The authors provide an initial report on possibly the southernmost expansion of humans in pre-industrial times. The archaeological site, in the Cape Horn archipelago, consists of a campfire site, fragments of a weapon, and butchered bones. Radiocarbon dating places the site c. 260-460 years BP.

The historic, ethnographic and archaeological information on the Elizabeth Island, Strait of Magellan, Chile is presented, with an emphasis on the location of the island on the eastern limit of the distribution of patagonian and fuegian maritime hunter-gatherers. Taphonomic and formational observations were also made. The diversity of archaeological materials recorded on the island is highlighted, including elements attributable to both maritime and terrestrial hunter-gatherers. Finally, the place of the island within the cultural geography of the region is considered, discussing its relationships with other islands of the Magellan Strait and the continent.

Studies of the peopling of the Americas have focused on the timing and number of initial migrations. Less attention has been paid to the subsequent spread of people within the Americas. We sequenced 15 ancient human genomes spanning from Alaska to Patagonia; six are >= 10,000 years old (up to similar to 18x coverage). All are most closely related to Native Americans, including those from an Ancient Beringian individual and two morphologically distinct "Paleoamericans." We found evidence of rapid dispersal and early diversification that included previously unknown groups as people moved south. This resulted in multiple independent, geographically uneven migrations, including one that provides clues of a Late Pleistocene Australasian genetic signal, as well as a later Mesoamerican-related expansion. These led to complex and dynamic population histories from North to South America.

ASSESSMENT OF AN EAST-WEST PHENOTYPIC VARIATION IN BODY HEIGHT, BODY FORM AND BODY MASS AMONG PREHISTORIC HUNTER-GATHERERS OF PATAGONIA AND TIERRA DEL FUEGO, CHILE

Fuego-Patagonia's marine and terrestrial groups were historically described as phenotypically distinct but, studies of these phenotypic differences have yet to be conducted. This study evaluates phenotypic variation in Fuego-Patagonia. Phenotypic disparities result from extrinsic and intrinsic factors and therefore can reveal differences in both long and short term adaptations as well as genetic differences. Fifty-one adults were assessed. A total of six post-cranial measurements were included: maximum length of the humerus (MHL); maximum length of the radius (MRL); Bicondylar length of the femur (BFL); Maximum length of the tibia (MTL); bi-iliac breadth (BIB), and; antero-posterior diameter of the femoral head (FHD). Brachial index, crural index, body mass, body mass index and stature were then calculated. In general, terrestrial individuals had longer lower limb bones and were the tallest and heaviest. Marine individuals had the shortest bones and were shorter and lighter. Mixed-economy individuals showed mostly intermediate values. The trends are more marked in males than in females. The results suggests the presence of an east-to-west phenotypic gradient in the region that may have resulted from intrinsic and/or extrinsic differences between the groups. But, the sample size of this study is small, and thus the results should be cautiously considered.

Protocol, Potentials, and Limitations of Ancient Teeth 3D Printing

Bioarchaeological analyses of teeth rely traditionally on noninvasive methods that reveal essential information about past individuals and populations. Methodological developments have revolutionized the discipline, but their application is commonly invasive and destructive. The resulting loss of material and information can be buffered through 3D technology applications. Although useful, it is essential that we carefully assess the reliability of these methods, in order to understand what data are preserved and which ones are lost through their application. This study offers a protocol for the implementation of 3D technology in the fabrication of ancient teeth analogs. Analog accuracy was assessed by comparing metric and non-metric traits between the originals and their respective analogs. Results showed that metric traits preserved well, but the preservation of non-metric traits was partially hindered.

Objectives: This study aims to characterize the genetic histories of ancient hunter-gatherer groups in Fuego-Patagonia (Chile) with distinct Marine, Terrestrial, and Mixed Economy subsistence strategies. Mitochondrial (mtDNA) and Y-chromosome data were generated to test three hypotheses. H-0: All individuals were drawn from the same panmictic population; H-1: Terrestrial groups first populated the region and gave rise to highly specialized Marine groups by similar to 7,500 cal BP; or H-2: Marine and Terrestrial groups represent distinct ancestral lineages who migrated independently into the region. Methods: Ancient DNA was extracted from the teeth of 50 Fuegian-Patagonian individuals dating from 6,895 cal BP to after European arrival, and analyzed alongside other individuals from previous studies. Individuals were assigned to Marine, Terrestrial, and Mixed Economy groups based on archeological context and stable isotope diet inferences, and mtDNA (HVR1/2) and Y-chromosome variation was analyzed. Results: Endogenous aDNA was obtained from 49/50 (98%) individuals. Haplotype diversities, F-ST comparisons, and exact tests of population differentiation showed that Marine groups were significantly different from Terrestrial groups based on mtDNA (p < 0.05). No statistically significant differences were found between Terrestrial and Mixed Economy groups. Demographic simulations support models in which Marine groups diverged from the others by similar to 14,000 cal BP. Y-chromosome results showed similar patterns but were not statistically significant due to small sample sizes and allelic dropout. Discussion: These results support the hypothesis that Marine and Terrestrial economic groups represent distinct ancestral lineages who diverged during the time populations were expanding in the Americas, and may represent independent migrations into Fuego-Patagonia.
