Before 8,000 YBP, most South Indians appear Australoid – they looked something like Aborigines. Vietnam was Australoid from at least 18-21,000 YBP. This type looks Melanesian. They slowly transition to Mongoloid over time, and the transition was only completed 2,000 YBP. In some SE Asian groups, the transition from Australoid -> Caucasoid was not complete, and here you can see the Indonesian or Malay type.
