Sea travel dates back forever, and I'm never surprised where castaways and sea drift end up.
Btw, they have a new Kon Tiki out.
the only thing that resonates with me from the thesis (which he borrowed) by the Philippino-American author is his premise that migrations from mainland Asia and/or it’s nearby islands to points east and south were neither one-off events or one directional
that I have always believed
and though that author cannot and does establish real proof of it, nor can I, it makes more sense
than believing that no matter how some persons migrated or how far that migration was, that no one ever wanted and no one ever managed to return back to where they had migbrated from, and that others did not learn about how to do that, and over time some of the migration did not go forth and some back as well, and some in new directions and from new places to older new places - forming known trade and migration routes over long expanses of time
the idea makes “human sense” to me
the human mind has not grown in thousands of years; the genetic wiring for the brain’s nueral net has been there a long time; humans have always been smart, inventive, creative, curious, determined and willing to change
it may have taken us a very long time to develop our tools from pre-stone age to now, but we have always been very smart at using the tools we did knew about, and even long long ago we did some amazing things with them too
“trade networks” across vast land and ocean expanses??
sounds to me like something any of age of man would accomplish in some way
