Cool map! :) I see what you're saying about the Mediterranean. I'm also noticing interesting things around the Bering Strait, Hudson Bay (or the lack thereof!), the Caribbean, the British "Isles", Japan, and Indonesia. As Mr. Spock would say, "Fascinating." :)
More at another time, lol.
Sounds good :)
Dr Robert Schoch (geologist/geophysist), speculates in his recent book Voyages Of The Pyramid Builders, that the inhabitants of Sundaland took to the seas as their land went underwater at the end of the Ice Age and took their custom of pyramid building with them all over the world. Interesting book.
BTW, Schoch says the underwater 'pyramids' found off the coast of Japan are natural formations. I saw a 'special' where he was swimming around these structures in scuba equipment.
