the fossil record is incomplete
|
Detailed explanation-1: -The fossil record is considered to be incomplete because fossilization is a very rare phenomenon. Most organisms decompose quickly after their death, and their remains dispersed. In order for fossilization to occur, the remains have to be covered by sediments and stay undisturbed for thousands of years.
Detailed explanation-2: -Which of the following are reasons why the fossil record is incomplete? Fossils can be destroyed before they are collected.
Detailed explanation-3: -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-4: -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. ‘
