The fossil record documents the existence, diversity, extinction, and change of many life forms throughout the history of life o
Marianna [84]

Answer:

Answered below.

Explanation:

The fossil records are beneficial in giving us. wide range of knowledge about fossils but sometimes these records are flawed, in that they are incomplete or misleading.

Many of the fossil records available are incomplete because some animals tend to decay within a short period of time due to their soft tissue. Also some are destroyed due to the movement of tectonic plates over time.

Another flaw scientists encounter is that there are no fossils which illustrate or represent the orderly transition from one organism to another. Fossils generally do not support the Darwinian theory of evolution as no evidence is found of ordered, sequential transition from simple to complex life forms as postulated.

These flaws are significant because they influence our knowledge and understanding of life forms and evolution.
