Why R1b couldn’t have been spread around Western Europe by the Bell Beaker people

Why the Beaker people could not have been the source of European R1b1 Geography & Chronology : R1b indubitably originated in Asia, like R1a and R2. R1b1b1 M73 and R1b1b2 M269 most likely arose in the Middle East, either in Mesopotamia or Eastern Anatolia. L23, the oldest subclades of R1b1b2, are found around the Caucasus, Eastern Europe, the Balkans and Anatolia. The next subclades in the R1b phylogeny are L51 and L11, which are found mostly in Central Europe, especially in and around Germany, not in Iberia. The Bell Beaker culture, however, clearly originated in central Portugal, then spread from Iberia northward and eastward. The oldest European subclades of R1b L51 and L11 should all be found in western Iberia to support a Beaker dispersal. That is however not the case, as they are found between Hungary and Scandinavia. 2 R1b-U106. It could be envisaged that L11 crossed by sea from the Balkans to western Iberia, and that the Proto-Celtic R1b-P312 aka S116 first appeared in south-western Iberia and spread with the Beaker folk from there. But then what of the other main subclade of L11, namely the Proto-Germanic U106 S21 ? How did it end up in northern Europe if R1b-L11 migrated by sea to Iberia ? The centre of genetic diversity of R1b-U106 clearly lies between the Benelux and Denmark.3 Steppe pastoralists do not suddenly become maritime traders. It is rather far-fetched that the R1b people stopped following the Danube and instead crossed the Alps, made thousands of boats to migrate to Corsica, then Sardinia, then all the way to Portugal and Galicia to start a new culture. How do steppe tribe with a long pastoralist tradition and riding on horses suddenly turn into a maritime people ? Additionally both Portugal and Galicia have the lowest frequency of R1b in Iberia, but plenty of E1b1b, G2a and J2.4 A successful large-scale, organised maritime invasion of Iberia from the Balkans is highly improbable. It would take thousands of well-armed soldiers to invade a densely settled place like the Atlantic coast of Neolithic Iberia. If the R1b people were numerous and powerful enough to do it, why not continue to Central Europe or even take over the whole Italian peninsula ? Why seek the furthest possible place as a launching pad to conquer all Western Europe ? That just doesn’t make any sense.5 The R1b sample from Kromsdorf did not belong to Beaker people, but to Proto-Indo-European from the Unetice culture or its immediate predecessor. Both culture co-existed side-by-side in that region until about 2200 BCE. The maternal lineage recovered from the Kromsdorf site look nothing like the typical Beaker mtDNA heavy from haplogroup H. They actually look typically Indo-European, a mixture or Caucasian K1, I1, T1a and Northeast European U2e, U5a1, W5a. The very detailed summary of ancient European mtDNA compiled by Brandt et al. 2013 is unequivocal on this matter. Haplogroups I and U2 were not found on any other Beaker site not any Neolithic site in Europe. They both first appear with the Indo-European Corded Ware and Unetice cultures see Supplementary Materials page 30/87.6 The most important argument is that Bronze Age and Indo-European values & lifestyle were not present in Iberia during the Beaker period. The Bell Beaker culture started as a late Neolithic or early Chalcolithic society. The R1b cultures of the Balkans were already in the Bronze Age. It is only because R1b had bronze weapons that they could overthrow the rich, advanced and populous Chalcolithic cultures of south-east Europe. They would have needed their bronze weapons to conquer Iberia too. So how comes that the early Beakers of Iberia had no knowledge of bronze working ? This argument alone is enough to destroy the hypothesis that R1b steppe people founded the Beaker culture in Iberia.
