Charles Darwin
wrote about one orchid that he came across that there must a moth in
the area with a proboscis longer than any previously discovered,
because the flower shape requires it. Decades later, another scientist
finally found the moth that Darwin had never seen, but knew must
exist.


For anybody interested, this was shown on the Nature three part series Deep
Jungle, episode 1, New Frontiers. Basicly just the blurb about Darwin and
a the guy hunting down the orchid and staying up all night with a camera.

I have to roll my eyes at this series, though. PBS trying to be hip. @-|
