.
