the spanish study of Neus Solé-Morata 2017 of Barcelona University is an over 3000 people samples work of iberian Dna.
regarding Portugal, it shows: 37% is other haplogroups and 62.4% is R1b. then breaks the r1b as:
62% as M269 out of which 50% is P312 out of which 40% is DF27 and so forth.
So, make what you which of it...all I said is the P312 that are not DF27 are at par with the rest of IBeria. But the M269 that is not P312 is completely out of context in Iberia and only parallel to Nor-par-de calais and Alsace in france. - At a minimum its really weird for a east to west entry of R1b into Iberia, wouldn't you say so?
Secondly, Alsace is also on the same path as that Bell Beaker R1b- L151 with no steppe at Haute-Savoie, France. Just making a correlation. Look at an Hypsometric (terrain) map on google and its easy to see the Mountains path that population follow to travel.
Thanks, it seems better than the survey I referred to which spoke about one thousand people or not very much (concerning Iberia). Did your survey study French people too?
Because for I know all the surveys about France are old, and a lot of subclades had not been broken down. So if we want to compare what is comparable...
concerning highlands, yes very often BB crossed mountains and settled on uplands but they also settled seashores places; my impression, concerning PLAIN BB period, what is not the beginning and source, is that they occupied on one side mountainous regions maybe because they provide metals ores, and on another side, rivers and accessible shores surely for trade (network).
Concerning Southern Iberia, it seems the first huge fortresses were built since the Los Millares culture, beginning at 3000 BC or close, end about the 2200 BC; BB people seem appearing only at the very end there if not just after, so they were not the first cause of the decline of Los Millares which seems a society with collective tombs under tholos.
In subsequent El Argar culture, it seems more than an ethny was at work, or at least there were diverse modes of sepulture, two of them individual, the very new element.
It's why I would be glad to know which Y-haplo bearer was found under every kind of sepulture at Bronze Age and at what PRECISE time. But for this last point Radiocarbon is no so precise helas.
You know I'm rather for a central path for the most of Y-R1b L51, but it's only a first choice, I don't definetly exclude other way, at least for some groups of L51.
BB is a so special thing... and when we see proved Celtic speakers in the Tartessian territory spite Tartessian is a different language.
I 'll try to download the study you mention above, it interests me. Sorry if I pass for a destroyer more than a builder. Boa noite.
