Thanks BenLurkin. Apparently Iran's mullahcracy is in public relations mode right now. Also, in one article about this the simultaneity is actually thousands of years from end to end; additionally, the uncorrected (iow, too low) RC date for one multirow (domesticated and irrigated) barley sample was 14,000 years, about two thousand years before the oldest date here. :')
Still, I'm sure these scientists are -- you guessed it -- outstanding in their field.
