Question

In 1998, paleoanthropologist Rick Potts 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 claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Which would most likely be found in his paper?
a review of modern human anatomical structure
evidence of changing environmental conditions, with references
the reasons competing hypotheses are wrong
his opinion of what will happen to the survival of the human race

Answer 1

evidence of changing environmental conditions, with references

Reason: a peer‑reviewed paleoanthropology paper would present empirical evidence and cite sources to support the environmental‑variation hypothesis. It would be less likely to be a general anatomy review or an opinion about humanity’s future (and while it might critique competing hypotheses, the central content would be referenced evidence).
