Who cares if DOS is in XP? It is still the case that the development is by design. The designers are the programmers, not DOS. The point here is that tools with one purpose at one point of evolution serve another later, and that a partial system can still function - just at a different level. this is true, designed or otherwise. I wasn't talking about the 'design' matter here, just the fallacy that incremental changes are not advantageous. I am amazed at the development of a functioning wing. And, again, I do not think it would have happened randomly. It is not random in the sense of dice. there are advantages to reach - to insulative coverings - to flexible arms - to gliding - to soaring - to diving - to flying. It's evolved in multiple insects, in fish, amphibians (partially), reptiles, mammals and birds... it works a little differently each time, but the effect is similar. But it is not 'random' - the advantages are the same each time, and given enough generations life will change and use them. And the more complex the animal, the more ways it may test and develop the advantages... hence all vertebrate phyla have at least evolved a glider. Flying is an advantageous survival trait, and the better it gets the more the advantage. It's common just as walking on the pavements is a common survival trait: randomly, we walk all over, but it's not a coincidence that the survivors are the ones who don't get hit by cars.
