A new study in the Proceedings of the National Academy of Sciences provides new evidence and support for a theory introduced in 2007 that suggested a comet may have exploded over Canada 12,900 years ago (the Younger Dryas Boundary), killing off the Clovis people and large animals and sending the earth back into an ice age. It refutes a study in 2009 that failed to replicate the findings of the 2007 study. The key findings in this new study resulted from sampling done at UofSC's archaeological site known as Topper.
