My claim about ancient foods in stone tools is accurate. It is what I was basing my claim on. It's called residue analysis. I'm not sure why any research would have told me otherwise. Do you expect me to be a geologist?
I admitted I was wrong in this case, but you apparently want me to somehow go back into the past and undo what I posted. Sorry, my time machine has been on the fritz lately.
And if that's not what you want, exactly what do you want? Do I need to make a public apology? What?
