Abstract
[Resumen] En este trabajo se presentan los primeros resultados de un estudio de paleogenética realizado en
los restos óseos de Elba, la mujer mesolítica de Chan do Lindeiro (Pedrafita do Cebreiro, Lugo). El
estudio se realizó a nivel de ADN mitocondrial completo y de marcadores nucleares relacionados
con rasgos fenotípicos, como pigmentación y tolerancia a la lactosa. El método se basa en el
enriquecimiento mediante captura por hibridación de ADN mitocondrial y genómico, seguido de
secuenciación de alto rendimiento. La cobertura obtenida para los marcadores genómicos resultó
insuficiente, pero el genoma mitocondrial se recuperó en un 99%. La mujer de Chan do Lindeiro
pertenece al haplogrupo U, característico de los cazadores recolectores europeos, y dentro de éste, en
el subhaplotipo U5b1, cuyo origen se sitúa en la Península Ibérica hace unos 16-20000 años.
[Abstract] In this work the first results of a paleogenetic study are presented in the bone remains of Elba, the mesolithic woman of Chan do Lindeiro (Pedrafita do Cebreiro, Lugo). The study was performed at the level of complete mitochondrial DNA and of nuclear markers related to phenotypic traits, such as pigmentation and lactose tolerance. The method is based on enrichment by hybridization capture of mitochondrial and genomic DNA, followed by high throughput sequencing. The coverage obtained for the genomic markers was insufficient, but the mitochondrial genome was recovered by 99%. The Chan do Lindeiro woman belongs to the haplogroup U, characteristic of the European hunter gatherers and within this, in the subhaplotype U5b1, whose origin is located in the Iberian Peninsula some 16-20000 years ago.
