Final answer:
The fossil record shows that different groups of organisms have evolved over time, documenting the history of life and evolution of species.
Step-by-step explanation:
The correct statement about the fossil record is: D. The fossil record shows how different groups of organisms have changed over time.
Fossils provide solid evidence that species have evolved. They are the preserved remains of animals, plants, and other organisms from the past, offering insights into the evolution of forms over millions of years. Scientists analyze fossils to piece together the history of life, observing changes in species, adaptations to changing environments, and showing relationships like the common ancestry of whales, birds, and mammals indicated by similar morphologies.
Evolution can be described as a change in species over time. For example, the evolution of humans and horses has been documented through detailed fossil records. Similarly, dinosaur fossils serve as significant evidence of past life forms and the evolutionary process.
