Wait, perhaps the user made a typo and meant "humans as animals," looking for a 1983 paper that explores that concept. For example, Richard Dawkins' "The Selfish Gene" discusses humans in evolutionary terms, but again, that's from 1976. There's also "The Evolution of Sex" by John Maynard Smith, but that's earlier. Another possibility is "Beyond the Blank Slate" by E.O. Wilson, but that's 1978. Alternatively, "The Ethological Foundations of Morality" by Robert Wright's book "The Moral Animal" from 1994. Not quite 1983.
