    I've actually got stuff like that posted here. Iran is a mix of Natufian, Pinarbasi, Yana, and Tianyuan.

    It's not really though. These are just distant proxies for the real mixtures sources, and the models will change when more proximate sources reveal themselves.

    Ah yes, I see your qpGraph on your blog. But can you directly show gene flow from Natufians/Levant into Ganj Dareh using straight D-stats?

    Well, no kidding. Zarzian is older than Natufians. Its stuff like Natufians will be from Kebaran.

    It's older. But, yes there are plenty of stats that show influence from something closely related.

    What is your take on this potential outgroup issue with Chimp in stats like these?

    Chimp Mota Ust_Ishim Devils_Gate_N 0.0133 2.813 53000 51606 1051378
    Chimp Mota Sunghir Peru_RioUncallane_1800BP 0.018 4.927 52934 51058 1053661
    Chimp Mota Kostenki14 Brazil_Sumidouro_10100BP 0.0162 3.475 47724 46205 960436
    Chimp Mbuti.DG Ust_Ishim Devils_Gate_N 0.0116 3.514 48239 47137 1051873

    And some comparative stats that Kale posted earlier in this thread:

    Chimp Mota Sunghir Peru_RioUncallane_1800BP = Z +4.9
    Mbuti.DG Mota Sunghir Peru_RioUncallane_1800BP = Z +1.6

    Chimp Yoruba.DG Sunghir Peru_RioUncallane_1800BP = Z +5.3
    Mbuti.DG Yoruba.DG Sunghir Peru_RioUncallane_1800BP = Z 0.0

    Chimp Mbuti.DG Ust_Ishim Devils_Gate_N = Z +3.5
    South_Africa_2000BP Mbuti.DG Ust_Ishim Devils_Gate_N = Z -0.9

    Your model is really interesting. However, could I ask you some questions about it?

    Is not ANE a bit too East Eurasian? I am just wondering why do West Eurasians and East Eurasians show a split 45 kya if there was so much gene flow between them afterwards?

    Also, is that ANA a Sub-Saharan component or something else? I am also a bit confused about the East Eurasian ancestry, what in your opinion are the proximal sources of the East Eurasian in Iran_N and ANE? I see its not Tianyuan per say.

    Is Hotu directly ancestral to Iran_N?
