e analyzed the patterns of variation of haplogroup D1 in central Argentina, including new data and published information from other populations of South America. Almost 28% (107/388) of the individuals sampled in the region belong to haplogroup D1, whereas more than 52% of them correspond to the recently described subhaplogroup D1j (Bodner et al.: Genome Res 22 (2012) 811-820), defined by the presence of additional transitions at np T152C-C16242T-T16311C to the nodal D1 motif. This lineage was found at high frequencies across a wide territory with marked geographical-ecological differences. Additionally, 12 individuals present the mutation C16187T that defines the recently named subhaplogroup D1g (Bodner et al.: Genome Res 22 (2012) 811-820), previously described in populations of Patagonia and Tierra del Fuego. Based on our results and additional data already published, we postulate that the most likely origin of subhaplogroup D1j is the region of Sierras Pampeanas, which occupies th
