The timing for the evolution of capacity to inscribe landscape with rock art has global relevance. While this was an in-built when Homo sapiens first colonized Americas, heterogeneous distribution shows that it a facultative behavior arising under unknown socioecological conditions. Patagonia last region be explored by humans. its is globally important, remains largely undated absolute methods. We report earliest set directly radiocarbon-dated motifs from archaeological site Cueva Huenul 1...

The relations between humans and animals extend into socio-cultural aspects that go beyond the mere acquisition of food, meaning constitute cultural resources fulfill diverse roles in social systems. Visual images different media, including rock art, represent one ways which these complex relationships take place.

The high Andes of western South America feature extreme ecological conditions that impose important physiological constraints on humans including high-elevation hypoxia and cold stress. This leads to questions regarding how these environments were colonized by the first waves reached them during late Pleistocene. Based previous research, aided human behavioral ecology principles, we assess hunter-gatherer strategies in Andean highlands Pleistocene early Holocene. Specifically, formulate...

Abstract This work concerns the study of colors and dyes identified on archaeological textiles from Atacama Desert. The different garments ornaments come excavation two important pre-Columbian cemeteries Tarapacá region: Tarapacá-40 attributed to Formative period (1100 BC–660 AD) Pica-8 Late Intermediate (900–1450 AD). For first time, a multi-analytical approach with non-invasive techniques using FORS SERS was applied samples less than 2 cm length for physicochemical characterization raw...
