I was wondering what ancestral components were behind modern Arabians outside Natufian adxmiture, trying to modelling MENA people using Iranian Neolithic, Natufian, ENF, Iberomausian, modern Yoruba and some other minor components leaves me with bad fits for peninsular Arabians especially(but also Samaritans and Assyrians)
I'm curious what is missing.

try a model with "Bedouin B".

they are a very ancient population but we don't have actual ancient samples of them yet.

Using that I got this:

95759

I find that there seems to be too much ENF in the Levant and Iraq and also too much Steppe ancestry, is there a problem with what I did or are the results reasonable?

those are very good distances. maybe try with Natufian instead of isr_c. but Natufians themselves were something like Anatolian+Iberomaurusian, so all the necessary components are already there.

I wanted to use components that were time-wise close enough, WHG is the only exception. Plus Natufian doesn't seem to do much other than pushing the admixture towards ENF and Bedouin, which doesn't seem to make sense to me.
