The statement that best describes why most individual organisms never fossilize is "Conditions for fossilization are rare."
To understand this, let me explain the process of fossilization. Fossilization occurs when the remains of organisms, such as bones or shells, are preserved over long periods of time in sedimentary rock. However, several conditions need to be met for fossilization to happen.
Firstly, the organism needs to be buried quickly after death. This prevents scavengers and decay organisms from destroying the remains before they can be preserved. However, rapid burial is not a common occurrence in nature, as most organisms decompose or are consumed by other organisms relatively quickly.
Secondly, the organism needs to be buried in an environment that allows for the preservation of its remains. Generally, this means being buried in sediment, such as mud or sand, which can protect the remains from decay and prevent them from being destroyed. However, this type of burial environment is not always present, as it requires specific geological conditions.
Additionally, the remains also need to undergo a process called mineralization, in which the organic material is replaced by minerals over time. This helps to preserve the structure of the organism. However, the conditions necessary for mineralization are not always present, making it a relatively rare process.
Considering these factors, it becomes clear that the conditions required for fossilization are indeed rare. As a result, only a small percentage of the organisms that have lived throughout Earth's history have been fossilized.
