So Timothy was lying

According to the article the females don't fare any better either.

I didn't know this about octopi, what's the point, evolutionarily, to self destruct after reproducing?

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.

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

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

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

[–] [email protected] 21 points 1 week ago (1 children)

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

Gooners win again

everything else is just random chance.

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 prevent decrepit politicians who already had their chance from usurping the resources of the next generation and pulling up the ladder behind them?

You know... Octopus politicians

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

[–] [email protected] 12 points 1 week ago (2 children)

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

[–] [email protected] 21 points 1 week ago (1 children)

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.

[–] [email protected] 6 points 1 week ago (3 children)

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

[–] [email protected] 1 points 6 days ago

Thank you, so far you're the only one addressing my question. The answer could very well be that it's a spandrel, but just like you said it would be speculation like anything else- nobody here daring to say "nobody in the scientific community has a solid theory, we don't know for sure"

[–] [email protected] 9 points 1 week ago (5 children)

As was said before: The genes are already passed onto the next generation. It doesn't matter if the parents become stupid now. There's no evolutionary advantage to become more or less stupid at this point.

It became like it is now by some random chance(s).

[–] [email protected] 1 points 6 days ago (2 children)

that's not how it works.

It is more advantageous to have more than 1 shot at spreading your genes than having only a single one.

Yes, your genes will be spread with just reproducing once, but they will be even more spread if you have a long and productive live with even more offspring

The YT channel primer actually made a video about rougjly this topic recently

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

[–] [email protected] 3 points 1 week ago

They also lay tens of thousands of eggs at once.

whatever works...

[–] houstoneulers 5 points 1 week ago (1 children)

I read that it's so the parents don't compete for resources with their young, helping to support the young's survival

[–] [email protected] 2 points 6 days ago

Fair, another possibility, thanks for the answer

[–] Scott_of_the_Arctic 4 points 1 week ago

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.

This happened to me. No joke. I lost half a standard deviation from my iq for each child i had. #dunceLife

Octopuses didn't get post nut clarity.

[–] [email protected] 63 points 1 week ago (2 children)

or maybe they do and it's unfathomable to the rest of us

Eldritch knowledge beyond our understanding

[–] [email protected] 24 points 1 week ago

Cthulhu was just a normal octupus that just kept on jacking off, reaching untold and forgotten knowledge, dooming this universe with his eldridge gooning

[–] Donkter 11 points 1 week ago (3 children)

Octopus nuts and it realizes it's mere empty space perceiving itself.
