How can this be bad news?

Woman are getting better looking over time. Well, it's certainly good news for us heterosexual males, anyways. Although, the question is does evolutionary psychology explain everything. I remember reading somewhere, I think Psychology Today, about how, for some reason couples with traits that favor males (historically, think money or confidence) tend to have boys more and couples with traits that favor women (think looks, like the link above) have more daughters. I also wonder how that fits in to the above story. I also wonder how many evo psych stories are, well just so story. I don't know enough about evolution, as I haven't taken Bio since freshman year in high school, but sometimes I wonder what would actually disprove it. Almost anything can be made to fit, or so it seems to an outsider with little understanding, in to the "when we were hunter gatherers, we only knew a small group of people, so any thing we do is explained by that environment" stories. I am NOT claiming it's not the explanation of how we got to where we are, I just sometimes wonder if it's falsifiable. But, that's probably coming from a place of ignorance and misunderstanding.
