The
trilobites that are also apparent in the
Cambrian period have an extremely complex eye structure. Consisting of millions of honeycomb-shaped tiny particles and a double-lens system, this
eye "
has an optimal design which would require a well-trained and imaginative optical engineer to develop today" in the words of David Raup, a professor of geology.
This eye emerged (in
fossil records) 530 million years ago in a perfect state. The sudden appearance of such a wondrous design cannot be explained by
evolution, since it has the feauture of "
irreducible complexity".
Moreover, the
honeycomb eye structure of the trilobite has survived to our own day
without a single change. Some insects such as
bees and
dragon flies have the same eye structure as did the trilobite.

WOooooooah.. easy on there Gritchka, Where did I get it?.. as rubbish as you may think it is, (lol and actually admittedly it ain't great) look again - it's quoted!.
As for getting a life - working on that, I'm still (micro) evolving.
