The journey taken by our male ancestors can also be understood in a similar way to
the tracing of our female ancestors through mtDNA. The male haplotype is determined
by Short Tandem Repeats (STR). This method can produce a phylogenetic tree of
Y-chromosomes which can be divided into haplogroups A and B which spread solely in
Africa. Haplogroup A branched out as E and F, both of which eventually went out of Africa.
However, haplogroup E stayed in Africa. Haplogroup E is called the African haplogroup
while the ones which moved out are called non-African. Haplogroup E migrated to the north
and gave rise to many branches of other haplotypes. Meanwhile haplogroup F followed
the southern migratory route along the coastal areas, travelling through Indonesia and
ending finally in Australia. The haplogroups that eventually spread to all places around the
Earth were offshoots or combinations of these E and F groups. For example, E formed D
and C. Then, C migrated from Asia to America. Meanwhile D formed O, which then went
south to Indonesia (Figure 3). Recent research allows a more detailed analysis of each of
the Y-chromosome haplogroups. In each of these haplogroups, there are sub-haplogroups
such as CR which consists of three sub-branches C, DE (consists of D and E), and F. These
are African and non-African haplogroups. Using a structural analysis, it was found that
Africa and Asia shared haplogroup DE and non-African haplogroup C dispersed in East Asia,
Oceania, and America. Other globally distributed non-African groups include F-M89 with
its branch haplogroup K. These sub-haplogroups F and K provide proof of regionalization.
Haplogroup F* and H are only found in Asia, while the geographical center of haplogroup
