if you look at the northerner: European/caucasian and east asian (some chinese, japanese, korean) they all have the same charateristic, which is their mouth tend to become smaller (which make the female extremely cute or attractive)....this is the opposite of southerner (african and southeast asian) which their mouth tend to become wider thus their face tend to flatter
northerner, their front side of the mouth tend to become smaller
southerner (african, southeas asian) their front side of the mouth tend to become wider, thus this make their face actually tend to become flatter
you can look a the picture here



if you look at the west,
the most northerners characteristic: slimmer face, smaller mouth, slimmer nose n white skin
the most southerners characteristic: wider face, wider mouth, wider nose, black skin
they are like the exact opposite of each other
now on the east side of the earth (asian), since theres probably constant intermix between the northerner n the southerner, the difference between the two becoming blur
the east asian: wider face, small mouth, its like the blend of the two side, so you can say mongoloid is the mixture of northerner n southerner, caucasoid mixed with negroid
I wonder why the northerner tend to have shrinking faster upper jaw
while southerner shringking lower jaw.....this single gen that turn you caucasoid or negroid
since the northerner tend to have shorter jaw than the southerner and each generation, human jaw will be reduced or shrinking the characteristic can switch
and since the secret of human look is inside of its mouth we can predict what human look like in the future :
small mouth and reduced jaw make the eye almond shaped, weird could be alien human from future?
asian with the smallest mouth is korean:

it is no wonder they have the most attractive number of people among asian
