I've told people off for using the pathetic fallacy too, in the past, I guess I just said "what do mushrooms want" for the sake of rhetoric. Well, because it would be funny. Fine then, I was trolling.

Thanks to your discussion though, I'm now wondering how to square the idea that evolution produces knowledge with the idea that it doesn't optimize even for reproductive fitness. I think you're technically incorrect there: it's that it doesn't optimize exclusively in the short term or by any one obvious strategy. The bottom line is that what survives survives, though, you can't argue with a tautology. Even if what survives is a sloth or a sleeper shark or a bristlecone or (imagine) a single infertile but incredibly tough organism, it still had to find a way (alright, stumble into a way). Maybe your objection is just that "optimize for" implies intent, but intentless-purism in language for biologists is as hard as pastless-purism in language for time travellers.

Its really fairly simply: natural selection requires two things: heritable genetics and a source of variation in the genetics between individuals. Mutation is the most basic source of variation, and that produces new information. But new information isn't necessarily knowledge. Assuming a scientific testing gloss, each new genetic code variation X can be considered as a hypothesis, that "variant X is fit", and then natural selection events that act on copies of X (for or against) serve as experiments testing the hypothesis. Through iterative experiments, we weed out the copies of the variants where the hypothesis of them being fit was proved by natural selection to be false, and what remains should be those copies of genetic variants which have (mostly) proven to be true. Learning and understanding which variants are fit (where the hypotheses are true) is knowledge, and in this way evolution produces knowledge while not having any optimization goal (in the intent sense, which I agree is a requirement for something to be meaningfully "optimizing" anything, because you can't aim in a direction without a sense for that direction).

    this is the problem i have with natural selection... it has no predictive power. You can never use natural selection theory to say if an organism is "fit" before it exhibits its fitness. what good is this?

I laughed!

"What do mushrooms want?" Is hilarious given your evolution context!

Sometimes, it can make sense to step back and laugh.

The number one response to words we do not like is righteous indignation.

It is almost always a bad idea too. Funny that!

Humor can be powerful as can giving benefit of doubt followed by one or more probing questions.

Amazing conversations often follow.
