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.
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
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).
