Answer 1

Answer: Option A

How organism change over time

Step-by-step explanation:

This is because intermediate fossils are form of fossils that are transitional because they are the transition change that occur between ancestral species and the descendents organisms. Therefore changes occur over time as organisms are been transited.

For example;

Amphibian or land vertebrate (Pederpes) have Intermediate form and it is transited between primary aquatic Upper Devonian amphibians

which is the anscestral and to early tetrapods which is the descendants.
