The fossil remains of organisms with skeletons are not found in the lowest layers of rock discovered. How is the lack of fossilized skeletons in the lowest rock layers best explained?

• Organisms with skeletons did not evolve until after these rock layers formed.

• The fossils of organisms with skeletons are only found in the oldest rocks.

• Fossil skeletons are usually crushed if other rock layers are above the ones they are in.

• Organisms with skeletons live only at the highest altitudes, which is where they turn to fossils.
