I agree with this premise. I've often looked at Google Earth and noticed this as well. Especially near the mouth. If we angle the image for a better
perceptive we can see what appears to be an under water troth or ancient flood/river valley up near the opening to the Atlantic.
Also the Nile, and the Po. The courses of these two rivers in particular shaped the bed of the meditteranean, and these courses are 1000s of feet
below their current level much farther in land as well. The Adriatic sea is itself formed by the Po cutting a path through the Balkans and the
Appennine mountains, much in the same way as the Colorado has shaped the Grand Canyon. Now imagine how the Grand Canyon would look after five million
years of being submerged under the sea. The Med was dry for about 1 and half million years, the mountains it had to cut through were mainly
sedimentary fold caused by the plate collosions that eventually locked in the basin and caused it to dry out. The opening where Morrocco and Spain
once touched, the trough is more likely, I would presume to be caused by plate movements, with water erosion, during refilling, as a secondary

All very true. Nobody is saying they were "Inhabited" It could have been an isolated area. Much like present day where there are still isolated
areas connected to present day dry land formations. Doesn't negate the possible scenario.
That those animals adapted to life without predators and did so until the arrival of predators about 6000 years ago is the best evidence that there
were no land bridges. Take the Pygmy Hippo for example, not only did it not need it's huge bulk to defend itself on the Med islands, but it didn't
need to use water as a retreat either, so these Hipposreverted to 'land based' knee articulation. Their joints all faced the 'right' way, the
defensive traits were all bred out. That not only takes a very long time, but it also takes their not being any need whatsoever to change, not the
slightest hint of a threat, ever, from arrival to demise. The land surrounding the Med, especially those mountain ranges, were densely populated with
predators used to hunting cautious prey. Had even one big cat wandered along a land bridge, those literally defenseless animals wouldn't have stood
a chance. So their very existence up to 6000 years ago negates any land bridges at any time after their initial arrival.
The Med, being as it is land locked to all intents and purposes is unlike the oceans. Some of the salt deposits that built up during it's dry
period, are a mile thick, nothing could have lived in the conditions that it takes to create the mineral deposits and crystalisation that studies have
revealed in the sea bed. It would have been like the Dead Sea crossed with Death Valley and the Grand Canyon, except for those mountains that reach
high enough above sea level that they would have drawn rainfall. But all other water was sucked into the salt, just as the Dead Sea sucks in the
Jordan and the rainfall from the Plains. Added to that, this was and is, an area where three plates collide, not to mention the arc of volcanos that
Etna is just one of. And, until competition for the seas, and a general lack of Lebensraum in general in the region, there was no need to even
venture out to explore those islands. Not all of them can be seen from the mainland...so they first would have had to clear the mountains of trees to
get a clear view and then have a reason to go their. Generally, in species development, an animal overcomes their fear of water for a reason, not
merely for the sake of it, although with humans, curiousity is often reason enough, it still has to develop the means. Taken in context with the
known history, natural and human in the region, I doubt that their were any land bridges of significance. Nothing like Dogger Bank certainly.
