Primer genoma mitocondrial en restos humanos de la Costa de Santa Cruz, Argentina

Abstract: RESUMENEn este trabajo se presenta la secuencia completa de ADN mitocondrial, obtenida a partir de restos óseos de un hombre adulto, hallado en el sitio Cañadón Misioneros (provincia de Santa Cruz, Argentina), con una antigüedad de 70 ± 30 años antes del presente. La secuencia corresponde al haplogrupo (hg) D4h3a5, nativo de América y exclusivo del sur de Patagonia, donde ha sido descripto tanto en muestras antiguas como actuales. Esta secuencia constituye el primer dato de ADN mitocondrial en la costa atlánti… Show more

“…Our analysis revealed a higher diversity of mitochondrial haplotypes and a different distribution of haplogroup frequencies in the Early to Middle Holocene Pampas compared to other published Middle to Late Holocene pre-Columbian Eastern Patagonian and SCSA populations ( Cabana et al., 2006 ; Marrero et al., 2007 ; García and Demarchi, 2009 ; Bobillo et al., 2010 ; Nores and Demarchi, 2011 ; de Saint Pierre et al., 2012b ; Motti, 2012 ; Cardoso et al., 2013 ; de la Fuente et al., 2015 ; Crespo et al., 2017 ; Arencibia et al., 2019 ; Motti et al., 2020 ; Postillone et al, 2020a , 2020b ) ( Table S2 ). These include Late Holocene groups from the geographically near site of Paso Alsina 1, at the eastern Pampa-Patagonia transition ( Postillone et al., 2020b ), and other sites along the Atlantic coast of Argentinian Patagonia ( Motti et al., 2015 ; Crespo et al., 2017 ). The difference in haplogroup frequencies between our data set and those previously published is driven by the predominance of haplogroup C1 and the presence of B2b in the Early to Middle Holocene Pampas, while haplogroup D1 is predominant and B2 is mostly absent in the Middle to Late Holocene pre-Columbian Eastern Patagonian and SCSA populations.…”

“…(2020b) have proposed that D1j probably migrated from central Argentina. This hypothesis was based on the D1j geographic distribution, which extended along the Patagonian Atlantic coast in the Late Holocene groups ( Motti et al., 2015 ; Crespo et al., 2017 ; Postillone et al., 2020b ), and is presently more frequent in the Eastern Pampas, while absent in western Patagonia and the extreme South ( Bodner et al., 2012 ; García et al., 2012 ). The Early Holocene D1j mitogenome in Laguna de los Pampas is basal in the D1j phylogeny and supports the hypothesis that D1j spread from the Pampas.…”

“…El linaje D4h3a (Fig. 5) fue hallado solo en un individuo de la población del Lago Salitroso, cuyo haplotipo es compartido con un individuo Selk'nam antiguo (D4h3a+16051; Raghavan et al, 2015), dos individuos de la costa de Santa Cruz antiguos (Crespo et al, 2017a;Motti et al, 2015), y Tehuelches actuales (de Saint Pierre et al, 2012a).…”

“…Finalmente, un solo individuo fue asignado al haplogrupo pan-americano D4h3a, por lo que no fue incluido en el análisis filogeográfico. Este linaje se encuentra mayormente distribuido en la zona oeste del continente americano, desde Alaska hasta Tierra del Fuego, en poblaciones nativas de Ecuador, norte de México, Chile, sudeste de Brasil y Perú (Richards et al, 1999;Moraga et al, 2000;Alves Silva et al, 2000;Perego et al, 2010;Motti et al, 2015). Por otra parte, las frecuencias más elevadas de este linaje se encuentran en poblaciones Cayapa y Tehuelches, con un porcentaje del 25% del total de las muestras asignadas a un linaje nativo americano (Bravi, 2004).…”
