This has been known for at least a decade. https://westhunt.wordpress.com/2013/01/15/a-three-hour-tour/ https://westhunt.wordpress.com/2013/01/15/a-three-hour-tour/ >Here’s a scenario. A ship from some Indian civilization about 4000 years ago [maybe Indus] loses its way and ends up crashing on the shore of Arnhem Land. Like most ships, its crew is all male. They survive the landing, and end up warring with a local tribe. Eventually, they kill off most of the men and annex the sobbing women. The new tribe has 5x higher carrying capacity, essentially due to better technology, and they’re militarily superior as well – better weapons and tactics. They expand and expand, picking up more and more old Australian genes as they do so. Not as an empire – they’re too simple for that – but the tribes that descend from them keep winning. They speak the ancestor of the Macro-Pama-Nyungan languages, which originates as a mix between their old-Dravidian language (from the men) and some local Australian tongue (from the women). >One funny thing about this scenario: the sailors lose almost all of their civilization, and probably thought they were descending into savagery. On the other hand, the locals probably thought of the castaways as incredibly advanced, magicians or gods. They were both right.
