B) Gaps in the fossil records will never allow us to fully understand evolution. C) Scientists studying evolution typically present ideas with very little evidence, leaving it to others to find proof of their ideas. D) Much of the science of evolution is based on speculation that can easily be changed when scientists think of new ideas.

Answers

Answer:

Aspects of evolution are constantly being challenged and explored in light of new evidence

Explanation:

The whole idea of evolution has to do with the fact that organisms developed into their present form from simpler life forms. According to Oxford dictionary, evolution is; ''the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.''

Evolution depends on evidence from fossil records. Evidences that support the theory of evolution continue to be amassed as science advances. Hence, aspects of evolution are constantly being challenged and explored in light of new evidence.

For this reason, the evolutionary history and development of whales is being hotly debated and there has recently been a major shift in our understanding of the processes used to detail whale evolution.
