Pardon, I did not notice that you was responding to me.
So the following statement demands clarification then:
I'm sorry I was not more clear. Even I have trouble remembering what I wanted to say here. Well, I think my point was that there is a big proportion of south-europeans (maybe 50%?) which are not olive-skinned. These individuals seem to pale out (and some show freckles) to about the same degree (no scientific measurement here, just simple observation!) as many north-european natives if both live in northern latitude under sparse sunlight. I think this is one evidence that skin paleness has become somewhat independent (drift) from autosomal composition over time, regardless from which autosomal component it once originated.
individuals are making collective populations - types too but supposed to represent a previous stage, so previous populations mixed in new populations, with the results of crossed individuals showing all kinds of new and heterogenous distributions of traits -
my experience tells me there is no present pure population nor type - some populations are fairer, some darker - among fairer population, fair individuals are very common, dark ones very rare - in others, dark individuals are very common, fair ones very rare (the opposite) - but every time we see intermediary middle pigmented individuals: logical!
the 'olive' skin is the rule among true dolichocephalic 'mediterranean' type of any sort, and the majority among the populations where these types are dominant in % - other dark pigmented europoids show less "hard" colour, more a mate pale yellowish white skin than an 'olive' one -
the sun exposure tann every sort of skin, pinky white or middle of every sort or mate or 'olive', the darker hues tanning more and easier -
BUT I NEVER SEE AN EMIGRATED POPULATION OF SOUTH SETTLING IN NORTH AND BECOMING FAIRER OF SKIN AFTER THREE GENERATIONS (we have the case in France: Spaniards, Portugueses, Italians of South, Maghrebins...: only the same result we can have after a hard tanning summer when we pass the foloowing winter: our skin founds back its first colour, but doesn't become fairer than before -
under strong selective pressure (as in ancient times) the composition of genes submitted to it can evolved very quickly independently from the rest of the autosomals - they are themselves autosomals by the way! - but in modern times and without a new STRONG environmental pressure, the "cocktail" of autosomals associated with the selectionable ones keep on steady - we have enough vitamine D providers in our variated food -
+ NOT CONFUSE SOME INDIVIVUALS WITH WHOLE POPULATION
&: by the way too a survey about irish first agricultors conclude (?) milk was more absorbed for proteins than for vitamine D ... to look at later...
