Evidence of Evolution

Which of the following statements should Marley use to support her scientific explanation?

• I have shared my thoughts with other scientists, and they seem to agree with my explanation.

• Based on my knowledge and experience at the Natural History museum and the age of this bone, I would argue that it belonged to a flying dinosaur.

• After reviewing our results, comparing it to the research that has been conducted by other scientists, the evidence supports the possibility that the bone belonged to a flying dinosaur.

• In my observation, I noticed that the bone was hollow. I remember learning in college that birds have hollow bones, and considering the age of the bone I believe that the fossil belong to a flying dinosaur.
