Some trilobites didn’t have that problem. They had double-lens systems that made the corrections for underwater vision....
I forget - where did trilobites live, again? On land, like scuba-ing students do??? Or, perhaps,
under water??
Jeez, Mike! If that's the best AIG can do, they are worse than I remember them being!
"The Christian church, in its attitude toward science, shows the mind of a more or less enlightened man of the Thirteenth Century. It no longer believes that the earth is flat, but it is still convinced that prayer can cure after medicine fails." H L Mencken
