Species that lack significant levels of genetic diversity have a big problem. And it's not just about ending up with tiger and kiwi bird versions of Cletus the Slack-Jawed Yokel. Beyond the risk of inbreeding, genetic diversity supplies the tools that help a species adapt to change. If there's not enough of it, then the species is more likely to die out when subjected to stressful conditions ... like, say, climate change.

    Just a minor note – the correct name is just ‘kiwi’.

    Saying ‘Kiwi bird’ is a bit like saying “Bald Eagle Bird”.

    Heh “Kiwi bird”? Writer (or audience) must be from the east side of the ocean. (No points for guessing that). I’m going to file the awkward clarification under ‘comeuppance for the provincial dropping of the last syllable of “kiwifruit”‘ (which was named for the bird).
    The trade-off is probably worth it, since Americans probably speak of the fruit more often, and fortunately the habit doesn’t seem to have reached passion fruit :-)

      Passion fruit is not generally consumed in the US except in restaurants where the white truffle flan with passion fruit aioli appetizer sells for $37.
