Religion And The Mt. Toba Eruption
June 20, 2010 2 Comments
I was recently checking on one of the blogs that I follow and came upon this little excerpt from a scientific paper and it got me going on a hunt for more information. See blog link below and thanks to Mathildas Anthropology blog for the brain jog. http://mathildasanthropologyblog.wordpress.com/
“The depositional position of the tephra in the Jurreru River Valley, together with new chronometric and geochemical evidence, indicates that the ash is a product of the 74,000 year old YTT event (Petraglia et al., 2007). The recovery of Middle Paleolithic assemblages in dated deposits below and above the ash provides the first firm archaeological association, helping to resolve some of the uncertainty about archaeological associations in India. The recovery of Middle Paleolithic industries without major technological changes after the ashfall, indicate that populations survived the super-eruption. We have suggested, based on a variety of datasets, that modern humans were present in the Indian sub continent before the super-eruption, and that these populations survived this event.”
Searching a little further I found this Paper from the University of Oxford
“An area of widespread speculation about the Toba super-eruption is that it nearly drove humanity to extinction. The fact that the Middle Palaeolithic tools of similar styles are found right before and after the Toba super-eruption, suggests that the people who survived the eruption were the same populations, using the same kinds of tools, says Dr Petraglia. The research agrees with evidence that other human ancestors, such as the Neanderthals in Europe and the small brained Hobbits in Southeastern Asia, continued to survive well after Toba.” University of Oxford, UK
Continuing my search a bit more I found the following information on the dating of the YTT (Toba event), and for you Young Earth Creationist’s (YEC’s) who erroneously think that C-14 dating is wrong, you will notice it didn’t make use of this particular bit of science.
“Toba ash has been dated using the K-Ar, the 40Ar/39Ar and oxygen isotope/biostratigraphic methods. The abrupt drop in sea water temperature was determined with the oxygen isotope (O18/O16) method. The diverse methods used on a variety of Toba materials are in rough agreement as to the dating of the event: it definitively took place sometime between 77,000 and 69,000 years ago.” George Weber @

So basically what all of this stuff is saying is that modern type Homo sapiens were living in India sometime before about 75,000 years ago, and they were making tools and procreating and in general doing what humans do, and we have proof of this. And then this same info is saying that after the Mt. Toba eruption—which is thought to have cooled off the earth and caused a 1000 year lengthening of a ongoing cold snap that the earth was undergoing at the time, and caused a human population bottleneck where breeding pairs, on earth, may have fallen to as low as 10,000 people. In other words, near extinction of the human race—We were still around, albeit in smaller numbers. Whew!
This is pretty reliable data and it shows once more that humans have been walking the earth for many tens of thousands of years and leaving evidence behind that men can find, research, and interpret to determine that we were not placed on a newly created earth by some sky-god only 6,000 or so years ago, and also confirms that the Adam and Eve story is just myth…they never existed.
