The phylogeography of the rare Native American haplogroups D4h3a and X2a, when evaluated at the level of complete mitochondrial genomes, indicates that at least two migration routes from Beringia were used at approximately the same time by the Paleo-Indians. The Pacific coastal path probably playe...
1. Two subhaplogroups, H1 and H2, were quite frequent (>5%), while H3 had a frequency of 0.54%, comparable to previous estimates [13, 32]. Fig. 1 Map of Romania showing the approximate migration routes and the mtDNA haplogroup distribution in the Romanian provinces. The map depicts the...
(2002) have also identified the signature of a probable ancient migration from Asia into north Cameroon, in the form of a derived form of haplogroup R. This clade is not found in present-day western Eurasia or anywhere else in Africa, with the likely exception of Egypt (at 13%; see ...
This point of view is compatible with the attrib- uted date for the origin of the mutation that defines haplogroup V (4577 NlaIII), but it does not need to resort to migrationist models to explain this mutation's distribution in Indo-European populations. Acknowledgments This work was ...

and F3b(1) (0.3%) have been associated with this migration [24,28,30,80]. Thus, 27.1% (our sample: 29.6%) of the East Timor mtDNAs could be related to this dispersal. A ~20% contribution for ISEA was previously estimated [24]. The OOT-related mtDNA haplogroups (as of published ...
Distinct, partly competing, “waves” have been proposed to explain human migration in(to) today’s Island Southeast Asia and Australia based on genetic (and other) evidence. The paucity of high quality and high resolution data has impeded insights so fa
In contrast to haplogroup M, ancient sub-clades of haplogroup N are spread both east and west of India as well as within India itself. Several migration scenarios involving multiple "out of Africa" events punctuated by space, time or both, could be invoked to explain the phylogeography of the...
induced by the reduced population size since peopling occurred, has led to a very atypical distribution of haplogroups/haplotypes in this group of islands.We cannot ignore the influence of biodemographic and genetic processes, namely founder effect, genetic drift, migration, and even recent mutational...
Although the small population size of the Parsis (a few thousand) may have distorted haplogroup frequencies in this population, diversity of both Y-chromosome and mtDNA lineages remains high, making a strong drift effect unlikely. Our results therefore support a male-mediated migration of the ...
