Yes, that's the part that caught my attention. The initial flood was catastrophic, followed by more gradual raising of the levels to the current values.
IMO it just pushes the dates for movement along the Black Sea and into Mesopotamia and the Middle East to an earlier time. Those civilization didn't arise out of nowhere and this would have allowed them time to develop. After the initial deluge, they would have been forced out gradually as the lake increased and grew more saline.
