“…Since we do not find any root lineage of M31a1 or M32 in Myanmar populations, suggesting Myanmar unlikely being the source place of haplogroup M31 or M32. After re-analyzing additional 4180 mtDNAs from East Asia (Qian et al, 2001;Wen et al, 2004;Li et al, 2007;Gan et al, 2008;Zhao et al, 2009), mainland Southeast Asia (Black et al, 2006;Li et al, 2007;Irwin et al, 2008;Lertrit et al, 2008;Zimmermann et al, 2009;Peng et al, 2010) and Island Southeast Asia (Tajima et al, 2004;Hill et al, 2006Hill et al, , 2007, we did not observe any M31 or M32 mtDNA either, again substantiating our observation.…”
