Ok well while it’s interesting this clade is in an Ethiopian it is still on the majority line of Somalis under T-Y16897 . Most likely repressing very ancient migrations back to Arabia from Horn of Africa being ancestral to some no Arabs/Horn-descended Arabs

Yoy may find these explantions interesting for how a small patrilineal lineage could slowly grow into 10%-15% of the Somali population.

Assume that all lineages are sharing a mating pool. If one lineage has a reproductive advantage of just 14% per generation (e.g advantaged lineage has a TFR of 2.28 each generation while all other lineages have a TFR of 2), then 3% of all the lineages sharing a mating pool will go extinct each generation. Differentials in reproductive success REALLY snowball when you are living in a steady state Malthusian society. Remember all human societies were Malthusian and spent something like 90% of their history at the steady state (Malthusian equilibrium) where population is static.
Add in the fact that bride price and polygyny were universal among Cushitic peoples, and it is all but guaranteed that some lineages would gain an advantage and their share of the population would grow, even in the absence of any violence.
This is a brilliantly researched article, they cite I.M Lewis’ seminal paper Force and Fission in Northern Somali Lineage Structure.

This isn’t definitive evidence for anything.

It wasn’t one single back to africa migration, they already know it was more saxibA small group who may very well have brought huge cultural change to the region such as camel pastoralism, asiatic admixture in our bovines and caprines and maybe even iron metallurgy. Leaving behind just a Y-DNA—if indeed those innovations were all brought by one group which I admit is just a guess based on timing—is frankly lightweight in terms of influence. They otherwise left nothing behind other than maybe OSA loanwords:

And the thing is, Somalis are a patrilineal tribal society like Peninsular Arabs, Pashtuns and the early Indo-Europeans. It's not hard for one lineage among several to just become overrepresented due to a founder-effect cos of one prominent chieftain or tol having a bit of political dominance for a time or whatever other reasoning one can cook up.
Arabians' actual ancestors definitely had a shit-ton of E-M35, T, J2 and many other lineages but that pastoralist patrilineal system did its work and over-repped J1 in various areas. I wouldn't take T's dominance in a good chunk of the northwest as a sign that there were actually A LOT of Arabians who spread it once upon a time.

HA Activist.
The sample you are referring to is actually from a Saudi man. He also uploaded his results on Yfull and is the newest addition to the tree.
Some people already pointed it out, but the Ethiopian flag on the page is due to the existence of a sample positive for this branch. It is absent from the tree because it isn't BigY upgraded.
