Dir and garhajis is mostly T. Rest of isaaqs and other clans are mostly e1b1b1 (except some warsangeli who have hablogroup j)
Raises hell with any abtirsi going back to Samaale, doesn't it. The division even within the Isaaq is notable and strange.
There is supposed to be an Ethio-Somali gene that arrived circa 3KA, that is represented in modern populations at 30-50%.

"Populations in the Horn of Africa (HOA: Ethiopia, Eritrea, Djibouti, and Somalia) have substantial non-African ancestry [11]–[15]. The most recent genomic studies estimate 30–50% non-African ancestry in the Cushitic and Semitic speaking populations of the HOA resulting primarily from admixture around 3 ka [16], [17]. This timeframe corresponds to the estimated time of origin of the Ethiosemitic languages [18] and there are some carved inscriptions in South Arabian scripts associated with temple ruins and ritual items in South Arabian styles dated to the early first millennium BCE in the north Ethiopian highlands [19]–[23]. These linguistic and archaeological connections have been cited in the recent population genomic studies to support a hypothesis of high levels of non-African migration into the HOA around 3 ka."
I am thinking we need to look further into this.
