The diagram is missing in the question. It can be found in the following link: <em>https://quizizz.com › admin › quiz › 566b055c5cbcd49e2dd0fed1 › earth.</em>
The fossil evidence found in these sedimentary layers best implies that animals evolved bony skeletons after shells
Explanation:
Fossil is not only describing when organism lived, but it also gives information about the “progression and evolution of life” on this earth over millions of years. Fossils also give information that previous life in earth is different from present life.
According to evolutionist around 500 million years ago complex internal skeleton organism came into existence. They told fish had firstly evolved and they dominated the sea. Fossilization is very rare process.
They are similar to those of primary succession, primary succession occurs in an area without any initial. Succession always begins on a barren surface, whereas secondary succession be gains in environments that already possess soil. I hope this helps.
