Understanding Somali Genetics

[Ashraf]

I’ve been attempting to increase my knowledge on Somali genetics, and wanted to test it by posting my OWN understanding of it so far. Feel free to correct me if I’m wrong.
Somali haplogroups- primarily e1b1b dominated by the ev32 subclade and a minority of T-L208 which is Semitic in nature and primarily found amongst a the Dir with some Isaaq also possessing it. E comes from our natufian ancestors- also a minority of J-
Somalias maternal haplogroup is mainly a series of L haplogroups which are purely African and from South Sudan I believe found amongst the nilotes.
In conclusion Somalis are a mix of two Eurasian groups Natufian/levant - E haplogroup , North African however I’m unsure of the haplogroup they brought. And 3 sub Saharan African groups- Nilotes, ancestral East Africans and a lil omotic.
Please understand I have a surface level understanding of this and only posted so people can correct me and expand my understanding. I do not wish to spread misinformation.

Furthermore we are around 38.4% Eurasian with it decreasing by 0.5% as you go south. The Arab ancestry is believed to be fabricated and was used to expand one’s social status. We are Cushitic have an Afro asiatic language, extremely homogenous as the mix happened almost 4 thousand years ago. We don’t assimilate, have the longest coastline in Africa on arguable on of the top 3 most important parts ( Morocco ,Egypt) one of the largest ethnic groups inhabiting over 1.1 million kilometres of prime real estate near the worlds most important trade route.

I believe the study that said 38% Eurasian incorrectly used eth_mota as the East African proxy which deflated the Eurasian percentage since ETH_mota has some eurasian affinity.

This is the Eurasian average for Somalis when the right proxies for our East African and Eurasian samples are used and ANA admixed samples like iberomaurusian and natufian aren’t included

here’s how it looks when u include natufian and iberomaurusian

So we’re 42%? Also can you explain why we have Moroccan/ North African dna?

It can be lower or higher than 42; I have around 40% from the south. Not exactly about this, but I'm guessing Moroccan/north African DNA (Iberomaurusian) blood was carried by the Natufians in very minimal amounts when they mixed with the Northeast Africans. If i'm wrong or someone knows real answer feel free to correct. Also I don't rlly think Somalis have omotic blood, if so it is very minimal
