We just got an extra 80K years.
While I often trash National Geographic (along with other popular-science magazines) in favor of true Scientific Journals, this one is a bit interesting, and states that the paper reflecting this find is due to appear in Geology. According to NeoGeo they’ve found some stone tools predating the earliest Homo Sapiens remains by 80,000 years. These tools are apparently sophisticated enough that they are attributed to Homo Sapiens, and date to about 276,000 years ago (the oldest Homo Sapiens remains are about 195,000 years old).
Of course the young-earthers will continue to deny, deny, deny. It is yet just another peice of evidence on a mile-high pile. I like to be able to throw more examples than they can refute at them in arguments, essentially using thier own tactics against them. These tools were dated using the argon-argon radiometric method, which is much more accurate than carbon or even potassium-argon. A nice article on argon-argon dating can be found at the Berkeley Science Review.
