I just came across something interesting. Some scientists think that the Archiflegreo volcano, near Naples, Italy, erupted c. 37,000-35,000 BC, driving out or eliminating Neanderthals there. This may have opened the door for modern humans (Aurignacians) to arrive there. http://popular-archaeology.com/issue...g-the-uluzzian A similar fate apparently befell the Minoan culture, c. 1450 BC, when the Akrotiri/Santorini volcano erupted, and the Myceneaeans invaded them. http://en.wikipedia.org/wiki/Akrotiri_(Santorini) http://en.wikipedia.org/wiki/Minoan_chronology http://en.wikipedia.org/wiki/Mycenaean_Greece (I think this is what caused the tsunami that drowned the Pharaoh's chariots during the Israelites' exodus from Egypt!) Interesting how some cultures may benefit from a major climatic event, while others lose out, isn't it?
