The Wallacean islands have always been separated from Asia and Oceania by deep-sea waters. Yet, these tropical islands were a corridor for modern humans migrating into the Pleistocene Australia-New Guinea landmass (Sahul) and have been home to modern human groups for at least 47,000 years. The archaeological record attests a major cultural transition across Wallacea that started around 3,500 years ago and is associated with the expansion of Austronesian-speaking farmers, who intermixed with local hunter-gatherer groups. However, previous genetic studies of modern-day inhabitants have yielded conflicting dates for this intermixing, ranging from 1,100 to nearly 5,000 years ago.

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)
Wallacea is named for Alfred Russel Wallace, British nautralist (1823-1913), who came up with the idea of evolution independently of Charles Darwin. He discovered the Wallace Line, beyond which marsupial mammals dominated (as opposed to placental mammals on the near side of the line)--mainly New Guinea and Australia.
It looked to me that the Wallace line was about 1/2 way between mainland Asia and mainland Australasia (to use a British term for the continent).
Most atlases put all of the West Indies in North America (I found one that put Trinidad & Tobago in South America).
Their version of the Wallace line would put most of the Greater Antilles in North America and most of the Lesser Antilles in South America.
A number of Greek islands are closer to mainland Asia than they are to mainland Europe.
