The idea that modern humans in SE Asia, in the Holocene, were more advanced than Pleistocene predecessors, has taken a bit of a knocking – as a result of research by the Australian Research Centre for Human Evolution (see https://phys.org/print410447018.html ). The discovery of cave art, said to go back up to 40,000 years ago, on the island of Sulawesi, and various tools etc, seems to show that Ice Age humans were as advanced as those in India and elsewhere.
