I have confirmed Papuan ancestry by DNA testing. Did the Papuans travel to the Philippines in their Lalakois?

Where and which Filipino group did you come from? The ancient inhabitants of Southeast Asia were related to Papuan people and I believe they were the majority until the "Mongoloid" people came and assimilated them. In the Philippines, Papuan or Melanesian genes is higher among some indigenous tribes like Negritos and Manobos. It also makes up a minor portion of lowlander Filipino genes, it gets higher as you go south.
