In a 2017 genetic study published in Current Biology, the remains of three CCC individuals buried at Kudruküla was analyzed.[7] The Y-DNA sample extracted belonged to R1a5-YP1272. The three mtDNA samples extracted belonged to U5b1d1, U4a and U2e1.[7]
In a genetic study published in Nature Communications in January 2018, the remains of two CCC individuals were analyzed. The male was found to be carrying R1 and U4d2, while the female carried U5a1d2b The CCC individuals were found to be mostly of Eastern Hunter-Gatherer (EHG) descent, and to have more EHG ancestry than people of the Narva culture.[8]
In a genetic study published in Nature Communications in November 2018, the CCC individuals studies were modeled as being of 65% Eastern Hunter-Gatherer (EHG), 20% Western Steppe Herder (WSH), and 15% Western Hunter-Gatherer (WHG) descent. The amount of EHG ancestry was higher than among earlier cultures of the eastern Baltic, while WSH ancestry had previously never been attested among such an early culture in the region.[9]
