I don’t think I’m arguing against your evidence. It’s your idea that this difference in men and women’s strength is simply explained by a difference in testosterone. This claim does not nullify the questions posed in the article.
Both biology and the environment play roles in defining people’s personality and physique. Higher testosterone is only a piece of biology’s role, but it’s only loosely related to environment’s role. It’s not an unreasonable hypothesis to claim society’s artificial rules placed on women might have had an effect on women’s physique through things like sexual selection. This is why scientists still explore these things.
