In an earlier project simulating quantitative traits/stabilizing selection in a human-Neanderthal model, I became a bit curious about some observed fitness dynamics that I wasn’t expecting.
I’m not sure if this is all that interesting or relevant, but at least it’s short.

Mean fitness is maximized in small populations under stabilizing selection on highly polygenic traits https://www.biorxiv.org/content/10.1101/2025.11.17.688329v1
