Answer 1

"Multiple mass extinction events have occurred in Earth’s history" is the statement that is a pattern in the fossil record.

• Scientists term and arrange fossils to infer when the organisms inhabited relatively to each other.
• The occurring fossil record tells the story of the past and exhibits the evolution of aspects over millions of years.
• Fossils are based on rocks and can be formed from hard parts of organisms like bones and shells, but soft parts do not form fossils adequately and fossils of body parts such as feathers are much more unusual.
• One pattern in the fossil record is the existence of forms with transitional traits, arranged in a sequential stratigraphic arrangement. This means that the fossil record contributes as evidence for evolution and it shows little changes in the structures of organisms as time moved ahead.
• "Multiple Mass extinction events" and natural disasters like depletion or volcanic eruptions can also be seen in the fossil record.
