What type of events are typically seen in the fossil record?

This question is unfortunately incomplete. Here are the options given:

A) speciation

B) successive change in structures

C) extinction

D) All of these are typical of the fossil record.

The correct answer is D: All of these are typical of the fossil record. The fossil record can show speciation by fossils of similar age with similar body plan but some distinct differences. These observations also relate to successive change in structures, with successively younger fossils showing increasing changes from the original ancestor. Extinction events can also be seen in the fossil record if species evident in older fossil records are absent from the younger records.
