    A systematic investigation of human DNA preservation in medieval skeletons

    Abstract

    Ancient DNA (aDNA) analyses necessitate the destructive sampling of archaeological material. Currently the dense inner portion of the petrous pyramid, the location of the skull that houses the inner ear, is the most sought after skeletal element for molecular analyses of ancient humans as it has been shown to yield high amounts of endogenous DNA. Destructive sampling of the petrous pyramid, assuming its recovery, is often not recommended for highly valued specimens. To investigate alternatives, we present a survey of human aDNA preservation for each of ten skeletal elements in a skeletal collection from Medieval Germany. Through comparison of human DNA content and quality we confirm best performance of the petrous pyramid and identify seven additional sampling locations across four skeletal elements that yield adequate aDNA for most applications in human palaeogenetics. Our study provides a better perspective on DNA preservation across the human skeleton and takes a further step toward the more responsible use of ancient materials in human aDNA studies.

    Differential DNA preservation across these elements was investigated in individuals excavated from the church cemetery associated with the abandoned medieval settlement of Krakauer Berg, near Peißen, Saxony-Anhalt, Germany

    Radiocarbon dating of ribs from each individual (performed at the Curt Engelhorn Centre for Archaeometry in Mannheim, Germany) placed the skeletal series in a time interval of ca. 1050-1402 cal AD (Table 4).

    I couldn't find mtDNA

    The J2b-L283 sample is L283>Z631, may possibly belong to one of the downstreams that are found in Eastern Europe.

    There isn't any additional information on the E-V13 sample yet, however I personally believe that this sample will turn out to be E-L540. I say this as a Medieval sample from Czechia belongs to this branch of V13, and as a cluster it is concentrated in Eastern Europe.

    Just wanted to ask the public here, maybe someone knows.
    How could it happen that so many important aDNA papers are published in so short period of time? It could happen that no significant papers are published in 2-3 months, but just recently we got East Asian and Siberian papers, 2 papers about aDNA from France, 2 papers about aDNA from Levant, 1 paper about Ireland.
    I'm not going to calculate the probabilities, but it looks like they had a deadline "before 1st June".

    Just wanted to share how my 2019 and 2020 aDNA folders look right now. So 40 papers in total in 2019 vs. 34 in 2020 as of today, and it's not even June!

    based on the 'Vertebral Body' all three are R1a-L1029+ (R1a1a1b1a1a1c1)
    thus all also CTS11962+

    until the Ottonian conquest(928/29) this area used to be proper sorbian territory and still remained heavily 'wendish' after said conquest as indicated by the Sachsenspiegel of the mid13th century; the samples are likewise from the high-middleages the village Krakau in the Gau Nizizi/Nuzici in the Mark Lausitz(part frm. Saxon Eastern March) ruled by the house of Wettin; the village Krakau had its own church(samples) and was located on a mainroad but was abandon(wüstung) in the late-middleages 14th/15th century

    Any R1a in any of the three papers? I just saw one R1b and one R reported. Like Iran/Turan - no R1a?

    It's linked to the academic year, and stuff like exams, vacations, etc.
