Abstract
The Aven de la Boucle (Corconne, Gard, Southern France) is a karst shaft used as a collective burial between 3,600 and 2,800 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 favor of “continuous” deposits between 3,600 and 2,800 BCE, carried out by the same community, despite cultural changes reflected by the ceramic material.

Genomic data from 26 Neolithic individuals and 3 Bronze Age individuals from the Aven de la Boucle collective burial (France)
Raw sequenced data were obtained from half-UDG double-strand libraries sequenced on a NextSeq 500/550 High Output Kit v2.5 (2x75 Cycles) with dual barcoding.
All data generated by Bayesian modelling for Models 1 and 2.
Description of the data and file structure
Organism: Homo sapiens
Genomic data:
Fastq from Shotgun sequencing (2 files: R1 and R2 for each samples): individuals BOU17,BOU20,BOU22,BOU24,BOU27-31,BOU34-36,BOU38-44
Fastq from Capture1240K (2 files: R1 and R2 for each samples):BOU2,BOU12,BOU13,BOU23,BOU25,BOU26,BOU32,BOU33,BOU37,BOU45
BCL_bayesian-modelling:
One zip file (BCL_bayesian-modelling) with all data from the two Bayesian models: taking (BCL_M1) or not taking into account (BCL_M2) an individual (BOU32) whose 14C date and stratigraphic position suggest that the cave was used for funerary purposes during the Late Chasséen period. NA: not applicable
BCL_Tabl_SI_A_230331.xlsx is a Microsoft Excel file containing the primary radiocarbon references and results with indication of the dated individuals (column A), the archaeological layers and locations (columns B, C, D), the laboratory references (column E) and the raw results of 14C measurements Before Present and standard deviation (column F, G), the type of dated material (column H), the result quality score (column I) with reference to Binder et al., 2022, and the calibrated result Before Common Era (column J).
BCL_Tabl_SI_B_230331.xlsx is a Microsoft Excel file containing the synthetic results of the Bayesian modelling with indication of the stratigraphic phases and genetic clusters (column A), the number of individuals per phase/cluster (column B), the Bayesian model considered (column C), the a posteriori start and end modes of the phases/clusters Before Common Era (column D) following Lanos & Dufresne, 2019, or, if not applicable, the highest a posteriori probability density Before Common Era (column E) for the phases/clusters including a single individual
Folder BCL_M1 and **Folder BCL_M2 **contains the data corresponding to the two scenarios considered for the Bayesian modelling, namely :
- Application files available for loading the La Boucle models with ChronoModel software, Lanos & Dufresne, 2019, (BCL_M1_230404.chr; BCL_M1_230404.chr.cal; BCL_M2_230404.chr; BCL_M2_230404.chr.cal).
- The results (i.e., posterior density estimates) are based on ten thousand iterations for each dataset (MCMC method, Markov chain Monte Carlo) recorded in specific folders (Folder BCL_M1_230404_results; Folder BCL_M2_230404_results); the latter are given in the form of data files in CSV format (Chain-all-Events; Chain-all-Phases; Chain-name-of-Phase-Acronyme; Synthetic-Stats-Table) and HTML format (Log-MCMC-Initialization; Log-Model-Description; Log-Posterior-Distrib-Stats).
For both models, the Bayesian a priori are illustrated by diagrams in jpeg format (BCL_M1_230404_scene_events.jpg, BCL_M2_230404_scene_events.jpg, BCL_M1_230404_scene_phases.jpg, BCL_M2_230404_scene_phases.jpg)\
For both models, the Bayesian a posteriori results are illustrated by diagrams in jpeg format (BCL_M1_230404_results_phases.jpg, BCL_M1_230404_results_activity.jpg, BCL_M2_230404_results_phases.jpg, BCL_M2_230404_results_activity.jpg).
Specifically for model 2, the construction of Bayesian a priori is given in a synthetic figure in PNG format (Figure_Modele2_Annexes.png) and a folder includes the results of the activity traces for each phase/cluster in CSV format (Folder BCL_M2_230404_traces).
