However, these have been repudiated by studies using whole genome sequencing which has found that all ISEA populations had genes originating from the aboriginal Taiwanese. Contrary to the claim of a south-to-north migration in the "Out of Sundaland" hypothesis, the new whole genome analysis strongly confirms the north-to-south dispersal of the Austronesian peoples in the prevailing "Out of Taiwan" hypothesis. The researchers further pointed out that while humans have been living in Sundaland for at least 40,000 years, the Austronesian people were recent arrivals. The results of the previous studies failed to take into account admixture with the more ancient but unrelated Negrito and Papuan populations.
