Abstract The Austronesian expansion, one of the last major human migrations, influenced regions as distant tropical Asia, Remote Oceania and Madagascar, off east coast Africa. identity Asian groups that settled Madagascar is particularly mysterious. While language connects to Ma’anyan southern Borneo, haploid genetic data are more ambiguous. Here, we screened genome-wide diversity in 211 individuals from surrounding Borneo. Surprisingly, characterized by a distinct, high frequency genomic component not found Malagasy. This novel layer occurs at low levels across Island Southeast Asia hints complex model for expansion this region. In contrast, Malagasy show links range groups, but do have clear connection with despite obvious linguistic association.
