Fellow Wallaceans, as your leaders, we assure you that you are not being replaced by Austronesian- and Papuan-related groups!
“These results also confirm that the genetic ancestry of Wallacean hunter-gatherers has been largely replaced.”
I had to look it up, Wallacea is part of Indonesia. From widipedia:
Wallacea is a biogeographical designation for a group of mainly Indonesian islands separated by deep-water straits from the Asian and Australian continental shelves.Wallacea includes Sulawesi, the largest island in the group, as well as Lombok, Sumbawa, Flores, Sumba, Timor, Halmahera, Buru, Seram, and many smaller islands
(Sulawesi is the big island that looks like a spider monkey, at least to me)
