We've definitively established that Clovis populations and all modern Native Americans are genetically related to Beringian populations out of Eurasia. It's reasonable to suspect pre-clovis populations probably came from much the same area, especially given that suggested pre-clovis lithics so closely resemble clovis traditions.
Additionally, the farthest east that we've found evidence of Australasian populations is the Solomon islands, some 7,000+ mi from South America. There's no evidence of habitation on the intervening islands until Austronesian peoples show up much later. As for Africa, we simply have no evidence for it whatsoever.

- AlotOfReading 5y agoThe authors' speculation that this was due to both populations originating in east Asia eventually turned out to be true once further work was done on sequencing Tianyuan man [1]. It's not indicative of Pleistocene trans-pacific contacts. [1] https://doi.org/10.1016/j.cub.2017.09.030 https://doi.org/10.1016/j.cub.2017.09.030
