Essel says it seems that contact with skin, sweat, saliva or blood allowed the wearer's DNA absorb into the tooth.

In case you too were wondering how human DNA was in a deer tooth.

I was wondering how they even got any. I was under the impression that DNA doesn't last that long.

2 million years old sample is the oldest.

The 2022 Nobel Prize in Physiology or Medicine was awarded to Svante Pääbo "for his discoveries concerning the genomes of extinct hominins and human evolution".[38] A few days later, on the 7th of December 2022, a study in Nature reported that two-million year old genetic material was found in Greenland, and is currently considered the oldest DNA discovered so far
