Comments on: A REALLY Bad Day http://eatourbrains.com/EoB/2007/05/25/a-really-bad-day/ over 5 billion neurons served Wed, 25 Aug 2010 14:20:20 -0600 hourly 1 http://wordpress.org/?v=3.0.1 By: Steven Gould http://eatourbrains.com/EoB/2007/05/25/a-really-bad-day/comment-page-1/#comment-11621 Steven Gould Sun, 27 May 2007 18:58:45 +0000 http://eatourbrains.com/EoB/2007/05/25/a-really-bad-day/#comment-11621 Looks like it was longer ago than 13,000 years according the LDA's info. I guess we'd spread sufficiently in the southern hemispheres by then. So, 12,900 years ago is rougly 10,900 BC. The oldest known granary is 9,500 BC. Considering that fairly vast pre-Columbian North American indian nations vanished in the wave of germ pathogens, and, because their cultural artifacts were earth works and decomposable plant structures, we don't have a good record of them, it's conceivable that some of our early (non-stone building) civilizations were in existence when this thing hit. It's also interesting that the oldest civilizations in the western hemisphere are in South America, not the North, which should've been populated first. So, earlier waves of land bridge colonizers made it down into an area that wasn't as affected by both the impacts and the subsequent cooling, possibly resulting in a jump-start on civilization that North America didn't have.

I haven't been able to find the right sequence of search keywords to find it since then. Wonder if this was the event that caused that. Anybody here got a link?
