Using Y-chromosome capture enrichment to resolve haplogroup H2 shows new evidence for a two-path Neolithic expansion to Western Europe
(Nature, 2021-07-22)
Uniparentally-inherited markers on mitochondrial DNA (mtDNA) and the non-recombining regions of the Y chromosome (NRY), have been used for the past 30years to investigate the history of humans from a maternal and paternal ...
CoproID predicts the source of coprolites and paleofeces using microbiome composition and host DNA content
(2020-04-17)
Shotgun metagenomics applied to archaeological feces (paleofeces) can bring new insights into the composition and functions of human and animal gut microbiota from the past. However, paleofeces often undergo physical ...
Effect Of Nb And Cu On The Crystallization Behavior Of Understoichiometric Nd–Fe–B Alloys
(IOP Publishing LTD, 2017-01-11)
In this work, we present a complete study of the influence of Nb and Cu addition on the crystallization behavior of Nd-lean Nd-Fe-B melt-spun alloys. Alloys with compositions Nd10-x-yFe84B6NbxCuy (x = 1, y = 0 and x = 0.5, ...
Microwear and isotopic analyses on cave bear remains from Toll Cave reveal both short-term and long-term dietary habits
(Nature Publishing, 2019-04-05)
Dietary habits of the extinct Ursus spelaeus have always been a controversial topic in paleontological studies. In this work, we investigate carbon and nitrogen values in the bone collagen and dental microwear of U. spelaeus ...
The Efficacy of Whole Human Genome Capture on Ancient Dental Calculus and Dentin
(Wiley, 2019-03)
Objectives Dental calculus is among the richest known sources of ancient DNA in the archaeological record. Although most DNA within calculus is microbial, it has been shown to contain sufficient human DNA for the targeted ...
Alterations and Contaminations in Ceramics Deposited in Underwater Environments: An Experimental Approach
(MDPI, 2021-07-15)
Ancient ceramics recovered after a long burial period have probably undergone several alterations and contaminations, introducing a chemical variability, affecting the ceramic’s natural variability. That is, the chemical ...
Genomic transformation and social organization during the Copper Age-Bronze Age transition in southern Iberia
(American Association for the Advancement of Science, 2021-11)
[EN]The emerging Bronze Age (BA) of southeastern Iberia saw marked social changes. Late Copper Age (CA) settlements were abandoned in favor of hilltop sites, and collective graves were largely replaced by single or double ...
A Great Step Forward. Lithic Raw Material Procurement and Management among Palaeolithic Hunter -Gatherers in the Basque Crossroads
(School of History, Classics and Archaeology, University of Edinburgh, 2020)
This paper is divided into three sections. The first section describes the historiographic evolution of the study of prehistoric lithic raw materials in the Basque Crossroads (in the north of the Iberian Peninsula) during ...
Quartzite Procurement in Conglomerates and Deposits: Geoarchaeological Characterization of Potential Catchment Areas in the Central Part of the Cantabrian Region, Spain
(Wiley, 2021-05)
Raw material characterization in Paleolithic archaeology has widened our knowledge of Middle Paleolithic societies. Procurement of raw material, specifically flint, has allowed the tracing of the mobility of both stones ...
