Too bad what was said during that call or where it came from is not going to be reveled.
One more thing. I learned something VERY interesting about DNA from teeth.
It seems that since the enamel that covers your teeth is the hardest substance in your body, the DNA in the pulp of the teeth therefore is the most well preserved and uncontaminated specimen. Also, tends to be there after other DNA has been disinigrated.
That is an interesting fact....hmmm.
