I was referring to this. I guess I misread it way back then as them having a common paternal ancestor within that timeframe, but there are mostly related within the last 1000 years.

I think that is autosomal. Patrilineally Europeans are relatively diverse. Some of them carry the Y of Neolithic Anatolian Farmers, others of Aryan Steppe invaders etc etc. With Somalis it is just two Cushitic lineages (or one Cushitic lineage and a Semitic one depending on who you ask, ).
