Mixed heritage itself likely makes facial features more distinct

I am not a science major, but
Empirically speaking, since Western countries are multi-ethnic, there is more mixed heritage, so as generations pass,
facial features become more distinct.
Especially if you visit various countries in Europe, Eastern Europe, and Asia,
Eastern Europe and the Middle East are at the boundary of Asia and Europe, where diverse ethnic groups mix the most,
so most people have very distinct facial features.
Of course, I am not going as far as to call it racial superiority, but it is a scientific
empirical fact that facial features become more pronounced.
It is also true that facial features have been becoming more distinct from our ancient ancestors until now.
In particular, you occasionally see Western-looking appearances in places like Thailand; I thought they were mixed with Westerners, but when I asked Gemini, it said most are actually of mixed Chinese descent. Mixed heritage involving Southeast Asian Chinese and Northeast Asians also has genetic characteristics that make facial features very distinct, similar to Westerners.
Even looking at celebrities from Thailand, that mysterious Western-like vibe is actually mostly due to Northeast Asian and Southeast Asian mixed heritage.
