Richard Swann Lull (1867 - 1957)

Richard Swann Lull (November 6, 1867 – 1957) was an American paleontologist from the early 20th century, active at Yale University, who is largely remembered now for championing a Pre-Neo-Darwinian Synthesis view of evolution, whereby mutation(s) could unlock mysterious genetic drives that, over time, would lead populations to increasingly extreme phenotypes (and perhaps, ultimately, to extinction).
