New FTDNA ethnicities

FamilyTreeDNA updated their DNA ethnicity guesses. (Yes, guesses, the science behind them is nowhere near exact)

My current breakdown is on the left.

I am aware that the trace results are so small that they can easily be false-positives.

However, is that Siberian indicative of my alleged maternal Native American ancestors who may have come over on the land bridge?

My mother's current DNA breakdown is on the right.

She doesn't have the trace Siberian. Is it possible that it is from my Paternal side? What about the Oceanian and Iberian?

I haven't encouraged my father to be tested as I assumed it would be 100% Jewish Diaspora/Eastern European, and the high number of false-positive cousin matches for Jewish DNA makes it less useful as a tool for finding cousins.

The odds are that my trace results are false positives, but still, perhaps I should get someone on my paternal side tested to be certain.

My Middle Eastern ancestry is clearly maternal. Ancestry (see below) still defines it as "Caucasus" and indicates it could also be Romanian, which suggests that it comes from my Transylvanian maternal grandfather.

Both Ancestry and FamilyTreeDNA suggest a trace of Pacific Islander/Oceanian. That's rather unlikely, but it does appear in both places, and is a very intriguing possibility.
