Why is the fossil record incomplete?

Question

Quizplus · Accepted Answer

The fossilization process is a rare event and it requires specific conditions to occur, such as rapid burial in sediment, lack of oxygen, and the right amount of pressure and minerals. Therefore, many organisms are not preserved as fossils, and even when they are, they may not be discovered due to factors such as erosion, geological activity, or limited excavation efforts. This means that the fossil record is incomplete and biased towards certain organisms and environments. Additionally, some organisms may not leave clear fossils, such as soft-bodied organisms, single-celled organisms, or organisms that lived in environments that are not conducive to fossilization.
