Abstract
The Aven de la Boucle (Corconne, Gard, southern France) is a karst shaft used as a collective burial between 3600 and 2800 cal BCE. The site encompasses the skeletal remains of approximately 75 individuals comprising a large majority of adult individuals, represented by scattered and commingled remains. To date, few studies have explored the potential of ancient DNA to tackle the documentation of Neolithic collective burials, and the funerary selection rules within such structures remain largely debated. In this study, we combine genomic analysis of 37 individuals with archaeo-anthropological data and Bayesian modelling of radiocarbon dates. Through this multidisciplinary approach, we aim to characterize the identity of the deceased and their relationships, as well as untangle the genetic diversity and funerary dynamics of this community. Genomic results identify 76% of male Neolithic individuals, suggesting a marked sex-biased selection. Available data emphasize the importance of biological relatedness and a male-mediated transmission of social status, as the affiliation to a specific male-lineage appears as a preponderant selection factor. The genomic results argue in favour of ‘continuous’ deposits between 3600 and 2800 BCE, carried out by the same community, despite cultural changes reflected by the ceramic material.

From from the article :
"Neolithic male individuals were found to carry Y chromosome haplogroups derived from I2a1 (n = 4), H2a1 (n = 2), G2 (n = 19) and R1b1b (n = 1). Except R1b1b (V88), such haplogroups are relatively common in western European Neolithic communities from both continental and Mediterranean expansion routes (i.e. France, Switzerland, Germany and the Iberian Peninsula). Although rare in Neolithic communities from western Europe, the haplogroup R1b1b carried by BOU38 (3626−3369 BCE) has been previously identified in western Mediterranean Early Neolithic communities from Els Trocs, Cueva de Chaves and Grotta Continenza. The high frequency of the G2a lineage (73%) is similar to what has been previously described for the contemporary cave of Les Treilles (90% of the G2a lineage; Aveyron, France). This may reflect a general predominance of this haplogroup in southwestern France at the end of the Neolithic. BOU44 and BOU17, dated to the second half of the second millennium BCE, both carry haplogroup R1b1a1b, consistent with previous records regarding the genetic impact of Pontic steppe herders."​
 
As a whole this survey doesn't show an heavy difference between these neolithic people and the Treilles survey one... even for uniparental markers. (I looked rather to the male ones)
