What do they have in common? The same type of Near Eastern ancestry? From Iran? Nope, that's a joke. Obviously, they share the same type of steppe ancestry. This probably has some very important linguistic implications.
The relevant Principal Component Analysis (PCA) datasheet is available
here. Below are two pairs of formal mixture models that support my inferences from the PCA.

But seriously, what's the direct link between populations like Tepecik_Ciftlik_N/Minoan_Lasithi and Namazga_CA/Dzharkutan1_BA, except some exceedingly distant farmer ancestry from the Fertile Crescent?
