The genetic origins of the Andaman Islanders (original) (raw)
2003, The American Journal of …
Mitochondrial sequences were retrieved from museum specimens of the enigmatic Andaman Islanders to analyze their evolutionary history. D-loop and protein-coding data reveal that phenotypic similarities with African pygmoid groups are convergent. Genetic and epigenetic data are interpreted as favoring the long-term isolation of the Andamanese, extensive population substructure, and/or two temporally distinct settlements. An early colonization featured populations bearing mtDNA lineage M2, and this lineage is hypothesized to represent the phylogenetic signal of an early southern movement of humans through Asia. The results demonstrate that Victorian anthropological collections can be used to study extinct, or seriously admixed populations, to provide new data about early human origins.

ABSTARCT: Our complete sequencing of 220 mtDNA genomes from the Savara and Porja of east coastal India reveals about 25 per cent genomes belongs to European macro haplogroup N. For the first time we identified mitochondrial DNA from one south Indian Savara individual that shares seven specific mutations with the N22 lineage observed in the Orang Asli group of Aboriginal Malaya, Cuyonin from Palawan and one single mutation sharing with Mindanao of Philippines which forms N22b sub-lineage. The coalescence time of N22 lineage is 20,600 ± 7000 kybp shifts the focus of " Two layer " hypothesis of human settlement in ISEA.
