What can be understood by comparing fossils in deeper and upper layers?
Answer and explanation
Correct answer: Changes in the history of organisms over time
In undisturbed sedimentary rock, deeper layers are generally older than layers above them. Fossils from these successive layers provide a relative sequence of past life. Comparing their structures and types can reveal that organisms appeared, changed or disappeared through geological time, providing evidence for evolution. It cannot tell only today's temperature, food taste or a common age for all organisms. Therefore A is correct, while B, C and D are unrelated or false.
