• A. It indicates that life began on Earth approximately 1 million years ago.

Answer: (B)

Verified step by step guidance

1. Begin by understanding what the fossil record is: it is the collection of all known fossils and their placement in rock formations and sedimentary layers, providing a timeline of life on Earth.
2. Consider the role of the fossil record in studying evolution: fossils show changes in organisms over time, supporting the theory of evolution by demonstrating gradual changes and adaptations.
3. Evaluate the statement about life beginning 1 million years ago: this is incorrect as evidence suggests life began much earlier, approximately 3.5 billion years ago.
4. Analyze the statement about simultaneous appearance of organisms: the fossil record shows a progression of life forms, not simultaneous appearance, indicating gradual evolution.
5. Reflect on the statement about species remaining unchanged: the fossil record provides evidence of changes and adaptations in species over time, contradicting this statement.
