“…Por un lado, que efectivamente estos restos pertenezcan a un cánido doméstico, cuya depositación en contextos fúnebres ha constituido una práctica habitual (Byrd et al 2013;Berón et al 2015). La historia evolutiva y la fuerte hibridación de los carnívoros hacen dificultosas las identificaciones zooarqueológicas basadas en la comparación morfológica (Guiry 2012;Byrd et al 2013;Popović et al 2020). Por otra parte, puede plantearse que este patrón, comúnmente observado entre perros domésticos, también se haya dado con carnívoros silvestres.…”

“…Por otra parte, puede plantearse que este patrón, comúnmente observado entre perros domésticos, también se haya dado con carnívoros silvestres. En esta línea, un reciente estudio molecular sobre restos registrados en Bolivia reclasificó especímenes previamente identificados como perro doméstico y los asignó a L. culpaeus (Popović et al 2020). Según Prevosti et al (2011), el cánido Dusicyon avus se habría extinguido en algún momento entre los ca.…”

Este trabajo tiene como objetivo caracterizar el sitio Cañada Seca-1, un entierro múltiple (NMI=24) localizado en el valle del Atuel y fechado en ca. 1500 años AP, a través de la integración de diferentes líneas de evidencia. A partir de este registro se discuten las interpretaciones en torno a la presencia de cultígenos y sus implicancias para la subsistencia humana en un área caracterizada tradicionalmente como el límite de la dispersión agrícola sudamericana, ca. 2200 años AP. Los resultados destacan que los individuos inhumados en el sitio no habrían desarrollado una estrategia fundamentalmente agrícola, aunque el maíz formó parte de su dieta. Además, la nueva información sobre los comportamientos mortuorios en la zona del valle del Atuel, ofrece evidencias tanto sobre movilidad como sobre el uso de tecnologías utilitarias (líticas) y no utilitarias (ornamentos líticos y malacológicos) que trascendieron la vida cotidiana y los acompañaron en la muerte.

“…Whether dogs colonized North America with the earliest humans or only later, they spread broadly around the continent. Archaeological evidence shows that dogs were present at different mid-continental sites approximately 10 000 years ago [ 13 ], spanning from Newfoundland to Alabama and California by 4000 years ago, and into South America by 1000 years ago [ 9 , 11 , 23 ].…”

An early dog from southeast Alaska supports a coastal route for the first dog migration into the Americas

The oldest confirmed remains of domestic dogs in North America are from mid-continent archaeological sites dated approximately 9900 calibrated years before present (cal BP). Although this date suggests that dogs may not have arrived alongside the first Native Americans, the timing and routes for the entrance of New World dogs remain uncertain. Here, we present a complete mitochondrial genome of a dog from southeast Alaska, dated to 10 150 ± 260 cal BP. We compared this high-coverage genome with data from modern dog breeds, historical Arctic dogs and American precontact dogs (PCDs) from before European arrival. Our analyses demonstrate that the ancient dog belongs to the PCD lineage, which diverged from Siberian dogs around 16 700 years ago. This timing roughly coincides with the minimum suggested date for the opening of the North Pacific coastal (NPC) route along the Cordilleran Ice Sheet and genetic evidence for the initial peopling of the Americas. This ancient southeast Alaskan dog occupies an early branching position within the PCD clade, indicating it represents a close relative of the earliest PCDs that were brought alongside people migrating from eastern Beringia southward along the NPC to the rest of the Americas. The stable isotope δ 13 C value of this early dog indicates a marine diet, different from the younger mid-continent PCDs' terrestrial diet. Although PCDs were largely replaced by modern European dog breeds, our results indicate that their population decline started approximately 2000 years BP, coinciding with the expansion of Inuit peoples, who are associated with traditional sled-dog culture. Our findings suggest that dogs formed part of the initial human habitation of the New World, and provide insights into their replacement by both Arctic and European lineages.

“…American dog populations today may or may not have a strong genetic component originating from pre-Hispanic dogs, as well as from wild canids from the genus Canis. Revisionary work based on ancient DNA, radiocarbon dating (Frantz et al 2020 ;Popović et al 2020), and morphology (Manin & Evin 2020), is likely to contradict many previous attributions of materials to domestic dogs or claims of hybridizations with local canids. Even for well-known species such as the dog, many uncertainties remain regarding important topics, such as migratory routes of humans and dogs in the Americas, and dog dispersal following Indigenous peoples' social networks, historical cultural contexts, local hybridizations, quantification of dog morphological diversity (past and present), and phylogenetic relationships of current American breeds.…”
