Experts explore new mushroom which causes fairytale-like hallucinations

Perhaps human-like creatures are so common in drug hallucinations because we're human, social animals, creatures who are maximally interested in other humans. If you gave drugs to dogs then perhaps they'd see human-like things mixed with dog-like things. I assume crocodiles, solitary animals, would see nothing besides wounded fish or maybe sexy female crocodiles.

>Caffeine increases pareidolia

I like that coffee is clearly a drug, a mind-alterer. But it's mostly harmless so it's been boosted as a sort of society-wide mascot. Humans really love drugs.

There are some flowers which produce tiny amounts of caffeine in their nectar, apparently to give the pollinators a buzz.

> how to square the idea that evolution produces knowledge with the idea that it doesn't optimize even for reproductive fitness

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).

In stark contrast to what you're claiming, I have absolutely zero patience for intelligent design and the likes -- that’s exactly my point.

All I'm saying is that the whole point of the theory of evolution is that blind enumeration of mutations is not required, and that combinatorial feasibility emerges in spite of the vastness of the search space. It is already well known that mutation bias exists, so none of this is controversial.

Multiple commenters here have already explained this from different angles, including chemical and environmental constraints (PaulDavisThe1st), developmental and functional constraints (Supermancho), and even software analogies like coverage-guided fuzzing and genetic algorithms (BobbyTables2). These are not fringe ideas; they are standard ways of explaining why your "astronomical search space" framing is a strawman.

You are hedging; I am not trying to weasel word or distance myself from evolution, or use red-flag rhetorical "I'm not $1, but $2" devices. I have read, agree with, and acknowledge the other replies to your message, because I understand that evolutionary theory already fully explains the concern you're raising.

Your claim that "blind enumeration of mutations seems combinatorially infeasible due to the vastness of the search space" flatly contradicts the theory of evolution.

This has also been directly challenged by other commenters asking you to justify the alleged combinatorial barrier in concrete terms (uplifter), and by others pointing out that genomes do not need to traverse all possible combinations to move between viable states.

The entire point of evolutionary theory is that blind enumeration is not required, and that combinatorial feasibility emerges from selection, heredity, population dynamics, and cumulative retention of partial solutions. No "woo" is required.

Evolution is blind with respect to foresight, but not blind with respect to feedback, structure, or retention.

Mutation bias, developmental constraints, and non-uniform genotype–phenotype mappings are foundational components of modern evolutionary biology, not ad-hoc patches.

People who doubt evolution tend to rephrase it into a strawman -- "random bit flips over an astronomical search space" -- and then declare that strawman implausible.

Several replies here explicitly reject your framing. For example, thrw045 points out the massive reuse of structural templates across species, and PaulDavisThe1st notes that only a small fraction of DNA even codes for proteins, further undermining the idea of a uniform, unconstrained search.

Your "I'm not pushing intelligent design, but evolution seems combinatorially infeasible" move closely mirrors the Discovery Institute / "teach the controversy" pattern: disclaim ID, then introduce a doubt-claim based on a strawman of evolution as uniform random search, then retreat to "just asking questions." That strategy is explicitly, insincerely, and unintelligently designed to manufacture doubt about evolution while insisting it is not religious.

We can see the sealioning pattern play out here in real time: repeated insistence that ID is rejected, followed by reiteration of the same mischaracterized impossibility claim, even after multiple substantive explanations have already been given.

I’m not hedging like you are here: evolutionary theory does not claim "blind enumeration over an astronomical space," and treating it that way is simply a misstatement of the theory.

I think I and other people recognize your rhetorical patterns and misunderstandings, even if you don't, thus the downvotes. Other commenters have fully addressed your doubts about evolution. To me, the big give-away was your "I'm not $1, but $2" wording.

In any case, this is a thread about psychedelic mushrooms and hallucinations, so if some machine elves want to weigh in with some woo about population genetics, I suppose that’s fair game.
