Please help . - How do scientist explain the incomplete fossil record? A) The fossil record is limited to fossilized animals and the absence of fossilized plants.
B) Stasis occurs when the structure of a species in the fossil record does not change over a long period of time.
C) Not all organisms become fossils. Processes like erosion and mountain building can change rock layers, causing fossils to be spread over multiple layers or destroyed.

D) The adaptive radiation of mammals helps explain a rapid increase in mammal diversity of the fossil record after a mass extinction.

Scientist explain the incomplete fossil record because not all organisms become fossils. Processes like erosion and mountain building can change rock layers, causing fossils to be spread over multiple layers or destroyed.

Explanation:

Fossils are the remains of organisms that are found on the rocks after they die.
So, no one can be 100% sure about the complete fossil record because of the continuous process like erosion and other natural calamities.
The sediment must cover any organism's remains to start the fossilization process to start. Most of the organisms start decomposing before this process can be executed.
