That lineage seems very ambiguous only two upstream saudi samples from cosmopolitan Hijaz unlike the Somali J-P58 who are in a clear cut ancient Yemeni clade
Only one upstream sample is from the Hijaz, the other one is from the Asir area adjacent to Yemen.
If we are of Arabian origin as the current evidence suggests, then it is very likely to have arrived from Southern Arabia as there are other Y16897 lineages on FTDNA from Yemen and the Asir area. There is even an Indonesian with Hadhramaut ancestry. T-L208 is generally a North-Central or Eastern Arabian peninsula haplogroup, however, there is no denying that it also a historical presence in Southern Arabia, Oman more than Yemen where it is negligible.
It's definitely from the Arabian Peninsula just doesn't seem Yemeni the way Somali J-P58 does (branched off 2500 years ago from their fellow Yemenis).Somali J-P58 are probably responsible for camel herding, and the Sabean inscriptions found in the Republic Of Somaliland
Looking at how Waqooyi is heavily populated by T-Y16897, the genetic evidence is supportive of T-Y16897 also being a factor in the cultural and livelihood impact brought by South Arabian migrants in archaeological sites recently explored. Considering how Arab clans were/are confederacies, it is perfectly within logic that their ancestors would have been part of Southern Arabian trading networks and settlements in Northern Somalia.
