Why are fossils evidence of evolution but not the full story alone?
Answer and explanation
Correct answer: Because they provide evidence of ancient organisms, but not all organisms become fossils
Fossils are preserved remains, impressions or traces of organisms from the past, so they reveal earlier forms and the sequence of biological change. However, fossilisation requires special conditions, such as protection from rapid decay, and many organisms leave no preserved record. The fossil record is therefore incomplete and must be interpreted with comparative anatomy, embryology, genetics and other evidence. Option A captures both its value and limitation; B, C and D are false.
