Paglicci 23 is the name for human remains found in Paglicci Cave in Apulia, Italy that have been dated to 28,000 years Before Present. In 2008 a scientific team led by David Caramelli tested Paglicci 23 and found that mtDNA sequences corresponding to positions 16024-16383 were identical to the Cambridge Reference Sequence. The result was exhaustively tested for possible contamination and replicated in a separate test.The paper does not assign any mtDNA haplogroup to the results as the mtDNA segment is too small to draw any conclusions in this regard. Many haplogroups, however, are defined by mutations in this segment as indicated in the table below.
