Some 6000 years ago, Austronesian peoples (descendants of the early Chinese) migrated into Indonesia, the Philippines, and New Guinea, where they encountered other societies that had been there for many thousands of years. How can we explain the different outcomes of these encounters in Indonesia and New Guinea?

They  share—to a varying degree—common cultural characteristics including widespread traditions and technologies like tattooing, stilt houses, jade carving, wetland agriculture, and various rock art motifs. They also share a common set of domesticated plants and animals that were carried along with the migrations, including rice, bananas, coconuts, breadfruit, Dioscorea yams, taro, paper mulberry, chickens, pigs, and dogs.

Explanation:

Today, no Austronesian languages survive in southern China. Nevertheless, based on linguistic, archaeological, and genetic evidence, Austronesians are most strongly associated with the early farming cultures of the Yangtze River basin that domesticated rice from around 13,500 to 8,200 BP. They display typical Austronesian technological hallmarks, including tooth removal, teeth blackening, jade carving, tattooing, stilt houses, advanced boat-building, aquaculture, wetland agriculture, and the domestication of dogs, pigs, and chickens. These include the Kuahuqiao, Hemudu, Majiabang, Songze, Liangzhu, and Dapenkeng cultures which occupied the coastal regions between the Yangtze River delta to the Min River delta
