I mentioned in another thread that I've read about evidence that the Mediterranean Sea has become landlocked due to sinking ocean levels during various ice ages. This having the effect of opening up a far larger area of migration for early humans and also creating the most spectacular waterfall in history when the Atlantic Ocean once more poured through the gap. I am wondering if anyone on here knows about this? I've never even been to Niagra, this would be truly mindblowing. With forces like that at work is it any wonder that early man found no shortage of things to see as gods.
