“…The recovery of genome-wide data from multiple animal species from a single Pleistocene soil sample opens a new avenue compared to what has previously been learned from sediment DNA (Ardelean et al, 2020; Slon et al, 2017; Willerslev et al, 2003; Zhang et al, 2020). Using this data we were able to make inferences about the genetic ancestry and history of three past mammalian populations that lived in the Southern Caucasus ∼25 ka.…”

SummaryArchaeological sediments have been shown to preserve ancient DNA, but so far have not yielded genome-scale information of the magnitude of skeletal remains. We retrieved and analysed human and mammalian low-coverage nuclear and high-coverage mitochondrial genomes from Upper Palaeolithic sediments from Satsurblia cave, western Georgia, dated to 25,000 years ago. First, a human female genome with substantial basal Eurasian ancestry, which was an ancestry component of the majority of post-Ice Age people in the Near East, North Africa, and parts of Europe. Second, a wolf genome that is basal to extant Eurasian wolves and dogs and represents a previously unknown, likely extinct, Caucasian lineage that diverged from the ancestors of modern wolves and dogs before these diversified. Third, a bison genome that is basal to present-day populations, suggesting that population structure has been substantially reshaped since the Last Glacial Maximum. Our results provide new insights into the late Pleistocene genetic histories of these three species, and demonstrate that sediment DNA can be used not only for species identification, but also be a source of genome-wide ancestry information and genetic history.HighlightsWe demonstrate for the first time that genome sequencing from sediments is comparable to that of skeletal remainsA single Pleistocene sediment sample from the Caucasus yielded three low-coverage mammalian ancient genomesWe show that sediment ancient DNA can reveal important aspects of the human and faunal pastEvidence of an uncharacterized human lineage from the Caucasus before the Last Glacial Maximum∼0.01-fold coverage wolf and bison genomes are both basal to present-day diversity, suggesting reshaping of population structure in both species

“…Our model also fits well with recent archeological records from both sides of the Isthmo-Colombian area. Archeological findings in southern North America report early occupations as far south as central-northern Mexico around the LGM (Ardelean et al, 2020) and more widespread settlements in warmer pre-Clovis times (14.7–12.9 kya) (Becerra-Valdivia and Higham, 2020). The cultural heterogeneity observed among the oldest reliable pre-Clovis archaeological sites of South America (dated 15.1-14.0 kya) along the Pacific coastal zone (Huaca Pietra in Central Andes; Monte Verde II in South Andes) (Dillehay et al, 2017) and in the Pampas (Arroyo Seco 2) (Politis et al, 2016) can be explained considering a deeper chronological time (between 16.6 and 15.1 kya) for the Isthmian crossing that led to the initial peopling of South America (Prates et al, 2020).…”

“…Archaeological and genetic evidence suggest that the peopling of sub-arctic America started from Beringia before, during and immediately after late Glacial times (Achilli et al, 2018; Ardelean et al, 2020; Becerra-Valdivia and Higham, 2020; Braje et al, 2017; Skoglund and Reich, 2016; Waters, 2019; Yu et al, 2020). Initial settlement attempts were followed by a more widespread occupation that reached southern South America as early as ∼15 thousand years ago (kya) (Dillehay et al, 2017).…”

The recently enriched genomic history of Indigenous groups in the Americas is still meagre concerning continental Central America. Here, we report ten pre-Hispanic (plus two early colonial) genomes and 84 genome-wide profiles from seven groups presently living in Panama. Our analyses reveal that pre-Hispanic demographic changes and isolation events contributed to create the extensive genetic structure currently seen in the area, which is also characterized by a distinctive Isthmo-Colombian Indigenous component. This component drives these populations on a specific variability axis and derives from the local admixture of different ancestries of northern North American origin(s). Two of these ancestries were differentially associated to Pleistocene Indigenous groups that also moved into South America leaving heterogenous footprints. An additional Pleistocene ancestry was brought by UPopI, a still unsampled population that remained restricted to the Isthmian area, expanded locally during the early Holocene, and left genomic traces up to the present.

Optically stimulated luminescence (OSL) materials, enabling energy storage by capturing of charge carriers and then the energy conversion to light via photostimulation, can find many advanced applications in various fields, spanning from radiation dosimetry, optical data storage and security, environmental monitoring, biomedicine, clinical diagnostic, to archaeology and geology. At present, there are some blocks, including the development of nanocrystallization approaches, the tailoring of optical transitions, the control of trap distribution, and the understanding of OSL mechanisms, on the road to the exploration of OSL materials. This review gives an overview of the design, preparation, characterization, optimization, application, mechanism, and prospect of OSL materials. A short introduction of the fundamental principle and history of OSL materials is presented, followed by a summary of preparation and design methods, and a survey of OSL materials reported to date. The trap engineering, mechanism, and study methodologies of OSL are summarized, after which the widespread applications of OSL materials, in traditional and newly emerging fields, are reviewed. Finally, the merits and drawbacks of the OSL materials according to the relevant reports currently available are examined. The challenges and outlooks are highlighted and discussed in terms of five important aspects that merit future research.
