A depth of 2.7km, didn’t the Mediterranean Sea dry out in one of the recent ice ages, that must have been quite an interesting place 2.7km below sea level, well maybe ~2.5km below sea level if the sea level was quite a bit lower. Much higher pressure, I imagine it would have been a desert too. Wouldn’t a higher partial pressure of Oxygen have opened quite a few new evolutionary branches?
