The input from more recent near eastern admixture has been greatly exaggerated by Levantist, nordicists, and woke liberals. I am not the only one who proposed such a model. Raveane et al. 2022 also puts this forward in a way. However we came to that conclusion independently. Moreover, Apulia and other parts of the south are show among the highest affinity to the Ancient Greeks, along with other specific Peloponnesian populations.
^^Natufian confounds the model, because it has a ton of Anatolia_N. There's also the Moors to consider, who brought some north African which also serves to confuse the model. Using minoan isolates that. The eastern Mediterraneans are mostly Anatolia BA, and that is represented in the model I put forward as well.
Roman_Greek has a levant shift yes, but I suspect the input is trivial in the grand scheme of things.
All of these populations have a fit of 4 or less using this model. Observe the autosomal make up of Island Greeks, not all are the same.
Also, many of the Greek colonies were founded by eastern Peloponnesians
