Right, hopefully (but hope springs eternal), we can bash this one up under the umbrella of "Philosophy". (heh) So here goes. There are some amongst us who Some people say: "red has no purpose". To which I reply But: "however, red is purposeful"; red does have purpose. The purpose is to do that which said thing does. Things that have the property of "being red" behave as if they are red. This (obviously) is how we distinguish between red things and others. Everything in the word exhibits behaviour of some sort, non-red or red. So those who believe (apart from actually saying) that red is without purpose - "does not exhibit purpose" - I ask: what do red things do, that lets you (someone who doesn't distinguish purpose), determine that they are in fact, red? Aren't you just deluding yourself believing in the "purposelessness" of red? Are you trying to distinguish between the questions: "why (for what reason) does red exist ?" and "does red behave purposefully?". Or do you see no distinction? (Actually they are the same question) P.S. Purposive and purposeful are synonymous, purpose is something that things with purposive behaviour have.
A moron. Does a moron have any purpose....? If you found a moron, wandering around all by themselves, what would you think? Is a moron any use? What purpose could anyone find for such a thing...? Pr'aps a moron is a thing that thinks (why this is, has never been determined) there's such a thing as a colour, (they might do something completely moronic, like calling it "red" - ???) But that's a moron for ya.
Adaption is overrated. A bat with a trunk the size of an elephant is much less likely that one with a slightly bigger nose than it has. Architecture.
Aha. But Life designs its own architecture...? If it makes a mistake in the design stage, what happens?
Red, I would argue, does have purpose. But only as it relates to our ability to interpret its cause. Thanks to the doppler effect, we know light that is stretched into the part of the spectrum we see as red is emitted or reflected from objects moving away from the observer. That of course is how we know that distant galaxies are moving away from us. The implications are well documented.
You mean there's a blue end to the spectrum too. There has to be relativity. The red shift isn't a doppler effect, the light from distant galaxies is stretched because the distance has increased while it propagated through space, so it gets stretched too.
