description: International symposium at the University of Tübingen, Germany, 8th-12th April 2001. This symposium explores the relationship between environmental change and the key events in the evolution and dispersal of the human clade, from its origin around 5-8 Myr to the expansion of Homo sapiens across the globe between 100 Kyr and 15 Kyr.
abstract: The retrieval of the first authentic Neantherthal DNA sequence from the type specimen from the Feldhofer Grotte by Krings et al. in 1997 was a milestone in the field of ancient DNA research. Since then, some more Neanderthal sequences have been published and one might speculate whether we are already on the way to Neanderthal population genetics. A significant improvement of DNA extraction techniques and PCR technology made such triumphs possible. Ancient DNA is highly degraded and present only in minute amounts in a sample. A major concern is the authenticity of deduced DNA sequences. In particular, this is an issue in studies aimed to retrieve sequences from hominid remains. Usually, fossils have been handled by humans and the genetic experiments will be conducted by humans; hence, there is a extraordinary risk of contamination of samples with contemporary DNA that might be indistinguishable from the authentic one. In fact, it turned out that contamination of samples with contemporary human DNA is the rule rather than the exception and the very sensitive PCR is likely to amplify the contaminating DNA instead of the authentic DNA. In my presentation I will summarize the state of the art of ancient DNA research with a particular focus on the impact of such studies on our understanding of human evolution. Furthermore, I will discuss the "criteria of authenticity" developed over the ensuing years in order to prevent dubious claims that might threaten the credibility of the field.
