Evidence from four rock layers is listed in order from oldest to youngest:
- Layer A (oldest): coal beds; fern fossils; swamp soil features.
- Layer B: cracked mudstone; dinosaur footprints; few plant fossils.
- Layer C: limestone with many shell fossils; wave marks.
- Layer D (youngest): ash layer; buried tree trunks; mixed plant pollen.
The evidence shows correlation over time, not direct observation. Which statement incorrectly links the life change to the environmental evidence?
