It is not necessary to understand what that means. Just look at the distribution of colors in Taiwan, and compare it to N and S China, elsewhere in northern Asia, and then to SE Asia. Which one does it resemble?
These caveats aside, it is our view that an early southern dispersal remains so far the best explanation for the genetic data, and we would like to emphasize that with more accurate dating of mtDNA and NRY haplogroups, additional autosomal DNA data, and with the simulation-based modeling approach advocated here, the early southern dispersal route may be expected to be supported and illuminated further, rather than contradicted. Indeed, the recent Pan-Asian SNP study found strong support for a largely southern origin of extant southeast and east Asian populations .Recall that pro-China types constantly assert that Taiwan's indigenous peoples came out of China, not out of the south.
