“…The disadvantage of uniparental markers is that their profiles are usually not individual specific, resulting in a much lower discrimination power (Kayser, 2007). The uniparental markers yields limited information compared with autosomal markers and does not allow one to obtain a complete reconstruction of possible kin relationships (Vai et al, 2020). However, the inheritance patterns of the uniparentally inherited markers make them powerful additions to kinship analyses using bi-parentally inherited autosomal data by clearly identifying false-positive assignments of kinship with Mendelian incompatibilities (Kopps et al, 2015).…”

Knowledge of kinship relations between members of wild populations is of great importance in ecological and conservation genetic studies. The bi-parentally inherited autosomal markers has been the Golden Standard in kinship analysis. However, analysis of kin relationship can be challenging in wild populations. The uni-parentally inherited markers and population demographic information can be helpful for identifying false-positive in kinship analysis. Here we showed how incorporating uniparental genetic and demographic information can improve the correct classification rate of kinship analyses by reanalyzing data of a recent study published in Science Advances. The application of next generation high-throughput sequencing to address fundamental ecological questions is of immense benefit to the field of molecular ecology, which could also generate uniparentally inherited organelle genomes together with nuclear data. We strongly recommended that uniparental genetic markers and demographic information be seriously considered in kinship analyses of wild populations.

“…Examining the occurrence of close genetic relatives identified by Olalde et al (2018, supplementary table 1, column 14) shows another possible bias in the C-EBA sample set and perhaps the C-EBA funerary record more generally (Supplementary Table 2). Close genetic relatives are identified in large-scale archaeogenetic studies by examining lengths and percentages of shared DNA sequences (Kuhn et al 2018; Schroeder et al 2019; Vai et al 2020). The specificity of relationships can vary depending on the method used, but generally relatives are often classed as either 1st order (sharing 50 per cent of their DNA—e.g.…”

Large-scale archaeogenetic studies of people from prehistoric Europe tend to be broad in scope and difficult to resolve with local archaeologies. However, accompanying supplementary information often contains useful finer-scale information that is comprehensible without specific genetics expertise. Here, we show how undiscussed details provided in supplementary information of aDNA papers can provide crucial insight into patterns of ancestry change and genetic relatedness in the past by examining details relating to a >90 per cent shift in the genetic ancestry of populations who inhabited Chalcolithic and Early Bronze Age Britain (c. 2450–1600 bc). While this outcome was certainly influenced by movements of communities carrying novel ancestries into Britain from continental Europe, it was unlikely to have been a simple, rapid process, potentially taking up to 16 generations, during which time there is evidence for the synchronous persistence of groups largely descended from the Neolithic populations. Insofar as genetic relationships can be assumed to have had social meaning, identification of genetic relatives in cemeteries suggests paternal relationships were important, but there is substantial variability in how genetic ties were referenced and little evidence for strict patrilocality or female exogamy.

“…Meanwhile, DNA studies of interred individuals may allow for certain hypothesised genealogical links to be proved (e.g. Vai et al, 2020), whilst stable isotope analyses could reveal movements undertaken by these people (e.g. Gregoricka, 2013; Gregoricka et al, 2020), thus nuancing patterning visible in the spatial data.…”

The Middle Holocene ‘funerary avenues’ of north-west Arabia

et al. 2021

The desert regions of the Arabian Peninsula and Levant are criss-crossed by innumerable pathways. Across large areas of north-west Arabia, many of these pathways are flanked by stone monuments, the vast majority of which are ancient tombs. Recent radiometric dating indicates that the most abundant of these monuments, elaborate and morphologically diverse ‘pendant’ structures, were constructed during the mid-to-late third millennium BCE. Thousands of kilometres of these composite path and monument features, ‘funerary avenues’, can be traced across the landscape, especially around and between major perennial water sources. By evidencing routes of human movement during this period, these features provide an emerging source for reconstructing important aspects of ancient mobility and social and economic connectivity. They also provide significant new evidence for human/environment interactions and subsistence strategies during the later Middle Holocene of north-west Arabia, and suggest the parallel existence of mobile pastoralist lifeways and more permanent, oasis-centred settlement. This paper draws upon the results of recent excavations and intensive remote sensing, aerial and ground surveys in Saudi Arabia to present the first detailed examination of these features and the vast cultural landscape that they constitute.
