Why are soft-bodied organisms less likely to leave a fossil trace than hard-bodied organisms?
1. All soft-bodied organisms live in the oceans, where it is not possible for fossils to form.
2. Soft-bodied animals went extinct too long ago to be preserved.
3. Soft body parts are less likely to be preserved than shells, bones, or teeth.
4. Soft-bodied organisms are usually compressed and altered to form fossil fuels.
