How does the fossil record provide evidence of evolution?

Answer 1

The fossil record provides evidence of evolution by showing the gradual changes in species over time. Fossils of different species found in different layers of rock can be compared to show how organisms have changed and evolved over millions of years. For example, fossils of early reptiles show certain characteristics that eventually evolved into those seen in modern birds. Transitional fossils, which show intermediate forms between different species, provide direct evidence of evolutionary change. Overall, the fossil record provides a timeline of life on Earth and shows how species have changed and diversified over time, supporting the theory of evolution.
