In 1998, paleoanthropologist Rick Potts, of the Smithsonian Institution, published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts provided evidence to support his claim that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Why might this not be the best article to reference?
Potts has no authority.
Potts was not objective.
The article may not reflect current knowledge.
The article was not reviewed by Potts’s peers.

IK this isn't English but o one answers it

The correct response is Option C. The article may not reflect current knowledge.

Explanation:

This article that was published by Rick Potts would be considered dated in the field of physical anthropology because it was published more than 20 years ago. In scholarly research, it is important to use articles that are recent and relevant to current advances in the field. Given that new finds in the fossil record and advances in dating techniques have improved, there are many new findings and theories being advanced. An article from 1998 would be missing many of those new insights. You would use this article perhaps in a literature review if it was influential and you were trying to give an intellectual history of the field.
