I'm curious about this one. I have no doubt that this is an accurate quote, but my first thought was "what about symbiosis?" - so I googled the quote... and guess what... I came across numerous creationist sites using this very idea (symbiosis vs this quote) as evidence of the defeat of Darwinism.
As I am not the sharpest knife in the drawer, I wonder if any of you could explain to me how this is NOT related to symbiosis, OR, why Darwin would revise said quote were he alive today?
And... to stay on topic...
Having seen this argument come up sooooo many times, I question the very use of the word "designed" as an adjective. All the definitions are inadequate to answer this debate. It's like we need to split the word into two versions, one meaning "designed by an intelligent agent" and the other "ordered and structured".
