B It indicates the exact cause of structural and
behavioral adaptations of organisms.
C It shows how the embryos of many different

of organisms have changed over time.

Answer 1

D

Paleontologists study and prove the change in form and functions of organisms throughout time in the fossil record.

Answer 2

The statement ''it shows that the form and structure of groups of organisms have changed over time' best explains how the fossil record provides evidence of evolution (Option D).

• A fossil can be defined as any preserved remains of once lived organism (e.g., a plant or an animal).

• The fossil record provides evidence of extinct organisms that can be used to trace the evolutionary origins of a given taxonomic group.

• This record (fossil record) is obtained from the ground in the sites where fossils are preserved.

In conclusion, the statement ''it shows that the form and structure of groups of organisms have changed over time' best explains how the fossil record provides evidence of evolution (Option D).
