[SuicideFuel] Sisterpill is one of the things that makes me doubt the evolutionary aspect of attraction

I have seen so many extroverted attractive foids with introverted inceltier brothers, maybe it's because they are short, or maybe it's just the face, usually both
but this doesn't make any sense, why evolution makes 2 siblings who carry really similar genes
have such different SMV?

this is also why more Incels are created, the dad looks like a chad and is tall, and the mom looks like a Stacy,
but the mother's features are shit for males and she's short, so they end up reproducing inceltier or normie males and above average foid
