“…1A and fig. S4), we observe that the Copan individuals form a distinct cluster, closely located to clusters of Late Archaic genomes from Belize (25)and pre-Hispanic genomes from Panama (26). Within the Copan, some individuals exhibit a slight shift toward present-day Maya individuals, indicating a potential genetic link between ancient and modern individuals associated with Maya culture.…”

Copan was a major capital at the southeasternmost of the Maya civilization, serving as a crossroads connecting Central and South America. In 426/427 CE, the city witnessed the establishment of a royal dynasty, which endured for approximately 400 years. Despite extensive historical and archaeological records, there remains limited information regarding the genetic origins of people who resided in Copan. Here, we present seven Classic Copan genomes including an enigmatic dynastic ruler and his sacrificed companion. Our analysis identifies a high genetic affinity of the Classic Copan with present-day Maya. Both groups exhibit an admixture of Mesoamerican and South American Farmer (SAF) ancestry, with a shift in a dominant component from SAF to Mesoamerican. At the individual level, commoners show a more prominent SAF ancestry, while the royal individual demonstrates nearly equal contributions from two ancestors. These results highlight a dual ancestral structure in this geographic extreme of the Classic Maya state, uncovering a cline of Mesoamerican ancestry across individuals.

“…Considering the evidence from genome-wide data, ancient and presentday individuals from Patagonia are part of the major South Native American (SNA) lineage, first characterised in Anzick-1 individual from Montana (USA) and linked to the Clovis archaeological culture [69][70][71]75,76,94]. Several SNA lineages have been described so far, and the links among them and their relative contributions into the different regions of South America remain to be disentangled [70,71,95,96]. The evidence of a putative replacement across South America of a first lineage (SNA1) associated with Anzick-1 by later migration waves [71] is challenged as new genomes are generated and new demographic models are suggested [96,97].…”

“…Later migration waves (i.e., not related to SNA1), have been assigned to SNA2 lineage, associated with individuals linked to the Western Stemmed Tradition [98]. However, the term SNA2 is used to describe lineages that have different origins (e.g., see the models reported in [95,96]). These pulses of population influx appear to have a heterogeneous genetic legacy across the subcontinent [70,71,95], and their importance in the demographic history of Patagonia remains unclear.…”

Patagonia is a region that has fascinated researchers for centuries considering the evidence of early human occupation, its geographical and environmental variability, and the diversity of human adaptations. From an archaeological and bioanthropological perspective, the region has been the focus of many studies addressing a wide range of questions, from a broad scale, such as the peopling of the Americas, to a local scale concerning the diversity and interactions of human populations. For three decades, paleogenetic studies have contributed to the understanding of population dynamics in the region: first using uniparental markers, particularly mitochondrial DNA in a much larger proportion; and more recently including genome-wide data for ancient individuals. In this work, we revise these studies considering three themes: (1) the first stages of migration into the region; (2) the diversification and interactions of populations during the Middle and Late Holocene; and (3) the link between present-day and ancient populations. While genetic evidence from the early peopling stages is either absent or scarce, making it difficult to evaluate the relative contributions of early South American lineages in the first Patagonian populations, evidence from later periods (from Middle Holocene onwards) is consistent with a single migration wave with founding events and genetic drift acting on small groups during their migration southward. After the initial occupation, the population dynamics seem to have been characterised by the relative isolation of different groups, leading to their differentiation. While there is evidence of some degree of gene flow between groups, the genetic structure in the region is generally associated with geography, subsistence systems, and languages. After European contact, paleogenetic data supports a relative genetic continuity in the region. We finish this review with a fourth theme in which we reflect on the current state and direction of the field in Patagonia, highlighting research lines that will benefit from the implementation of state-of-the-art paleogenomic approach, as well as legal and ethical considerations that would allow to move forward into a more collaborative and inclusive field.
