The linked article is about how the evolutionary biologist James Stroud solved the paradox of stasis by studying Anolis lizards that showed variation in traits over the short-term, counter to the long-term stasis they showed. His data indicated the emergence of a pattern resembling stabilizing selection, even when no stabilizing selection appeared at a per-generation timescale. The findings help to resolve the seeming paradox of stasis that previously challenged evolutionary biologists.
