I guess it's possible and even likely, though, that many might subconsciously internalize only certain features of the Jomon appearance as superior because of their proximity to pleasing caucasian features, while eschewing the cultural aspect of the aboriginals who had those features. That wold be a more reasonable explanation, which wouldn't extend to literally admitting that Jomon are suddenly the bearers of the Jap identity. Many of that kind would find it insulting.
