D. There have been changes in Earth's lifeforms over time.
Reason: Different rock layers (older at the bottom, younger at the top) contain different fossils, showing that the types of organisms living in that location changed through time. This rules out A (lifeforms have not been the same), B (there were lifeforms present), and C (more than one kind lived there over time).
