genetic facts [was: Ashby, botanical facts

[Paul D. Roughan]

Has anyone seriously proposed a hypothesis of polynesian origins in SE
Asia, travel to SA, and subsequent return voyages?

Or:

SA arrival at EI first, followed by polynesian arrival,
warfare/assimilation and continued contact with the rest of Polynesia.  
EI (to this amateur) seems impervious to one-origin analysis - 'South
America OR SE Asia'.  Of course, its a lot harder to falsify this sort
of hypothesis, which may be too close to 'ad hoc-ness' for scientific
enquiry.
