DNA From Cave Dust Reveals Genetic Roots of the Crimson Girl of El Mirón
Within the cave of El Mirón in northern Spain, intrigue surrounds a lady who was laid to relaxation there 19,000 years in the past. Her bones, coated in an earthy shade of crimson derived from the pure pigment ochre, led archaeologists to present her the title the “Crimson Girl of El Mirón;” new analysis, nonetheless, has taken a better look not at her red-hued bones, however on the soil inside the cave.
In a examine lately printed in Nature Communications, researchers analyzed sedimentary historical DNA, or sedaDNA, refining their understanding of the Crimson Girl of El Mirón’s heritage. As well as, they detected genetic proof exhibiting the constant presence of a number of carnivore species that always visited the cave when people weren’t current.

A Colourful Burial
Though archaeologists began exploring El Mirón in 1996, remnants of the Crimson Girl weren’t discovered till 2010. Her stays, together with an array of largely intact bones, have been hid in a slim area behind a limestone block etched with engravings. Researchers speculate that these engravings have been probably meant to mark the Crimson Girl’s burial web site — a “V” form carved into the block, for instance, might have signified a lady’s burial specifically.
The concept that the Crimson Girl was deliberately buried is lent extra credence by her ochre-coated bones. Those that buried her coated her physique in ochre obtained from a location outdoors of the cave as a sort of ritual providing. Sooner or later, a carnivore — presumably a wolf — dug up elements of the skeleton, together with a tibia that it gnawed on, leaving tooth marks. Researchers hypothesize that the skeleton was later coated in ochre once more and reburied, which means the involvement of ochre on this historical burial course of should have held some significance.
The Crimson Girl’s Ancestry
The researchers have been in a position to get better three human DNA samples of Solutrean lineage from sedimentary historical DNA; historical populations of the Solutrean tool-making tradition lived round Southwestern France and Spain in the course of the Final Glacial Most (LGM), the latest ice age in historical past that occurred roughly between 26,000 and 19,000 years in the past.
These folks had moved south throughout a interval of main local weather upheaval, previous the Crimson Girl and contributing to her DNA. The El Mirón cave, then, was possible a refugium for historical people throughout and instantly after the LGM.
Sooner or later, researchers will goal to get better nuclear DNA from the El Mirón sediments, which may present an much more detailed have a look at the genetic make-up of the Crimson Girl.
Carnivores within the Cave
The brand new examine reveals that El Mirón was residence to a number of animals all through the Paleolithic Period. Most notably, carnivores — just like the one which chewed on the Crimson Girl’s tibia — frequented the cave in the course of the Paleolithic. Bodily proof of animal stays is sparse within the cave, so researchers turned to sedimentary historical DNA from grime to complement their research.
The researchers recovered DNA belonging to carnivorous species like noticed hyena, Iberian lynx, and dhole, a species of untamed canine now solely present in jap and southeastern Asia. Carnivores comparable to these ones possible got here to the cave to scavenge leftovers from people. DNA from a number of herbivores was discovered as nicely, together with reindeer, rhinoceros, and wooly mammoth. The outcomes exhibit the potential of sedimentary historical DNA as a priceless technique that may fill in gaps within the archaeological report when bodily stays like bones are restricted.
