Resumen:
For the first time, we could identify a novel Native American founding lineage C-M217 (C3*)
within a restricted area of North-west South America. This finding is intriguing in view of the high
prevalence of the same haplogroup in Central, East and North East Asia, and its concurrent
absence from North America. Possible scenarios include (i) later migratory waves that quickly
passed the existing populations in North America, and (ii) long-distance trade or contact with East
Asia. Fifty years after Estrada, Meggers and Evans (1962) suggested trans-Pacific connections
between the middle Jōmon culture of Kyushu (Japan) and the littoral Valdivia culture in Ecuador
(6400-5300 YBP), based upon cultural similarity, it is indeed tempting to speculate that C-M217
(C3*) was introduced into South America from Eastern Asia by sea, either along the American
West coast or across the Pacific (with some help by major currents). The striking differences
observed between the Y-STR haplotypes of Ecuadorian and Asian C-M217 (C3*) carriers would
be explicable in terms of a long divergence time after the arrival (although a more recent
introduction cannot be excluded).
