A total of 51 ancient oak wood samples originating from various European archaeological sites, dating from the Neolithic period to the 18th century, were assayed for the presence of reproducible chloroplast (cp) DNA sequences. Five polymorphic chloroplast fragments were targeted. Only five of the samples could be fully genetically characterised, revealing four different oak cpDNA haplotypes. In all cases, the haplotypes detected on ancient woods and the haplotypes characterised from fresh samples from the same localities matched. Overall, this congruence is consistent with a genetic continuity between ancient and modern European oaks, confirming the hypothesis that the mapped genetic patterns largely reflect the original structure that established during the post-glacial. This stability of the genetic structure implies that, in the future, the technique could be used to infer or confirm the transport of wood by man, providing interesting perspectives for the genetic analysis of ancient woodsRead less <
