Article Synopsis
- The study investigates how migration affected genetic diversity in populations during the settlement of the Southern Cone by analyzing complete mitochondrial genomes from two archaeological samples in southern Patagonia.
- The researchers sequenced the mitogenomes of two late Holocene individuals and performed phylogenetic analyses to understand their genetic relationships to other populations.
- Findings indicated significant genetic divergence and connections to other regions, revealing that the settlement dynamics in southern South America are more intricate than previously understood.
Objectives: The timing and duration of breastfeeding and weaning in past hunter-gatherer populations are discussed based on the results of stable carbon and nitrogen isotope analyses undertaken on a Late Holocene skeletal sample from Lake Salitroso in the Patagonian steppe (Argentina). Research in Lake Salitroso is part of a regional project that studies the relationship between hunter-gatherer societies, their organizational systems and the environmental changes during the last 3,000 years in Patagonia.
Methods: The sample included 52 individuals: 33 subadults and 19 adults of both sexes.
The aim of this study was to examine the parasite remains present in rodent coprolites collected from the archaeological site Alero Destacamento Guardaparque (ADG) located in the Perito Moreno National Park (Santa Cruz Province, 47 degrees 57'S 72 degrees 05'W). Forty-eight coprolites were obtained from the layers 7, 6 and 5 of ADG, dated at 6,700 +/- 70, 4,900 +/- 70 and 3,440 +/- 70 years BP, respectively. The faecal samples were processed and examined using paleoparasitological procedures.
