Over geological eras, water has flowed in and out of the Black Sea basin.
This hypothesis concerns the occurrence of the last inflow and the primary point of controversy is whether the event was gradual or catastrophic.
Before that date, glacial meltwater had turned the Black and Caspian Seas into vast freshwater lakes draining into the Aegean Sea.
As glaciers retreated, some of the rivers emptying into the Black Sea declined in volume and changed course to drain into the North Sea.
The levels of the lakes dropped through evaporation, while changes in worldwide hydrology caused overall sea level to rise.
The rising Mediterranean finally spilled over a rocky sill at the Bosphorus.
