Final answer:
The fossil record documents the evolution of life-forms throughout Earth's history, providing evidence for evolution and showing how life has evolved over millions of years.
Step-by-step explanation:
The fossil record documents the evolution of life-forms throughout the history of life on Earth.
Fossils provide solid evidence that organisms from the past are not the same as those found today and show the gradual evolutionary changes over time.
Scientists determine the age of fossils and categorize them to determine when the organisms lived relative to each other.
By studying fossils, evidence for evolution is revealed, helping us understand how life has evolved over millions of years.
