Authenticity in ancient DNA studies.

Ancient DNA studies represent a powerful tool that can be used to obtain genetic insights into the past. However, despite the publication of large numbers of apparently successful ancient DNA studies, a number of problems exist with the field that are often ignored. Therefore, questions exist as to how reliable the conclusions of many of the published studies are. In this paper we outline first the problems associated with aDNA studies, and secondly present potential guidelines designed so as to enable non-specialist readers the opportunity to critically assess the quality of aDNA publications.
