How do the limitations of fossil records affect our understanding of the history of life on Earth?

Multiple Choice

Why are fossils considered important evidence for understanding evolution?

• They provide direct evidence of past life forms and their changes over time.

• They are only found in volcanic rocks.

• They show that all species appeared at the same time.

• Inorganic molecules in the atmosphere were transformed into simple organic molecules by sunlight and lightning.

• Simple organic molecules formed directly in the ocean from inorganic molecules.

• Organic molecules were created by volcanic activity.
