https://www.youtube.com/watch?v=ZzpY3gJgXQwI'm conviced that evolution can be triggered by individual wishes of an animalHow does a caterpilar out of "infinite clothes in their closet" chooses one that resembles almost perfectly, the one, just the one that scare their predators?If this were the only animal that did this, fuck fine, randomness, it happens. But it keeps happening and happening far more times than randomness can statiscally account for me to say "it's not random" there's a decisive element lying in the fabric of reality that makes a caterpilar(and many other animals) look like a snake(or others).But what is this decisive element?Food?Chemicals?Consciousness? I personally think it's this one.
>anon accidentally invents Lamarckian evolution
>>16479734Just looked up and it doesn't seem to follow my logic...I'm saying that some stuff about evolution the animal can decide the starting point and even the ending point at some level regardless of inheritance
>>16479756That makes even less sense than Lamarckian evolution
>>16479760kek as long we agree evolution is not purely random i'm finealso rereading the image i sent i can see why you called lamarckian evolution,you're right it's pretty similar to what i described if we consider the blacksmith the starting pointit also came to me that maybe the caterpilar came in contact with the dna of the snake its trying to mimick, which still doesn't exclude the animal "decision" or whatever
>>16479724looks like a caterpillar to me
>>16479724>How does a caterpilar out of "infinite clothes in their closet" chooses one that resembles almost perfectly, the one, just the one that scare their predators?There were other caterpillars, but they died out because they didn't scare their predators, and thus they were killed to extinction.That's how evolution and natural selection work.(At least I think so - I'm not a scientist.)
>>16479724>>16479794A caterpillar doesn’t have the brain capacity to make decisions like that, it doesn’t even know what a snake actually is. Lots of caterpillars already do threat displays where they puff themselves up and wiggle around and lots already have eyespots, from there it’s just a few steps to looking like a snake. If they could intentionally decide how to evolve then they probably wouldn’t pick such a gamble as mimicking a tiny snake which is a small vulnerable prey animal itself
>>16479724natural selection in caterpillars is weirder than that. There is one set of genetics for becoming the caterpillar, and then, another set takes over, that makes them form a cocoon and turn themselves inside out again, into the butterfly. The genes that make this happen isn't voluntary, it's more like having a virus that makes you devolve and mutate, a virus that doesn't ask, by the way, it acts mercilessly and probably painfully although I don't know for sure. The decisive element that drives natural evolution is the hybridization of DNA, by sexual recombination, but also, random mutations and viruses. All this combining and recombining and infecting drives random events where something sticks. Many species operate with several sets of chromosomes, many plants are like this. Plants are in some ways more amenable to rando mutations, acquiring genetics. If you think about it, a plant has to wait around to have sex, but genetic material is all over the place. Why not get a little side action? For animals, its not too different: they may be carrying other organisms, and viruses, that interface to influence total surivability and phenotype, like gut microbiota in humans. Without gut microbiota, we'd die. Without mitochondria, that was probably survived beging swallowed by our ancestral single-cell precursors, we'd die. Our genomes are full of evidence of viral infections which inserted themselves into our genomes, and we have lots of enzymes that look like they evolved in parasites, that do similar things that "our" genes do, rearranging things in our genomes, sometimes with randomly bad effects. Our ancestors were riddled with parasites living in our bodies. Today you have Toxoplasma in all the cat owners, doing stuff in their brains. Theres a lot of DNA out there, a lot of copy/pasting going on, a lot of opportunity to add a lot of change and complexity at the molecualr level. So a bug that looks like a stick isn't that surprising.
>>16479811>A caterpillar doesn’t have the brain capacity to make decisions like that, it doesn’t even know what a snake actually is. I'm painfully aware of this, I'm talking about a extremely minimal level of consciouness/stimuli that is sufficient enough to take decisions and understanding of its surroundings>If they could intentionally decide how to evolve then they probably wouldn’t pick such a gamble as mimicking a tiny snake which is a small vulnerable prey animal itselfWhat's the best thing the caterpilar could mimick if it could in your opinion?It can't be a bear or a lion because spiders other insects are not scared of them>>16479812>>16479801yea i'm going back to darwin evolutionthanks for the discussion anons
>>16479874For further discussion without this moron, who will forever be stuck inside the "not educated, knows nothing, can't ask questions correctly" paradigm, look into:chemistrybiologyentomologygeneral biologymolecular biologybiochemistrygeneticsphysics
>>16479935board is full of these physics/math faggots that think they can theorise shit about biology like it's some kindergarten field where their uneducated opinion is worth shit. When I ask questions about a field I know nothing of I may very basic questions, but at least I don't pretend I know the answers to things people smarter than me have studied for decades, these faggots' arrogance disgusts me. Pretty sure it's just high schoolers or undergrads though.
>>16479874>spiders other insects are not scared of themSpiders aren’t scared of snakes either. That mimicry is to deter birds and other vertebrates, and it’s not always going to work. There’s no best thing they can mimic, just what works enough to be worth developing
