Wait, perhaps the user is referring to a paper or article from 1983 that is top-ranked or highly cited in the context of discussing humans as animals. Maybe a paper in a scientific journal? Let me think. The field of sociobiology was popular around that time. E.O. Wilson's "Sociobiology: The New Synthesis" was from 1975, but there might have been discussions or follow-up papers in the 1980s. There's also the field of evolutionary psychology, which started gaining traction in the 1980s. A prominent work in that area is "Evolution and Human Behavior" by Jerome Kagan, but I think that's later. Maybe "The Adapted Mind" by Tooby and Cosmides, but that's 1992.
