>The Tianyuan lineage can be modeled to have emerged by a Paleolithic admixture event between a primarily Onge-like source from Southeast Asia (c. 61%) and from a deeply diverged East Eurasian source associated with the IUP movements into Siberia (c. 39%), which were distantly related to the Bacho Kiro cave remains. An earlier model estimated around 64% ancestry related to Eastern Asians and 36% ancestry represented by the deeply diverged Ust'-Ishim man, who represents an "early leaf on the East Eurasian tree", close to a trifurication between West and East Eurasians
>Basal East Asian or "Deep Asian" ancestry represented by Tianyuan or Andamanese Onge contributed to the Peopling of Southeast Asia, following deeply diverged Australasian ancestry and preceding Mesolithic and Neolithic expansions of Ancient Southern East Asians associated with the spread of Austroasiatic and Austronesian languages
>Major East Eurasian ancestry lineages which contributed to modern human populations include the following:
>Australasian lineage (AA) — refers to an ancestral population that primarily contributed to human populations in a region consisting of Australia, Papua, New Zealand, neighboring islands in the South Pacific Ocean and parts of the Philippines. Represented by present-day Australasians, e.g. Papuans and Aboriginal Australians, as well as the Philippine Negritos
>The Tianyuan man also shares more alleles with South American populations, such as the Surui and Karitiana in Brazil and Chane in northern Argentina and southern Bolivia, than with other indigenous Americans
