:I agree, "now native" seems to be a contradiction in terms, and thus a joke. If it is left, it needs to be explained that native to a place means "has lived there for a long time" rather than "originated in".  For Australian animals, this is a particularly important idea.  [[User:Myrtle|Myrtle]] 01:06, 20 July 2007 (EDT)

::I've changed it to eliminate the word entirely (what do you think?), although the word "native" is interesting.  It's definitions include "being such by origin", which in effect assumes an evolutionary history, but which I doubt is always strictly applied anyway (e.g. the platypus would probably be considered native to Australia, even though fossil evidence shows that they existed in South America, which makes one wonder just what the evolutionary origin point was).  Another definition (admittedly not strictly applicable here) is "being or composed of people inhabiting a region from the beginning (Example: "''Native Americans''")", which begs the question, "the beginning of what?", and suggests that the word does not strictly have to mean from the beginning of (a) the continent of America, or (b) the beginning of humanity.  [[User:Philip J.
