Yeah, they really are.Our last two posts are not mutually exclusive.
Which is very much not what I wrote about. I wrote about genuinely new functions.Corrupting information which specifies a particular function CAN create a 'new' function.
Again as in the example of a bear losing pigment in it's fur. The non pigmented/white fur provides a useful new 'function' as camouflage in the arctic.
As I already wrote, we have abundant empirical evidence that both random mutations to existing proteins and completely random peptides can and do yield novel molecular functions -- e.g. protein binding of new substrates, catalysis of new reactions. You believe that random mutations don't produce new functional information, but you belief is simply wrong. I'd be happy to walk you through some of the studies if you're interested.And crucially an evolutionary dead end; additional random corruption will never restore the original functions; pigment in the bears fur or a complete new exhaust system- the entropy works in one direction only, towards decay, degradation, regardless of whether that degradation happens upon an advantage in certain niche environments along the way.
