There are deep scouring marks on the floor of the Med just inside Gibralter....this supports the theory that the Med was 'plugged' at Gibralter during the Ice Age and the Med nearly dried out.
When the 'plug' broke a monumental waterfall occurred at Gibraltar and slowly filled the med and eventually crashed through the barriers at the Bosporus flooding (Noah's Flood) that fresh water lake (Black Sea) about 7,600 years ago.
There was a time when people lived on the floor of the Med. and wandered around it for hundreds of miles.
When the Black Sea began to flood, the water rose about one foot per day...people were able to safetly walk away and I expect something similar when the Med refilled...walkaways.
The refugees from the Black Sea flood fled up the river valleys into Europe and took farming and their Indo-European languages with them.
BTW, the Med did completely dry out at least once but it was five million years ago.
Thanks for the reply, I’m a geologist I am familiar with the Mediterranean Sea dry out events. There is geological evidence in the massive salt layers all the events left behind those didn’t wash away they were already covered by additional sediments and persist to this day deep below the seafloor younger sediments. The time periods I am referring to 50000 and 100000 years bp the med had water in it deep waters at that.
There is other evidence of Neanderthal boat technology along with Homo Sapian our first species before we became modern H.Sapiens Sapiens all three species have shown long-distance open ocean crossings making boats is not hard especially skin on driftwood or bone boats, canoes and kayaks or Umiak. People have paddled all of those types across the Atlantic the Pacific and Med. One German paddled from Germany to Australia in a kayak. Launched from Peru a balsa raft built by hand with Stone age tools made it to Polynesian deep into Polynesia. A reed boat built to first Dynasty Egyptian levels crossed the Atlantic to the Caribbean. A Irish explorer took a cowskin and wood boat against the current from Ireland to New York also hand made to Stone age tech levels. Humans have crossed oceans long before writing was invented to document it. We are the third probably fourth species of humans to master ocean going boat technology. Homo Erectus era digs have yielded the tools needed to hollow out logs to make canoes,or catamarans or outrigger type.
