Six million years ago, the Mediterranean Sea nearly dried up during what is called the "Messinian Salinity Crisis". This movie shows a physics-based computer simulation of the breach of Gibraltar and the flood of the basin.
A similar event 10,000 years ago, in the then populated Black Sea basin, may have been the source of the Noah's Arc narrative.
