"The Apportionment of Human Diversity" (1972) is the most highly cited research article published by geneticist Richard Lewontin in his career. This study's primary result--that most genetic diversity in humans can be accounted for by within-population differences, not between-population differences--along with Lewontin's outspoken, politically-charged interpretations thereof, has become foundational to the scientific and cultural discourse pertaining to human genetic variation. The article has an unusual bibliometric trajectory in that it is much more salient in the bibliographic record today compared to the first 20 years after its publication. Here, we show how the paper's fame was shaped by four factors: 1) citations in influential publications across several disciplines; 2) Lewontin's own popular books and media appearances; 3) the renaissance of population genetics research of the early 1990s; and 4) the serendipitous collision of scientific progress, influential books/papers, and heated controversies in the year 1994. We conclude with an analysis of Twitter data to characterize the communities and conversations that continue to keep this study at the epicenter of discussions about race and genetics, prompting new challenges for scientists who have inherited Lewontin's legacy.
