In 1998, paleoanthropologist rick potts, of the smithsonian, 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?
