Here, we provide new insights into this region{\textquoteright}s demographic history based on genome-wide data from 16 ancient individuals (2600-250 yrs BP) from islands of the North Moluccas, Sulawesi, and East Nusa Tenggara. While the ancestry of individuals from the northern islands fit earlier views of contact between groups related to the Austronesian expansion and the first colonization of Sahul, the ancestry of individuals from the southern islands revealed additional contributions from Mainland Southeast Asia, which seems to predate the {\textless}br{\textgreater}Austronesian admixture in the region. Admixture time estimates for the oldest individuals of Wallacea are closer{\textless}br{\textgreater}to archaeological estimates for the Austronesian arrival into the region than are admixture time estimates for {\textless}br{\textgreater}present-day groups. The decreasing trend in admixture times exhibited by younger individuals supports a {\textless}br{\textgreater}scenario of multiple or continuous admixture involving Papuan- and Asian-related groups. Our results clarify {\textless}br{\textgreater}previously debated times of admixture and suggest that the Neolithic dispersals into Island Southeast Asia are {\textless}br{\textgreater}associated with the spread of multiple genetic ancestries.}}, journal = {{Nature Ecology {\&} Evolution}}, volume = {6}, pages = {1024--1034}, }
