What can a sequence of fossils show about evolution?
Answer and explanation
Correct answer: Gradual changes in organisms over time
A fossil sequence represents organisms that lived at different times. By comparing their preserved structures in chronological order, scientists can identify changes in body form and adaptations across generations. Thus, the sequence can provide evidence of gradual evolutionary change. It cannot prove that all organisms ended together, that ancient organisms lacked genes, or that inheritance was absent, so option A is correct.
