This is interesting, but these do not solve the mystery of where the Ubaid originated from which as much as it has not been my thinking it may have been from the south beyond/around the Persian Gulf. There were known large migrations from the Caucasus to the southern regions c. 6,000BC but the Ubaid, supposedly, predate this by several centuries.
Recently I got a bit of free time and so I searched among my saved evidences (more than 15 years of researches
in many fields about pre-history) and came across to this:

You can not solve a problem with the same kind of thinking that you used to create it.
