Anonimo,
I don't think I said much about V-32. We are agreed that studies out of context have little value. This study includes but does not rely on the Denmark bit that you quoted:

You will notice multiple Somali studies, along with sample sizes and locations. The 77-85% in Somalis is E1b1b1a1 (M78), not V-32, which is a specific subclade. The clans are clearly confederacies, with the Isaaq even split between T and E.
There appear to have been multiple admixture events bringing T from the north, but the most recent work places one at 3000 YA, associated with the beginnings of Semitic languages in the Horn.

"According to Y chromosome studies by Sanchez et al. (2005), Cruciani et al. (2004, 2007), the Somalis are paternally closely related to other Afro-Asiatic-speaking groups in Northeast Africa.[167][168][169] Besides comprising the majority of the Y-DNA in Somalis, the E1b1b (formerly E3b) haplogroup also makes up a significant proportion of the paternal DNA of Ethiopians, Sudanese, Egyptians, Berbers, North African Arabs, as well as many Mediterranean populations.[168][170] Sanchez et al. (2005) observed the M78 (E1b1b1a1) subclade of E1b1b in about 77.6% of their Somali male samples.[167] According to Cruciani et al. (2007), the presence of this subhaplogroup in the Horn region may represent the traces of an ancient migration from Egypt/Libya.[169]
After haplogroup E1b1b, the second most frequently occurring Y-DNA haplogroup among Somalis is the West Asian haplogroup T (M184).[171] The clade is observed in more than 10% of Somali males generally,[167] with a frequency peak of 82.4% among Somalis in Dire Dawa.[172] Haplogroup T, like haplogroup E1b1b, is also typically found among other populations of Northeast Africa, the Maghreb, the Near East and the Mediterranean.[173][174]"

The background T in the large number of southern and non-Somali groups is typically around or less that 10% and probably does represent an ancient migration or influx from coastal merchants. But scores in the 82-100% range would seem to be something else. I think it is time to look a lot more closely at T, which is not likely to have been part of the migration from Egypt/Libya at these high levels, and is clearly concentrated in the area of Aksumite/Himyarite influence in the North.
IMO it is not at all too early to start looking at this stuff. New research areas are already indicated.
The clan breakdown of the samples used has not been given in any of the E1B1B figures you have provided apart from the Djiboutian one, it is therefore difficult to assume that they are reliable. I believe E1b1b, specifically E-V32, is the dominant lineage among Somalis but we are in the dark in regard to percentage stats.
It is not known if T accompanied J during the Semitic settlement of the Horn 3000 years ago. It is possible but bare in mind T has an older presence in Africa. I agree with you that its high percentage among Northern Somali clans, and Dir subclans in general, might indicate that it arrived in the Horn as a result of an ancient West Asian migratory event. However, until more research is conducted into HG-T subclades, we are stuck with no concrete evidence to support such an argument.
