when I say 'cromagnoid' it is a simplification: it is possible to imagnine 'cromagnon'-'alpine' crossing in ancient time but it is very possible in fact we have here the same phylum, being 'alpine' the brachycephalized form of some 'cromagnon' type: I think (and others more qualified than me) that the genuine modern infantile-like 'alpine' type is a foetalized form of the first brachycephalized 'cromagnon' achieved in Alps-Jura, when MY 'borreby cromagnoid' type is the not foetalized one (more northern):
I think 'borreby' is a mistaking term - an other 'borreby, MY 'borreby-brünnoid' type, could be the brachycephalized form of a phylum 'brünn-capelloid': we find easily the two types among Germans and Scandinavians, and the first type (cro-m) among GENUINE Lettons (very few among Lithuanians, by the way)- I found the second type among Hungarians too, more than among Czechs (I relativize all that: it was upon pictures only, not upon metric measures! but some evident traits can be seen -
based upon only TWO pictures of crania, it's true, I found the possible "ancestors" of the two types in Denmark-South Scandinavia: the 'borreby' real type (from the place of the same name) is very close to 'brünn' shapes: crania profil (high), more rugged lines, retreating brutal forehead, strong suborbitals, large orbits, very broad cheekbones (bizygoma) ,BUT less broad jaws (bigonials) - the other type, found too at Neolithical-Chalcolithical times in close region, has a steeper forehead, littler orbits, far less rugged crania lines BUT less protuding cheekbones, BUT also broader jaws... 2 skulls is very few, but I found among Swedish ice-hockey players the 2 types and the same (more often) among western Norwegians, side by side, with more often crossings (evident) between them and dolichocephallic types were 'nordic' is dominant -
&: the bracycephalization could be an internal phenomenon or a crossing result where the other traits of the supposed element disappeared progressively by raciation process ???
my opinion about the 'borreby' poor value terminology is backed up by the opinions of antrhopologists of the "old time"
