All of the options could reasonably be a part of the paper, and all of them would make the paper better. But one of the options is actually absolutely necessary: evidence of changing environmental conditions, with references- this is the correct answer.
This is because his argumentation is based on the assumption of "great variations in environmental conditions over time "- so he has to proove that there were those variations.

Answer:
The most appropriate answer would be "evidence of changing environmental conditions, with references".
As Mr. Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species in his paper, he must have mentioned evidence of changing environmental conditions with references.
In addition, he must have shown the effects of changing environmental conditions on the adaptations made by human species due to those changes.
