There was no time for your U152=Indo-European scenario. Basque R1b1b2 is almost exclusively P312+, and U152 is P312+. The difference in age between U152 and the other P312+ clades (and, in fact, between all of them and P312 itself) is negligible. In fact, the difference in ages of all the divisions of P310+ (which includes U106 and its clades, as well) is negligible.
I disagree, I would think that there are substantial difference in age there, and I would also like to point out how the Basques predominantly have rather unique subclades of P312+ which are basically found nowhere outside of the Basque-speaking (or, by extension in Antiquity, formerly Aquitanian-speaking) areas. I should ask then, in what time frame do you think did P312+ and it's subclades appear then?
So, chances are, whatever Basque R1b1b2 was originally, U152 was originally, as well. Either Maciamo is right, and R1b1b2 as a whole was the vector of Indo-European in Western Europe, or R1b1b2, including U152, whether Neolithic or otherwise, was non-Indo-European.
As I said, I was under the impression (from the dates given for various markers that P312+ occured well in the Neolithic, and that there was a significant timespan until the various subclades appeared.
I must say that while Maciamo's hypothesis is very elegant, however, I have the problem with it that it doesn't explain the abundance of clearly non-IE languages in Iberia in the Antiquity.
There is just no way U152 spread Indo-European languages to Western Europe.
Why not? I should explain, when I say in this context "Western Europe" I mean the Atlantic region (British Isles, Gaul, Iberia).
I don't think that is certain at all. First, Hallstatt and La Tene are two different things. One can say that Hallstatt influenced La Tene, but they are not the same thing.
Last time I checked, La-Tene evolved out of Halstatt. Or, in other words, La-Tene is the iron age successor of Halstatt. However, I admit I may be wrong about that.
Equating U152 with Hallstatt/La Tene Celts is a theory, mostly the work of a single enthusiast. It could be right, but it could be wrong, as well. More than one person has pointed out that U152 corresponds fairly well with the expansion of Alemannic German tribes. Others have seen it as primarily Italic, since it seems to be the most frequent R1b1b2 clade in Italy, and not just in Northern Italy, but all over the Italian peninsula.
Well, I find the reasoning very sound based on a few issues (I must admit that I do not know of the work of said single enthusiast, I came up with this idea myself):
First off, the high occurence of it in all regions previously inhabited by Celts (in particular, but not exclusively, P-speaking Celts).
As for U152 corresponding with the Alemannic tribes, this makes no sense at all, because it fails to explain the occurence of U152 in Belgium and the British Isles (notably Ireland!). The only reasonable explanation I see for the presence of U152 in Ireland is that it is associated with Celts.
I should make it very clear that the marker is merely associated with Halstatt/La-Tene, and not exclusive to them. It is likely that the marker appeared long before (ie, the Celtic/Italic split had not occured yet). However, I must admit that it is also entirely possible that we get "false signals" in the entire circum-alpine region as a result of the Roman period. The high occurence of U152 in Italy could be explained by both the presence of the Cisalpine Gauls, and by the fact that the Italics themselves had their own share of U152.
