Answer:
Complex organisms evolved from more simple organisms
Explanation:
<em>Fossil records support the fact that complex organisms evolved from more simple organisms.</em>
<u>Fossils are remains of organisms that have been naturally preserved in rock forms. </u>
The study of fossilized remains of organisms has enabled scientists to establish the fact that earlier organisms are simple types and more complex organisms arose from them through a gradual process of change, otherwise known as evolution. Carbon dating of fossils enables scientists to establish the year the organism existed.
