    To anybody who really understands all the data, and not just some output from formal stats, it should be obvious that the CHG-related ancestry on the steppe is very, very old there.

    The genetic drift shared by Yamnaya, Piedmont_Eneolithic and CHG is off the scale, which means that whatever went into the making of Piedmont_Eneolithic was hanging out somewhere close to that western part of the Caucasus for thousands of years.

    There's no way that there's any input from Central Asia in Piedmont_Eneolithic.

    One of the reasons Central Asia might keep spuriously popping up in formal stats is because it mimics CHG on a global scale. Both are mostly Iran_N-like, with bits of ancestry related to Anatolia and EHG/ANE.
    If you need something just outside the Kotias-Satsurblia clade (which we do for steppe populations) and you can't use a ghost, you start with CHG and then artificially nudge the affinity down a bit with a globally very similar population, Central Asian Neolithic.
    To kind of add to/reiterate what General said, it's essential to understand any given piece of data in the context of all the other pieces of data.

    Nice post, I think it's very likely E-L618 came to Europe directly from North Africa, via Sicily and South Italy, and not with ENF via Anatolia, given the absence of E-M78-Z1919-L618 clades in Anatolian Neolithic (0/25). Can't wait for that paper with mesolithic and neolithic samples from South Italy (and Sicily?), it could give us the final piece of the puzzle. It's important to mention there is also archaeological evidence supporting this scenario, I wrote about that almost two years ago:

    As it has been established, the culture of the Mesolithic inhabitants of Crvena Stijena (present-day Montenegro) is firmly associated with the simultaneous cultures of North Africa, especially those of the so-called Capsian type, named after the site of Kaps (Gafsa) in today's Tunisia, whose sites lie from Mount Atlas in the west to the Barka plateau in the east. The coincidence in the forms of a large number of small tools (some of which are highly specialized tools for fine processing of skin and bones) are such they leave no doubt in the primary North African origin of not only these forms, but also of the Mesolithic population of Crvena Stijena.
    .....
    In terms of race, they belonged to a large group of Mesolithic and Early Neolithic populations for which the common name is Mediterraneans.

    It looks pretty complex because of how many populations are in there, and because the near east is missing probably 40,000 or more years of samples, but if you follow the path to create any one population, it's not as bad as it looks.

    Just giving a heads up here. I'm going to start looking hard at African pops and see how I can fit some ancients with modern pops. I know some had asked for this. Sorry it took awhile to get to it.

    This could be multiple posts as well.

    The first post is in progress. It will probably be very sizable and take a few days. I'm hoping to have it done by Saturday.
