Black Sea deluge hypothesis

The Black Sea deluge is a flood theory proposed by William Ryan, Walter Pitman, Petko Dimitrov, and their colleagues in 1997. It would have taken place around 5600 BCE.

 The theory 
According to this theory, 7,600 years ago, the Black Sea was formerly a freshwater lake. Later, the Mediterranean Sea’s water rised and breached a rocky sill in the Bosporus and flooded the lake, transforming the so-called “Black Lake” into a brackish inland sea. The event flooded 100,000 km2(39,000 sq mi) of land and significantly expanded the Black Sea shoreline to the north and west.
