re: biology as geology clue

Hey Brandon,

I was beginning to wonder when I would hear from you again—glad you wrote something, even if it was just a link. :)

Cute little bryozoans... Don’t know what the article had to do with evolution, but it does seem to give at least indirect evidence that global warming isn’t manmade.  If the ice sheet collapsed once before, presumably due to a warmer climate, one can hardly blame that earlier warming spell on mankind and industrialization—something else had to have caused it.  A variation of that something could have caused the recent warming trend (which apparently has reversed itself in the past decade).
