Genetic legacy of the Paleolithic black Asians – the Moros of Asia

Genetic legacy of the Paleolithic black Asians

The migration history of haplogroup D-M174 is most
mysterious. By now, we have known little about the
origin and dispersal of this haplogroup. This haplo-
group was derived from African haplogroup DE-M1
(YAP insertion) and is associated with a short black
Asian physical style. Haplogroups E and D are brother
haplogroups. While haplogroup E was carried westwards
to Africa by the tall black people, haplogroup D might
have been carried eastwards to East Asia by the short
black people. Haplogroup D-M174 has high
frequencies in the Andaman Negritos, the northern
Tibeto-Burman populations and the Ainu of Japan,
and also appears at low frequencies in other East
and Southeast Asian and Central Asian populations.

The paragroup D* is restricted to the Andaman Islands,
which has been isolated for at least 20 thousand years.
Some other minor haplogroups, also included in D*, can
be found around Tibet. Most of the populations with
haplogroup D have very dark skin color, including the
Andamanese, some of the Tibeto-Burman and Mon-Khmer
people and the Ainu people. Some Ainus may have
developed pale skin to absorb more ultraviolet light
in high latitude regions.
