im not sure i believe the line that the scarf went this long with viable DNA
As far as human genetic material goes, the record for oldest Neanderthal DNA is held by a 100,000-year-old sample found in a Belgian cave. The longest-lasting sample of human DNA was discovered in northeastern Spain, and boasts a survival age of 7000 years. In both cases, techniques pioneered by Dr. Rhonda Roby allowed researchers to use mitochondrial DNA rather than the type found in the cell nucleus; although mitochondrial DNA only contains only partial genetic information, it provides sufficient evidence for identification and is present in greater abundance than nuclear DNA, increasing its odds of surviving.
you missed the part where it is contingent on ideal circumstances. dna on a scarf, existing for decades in non-ideal circumstances, being continuously contaminated, is NOT the ideal circumstance that they were talking about.

You missed the part where readable human DNA was found in a Belgian cave after 100,000 years.Or maybe you are of the opinion that the floor of a cave meets your idea of an ideal condition for preserving DNA.
