It's completely legal to hire people based on looks for positions that require it, e.g. salespeople, models, "experience managers". It doesn't mean we should do it. Especially not as we're evolving towards a developed, enhanced society. We're aspiring to such a society, not evolving. Evolution is an outcome, not a direction. It's not possible to say what we're evolving toward, except inasmuch as we are now closer to that ideal than we were 20 years ago. Not only that, but I'm not sure that's true. Today's norms are those that survived yesterday. The ones we think we want tomorrow are not always the ones we'll have. When sex sells, sex sells, regardless of whether you want it to sell or not. What has happened over the last 20 and more years is more a fine tuning of how to use sex to sell, rather than removal of sex from the sales process.
