  what’s the point, evolutionarily, to self destruct after reproducing?

  There is no point, evolution is about successful reproduction and everything else is just random chance.

  If a evolutionary tweak happens that gives your off spring better chances, but your arms fall off after sex then it’ll probably perpetuate.

    Unless your species is a K Strategist where taking care of your offspring/group is essential.

      But that’s just moving the goalpost, so to speak. You’ve just built a different parenting framework that requires you to stick around. You’re still hunting the same goal: self sufficient offspring

        True, I’m just being pedantic and pointing out that “reproduce and that’s it” isn’t the case for some species.

        Some species carry it on to “reproduce and ensure your offspring reproduces too.”

    nope, then you’d see some of same species showing the behaviour, others not.

      Sorry I’m really struggling to parse what you are saying here 😄 my fault.
      Can you explain further?

        To my understanding:

        nope, then you’d see some of same species showing the behaviour, others not.

        Nope, then you’d see some animals of the same species showing the new behaviour while other animals, still of the same species, would not.

        Also my comment: We absoluteky see this, just on small scale tho. :|

    No that’s absolutely not true, every part of evolution happens for a reason and those we don’t know, we research until we find out why

    • JayDee@lemmy.world ⁨1⁩ ⁨week⁩ ago

      I think the point the other guy is pointing out, is that good and bad evolutionary traits are often connected - or more helpfully stated, evolutionary traits can have both benefits and drawbacks which don’t immediately seem related to the same trait.

      It’s quite possible that octopi sex dementia is just a drawback to another trait which is very beneficial, so the dementia was just a bad aspect of a good trait that propagated forward. This happens all the time in different animal biologies.

      • KeenFlame@feddit.nu ⁨1⁩ ⁨week⁩ ago

        No, that’s what I am saying. They are saying that it’s a random effect.

    Maybe them dying is the bonus, eliminating the old blood.

  • x4740N@lemm.ee ⁨1⁩ ⁨week⁩ ago

    Wouldn’t it make them easier to he hunted by prey or just die from not being careful

    People with dementia can end up getting themselves fatally injured so I don’t see an octopus can’t

    So I don’t see how it’s beneficial to help them survive

    • helpImTrappedOnline@lemmy.world ⁨1⁩ ⁨week⁩ ago

      It’s not but, the evolutionary goal is compete.

      There’s no way for the octopus to pick a mate with out the side effect, so the lack of post-nut clarity continues through the generations.

• roguetrick@lemmy.world ⁨1⁩ ⁨week⁩ ago

  Essentially their entire mating cycle is what causes this. They’ve got a gland behind the eye that puts them into mating mode and once it starts it never turns off until they overdose on sex hormone.

• Contramuffin@lemmy.world ⁨1⁩ ⁨week⁩ ago

  There’s a specific life history strategy called semelparity, which is what you’re describing (breeding once then dying). To my understanding, this is incentivized if the chances of getting a second attempt to breed are too low, and so it becomes more evolutionarily advantageous to simply go all out on the first attempt

  source

  • Mothra@mander.xyz ⁨1⁩ ⁨week⁩ ago

    Thanks, one solid answer! It could be that it used to be an advantage at some point and now it’s just perpetuated

    source

    • roguetrick@lemmy.world ⁨1⁩ ⁨week⁩ ago

      To be clear, it’s still an advantage and for the ones that it isn’t they don’t die after mating. Most cephalopods are both predators and prey that life cycle results in a very high mortality rate. The really big ones though, like giant octopuses, have to work so hard to get so big that they tend to not die after mating.

    Semelparity: “Fuck it, I’m gonna nut to death”

    source
  • perestroika@lemm.ee ⁨1⁩ ⁨week⁩ ago

    Yes. A bit similar process in sea-dwelling salmons: migrating from salt water into fresh water (quite a big metabolic challenge in itself), traveling up rapids to suitable spawning places (often a long and arduous journey)… after they’ve accomplished that, their chances of returning alive are quite low. So they mostly die. But river-dwelling trouts spawn many times in life, because their migration isn’t as costly.

    I would suspect that something in how octopuses mate has an element of “return being costly” - it could be a metabolic return to the feeding and growing state instead of a physical return.

    source
  • omxxi@feddit.org ⁨1⁩ ⁨week⁩ ago

    That makes sense, if there is an organism that is a very good predator, and the chances to breed a second time are too low, then if the organism doesn’t die it will be consuming the resources of those who can breed. Natural selection must prioritize having descendents over long living, because not having descendents is extinction.

  Not everything in evolution ends up having a point. So long as a problem does not impact the propagation of children it can end up moving forward to the next generation.

  I would guess that if there is an Evolutionary reason, it’s probably that octopi with this drive reproduced More than octopi that didn’t.

  • UrPartnerInCrime@sh.itjust.works ⁨1⁩ ⁨week⁩ ago

    They reproduce so much because they forget they had already done it and believe they need to do it or else

  Evolution doesn’t care what happens to you after reproduction because you’ve already passed on your genes at that point

  source

  • SkaveRat@discuss.tchncs.de ⁨1⁩ ⁨week⁩ ago

    I mean, yes, but if you’re not a vegetable afterwards, you will have more chances to reproduce. Therefore passing on your genes more

    source

    • Transtronaut@lemmy.blahaj.zone ⁨1⁩ ⁨week⁩ ago

      Evolution doesn’t make deliberate, strategic choices. Random mutations result in new behaviors/properties that may or may not be beneficial, and selection removes those mutations that prevent reproduction from the gene pool. Not every mutation will be beneficial, but as long as it’s not harmful enough to stop reproduction, it can persist.

      If there were two groups of octopuses, one with the self-destructive behavior and one without, then there would be pressure from competition. In that situation, your point would have more of an impact. But without that pressure, there’s nothing to drive the selection. And the mutation won’t occur just because it would be helpful for it to do so - it’s random.

      At least, that’s how I understand it. I’m not a biologist or anything.

      source

      • SkaveRat@discuss.tchncs.de ⁨1⁩ ⁨week⁩ ago

        yes, that’s the point I’m trying to reinforce. There has to be “a reason” that getting stupider after mating is a succesful trait, otherwise it wouldn’t be there.

        The question that was asked was: what is the reason? So far I’ve only seen speculation in this thread

      yeah but octopi are intensely successful hunters. this may be either a mechanism that helps prevent resource scarcity, or it could prevent parent/offspring mating

  Reproduction is the goal. It could be as simple as giving the young a chance to out compete their r****ded parents for limited food.
