“…Specifically, they have identified the A2ah lineage in the Andean area, even within a pre-Hispanic individual. The implications of this discovery are profound, raising intriguing questions about the potential gene flow between the Andean and lowland regions before the Spanish arrival [95].…”

This article presents a comprehensive genetic study focused on pre-Hispanic individuals who inhabited the Aburrá Valley in Antioquia, Colombia, between the tenth and seventeenth centuries AD. Employing a genetic approach, the study analyzed maternal lineages using DNA samples obtained from skeletal remains. The results illuminate a remarkable degree of biological diversity within these populations and provide insights into their genetic connections with other ancient and indigenous groups across the American continent. The findings strongly support the widely accepted hypothesis that the migration of the first American settlers occurred through Beringia, a land bridge connecting Siberia to North America during the last Ice Age. Subsequently, these early settlers journeyed southward, crossing the North American ice cap. Of particular note, the study unveils the presence of ancestral lineages from Asian populations, which played a pivotal role in populating the Americas. The implications of these results extend beyond delineating migratory routes and settlement patterns of ancient populations. They also enrich our understanding of the genetic diversity inherent in indigenous populations of the region. By revealing the genetic heritage of pre-Hispanic individuals from the Aburrá Valley, this study offers valuable insights into the history of human migration and settlement in the Americas. Furthermore, it enhances our comprehension of the intricate genetic tapestry that characterizes indigenous communities in the area.

“…Examples include American black bear ( Ursus americanus ), brown bear ( U. arctos ), Pacific marten ( Martes caurina ), Haida ermine ( Mustela haidarum ) and several small mammals (Byun et al, 1997; Colella et al, 2018, 2021; Cook et al, 2006; Dawson et al, 2014; Hope et al, 2016; Jackson & Cook, 2019; Puckett et al, 2015; Sawyer et al, 2019; Talbot & Shields, 1996; Wooding & Ward, 1997). Extensive paleontological work in the Alexander Archipelago recovered thousands of mammalian remains from multiple caves, including human remains and artefacts (Aqil et al, 2023; Dixon, 2015; Lindo et al, 2017), and some of the oldest New World dog remains (da Silva Coelho et al, 2021). The Shuká Káa (On Your Knees) Cave on Prince of Wales Island is so far the only cave with a preglacial record with specimens radiocarbon dated to more than 45 ka (Heaton & Grady, 2003), while radiocarbon‐dated subfossils from all other caves have been of postglacial age.…”

During the Late Pleistocene, the Laurentide and Cordilleran Ice Sheets periodically covered much of North America, including portions of, or perhaps the entire, Alexander Archipelago located in Southeast (SE) Alaska. While the Laurentide Ice Sheet was at its maximum extent during the global last glacial maximum (LGM), a period that spanned ~26-19 thousand years ago (ka;Clark et al., 2009), the Pacific margin of the Cordilleran Ice Sheet only reached its greatest

Ancient DNA (aDNA) has added a wealth of information about our species’ history, including insights on genetic origins, migrations and gene flow, genetic admixture, and health and disease. Much early work has focused on continental-level questions, leaving many regional questions, especially those relevant to the Global South, comparatively underexplored. A few success stories of aDNA studies from smaller laboratories involve more local aspects of human histories and health in the Americas, Africa, Asia, and Oceania. In this Review, we cover some of these contributions by synthesizing finer-scale questions of importance to the archaeogenetics field, as well as to Indigenous and Descendant communities. We further highlight the potential of aDNA to uncover past histories in regions where colonialism has neglected the oral histories of oppressed peoples.
