A possible way to differentiate between Adnanite and Qahtanite-descended Arabs?

[J2tunisian]

Someone from another forum has shown me this method.
Apparently, if you model with neolithic ancestry at x0.5 ADC, Arabs with adnanite ancestry will shift towards ISR_N while those with Qahtanite ancestry will shift towards Jor_N.
Also seems applicable to a lesser extent to other populations.
What are your thoughts on this?

this is just Arabian mythology. Nothing to do with reality.
Here is a map for Arabians (made with Kmean algorithms)
We can see that they have split in 2 directions:
1st direction : toward iranians
2nd direction: toward levantine (what you call adnanite).
Only one group seems to remains "pure arabians".

What explains this drift then? Obviously, I don't assume the component causing this is solely Arabian in Nature, but I further tested this using the Kuwaiti Awazam sample, Hilayli and Sulaym samples from NA, the Otaibah sample from SA, all of whom have Adnanite, and a Morisco sample from Grenada that's suspected to be from the Banu Al-Ahmar who claim Ansari (Yemeni) ancestry. The drift seems to consistently align with Yemeni/Adnanite lineages.
I find the idea that all Arabs are descended from 2 people a bit unbelievable myself, what I am suggesting rather is the possibility of the existence of a distinct genetic marker for pre-Nabtean peoples in Arabia or more simply "South Arabians".

Geography is key here not the patriarchal ancestor of the clan. Tribes that live in close proximity to each other will have more things akin like genetics regardless whether they ascribe themselves to Qathan or Adnan. You won’t even know who is who when you go to Saudi Arabia unless they told you.

I'm sure it's a big factor, but no doubt endogamy is also something to consider. BedouinB is in the levant to give one example.

Aren’t the desert regions of the Levant , Sinai etc generally considered to be an extension of the Arabian desert? Where exactly was Bedouin b located again? There are Bedouins groups that have spilled over into southern
Persia/Baluchistan via the strait of hormuz and the eastern desert of Sudan, Eritrea. They do practice endogamy like you said but it’s hard differentiating between the two groups solely based on Qathan or Adnan.

They are Palestinians from the Negev desert. Their lineages supposedly go back to Yemenite tribes. Some even trace their migration (and that of the Sinai bedouins) to the semi-mythological collapse of Ma'arib dam.

The Negev Bedouins are Arabs with origins in the peninsula.

Why do you consider the collapse of the dam to be semi mythical? The Marib dam is recorded to have been constructed and repaired several times by different rulers throughout its existence. Several South Arabian records attest to that. Yemen is known for many ancient dams some of whom are more than 3500 years old. The final major collapse of the Marib dam is believed to have occurred by many scholar’s around the year 145 BC so it’s not even that ancient for it to be mythical. The dam would have given them water and sustenance and without it tribes would migrate northwards towards the Fertile Crescent as most of Arabia excluding the southwest and Hejaz is inhospitable.

What explains this drift then?

The admixture from neighboors like all humans.

What are you talking about ? autosomal or haplogroup ?
because regarding the map I have uploaded it is autosomal cluster.
The Kuwaiti, the Hilali and Sulaym, the Morisco, all them do not belong to Arabian cluster.
please if you want to talk, provide some data.

The drift seems to consistently align with Yemeni/Adnanite lineages.

I don't understand what you are talking about.

we will never know if we don't find some buried samples. for the moment, we can clealy identify an arabian cluster, for sure this cluster itself may be a mix of different origins

This disctinction "Adnanites" vs "qahtanites" is more folkloric than cultural or ethnic.
