The correct answer is 2) the fossil record provides evidence of a common ancestor to many species.

Explanation:

The definition of a fossil record is “the record of the occurrence and evolution of living organisms through geological time as inferred from fossils.” By studying fossils, scientists learn how different organisms changed over time, which serves as the best evidence of evolution.

Moreover, there are examples discovered by biologists that showcase how some species had the same ancestors but due to various environmental factors, grew too far apart, losing common characteristics. Probably the best example would be humans and apes having a common ancestor.
