also known as Kensiu are a society of 250 hunter gatherers Eberhard et al 2019 who reside in the remaining arboreous hills of southern Thailand Kricheff and Lukas 2015 They are culturally classified as one of the Semang groups of Mainland Southeast Asia MSEA which include the Orang Semang indigenous cultural communities of Peninsular Malaysia such as the Batek Bateq Jehai Jahai Kintaq and Mendriq The Semang are loosely labeled together as the Negritos grouped with the other indigenous cultural communities of the region including the Andamanese e g Onge or Jarawa and the Philippine Negritos e g Ayta Agta or Mamanwa Barrows 1910 Radcliffe Brown 2013 This classification is mainly based on the early anthropological descriptions of the characteristic Negrito phenotype of these populations on average short stature frizzier hair and darker skin color Barrows 1910 Evans 1968 Radcliffe Brown 2013 The peopling of MSEA has been a to See full list on academic oup com Genetic Affiliation of the Maniq To determine the population genetic relationships of the Maniq we performed a PCA on populations of Africa Europe East Asia and Oceania fig 1B The Maniq individuals form a cluster close to the Malay Semang on a cline between the Andamanese and East Asian population clusters indicating an admixture between Andamanese related and East Asian related ancestral sources We then performed a PCA restricted to Asian and Oceanian populations fig 1C Eigenvector 1 spans from East Asian to Maniq Exhibit High Degree of Genetic Differentiation To determine the degree of genetic differentiation in Maniq in relation to other populations in the Asia Pacific region we estimated the in between population FST of our data set panel supplementary figs 1 3 Supplementary Material online We find that the Maniq have experienced intense genetic drift given that they exhibit very high genetic distance based on pairwise FST when compared with any other reference population The degree of genetic drift in Maniq is even higher than that of A Maniq Are One of the Hòabìnhian Related Populations of MSEA It was previously argued that the ancient hunter gatherers of the Hòabìnhian cultural complex are regarded as the ancestors of present day hunter gatherers of MSEA McColl et al 2018 This was recently supported by an ancient DNA data where among the ancient individuals Onge and Jarawa were shown to be most genetically affiliated with an 8 000 year old Hòabìnhian individual from Pha Faen Laos and a 4 000 year old Hòabìnhian individual from Gua Cha Malaysia McColl et al 2018 Using th See full list on academic oup com We present in this study the first comprehensive investigation on the genetic origins and ancestry of the Maniq of Thailand who are considered as one of the last remaining primary hunter gatherers in the region Kelly 2013 Our genome wide analyses reveal that the Maniq population form a clade with the Semang groups of MSEA who altogether carry high levels of Andamanese related genetic ancestry Among the Semang the Maniq cluster more closely to the Bateq and the Kintaq than to Jehai and Mendriq fig 6 and supplementary fig 12 Supplementary Material online This is in line with the earlier anthropological descriptions of the Maniq Brandt 1961 where they were regarded to share common cultural features with the Semang groups of Peninsular Malaysia indicating a shared history and origins Both the Maniq and the Malay Semang do trade their goods with other non Semang groups of MSEA In addition they also speak a language that is altogether classified under the Aslian branc

University Ethics Committee for Human Research Reference No HE622223 All study participants self identify as belonging to the Maniq and are at least 18 years old Consent process was conducted through a series of consultations where the aims and rationale of the study were thoroughly explained and discussed with the Maniq Saliva samples were collected from each individual Quality Control and Data Preparation The newly generated genotyped data were processed for quality check and filtering using the PLINK v1 9 software Purcell et al 2007 Duplicate samples duplicated SNPs and mitochondrial and sex chromosomal SNPs were removed All SNPs with a high missing rate geno 0 001 as well as all SNPs which failed the Hardy Weinberg Exact test P 10 6 were excluded No sample had to be excluded because of high missing call rates mind 0 01 We used the R program version 4 0 3 R Core Team 2013 Population Genetic Analysis Runs of homozygosity ROH and inbreeding coefficient were estimated using the homozyg and het flags of PLINK v1 9 respectively The number of ROH for each trach length category for each population was plotted to infer demographic history Ceballos et al 2018 where long tracts of ROH are characteristic of genetic drift caused by recent bottlenecks founder events or endogamy Principal component analysis PCA and estimation of between population FST were performed using EIGENSOFT
