sergey [27]
<h2><u>Answer:</u></h2>

Fossil: is preserved pre historic life form present under ground at high pressure for a long time.Animal die and burried under layers of sediments.

It provides evidence about the history of life on earth. It also shows  different groups of organisms, including species,that have changed over time. Because the formation of any fossil depends upon the precise combination of conditions.

As the world changes, plants and animals change with time . From fossils we compare organisms of modern time with ancient , the species we see today are very different from species that lived in the past. Thus, the fossil record can be used to show that organisms changed to meet new condition.
