Metamorphosis

Its mostly allowing to use different niches and in butterflies it allows adults to go on and do their thing without having to feed anymore.
Different stages with diapause also allow to develop and change niches in accord with predators' development rythm so the spiece avoid it as much as possible.
Mind that there are relict hexapods with no methamorphosis during development and hemimetabola so youve got a full spectrum.
Having a pupa allows the spieces to just wait out shit times and remodel themselves so it gives a tremendous advantage.

Also evolution led to you mate so having a pupa isnt as unbelivable in comparison.

What's really fucked is that they did some study to see if they could retain memory after metamorphosis. Don't remember the details but they would coach the caterpillars to respond negatively to a specific stimulis, then confirmed that as a butterfly it responded in the same way. So when it liquifies into goop inside the Chrysalis it still retains memory somehow.

Part of the trial-and-error method (also known as brute force computing) is trying out possible solutions without requiring a logical reason, or predetermining that it will in any way form a functional path to a specific outcome. Since the efficacy of any particular life morph is determined by factors outside of the butterfly's own physical body, within the environment, predetermining that a particular life morph will match environmental conditions is not necessary anywhere in the butterfly's life code; the environment is a puzzle, and the butterfly has many pieces.

Think of evolution not so much as a creation event, but a deletion event. Butterflies which did not have the proper pieces were simply taken out of thr picture. That's why they are able to evolve multistage life morphs, such as metamorphosis, without requiring onboard intelligence. It's not that the butterflies planned out their evolution, but rather that the environment predetermined the extinction of any butterfly that couldn't randomly guess the correct steps to enter a multistage life morph.

The intelligence to affect this process is within the universe, and this is also the physical location of the intelligence which designs life morphs through evolution. Other universes without conscious life forms exist, but all the time in those universes passes instantaneously, because consciousness is the process of observing time over time. As a result, all conscious life forms exist within universes which were by their design predetermined to evolve life morphs which allow for the existence of conscious life forms to emerge as a related cause to the primary effect of that universe's creation event.

If a universe wasn't predetermined to evolve life morphs of any kind, then you wouldn't exist to observe a moment of time within that universe in which it didn't.

We don't Jellify in pods at age 18 and become a completely different creature.. it's easy to see how we evolved from our ancestors, but I cannot wrap my head around the idea of metamorphosis being possible evolutionarily. What were the intermediate evolutionary stages?

>>19262714
But how can such a process which is so complete evolve gradually by mutation as evolution has us believe? Did one worm decide to half wrap it's self up which somehow helped it survive? How could gradual evolution have possibly created a situation where disintegration and reassembly occurs? Disintegration is all or nothing, how could there be a intermediate form?

>>19262723
Immobile larval stages - still present in some group. Some final immobile larvae are exremely pupa-like but levae nontheless some are just immobile larvea and everything inbetween. At some point more and more developmental processes were pushed into that final larval stage.
>>19262723
Its not that they jellyfie in total. Some tissues and whole systems stay intact during the process and dont require complete rebuilding.

>>19262738
Its not complete disintegration. The insect doesnt decide shit,but yes become a immobile piece of trash and developing more and more parts of adult body in that form is advantageous and was pushed for.

>>19262749
I understand how it would be advantageous, but I can't see how it could randomly happen to begin with. Is it a relic of molting? It's not like an animal being born with a different fur pattern or extra webbing between it's fingers and toes, it's complete transformation mid-life into a different organism.

Neither did the butterflies.

But if not seeing a future event before it occurred actually stopped unexpected things from occurring, then you wouldn't be a consciousness individual capable of knowing the difference between past and future events in the first place; everything would blur together in a singular moment across all time.

Ill gey back to you anon. Cant write right now.

Evolution isn't limited to gradual changes. By virtue of being randomly selected, evolution can evolve complex sequences of interdependent events as well. It just requires more energy, and so extreme changes require more time to manifest. They are every bit as possible, though. If evolving taller hind legs is required to reach a certain fruit that needs to be eaten in order to observe the moment in which a universe exists for which an organism evolved those taller hind legs within, then an organism WILL evolve those taller hind legs, because there is no time to observe universes in which such a fruit was not eaten.

If the fruit is a metaphor regarding the observarion of self aware consciousness with respect to time, and a physical strain of caterpillar evolving a multistage metamorphosis is required in order to serve as a metaphor and living example of chaos theory in action for intelligence of an organism with tall hind legs to evolve in order to reach the fruit of knowledge which allows the observation of this moment of YOUR existence, HERE and NOW, then that caterpillar WILL have evolved in order to do so. The intelligence comes from the fruit.

The fruit evolved you.

>>19262637
It can't. Evolution is just a theory. One day it will be stretched so thin it will break, and then we'll have to find out what actually happened.

Son, you really need to lay off the fucking weed.

I am actually quite sober.

Thank you for bumping this thread.

Metamorphosis is fairly exclusive to insects and a handful of invertebrates, and amphibians.

Insects, frogs, and certain invertebrates have developed incredible survival tools because they are very successful organisms that adapt quickly and are prone to mutations due to the sheer volume of species, sub species, and the large numbers in which they are spawned. All due in part to their short lifespan and very successful mating habits in many species, leading to almost exclusively the most successful survivors getting to mate.

An example and tl;dr

Two humans and two beetles locked in two seperat room's and with infinite food.

Two humans will roll the genetic dice once or twice a year

Two beetles will roll the genetic dice a few hundred times in the first 3-4 months.
