Bertvan: Hi Cliff,
New biological systems and body parts due to parabiosis, Siamese twinning or
integration of symbionts. While I don't full understand any of these, they
sound like biological innovations whith the complex function already
assembled and in working order. Why would they need "natural selection"?
While it is true, they might all arise without ID, how DO they arise? How
WOULD a duplicated gene turn around and suddenly start performing an
entirely different function? I'm not trying to pick an argument. I really
want to know.
