I found an old calculator by Dienekes, it requires various skull mesaurements, one of them is the cephalix index, it's 77.5 in my case (mesocephalic). It says I'm "proto-europoid"
proto-europoid, inded!?!
in fact so a CI can be the evolution of a type (hypothesis) OR the crossing between two very different types but with a predominance of the more dolichocephalic -
I've no proof but after personal observations, it seems to me skulls can take very various and opposed and astonishing forms through crossings, it could prove that more than a genes pair is involved in the genotype - that doesn't exclude that more common forms show very more often in a population, according to "pure" types or mixed types numerically dominant.
so meso or subdolichocephaly can be the result of ONE type or of MORE than ONE type - a diagnostic implies other measurements and shape observations (left aside possible deformations by disease) -
as a whole, on CRANIA, all the means from Paleolithic to early Neolithic in Europewere under 75, the most between 71 and 74 - EXCEPT in the Alps and Jura were roughly some 82-84 were found since the 6000 BC -
the first mediterranean Neolithic men shew as a whole CI's of 72-73 as means, and the so called braycephals of Mugem were fornt-to-rear compressed skulls, their supposed true Ci's being mesocephal rather than brachycephal (and yet we have to take inaccount the terminology for SKULLS where 80 is already considered as "brachy"...
the Cro-Magnon phylum shew a tendancy towards sub-dolichocephaly, with means of 73 to less than 75 - constant enough -
&: when we find CI's about the 77-80 on crania, whe have to examine the shapes and compare the middle element to the other elements: is it an homogenous serie of skulls between 77/80 or only a MEAN with extremes form say 68 to 94??? (it exists!!!)
in SOM late Neolithic there were 'mediterranean' skulls very recognizible for shapes, found too in caves of the southern France Causses, about the 72-73, brachy's about 83-84 or more, with easily identifiable 'alpine' shapes, and , among the meso's, a serie of very "brutally shaped" skulls; named 'sequanian' type:
someones thought it was a naturally mesocepahlic type for its peculiar shapes - possible, but i rather think it 's a dominently 'brünnoid-capelloid' type (remnants of Hunters-Gatherers as among Michelsberg culture) with a slight accretion of 'alpine' or cromagnoid on way to 'alpine', already present on the France soils : my 'borreby-B' in formation??? -
all this to say: we can inheritate our C-I from genetically homogenous or heterogneous sources, and we have to take in account the time or the generation which is ours, to try to calculate the effects of way of life and environment.
