I’m unconvinced by the whole argument that what is attractive is determined by the media rather than the other way around. IMO it’s more of a case of the media attracting a lot of people at varying levels of attractiveness and the most attractive having their usual advantage, hence there’s an unrealistic proportion of attractive people represented in the media (which then messes with our own metric because it skews what we think is common and rare beauty since we see media all the time).

Statues were kinda like the media back then, at least in that someone taking the time to carve one might have been more picky with who it was modeled after. I’d be very surprised if humanity didn’t always have a similar range of attractiveness to what we have today, though with less obesity going back to the times when there wasn’t so much surplus food (and it wasn’t made very accessible to the general population when there was).

I also suspect that the “older postures” before the “modern postures” were the result of control freaks gaining influence in schools and yelling at kids about their posture, and the “modern posture” is more of a case of people getting tired of that shit and ignoring them and going back to more natural postures.
