Haplogroup E
Possible time of origin 16,400 to 39,000 YBP [1]
Possible place of origin Indonesia[1] or Taiwan[2]
Ancestor M9

In human mitochondrial genetics, haplogroup E is a human mitochondrial DNA (mtDNA) haplogroup typical for the Malay Archipelago. It is a subgroup of haplogroup M9.

[edit] Origin

After a point of view, it was arisen in Northeast Sundaland or around Sulawesi and Sulu Seas.[1] On the other hand, it might be related with the Austronesian languages expansion from Taiwan to Insulinde, indicating a common origin of the populations of insular Southeast Asia and suggesting a prevalence in the Taiwanese aboriginal gene pool (mainly E with B4, B5a, F1a, F3b and M7) of its initial late Pleistocene settlers.[2]

[edit] Distribution

Haplogroup E has a Southeast Asian distribution. Until now it has been detected in the Malay peninsula populations and in the Sabah of Borneo; and it is also present in coastal Papua New Guinea as well as in Taiwan, in the Philippines, and in some Pacific islands such as Guam.
