As suggested by their cultural ties, the Maniq appeared to be most closely related to the Semang groups in Malaysia, indicating a recent shared history. Comparisons with other modern groups showed that the Maniq and Malay Semang populations shared
alleles with indigenous Papuans and Andamanese, indicating “deep historical relationships among these populations,” according to the study’s authors.
The study also revealed that the Maniq exhibited similarities to ancient DNA samples associated with the Hòabìnhian, a cultural complex of ancient hunter-gatherers thought to be the ancestors of present-day hunter-gatherers in mainland Southeast Asia.
In the past, Hòabìnhian-related populations were more widespread, with descendants found in Laos, southern China, and even as far as Japan. According to the study’s authors, however, “due to the recent expansion of East Asian-related groups, the Hò
abìnhian-related cultural communities were either displaced, replaced, or absorbed into the larger population of farmer migrants.” The study reveals that this was not the case with the Maniq, who remained largely isolated and retained their hunter-
gatherer lifestyle, “making them one of the few groups in mainland Asia carrying high levels of Hòabìnhian-related ancestry.”
The most striking finding of the study was the high degree of genetic differentiation exhibited by the Maniq, which was higher than what has been observed for the Mangyan Buhid of the Philippines and comparable to that of the Surui of Brazil, suggesting
that the Maniq are more genetically differentiated than virtually any other known human population worldwide.
Note: I visited a Semang camp in Malaya in 1982.
Note: the photo shows pole beds, which are also used by pygmy people in the Ituri rainforest.
Note: the Maniq are called Sakai in Malay.
