Detailed explanation-1: -There are gaps in the fossil record because many early forms of life were soft-bodied. The soft parts of organisms do not form fossils well. This means there is little information about what these organisms looked like. Any traces of fossils that there may have been were likely destroyed by geological activity.
Detailed explanation-2: -Solution: Fossils are used for tracing the evolutionary relationship between species and are examples of preserved traces of living entities. “The age of fossils cannot be determined.” is a false statement.
Detailed explanation-3: -So, the wrong answer is ‘If the fossil of an organism is found in the deeper layers of Earth, then we can predict that the extinction of the organism has occurred recently. ‘
Detailed explanation-4: -We expect the fossil record to be incomplete for all of the following reasons EXCEPT:-All biomolecules, including lipids and pigment molecules, decay immediately after death.
