A new genetic study has been published in the PLOS Genetics journal. They
studied the Y chromosome markers in 50 tribal South American populations.
They found evidence of several migrations to the Americas. 1,011 subjects
were studied. Among other finds, they identified a lineage never described
in North and Central America before; the C-M217 (C3*) haplotype, which is
frequent in East, Central and Northeast Asia, but not in Alaska or Central
America. It was found in Ecuador and would be consisted with entry from a
trans-Pacific or coastal route. This haplotype is found in Korea, Japan and
among the Ainu of northern Japan and Melanesia.They also found a Polynesian
lineage in Peru. (Sender's note; this is consistent with findings from Kennewick
Man and Monte Verde).
It has been observed that very ancient pottery in the Americas produced by
the Valdivia Culture of Ecuador at 4,400 BCE is very similar to the middle
Jomon culture of Japan at the same time. A trans-Pacific contact has been
hypothesized here. The fact that this new research finds the new lineage of
C3 in Ecuador in the same area may strengthen that theory.
