These fossils evidence can tell about the evolution of life as:
1. They show the existence of life in past as the oldest fossils are around 3.48 billion years.
2. They show how different life forms are related to each other.
3. Oldest rocks comprise of the fossils of the simplest organisms while complex organisms fossils are present in the newest rocks supporting the Darwinian view of evolution that complex organisms have evolved from the simple organism.
