E-V16/E-M281 (E1b1b2)
Only ONE guy on this forum has it of the many people who took these tests. It is native to Ethiopia and Somalia and isn't foreign.
Correct.
Not all Arabians are J1. That's a meme. Only something like 3/4 or 3/5 of them are. Yeah, it is the majority, but definitely not all. They got many other paternal lineages. Including some T and E carrying ones that have been present there for thousands of years, especially variants of E-M123 and E-M78.
Most Maghrebis do not have paternal ancestors from the Arab invasion of the Middle Ages. Their paternal ancestors are mostly of Berber or Phoenician (in the case of Tunisians) origin. They shifted languages through elite dominance similar to how Anatolians (
present-day Turks) dropped Greek and Armenian for Turkic.
E1b1b (E-M215) is about 35,000 years old and does come from the Horn of Africa (paleolithic).
But most of the E1b1b in the world (like over 95%) is actually E1b1b1 (notice the extra 1) (E-M35) and is substantially younger (24,000 years old) and appears to have mutated and originated in Northern Africa and has more genetic diversity around the Mediterranean basin than in the Horn of Africa.
The macro-sub-variant Somalis have is even much younger E1b1b1a1 (notice the extra A and a 1) is 13,000 years old (neolithic) and has definitely without a shadow of a doubt originated in Northern Africa. A 13,000 year old population carrying this paternal lineage was found in Northern Morocco, see
https://en.wikipedia.org/wiki/Taforalt#Ancient_DNA They are very close to the origin date of that lineage and pretty much have settled the region in Africa it came from. Autosomally, this population were roughly 2/3 Eurasian in origin and 1/3 Sub-Saharan African. This is why East Africans with E-M35 lineages often also carry elevated levels of Levantine Neolithic affinity.
One more thing, Somalis have 40-45% non-L (that is non-Sub-Saharan African) maternal lineages and this is pretty much 1-on-1 in alignment with the estimated 40% Southwest Eurasian Neolithic ancestry. This is because women have less of a dynamic range when it comes to reproduction than men.
