<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->Chromosomes carrying the M9-G mutation are widely distributed across
Asia; however, chromosomes carrying the ancestral state at seven of the eight
downstream SNPs that mark immediate descendant lineages from M9 (K-M9*)
on the most recent Y-chromosome tree (Jobling and Tyler-Smith 2003) are found
at relatively high frequencies only in the Philippines, Indonesia, Melanesia,
Papua New Guinea, and Micronesia<b>. Capelli et al. (2001) hypothesized that all
Y chromosomes carrying the M9-G marker initially expanded out of Melanesia.</b>
If this is the case, the small proportion of K-M9* chromosomes (1.1%) in Bali
may be a signature of pre-Neolithic settlements. In contrast to M-P34 and
K-M230, the distribution of K-M9* chromosomes is not restricted to Oceania.
They are also present in Malaysia and the Near East, albeit at low frequencies.
