Abstract Species determination based on genetic evidence is an indispensable tool in archaeology, forensics, ecology, and food authentication. Most available analytical approaches involve compromises with regard to the number of detectable species, high cost due low throughput, or a labor-intensive manual process. Here, we introduce “Species by Proteome INvestigation” (SPIN), shotgun proteomics workflow for analyzing archaeological bone capable querying over 150 mammalian species liquid...

Significance We report the remarkable discovery of an early Aurignacian occupation, ∼5,000 years older than any Upper Paleolithic site in westernmost Eurasia. The archaeological and radiocarbon data provide definitive evidence that modern humans were western Iberia at a time when, if present all, Neanderthal populations would have been extremely sparse. This has important ramifications for our understanding process human dispersal replacement populations. results support very rapid,...

This study presents new models on the origin, speed and mode of wave-of-advance leading to definitive occupation Europe’s outskirts by Anatomically Modern Humans, during Gravettian, between c. 37 30 ka ago. These provide estimation for possible demic dispersal routes AMH at a stable spread rate 0.7 km/year, with likely origin in Central Europe site Geissenklosterle Germany reaching all areas European landscape. The results imply that: 1. arrival Gravettian populations into far eastern plains...

High-throughput proteomic analysis of archaeological skeletal remains provides information about past fauna community compositions and species dispersals in time space. Archaeological are a finite resource, however, therefore it becomes relevant to optimize methods proteome extraction. Ancient proteins bone specimens can be highly degraded consequently, extraction for well-preserved or modern might unsuitable the processing proteomes. In this study, we compared six on Late Pleistocene with...

Levallois technology, a hallmark of Middle Palaeolithic stone tool manufacture, involves sophisticated core reduction strategies that have major implications for understanding human cognitive and technological evolution. However, traditional methods analysing cores often fail to capture the nuanced variability in their morphology. This study introduces novel application three-dimensional geometric morphometrics (GM) quantify shape Nubian from Nile Valley Dhofar regions. By employing this...

The ability to exploit the deeper levels of cave systems is regarded as complex human behavior. Evidence that Neanderthals possessed this skill remains limited. site Escoural, in southern Portugal, worldwide renowned for Upper Paleolithic rock art was performed lowermost level cave. also preserved Middle sequences a deep chamber (P1) well an area today lies outside (P2). Due lack geoarchaeological analyses, it currently impossible clarify whether these materials reflect systematic...

The Upper Palaeolithic (UP) of westernmost Europe was marked by technological and cultural transformations abrupt climatic shifts. Iberian Peninsula, particularly southwestern Iberia, served as a refugia key eco-cultural niche, making it region for UP studies. Vale Boi, the only site in Iberia with nearly complete sequence, provides critical insights into technological, economical mobility patterns over time. This study examines lithic raw material procurement organisation at focusing on...

The Solutrean techno-complex has gained particular significance over time for representing a clear demographic and techno-typological deviation from the developments occurred during course of Upper Paleolithic in Western Europe. Some Solutrean's most relevant features are diversity characteristics lithic armatures. These have been recurrently used as pivotal elements numerous Solutrean-related debates, including chronological organization across Iberia Southwestern France. In Southern...

Successive generations of hunter–gatherers the Late Glacial and Early Holocene in Iberia had to contend with rapidly changing environments climatic conditions. This constrained their economic resources capacity for demographic growth. The Atlantic façade was occupied throughout these times witnessed very significant environmental transformations. Archaeology offers a perspective on how past human population ecologies changed response this scenario. Archaeological radiocarbon data are used...

El Paleolítico Superior del Suroeste de la Península Ibérica está marcado por presencia conjuntos cantos tallados y lascas en cuarcita. La caracterización detallada a nivel regional cronológico estos es mayor importancia, ya que, las fases más recientes Paleolítico, se pueden encontrar sin asociación fósiles-guía o depósitos datables. En este estudio, hemos utilizado 36 cuarcita esa región para poner prueba el carácter diagnóstico esta materia prima través análisis tributos remontajes. Los...
