Explain how the fossil record indicates a long history of changing life forms.

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.

The fossil record shows that different species have evolved over time. The fossil record also provides evidence of how a specific organism evolved from earlier species. The fossil record shows that organisms have become more complex over time. It also shows which organisms lived during the same time period, which have a common ancestor, and which have become extinct.
