DNA Study Sheds New Light On The Mysterious 9,000-Year-Old Shaman Burial In Bad Dürrenberg

Jan Bartek - AncientPages.com - The 9,000-year-old shaman burial in Bad Dürrenberg, Germany, is one of Central Europe's most spectacular discoveries.

Discovered in 1934 during construction works, the double burial of an adult woman and an infant has long fascinated scientists and the public. Who was this woman, and what was her relation to the child?

When examining the ancient grave goods, scientists could determine the woman buried in a seated position in Bad Dürrenberg was a shaman.

Genetic research now reveals the relationship between the woman and the child: the boy is not her son but a fourth- or fifth-degree relation. The phenotypic variants analyzed in the woman's genome inform us that she had a relatively dark skin complexion, dark straight hair, and blue eyes.

The burial

The unusual equipment buried with the woman comprises flint artifacts and solid rock tools, but also bone and antler artifacts, a piece of red ochre, a number of animal bones including the shell of at least three terrapins and partly pierced animal teeth. Together with deer antlers and originally six partly pierced boar's tusks, these finds are probably head/body ornaments. Due to the grave goods and bodily anomalies of the woman, the burial is interpreted as that of a shaman.

Subsequent excavations at the site as part of the preparations for the State Garden Exhibition 2024 brought not only new revelations about the deposition and positioning of the body to light, but also revealed a multitude of new finds, which could be clearly attributed to the burial. Besides the pierced animal teeth, remains of fauna, lithic artifacts and a large amount of human skeletal remains could also be recovered.

A recent article, published as a chapter in the conference proceedings Propylaeum, by Jörg Orschiedt (State Office for Heritage Management and Archaeology Saxony-Anhalt, LDA), Wolfgang Haak (Max-Planck-Institute for Evolutionary Anthropology), Holger Dietl (LDA), Andreas Siegl (LDA), and Harald Meller (LDA) details the results of recent work on the find, which included a DNA-analysis.

The shaman

The study finds that the 30- to 40-year-old woman was a gracile person with a body height of about 1.55 m, typical for the period. Notably, her skeleton lacked distinct muscle attachments, especially on the lower extremities, which are commonly found in hunter–gatherers.

At the base of the skull, there is an anomaly at the edge of the great occipital hole, in the form of a small constriction. This area is the imprint of an abnormally developed blood vessel. The first cervical vertebra is incompletely formed due to a congenital growth defect and has only reached 40% of the arch. The rounded end of the vertebral arch corresponds to the previously observed defect at the large occipital hole.

In this context, the researchers hypothesized that a pinching of the blood vessel with various sequelae appears possible with a corresponding head posture. The discovery of the second cervical vertebra among the finds of the re-excavation confirmed this. This vertebra also shows an anomaly, which is limited to the vertebral process in the form of a protruding bone clasp. This makes a blockage of one of the blood vessels leading to the brain plausible.

This can be caused intentionally by adopting a certain head posture. The consequences are unlikely to have been serious or hazardous to the person's health. However, it is conceivable that a nystagmus, i.e., an involuntary movement of the eyeballs, could be caused by the blockage of a blood vessel. This unusual feature might have been perceived as uncanny and when initiated on purpose may have reinforced or even justified her role as a shaman.

Genetic research revealed that the genomic ancestry profile of the shaman falls squarely within several dozen other Mesolithic hunter-gatherer individuals from central and western Europe, a profile which is commonly called Western (European) hunter–gatherer ancestry.

The phenotypic variants analyzed in the Bad Dürrenberg genome reveal that the shaman had a relatively dark skin complexion, dark, straight hair and blue eyes. This combination was quite common among hunter–gatherer individuals from Western Europe and the shaman lady shared this appearance with contemporaneous Mesolithic individuals from sites such as Loschbour, Mullerthal (Luxembourg), La Braña, Asturias (Spain), or Cheddar Man in Somerset (Britain).

The child

During re-excavations of the Bad Dürrenberg site, the partially preserved skeleton of an infant was discovered. The discovery of the petrosal enabled a genetic analysis of this individual. Since high-quality data from both individuals, and especially from the female, was available, researchers could also employ a newly developed method to scan the genome data for the presence, amount and length of tracts in the genome that are shared by two individuals, so-called identity-by-descent (IBD) tracts. This method, optimized to deal with missing data, as is common in fragmented ancient DNA, allows the detection of biological higher degree relatedness, and with reservations, up to the 10th degree.

Concerning the two Bad Dürrenberg individuals, the researchers found that the number and length distribution of identify-by-descent tracts that are shared between the pair is equivalent to genetic relatedness of the fourth or fifth degree. This degree of relatedness could be equivalent to four or five generations apart, assuming a direct line, which would make the adult female the potential great-great-(great)-grandmother of the boy.

The study was published in the journal Propylaeum
