Does anyone have a date for when the Atlantic rose enough to burst across Gibraltar and fill the then dry basin of the Mediterranean? And, if so, what effect that had on the ecology and culture in the area? No doubt, the 5600 BCE flood, when it spilled across the bosphorus to fill the Black Sea had an enormous cultural and ecologic effect as well. Is there any analysis of this? -- Arachne V1.50;beta, NON-COMMERCIAL copy, http://home.arachne.cz/ %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
