Authenticity of Amplified DNA

It is important to confirm whether the recovered DNA is authentic or not. For example, it should be noted whether it was derived from an authentic human, a modern human, an animal, a pathogen, or some other source. It remains possible that a sample can be contaminated during the experiment. It is therefore necessary for rigid quality criteria to be established to avoid more spurious and unsubstantiated reports.

Marota et al. have reported that DNA would be entirely degraded after slightly more than 800 years, and this result provides an indirect argument against the reliability of claims regarding the recovery of authentic DNA from Egyptian mummies and bone remains.[13]
