Yohana.. is something more.. Biology proves Iberia was settled by Celtics and Iberian...Celts arrived the first (about XV century maybe?), Iberian later (About IX Century maybe?) and both groups stablished the biological substratum of the Spanish (Portuguese) Population. Phoenicians, Carthaginians, Romans, etc came in little groups didn´t change the main genetical characteristic of Population. The Peninsula is inhabiited by the same Celtics and Iberian arrived here.. they have changed their culture through centuries.
Why Spanish (Portuguese) and Finn are the European with more genetics rarities in their Genoma? Why?
Because the Peninsula didn´t change from a biological point of view from the arrival of the Iberians... (Spanish and Portuguese are the product of the Celtic and Iberians).
From Nature Magazin:
The degree of rare-variant differentiation varies between populations. For example, within Europe, the IBS and FIN populations carry excesses of rare variants (Supplementary Fig. 6b), which can arise through events such as recent bottlenecks, ‘clan’ breeding structures and admixture with diverged populations
So, Spanish (and Portuguese) IBS and Finns (FIN) have ecesses of rare variants because of: (Theories)
Bottlenecks
Clan breeding structures
Admixture with diverged populations.
In any case, the population in Peninsula don´t come from Lazio or from Latins Tribes.. it is a
scientific certainty.
Yes, they speak a "latinic" language... as Jamaican speak a Germanic languague...but I doubt Jamaican are a Germanic Tribe...
