In the study of "The Dual Origin of the Malagasy in Island Southeast Asia and East Africa: Evidence from Maternal and Paternal Lineages" shows the Bantu maternal origin to be 38% and Paternal 51% while the Southeast Asian paternal to be 34% and maternal 62%. In the study of Malagasy, autosomal DNA shows the highlanders ethnic group like Merina are almost an even mixture of Southeast Asian and Bantu origin, while the coastal ethnic group have much higher Bantu mixture in their autosomal DNA suggesting they are mixture of new Bantu migrants and the already established highlander ethnic group. Maximum-likelihood estimates favour a scenario in which Madagascar was settled approximately 1,200 years ago by a very small group of women of approximately 30. The Malagasy people existed through intermarriages between the small founding population.
