A review paper by Melinda A. Yang (in 2022) summarized and concluded that a distinctive "Basal-East Asian population" referred to as 'East- and Southeast Asian lineage' (ESEA); which is ancestral to modern East Asians, Southeast Asians, Polynesians, and Siberians, originated in Mainland Southeast Asia at ~50,000BC, and expanded through multiple migration waves southwards and northwards respectively. This ESEA lineage gave rise to various sublineages, and is also ancestral to the Hoabinhian hunter-gatherers of Southeast Asia and the ~40,000 year old Tianyuan lineage found in Northern China, but already differentiated and distinct from European-related and Australasian-related lineages, found in other regions of prehistoric Eurasia. The ESEA lineage trifuricated from an earlier East-Eurasian or "eastern non-African" (ENA) lineage somewhere in South Asia, which also contributed to the formation of indigenous South Asian hunter-gatherers (AASI) as well as to Australasians.[5]
